Doctors are regularly incorrect as well and its hard to say whether or not they're your best shot at solving a problem. It really depends. I would say consider all the information you're given, including videos on the internet, as they can easily teach you things about a problem that doctors/nurses simply don't have time to explain. Though, having a doctor's opinion won't hurt... probably.
Doctors aren't trustworthy either, they fuck up all the time. Best strategy would be to listen to multiple doctors and consider the opinion of the majority but that's rarely viable.
Best thing you can do is vet doctors and find one that has your best interest. Some care about your well-being. A lot are legal drug dealers and your body is a walking cash cow. Do your own research. We all have the ability to critically think. Use it! Only recently we have been told to not research and give up total anatomy control. You only have one body. Guard it with your life. Otherwise you won’t have one.
There is this book I recently finished reading its called The 21 Former Doctor Secrets, Its full of secrets about modern health industry and my routines started to change so much! I appreciate people like you and these good doctors!
"The next time you are burning up and feeling bad, rest easy knowing that your enemies are having a much worse time than you" is such a good way of putting it and makes my current fever feel much, MUCH better >:)
It's helps feel some power and control, when you get sick and feel the fever starting, look inwards, think of the sickness that's annoying you, and wish: "burn"
Whenever I get sick and feel terrible I always try image that my body is a battlefield where my immune cells are slaughtering the infections, somehow it makes me feel better haha
Me : *gets infected My immune system : "Don't worry. These microbes can't survive above 40°C." Me : "But I also can't survive above 40°C." My immune system : "I missed the part where that's my problem."
The immune system is like a bully that got surgically attached to you, except its been there since the moment it got established in your body in your mother's womb.
One of my favorite facts about the body: in most minor sicknesses, most of the symptoms you feel aren’t the bacteria infecting you, but your body fighting back.
One of my mind blowers was the fact that most diseases aren't named after the specific germ they are named after the symptoms your body has or the location. I always assumed that doctors looked at your symptoms, diagnosed your problem as this specific virus and gave you the medication for it. Nope! They often just treat the symptoms or use broad antibiotics and hope the body fights it off. A lot of medicines are to counteract the side-effects of the other drugs you are on if they are really nasty. My daughter was less than a day old and was rushed into the NICU. She spent several weeks fighting an unknown infection. They never figured out what the infection was and said she had Sepsis. I looked up what Sepsis was and it's basically the body hurting itself from fighting an infection.
@djones02 Yes, especially most of the first line of drugs, just treating the symptoms. Not even antibiotics. It has its risk to use antibiotics. I always googled the drugs I took, learning how they work. It's very interesting.
@@djones02 The concept of germs is very new historically speaking, not even 200 years old. Medicine has existed for thousands of years before that. Without a clear understanding of the root causes of sickness, it makes sense to assess things by what can be observed.
@@djones02yes. Most diseases can be cured by our own body. Doctors give medicines because people complain about the symptoms (because of the unpleasantness or they need to work). Hence the medicines are symptomatic rather than definitive. Only a few diseases actually need definitive therapy. Some other diseases are literally incurable and the only thing we can do is prevent the progression.
Pro tip from experience. And I barely get fever and it’s not super bad if I do. Wrap yourself up. With loads of water next to your bed. Sweat it out. Help your body with increasing your temperature while not exhausting the energy resources. Plenty of hydration and in one night fever is gone. Even do this for common cold. Sniffles? Sore throat, coughing? Anything cold related. Wrap up in bed, hot tea, sweat it out. And you’re good as gold in no time. Told this tip to a colleague, she had an ongoing cold for couple of weeks. No fever. I told her to sweat it out. Next time I saw her. She felt the difference. 😊👍 I’m with fever on this one. Will keep in mind to avoid anything with meds in it. Just vitamins and tea 🙌
“Speak to your doctor, and don’t listen to internet videos” this is one of the best lines ever because only a channel that actually wants to help you and is the best would tell you not to listen to them and listen to professionals instead.
They should absolutely be disclosed in the beginning. Before the video starts there should be a few second cut where they disclose every sponsor since they can be conflicts of interest. Then the real ad after the video ends.
I remember I got a fever during exam season. Since I needed to do work, I could have taken fever suppression medicine but I said to my body "fine, whatever it is, let's kill it so we can move on". I put on a jacket, got a heavy blanket (duvet) and went to sleep for 6 hours. It's the fastest I have cured a fever and I was back to work like normal.
same, especially during summer sometimes I can't tell if I'm just overheating/early heatstroke or have a full blown fever. It doesn't help that I have sinus issues and brain fog somewhat regularly. Typically though I tend to be on the _power through_ team for the first few days because I don't like taking more than the necessary amount of any medication, I'd rather not develop a resistance while I'm still young and not dependent yet, I've seen too many family and friends suffer more from a resistant due to hair-trigger mediating.
Not only fevers, but also incredibly bad intestinal cramps. I'll always remember my two hardest experiences. Reaching 41.5, hallucinating, wetting everywhere i went and unable to distinguish reality from a dream was a walk in the park compared to my worst abdominal pain, thinking im dying cuts it VERY short lol.
This. I've never wanted to take fever medication for this exact reason, but 9 times out of 10 have to because my fevers get dangerously hot. As a kid it was really bad and my doctor (who we knew personally very well) actually gave me a personal temperature where I had to go to the ER higher than the normal one, because otherwise even under medication literally every illness would be hot enough to send me to the ER when it didn't have to
I had the flu a year ago and couldn't sleep during to the fever. Avoiding fever reducers was something I was told to do because fever fights infections, which makes sense. I spent a few sleepless nights in absolute misery, almost feeling more sick with each day that passed. It actually took administering some ibuprofen to settle the fever enough to get some rest, which helped me recover much quicker. I hope people understand that despite fever being an important immunological response, sleep is still necessary for recovery. If your pain is too great, please take something for it. You'll probably feel better and recover faster. :)
I would say sleep is even more important than fever. Each time I have gotten a fever, no amount of medication and variety of medication helped me recover. Only long amounts of sleep helped me recover extremely quickly. I would even suggest taking melatonin, but only if you aren't alone and someone else can monitor your temperature, otherwise taking a fever reducing medication would be better to be on the safe side.
Exactly this, I let fever run through the day, then take medication at night so that I can feel better and be able to sleep and rest. There’s a balance to everything.
Pretty much what I wanted to say. I let fever run during the day, but taking something to help sleep usually makes me feel better than suffering through the night
Well, for most of the world I'd say - go to the doctor and follow their advice. Usually, it's the same as the video suggested - if your fever is over ~40C take the anti-fever medication, otherwise don't, but if the fever lasts more than a few hours straight to the point when you cannot rest - contact doctor for further advice. It's normal and expected to have a bit of a problem with sleeping or rest when sick. If it's too much probably there is a reason for that which needs to be investigated. Wharever effected you was likely not "just" common cold (adeno/rhinovirus), there is no way to know now. You most likely started using the drug when the infection was almost over but the immune system lags behind. Have you done it firsthand, the story could have been very different. Unfortunately if you are in a country where healthcare is unaffordable (like US), or ineffective (like China) or just does not exists (much of central Africa) you're on your own to judge how to proceed. Each situation is different, and so is treatment.
Dude, as a ER Registered Nurse, this content is so good it should be translated in every language and broadcasted in every National TV across the globe!!! Thanks Kurzgesagt!!! As always phenomenal video and content!!!
Well they do have channels in different languages where their videos are narrated in.. well.. different languages. But, sure, it could still get nore exposure on other media.
@@Tim_Sviridov Yeah, a bit like the english archers in "BraveHeart" " But, Sire, if we order the archers to shoot again, they´ll be also hitting our own troops!" - " Yes. but we have reserves. They don´t"
this animations look so badass. we literally have everything: skulls, big ahh flames, "blood becomes lava". i seriously can't watch this without saying "hell yeah!"
Every time I get sick I watch all your videos on the immune system or the body’s defenses in general. It’s the best thing I can do for myself because it gives me the biggest sense of confidence I could have when sick, knowing that my enemies are getting massacred to the very second. I’m sick as I type this
I don't think any song released has ever not been able to be a stand alone song. Epic Mountain Music really hit the nail with the video about the scale of stars.
When I was in my 20s, I had a fever of 41C for about 2 days before I was taken to the hospital. It was so bad I was hallucinating. The dr said that less than 1C higher and I would have started getting brain damage. Later, when I was in the army; I suffered from heat stroke a few times and my body has never been able to regulate my temperature properly since. It really sucks. Imagine not being able to work out, do things you used to enjoy, or even just go outside on warm days without instantly getting sick and throwing up because your body can't tolerate a temperature just a few degrees above normal. The difference between a fever that someone can just get over and one that can be severe enough to alter your life is so close that it is better safe than sorry and just go to a dr.
to you have the same problem with cold temperatures? many things can be fixed with specific kinds of therapy, not sure if your problems can fall into that.
I’m so sorry you have to deal with it. I have temp regulation problems due to a genetic thing. I hate summer because of it, and I live in the Southern US. I basically have to stay inside all summer and even going to a doctor’s appointment is really hard; I had a fever for two days after getting out last time. I also have chronic pain and heat helps, but if I fall asleep with the heating pad on, I wake up with a fever, soaked through, and miserable. But because of my other health issues I also get fevers just from stress. I had a fever for three months straight before my wedding, during the height of COVID, so I couldn’t get my dress altered for the longest time. People seem to not get how much it impacts what you do. I don’t even like eating very hot food (especially soups or pasta or mashed potatoes) because I’m hot for like an hour after I eat. It’s ridiculous!
Bro... Anything above 103F and you really should be taking meds. At 41C you should have went to the ER literally right then and there. It's unfortunate that you waited 2 days. I had a fever, when swine flu hit, for a week that was like 103F to 104F and we went to the ER for that shit. 😅
Feel for you there im the same due to having to take immune depressents no protection from anything a cloudy sunny day now feels like the desert sitting in the garden swells my eyes shut due to the pollen actual bubble boy nowadays 😂
I'm questioning my health right now. I rarely get a fever, but I'm easily too hot. I sweat massively and every time I do sport, especially cardio, I'm feeling sick afterwards and get a really bad head ache that can stay for two days. Always wondered what that's all about.
The magic of the solutions is mitigated by the idea that there were 100 billion of us who have lived and died as trial and error of just our species, and seriously countless others of our progenitors before them. So a fine tuned system makes total sense with virtually any solution to any issue. But the enormous magnitude of "effort" getting us to here is still quite incredible all its own.
There's a video by kurz that tells all possible microbes in life even those that aren't discovered yet to man have an antithesis. In theory, one can survive literally every single pathogen, including the absolute deadliest, provided the immune system knows how to deal with it. The problem lies on the fact that the immune system doesn't have the knowledge on everything. It can create the solution and it has all the tools, it just doesn't know how to do it.
It is so complex. I took 1000mg of Paracetamol in one take (2000mg is max daily usage) and felt better after 90minutes, the odd thing was my temperature stayed the same for next 6 hours (measuring every 1h using analog thermometer)
The other main issue is time... some infections and diseases overwhelm the body quicker than it can activate the counter measure. Its that week, week and a half period where you're body is identifying and making the anti bodies that gets ya... if the invader can do lethal damange to you in that time, then you're screwed, which s why Ebola and the like is so bad... before you're ready to fight back you've taken to much damage to vital organs to survive.
One thing I’ve learned from pharmacy school, is that if you are ever unsure as to whether you should use an anti-pyretic (anti fever) drug such as Tylenol, you can always contact your local pharmacist and they can give you some guidance such as whether it’s ok to stay home and rest vs. should you go to the doctor. They can also advise you on when you should and shouldn’t take Tylenol or other anti-fever medications. While I am not comfortable going over the guidelines I’ve learned in school here since I have not yet passed my NAPLEX (the USA pharmacy national certification exam) I am comfortable saying that part of a pharmacist’s training involves multiple courses in “self care therapeutics”, which involves steps to identifying what is and is not an immediately refer to doctor type of illness. I wish everyone here to stay happy and healthy and please wish me luck as I continue with my pharmacy training ^^
The idea that fungi were a “great filter” that led to the evolution and dominance of warm-blooded mammals on Earth was put forth by my PI, Dr. Arturo Casadevall (timestamp 1:07). So happy to see his work make it into my favorite YT channel!
I'm 16 yrs old, and I've never really tought about what makes me passionate for studying University, but oh gosh, these videos about cells, viruses, inmune system, and the whole microbiology topic gives me chills of excitement! I love this. Thanks to all the Kurzgesagt team!
@@rundown132 Its not always about money. Money ≠ Happiness. Performing valuable research in such a field is worth lots, also for ur own mental health (depending on ur mindset)
these videos are seriously the best science education ones I've ever seen! my teacher in middle school would show these to the class and I loved them. now I'm watching them on my own. great work!
UA-cam content creators can now do A/B testing with thumbnails, so it occasionally switches the thumbnail to see which one gets the most views and finally settles on that one. I think that's what the OP did, they designed 3 thumbnails to see which one works.
yup, as markus said it's almost certainly just them uploading the video with a few thumbnails and you randomly get served one or few of them. Kurzgesagt has been doing it for a while now.
@@markusTegelane Sounds great on paper, but I only clicked it because I noticed it changed and was curious why The older one with the fiery arm was better
The sad part of all of this is that in this current age and society, nobody actually cares about your health, only your productivity, so your recovering time be damned and just "feel good" while you're sick so you can actually work
Unless you are a stroke patient or have had a traumatic brain injury, in which case an infection and high fever can cause seizures. Sepsis is something to watch for in these patients.
"speak to your doctor and don't listen to internet videos" is really the best advice they could have possibly given lol. Great video. The immune system is so fascinating.
@@solame10101 so here should have been the video. "We have no information to share with you about the immune system, we are not licensed doctors. If you would like to know about the components and functions of the immune system, ask your doctor."
Kurzgesagt, you once said in a 10-year-old video, "We will make a separate video talking about tectonic plates in general." I'm still waiting to this day. The video, in particular, is 'Everything you need to know about the earth'
there will be parties in the streets, endless fanfare, glorious banquets when Kurzgesagt makes a video about general tectonic plate knowledge. I am waiting with you.
I had 39.7c fever that almost knocked me out and wasn’t able to cool down. nurses injected cold electrolytes water in the vein for three consecutive hours, at the temperature your eyes teared, ears humming like there’s a bird inside your head, your shiver doesn’t have feeling at all, but you can see your bed shaking in high frequency like you’re electrocuted. It’s like a daydream that has no ending, time passes slow af.
When I was a kid, I had a really bad 40c fever for a couple of days (maybe longer or shorter, I can’t remember), following a 39.5 fever for a week before then. I’m not sure what it was from, I didn’t get treatment for it but it was some waterborn pathogen, as far as I could guess (there was something being spread by water fountains around the area.) My foster parents at the time refused to get me to the hospital, so I’m honestly surprised I didn’t get critically ill or anything. Shit was awful: I was throwing up all the time, dehydrated, I couldn’t move and when I did my body felt so heavy I felt like I was gonna collapse. My eyes burned like hell, my head hurt every time I breathed in, and I was hardly eating too ‘much since I just couldn’t hold it down. The shakes from that were terrible, I remember not being able to hold much since it was just vibrate out of my hands lmao.
The shaking and weakness are the worst Your bones feel like over cooked pasta and your muscles like the gelatin to the point that even standing up feels like it is a challenge
When I was in the military in 2014 I discovered that going into the sauna when I was sick expedited my illnesses. I rarely stay sick for more than 72 hours now.
Saves your body generating the heat with it's own resources! Great for mild illnesses, but important to identify when it's something you can't get over on your own
How adorably you've spoken about our natural science of healing! I stopped taking pills for fever and acute diseases many years ago. Never felt the requirement. 2-3 days of rest and juices is all it takes, and it feels like a deep cleaning of the system. Immunity is stronger.
do you think the succulent chinese meal was a reference to the guy made famous for quoting it, "What is the charge? Eating a meal? A Succulent Chinese Meal?" who also recently passed away?
i was a sickly kid. would have permanent colds and coughs for 7-8 months a year, and only getting better in the summer. i always forgot to take meds and just kept rawdogging my illnesses. i was also a dirty kid too lazy to focus on hygiene. years later, as an adult, i never get sick. a few weeks ago i got my first cold in 4-5 years, and it passed within 2 days without medicine cuz once again, i forgot about them even though i bought them. this made me realize that perhaps relying on meds only means ur immune system loses the opportunity to become stronger. i have friends who regularly get sick, or have random headaches, or something else randomly hurting. i cant remember the last time i had a headache
You are semi right, medicines are best to fix the inmune system doing stupid stuff that is self destructive or to control out of control infections that you can't fight back. Well and vacciness which are like training manuals for your inmune system so it can get strong before even being infected, usually this is good for disseases that leave bad permanent side effects even if your inmune system can eventually defeat the main dissease or for disseases that kill you before your inmune system can fight it back. Most medicines are symptomatic to make yourself functional by disabling sysmtoms that your inmune system created to fight, this actually makes the illness slightlyt worse but allows you to not have to rest even if you feel like shit longer.
@@diablo.the.cheater yeah i def get vaccines. and one time when i was a kid, i got this SERIOUS illness (idk what its called in english) but its like a flu but on steroids. i was basically puking out green phlegm by the jar-fuls, and was hospitalized, getting injected with an unknown substance regularly. in that case, meds def helped me i think. but for ur average illnesses, like a common cold or a fever, i feel like taking meds only harms u in the long run. unless ur immune system is so weak that u have no choice but to take meds
I think the same, my grandma and mother used to take pills (to combat fever) always and soon I realized they needed more everytime. Something inside my mind told me that wasnt good so I started to take medicine only when I can barely think, refusing theirs offers. Now when I get sick (like amost never) I take 1 pill when feeling TOO bad and get better. I didnt even got COVID or if I got it never realize it was (never feel too bad like my friends told me it was, or lost smells or taste). The only thing I suffer a lot is bacterial tonsillitis, there was a time I got ill every other month, detected it was when I smoked in outside cold nights. That was like 5 years ago. Remember one time I got 39C fever for like 2 days and cant even open my eyes or think, still didnt take medicine for fever only antibiotics. Now my girlfriend works with little children so she is ill almost everytime (in winter) and take a pill for almost everything. When she infect me I get one day mildly ill and then restored. I get people take medicine to keep being functional but I think is bad on the long run. Luckily I have a job where I can say I feel bad and they let you rest for the day without medical license.
3:16 “Imagine running a marathon, while eating a succulent Chinese meal, and giving birth” A sentence that I would’ve never expected to hear from Kurzgesagt
1) As an ER Nurse, thank you 2) Complaints & litigation are heavily tied to why we try to get rid of everyone's fever. 3) Fever's are still hard on your body so there is a balance. 4) Medicine is tricky, but fixing symptoms is the quickest way to make you feel better....even if you don't feel any better. 5) Did I mention thank you?
@@Dr.EdwardClint if we DON'T deal with someone's fever. Especially children. Can't say for sure it's lead to litigation but definitely complaints and ire.
@@matthewmurdoch6932 Thank you for clarifying. This is why I think this video is wonderful. Many, perhaps most people do not understand the role of fever. When it comes to children, fever is thought to be more important than in adults (and why theirs are higher): they haven't been alive long enough to train their immune system against common pathogens in their environment. The don't even yet have the full array of antibodies (this takes until around age 10). So the body has to rely on the means available. But I also 100% understand with parents who are watching their kid suffer and assume that must be the worst thing, even if it isn't. =/
@@Dr.EdwardClint fever kills many children esp in places like morroco where its already hot and there isn't much AC, it can cause organs to get stuck together and a whole host of other problems leading to the children dying - and the government is so corrupt they will not care and the healthcare so bad, there is no help.
I remember my little daughter had lots of fevers when she was small. And seeing that platypus being so weak, unwell and shivering brought tears to my eyes. Poor thing. Very well animated and designed.
I dont think most adults are suppressing fever because they feel bad but rather because they need to get back to work and a lot of places dont let you into the office unless your temp is low enough.
The last time I was properly ill, I developed a pretty intense fever. I called out of work, but since I work in a right-to-work-for-nothing state in the US, my work told me I either had to go in, or go to the doctors right then and there. It was the middle of summer, and feeling lethargic and miserable, I got into my car. Almost instantly I stopped shivering, felt way more lively, and stopped wishing for my life to end then and there. The inside of the car was boiling hot, usually I start expiring instantly, but I drove all the way to the doctors with the windows up and the AC off, and felt almost like I wasn’t sick. Didn’t sweat a single bead. I’m not saying this was a good thing to do, I’d much rather have stayed in bed and continued wishing that the world would have the decency to stop existing for a few moments, but it was an interesting phenomenon.
The way my family treats fever is the second it seems you have one you are COVERED in blankets and forced lukewarm liquids not allowed out untill you're better, so normally 1 to 2 days. It is usually a warm heaven but if it's caught early it feels like hell😅 I swear by this method, I think "helping" your body stay warm and retain the heat gets the healing process done in a timely manner
It's your skin shivers that make the fever way worse. If you can keep your body warm enough to reduce stress of your body producing the heat, you can get rid of the shivers and some of the lethargy. Another way I love is to take a near scalding-hot shower for 5 minutes. No shivers, skin pain is gone, headache mostly gone. But, you should definitely lie in bed afterwards because hot water can trigger your body to cool down.
Yeah, just have medical saunas for sick people. It doesn't make sense not to do it. And the sauna place could sign a doctor's note to get you out of work. It seriously is nonsensical that no one in the medical industry has thought of this.
@@Vegetable_____V I wouldn't consult a doc over a regular fever. If it goes above 40 degrees or lasts for a prolonged period, then consult a doctor. Or if you're immunodeficient.
For me, the most unpleasant thing about fever is the fact that sometimes it makes you unable to get some zz’s. Your body temperature will drop naturally whenever you go sleep and yet your body does the exact opposite of it. Very upsetting indeed.
i'd be fine with all the symptoms if they'd LEAVE MY THROAT ALONE throat pain is the worst pain you can experience when your sick. idc, give me migraines, give me shivers, give me nausea, but do not hurt my throat.
I had a food virus last week. Going to the bathroom so many times isn’t great but it helps know that your body is just trying to “detox” itself despite the discomfort. Just kept myself hydrated and well rested till I felt healthy again.
I had covid for the very first time last year. No fever, but my blood pressure and heart rate was sky high, I felt dizzy for a couple months, and I had constant diarrhea. I survived. I caught covid again a few weeks ago, and I had a fever for a couple days, and a mild dry cough for a week. I have no doubt that my body knows how to deal with covid now.
Same. The first time I got covid it was hell. I had an awful fever, lost about half my taste and all my smell, muscle cramps, dizziness, shortness of breath (which was scary cause I have asthma). Whole thing lasted for almost a month. Second time it wasn't that bad at all. Only sick for about 10 days, but everything was much manageable. Never felt so proud of my body kicking butt (also glad for that vaccine, worked wonders).
Thank you. I needed to hear this because my little boy just had a febrile seizure from a fever and I'm a PTSD mess right now. Knowing the fever has a purpose helps so much
Most of the feel bad symptoms are your body actively waging ear against the infection. From sinuses swelling to slow down invaders, mucus to trap them, stomach being purged in either direction to flush them out. Not pleasant and can absolutely get out of hand and always consult your doctor but that's the origin of it
@@tioswift3676 Then I must be stupid! But I think there's a lot of people who thought as I did, which would seem to be an argument against it being "basic" knowledge. Basic for medical students, maybe. Not so basic for most people. You should feel very smart!
@@macsnafu As a CS who's always been rather poor at biology, it's definitely very basic knowledge of fever. It's just that most people don't have very basic knowledge of fever.
Fr, this video is so ugly (comparatively). In a world of Sam O Nella copycats trying to make the most heinous shit they could, Kurzgesagt's artstyle was an oasis in a artistic desert. Hope this doesn't sticks.
is it just me or fever just hits different. like having fever on a winter/christmas evening, chilling on the couch/bed and having some good tea and treats is just my core childhood
@CatHelicopter you can look up "succulent Chinese meal" and the video of the legendary meme will definitely come up, alongside likely the news of the man in the meme's death a little over a week ago.
@@CatHelicopter its an old clip from the 90's where this guy gets falsely arrested while eating a succulent chinese meal and he starts his iconic dialogue during the arrest
There is a bit of an issue in this video, (*sorry I hate to be that guy I know you all work really hard to research this topic*), and don't get me wrong I love a good evolution-defying system, is that while Fever IS difficult to adapt to, it's not even marginally difficult enough to justify why Fever is so ubiquitously effective in nature. Some context for this; Microorganisms evolve orders of magnitude faster than we do, and the evolutionary arms race between those who adapt for high temperatures or low temperatures does exist of course, but that explains only the statistical likelyhood of being infected by fever-resistant bacteria. But if you noticed, we almost never encounter fever-resistance in bacteria, which doesn't make sense unfortunately for the theory, because the expected result should be rarer instances of slower-spreading viral infections who are fever-resistant. That's not to say that the theory posed in this video isn't widely accepted, it is, but that doesn't make it correct. An extremely important context-clue that should indicate why this theory is fundamentally flawed is stated earlier in this video. As you mentioned, there are many microorganisms that can adapt and even thrive in much, much higher temperatures than we could EVER produce inside of our bodies. Another, and even more troubling consideration for this theory, and in the same slide as the previous one; These microorganisms have demonstrated that they can adapt, do adapt, and can even thrive in very wide temperature ranges, including the entire temperature range that our bodies are capable of. So, you might be asking, why is high fever-resistance such an unusual adaptation? Here in lies the part that you guys missed in the video, its not about the adaptations nearly as much as it is about the thermodynamics of microscopic life. Let me explain, the vast majority of evolutionary adaptations change the proteins that the organism will produce in a given set of circumstances, it is absolutely essential to all organisms to produce proteins that are suitable to their environment, not only so that protein itself can function, but to restructure the non-protein systems appropriately when the environment changes. All biological systems (proteins, receptors, signaling molecules, DNA, membranes, etc.) function under an optimal temperature, and going outside this temperature can quickly cause systems to slow down, fail, or even disintegrate, which is why most cells have redundent systems AND can ensure Homeostasis by quickly producing a new, or altering an existing system when they detect a change in conditions. But to do so, they essentially out-mode the entire system that existed before the change, while having to produce a new one, and this is a very energetically expensive process for the organism. Multiply that process by the number of failing systems and you can see why microorganisms get "Stressed" by the heat changes in a fever, particularly because microorganisms are so competitive that they prioritize optimal conditions and NOT rapid-adaptability. This also answers why our temperatures only have to change a few degrees, the AMOUNT of heat change is relevant only to the extent that Microorganisms "optimal" conditions are violated, forcing them to invest resources in producing new systems, we can't actually exceed the RANGE they could adapt too, and we don't have too, we only have to change it JUST enough to force them out of their comfort zone. It all circles back to thermodynamics; the problem is not ADAPTATION as much as it is ECONOMY. As said in the video, our bodies have vast energy stores that can be exploited to drastically raise the temperature of our bodies, but ALSO have lots of energy reserves so that OUR cells can create all the molecules and new proteins necessary to adapt to the new, very hot environment. This is NOT the case for our parasitic guests, Microorganisms have a very limited resource pool, even IF they were already adapted to be capable of changing into a more heat-compatible form, they still need to expend resources, resources they don't have, to USE those adaptations. Here lies the reason that Fever can be such a small shift in conditions and is still so universally effective. It is simply a one-sided battle of SIZE, a game of attrition that the tiny microorganisms CAN'T win unless they can kill us and eat us faster than they die. Our bodies enter energy-starvation the moment fever hits, it becomes a battleground with our cells over the resources that both they and our cells need to adapt and survive. Additionally, the parasites must not only survive but also reproduce very quickly in order to not be wiped out by our immune system, so as stated in the video, they have to reproduce, kill us, and adapt at the same time. One important part of this is that fever fluctuates throughout the day you're sick, going from very hot to almost normal body temperture, and this causes the invaders to constantly have to sink more resources into this process than just changing once. To conclude; Microorganisms cannot overcome Fever, and it is not primarily due to competitive evolutionary pressure as stated in the video. Fever is not really about defying Microorgansism's ability to adapt, its actually attrition warfare, the Microorgansisms are Napolean and your body is 1812 Russia.
I think the video explains it pretty well. Bacteria that adapt to resist fever don’t function as well in a healthy person. It’s a classic stabilizing selective force where they stay in a specific range because adapting in either direction is a disadvantage.
From a doctor's perspective: always take your fever medicine as prescribed if prescribed on time. Certain fever medication in combination with antibiotics can also reduce inflammation. Reducing inflammation early on can help reduce damage and recovery period. It might be a good idea to rest anyway and stay warm when on fever medications. Inflammation early treatment can reduce recovery to 3 days/immediately for something that could have been 10 days, a month, or chronic/permanent.
agreed. Generally speaking viruses will rarely shoot up above 39-40C and are probably the best bugs to maintain a fever for especially if it doesn't interfere with sleep. Bacterial infections are more amenable to antipyretics because of the link to inflammation which helps with the delivery of your antibiotic and reduces the chance of cytokine storms. In that case controlling the fever outweighs the downsides (bacteria are also less affected by fever). Fever that doesn't go down with antipyretics (or lasts more than 3-5 days) is also likely to involve a more serious infection and needs to be kept on top of as it could shift towards mengitis, septicaemia, pneumonia etc. The reverse is also true it may be the case that you have no fever but still have a very serious infection so it's not a golden rule...always ask your dr/second opinions for decisions involving health.
Kinda agree with you and Damn so confused! Should we take fever medication or not? Is it net beneficial to take fever medication with slightly weekend immune system or not take and have better Immunity?
@@VaibhavSharma-uu1om Think of fever like an optimisation for a "normal" immune system to gain additional benefits... However, there is no general advice for an abnormal immune system, because the effects will be different depending on the abnormality. For example a hyperactive immune system can benefit from antipyretics, but a hypoactive/senescent immune system may benefit more from fever. It all depends on the exact root cause and your status etc. It's why you need a dr to make this decision for you.

Doctors are regularly incorrect as well and its hard to say whether or not they're your best shot at solving a problem. It really depends. I would say consider all the information you're given, including videos on the internet, as they can easily teach you things about a problem that doctors/nurses simply don't have time to explain. Though, having a doctor's opinion won't hurt... probably.
Doctors aren't trustworthy either, they fuck up all the time. Best strategy would be to listen to multiple doctors and consider the opinion of the majority but that's rarely viable.
Best thing you can do is vet doctors and find one that has your best interest. Some care about your well-being. A lot are legal drug dealers and your body is a walking cash cow. Do your own research. We all have the ability to critically think. Use it! Only recently we have been told to not research and give up total anatomy control. You only have one body. Guard it with your life. Otherwise you won’t have one.

great advice from a video on the internet :)
huge paradox what do i do
@@mesutmyildirim ask a doctor
Imagine if they said, "talk with climate professionals and don't listen to internet videos about environmental change effects."
I once asked my doctor about taking meds for fever. He was categorical that not taking them is pointless suffering.
One of my favorite facts about the body: in most minor sicknesses, most of the symptoms you feel aren’t the bacteria infecting you, but your body fighting back.
One of my mind blowers was the fact that most diseases aren't named after the specific germ they are named after the symptoms your body has or the location.
I always assumed that doctors looked at your symptoms, diagnosed your problem as this specific virus and gave you the medication for it.
Nope! They often just treat the symptoms or use broad antibiotics and hope the body fights it off.
A lot of medicines are to counteract the side-effects of the other drugs you are on if they are really nasty.
My daughter was less than a day old and was rushed into the NICU.
She spent several weeks fighting an unknown infection.
They never figured out what the infection was and said she had Sepsis.
I looked up what Sepsis was and it's basically the body hurting itself from fighting an infection.
@djones02 Yes, especially most of the first line of drugs, just treating the symptoms. Not even antibiotics. It has its risk to use antibiotics.
I always googled the drugs I took, learning how they work. It's very interesting.
@@djones02 The concept of germs is very new historically speaking, not even 200 years old. Medicine has existed for thousands of years before that. Without a clear understanding of the root causes of sickness, it makes sense to assess things by what can be observed.
still feel like shit
@@djones02yes. Most diseases can be cured by our own body. Doctors give medicines because people complain about the symptoms (because of the unpleasantness or they need to work). Hence the medicines are symptomatic rather than definitive. Only a few diseases actually need definitive therapy. Some other diseases are literally incurable and the only thing we can do is prevent the progression.
It may sound stupid, but there's nothing like covering yourself with a blanket when you're sick. It's comfort heaven.
And nothing is more comforting than burying ourselves under the ground
Unless you have ADHD. Whenever I'm sick, it feels like my body is trying to outrun the infection
I prefer covering myself with a blanket when I'm not sick, but you do you
IKR MAN I LOVE THAT FEELING OF COMFORT
Thats exactly the opposite of what to do for a fever, but gonna do it anyway
Pro tip from experience. And I barely get fever and it’s not super bad if I do. Wrap yourself up. With loads of water next to your bed. Sweat it out. Help your body with increasing your temperature while not exhausting the energy resources. Plenty of hydration and in one night fever is gone. Even do this for common cold. Sniffles? Sore throat, coughing? Anything cold related. Wrap up in bed, hot tea, sweat it out. And you’re good as gold in no time.
Told this tip to a colleague, she had an ongoing cold for couple of weeks. No fever. I told her to sweat it out. Next time I saw her. She felt the difference. 😊👍
I’m with fever on this one. Will keep in mind to avoid anything with meds in it. Just vitamins and tea 🙌
“Speak to your doctor, and don’t listen to internet videos” this is one of the best lines ever because only a channel that actually wants to help you and is the best would tell you not to listen to them and listen to professionals instead.
Ask 10 doctors and get 10 different opinions, as said in the video there are not really enough evidence to support it 100% what's better or worse.
I feel like Kurzgesagt had to put that line in there
Any Drs in the house to verify or deny?

@@droxynormalwhat?
I remember I got a fever during exam season. Since I needed to do work, I could have taken fever suppression medicine but I said to my body "fine, whatever it is, let's kill it so we can move on". I put on a jacket, got a heavy blanket (duvet) and went to sleep for 6 hours. It's the fastest I have cured a fever and I was back to work like normal.
almost like listening to what you body needs is a good idea
The same thing happened to me once in college. It is like the body knows it has to recover faster.
Damn you basically turned your immune system into agent 47
@@nickwhright5848 Ikr. Humans should do that more often. At this point, our body is smarter than... we are
Remember, it’s if your fever is under 104° F that it is not dangerous. If your wrapping up gets you above that you could do permanent damage 😮
After 5 days of body aches and fever from the flu, I couldn't take it anymore. I took medication. I felt better that same day.
As someone who's always run a bit warmer and has seriously bad fevers, always walking a fine line between "I'll manage" and "I think I'm dying".
same, especially during summer sometimes I can't tell if I'm just overheating/early heatstroke or have a full blown fever. It doesn't help that I have sinus issues and brain fog somewhat regularly. Typically though I tend to be on the _power through_ team for the first few days because I don't like taking more than the necessary amount of any medication, I'd rather not develop a resistance while I'm still young and not dependent yet, I've seen too many family and friends suffer more from a resistant due to hair-trigger mediating.
real
Not only fevers, but also incredibly bad intestinal cramps. I'll always remember my two hardest experiences. Reaching 41.5, hallucinating, wetting everywhere i went and unable to distinguish reality from a dream was a walk in the park compared to my worst abdominal pain, thinking im dying cuts it VERY short lol.
@@101falconresistance to what exactly? Ibuprofen?
This. I've never wanted to take fever medication for this exact reason, but 9 times out of 10 have to because my fevers get dangerously hot. As a kid it was really bad and my doctor (who we knew personally very well) actually gave me a personal temperature where I had to go to the ER higher than the normal one, because otherwise even under medication literally every illness would be hot enough to send me to the ER when it didn't have to

@@julius43461what a low quality ragebait
I had the flu a year ago and couldn't sleep during to the fever. Avoiding fever reducers was something I was told to do because fever fights infections, which makes sense. I spent a few sleepless nights in absolute misery, almost feeling more sick with each day that passed. It actually took administering some ibuprofen to settle the fever enough to get some rest, which helped me recover much quicker.
I hope people understand that despite fever being an important immunological response, sleep is still necessary for recovery. If your pain is too great, please take something for it. You'll probably feel better and recover faster. :)
I would say sleep is even more important than fever. Each time I have gotten a fever, no amount of medication and variety of medication helped me recover. Only long amounts of sleep helped me recover extremely quickly. I would even suggest taking melatonin, but only if you aren't alone and someone else can monitor your temperature, otherwise taking a fever reducing medication would be better to be on the safe side.
Exactly this, I let fever run through the day, then take medication at night so that I can feel better and be able to sleep and rest. There’s a balance to everything.
Pretty much what I wanted to say. I let fever run during the day, but taking something to help sleep usually makes me feel better than suffering through the night
I had fever last week. I ended up getting high on medication 😅😅... Not fun
Well, for most of the world I'd say - go to the doctor and follow their advice.
Usually, it's the same as the video suggested - if your fever is over ~40C take the anti-fever medication, otherwise don't, but if the fever lasts more than a few hours straight to the point when you cannot rest - contact doctor for further advice.
It's normal and expected to have a bit of a problem with sleeping or rest when sick.
If it's too much probably there is a reason for that which needs to be investigated.
Wharever effected you was likely not "just" common cold (adeno/rhinovirus), there is no way to know now.
You most likely started using the drug when the infection was almost over but the immune system lags behind. Have you done it firsthand, the story could have been very different.
Unfortunately if you are in a country where healthcare is unaffordable (like US), or ineffective (like China) or just does not exists (much of central Africa) you're on your own to judge how to proceed. Each situation is different, and so is treatment.

When I was in my 20s, I had a fever of 41C for about 2 days before I was taken to the hospital. It was so bad I was hallucinating. The dr said that less than 1C higher and I would have started getting brain damage. Later, when I was in the army; I suffered from heat stroke a few times and my body has never been able to regulate my temperature properly since. It really sucks. Imagine not being able to work out, do things you used to enjoy, or even just go outside on warm days without instantly getting sick and throwing up because your body can't tolerate a temperature just a few degrees above normal.
The difference between a fever that someone can just get over and one that can be severe enough to alter your life is so close that it is better safe than sorry and just go to a dr.
to you have the same problem with cold temperatures?
many things can be fixed with specific kinds of therapy, not sure if your problems can fall into that.
I’m so sorry you have to deal with it. I have temp regulation problems due to a genetic thing. I hate summer because of it, and I live in the Southern US. I basically have to stay inside all summer and even going to a doctor’s appointment is really hard; I had a fever for two days after getting out last time.
I also have chronic pain and heat helps, but if I fall asleep with the heating pad on, I wake up with a fever, soaked through, and miserable.
But because of my other health issues I also get fevers just from stress. I had a fever for three months straight before my wedding, during the height of COVID, so I couldn’t get my dress altered for the longest time.
People seem to not get how much it impacts what you do. I don’t even like eating very hot food (especially soups or pasta or mashed potatoes) because I’m hot for like an hour after I eat. It’s ridiculous!
Bro... Anything above 103F and you really should be taking meds. At 41C you should have went to the ER literally right then and there. It's unfortunate that you waited 2 days. I had a fever, when swine flu hit, for a week that was like 103F to 104F and we went to the ER for that shit. 😅
Feel for you there im the same due to having to take immune depressents no protection from anything a cloudy sunny day now feels like the desert sitting in the garden swells my eyes shut due to the pollen actual bubble boy nowadays 😂
I'm questioning my health right now. I rarely get a fever, but I'm easily too hot. I sweat massively and every time I do sport, especially cardio, I'm feeling sick afterwards and get a really bad head ache that can stay for two days. Always wondered what that's all about.
it's incredible to see how complicated the human body is and how we have a solution to nearly. every situation that goes on in it
The magic of the solutions is mitigated by the idea that there were 100 billion of us who have lived and died as trial and error of just our species, and seriously countless others of our progenitors before them. So a fine tuned system makes total sense with virtually any solution to any issue. But the enormous magnitude of "effort" getting us to here is still quite incredible all its own.
There's a video by kurz that tells all possible microbes in life even those that aren't discovered yet to man have an antithesis. In theory, one can survive literally every single pathogen, including the absolute deadliest, provided the immune system knows how to deal with it. The problem lies on the fact that the immune system doesn't have the knowledge on everything. It can create the solution and it has all the tools, it just doesn't know how to do it.
The most incredible part is that immune system can generate almost any antibodies naturally even against the ones that never been infected.
It is so complex. I took 1000mg of Paracetamol in one take (2000mg is max daily usage) and felt better after 90minutes, the odd thing was my temperature stayed the same for next 6 hours (measuring every 1h using analog thermometer)
The other main issue is time... some infections and diseases overwhelm the body quicker than it can activate the counter measure. Its that week, week and a half period where you're body is identifying and making the anti bodies that gets ya... if the invader can do lethal damange to you in that time, then you're screwed, which s why Ebola and the like is so bad... before you're ready to fight back you've taken to much damage to vital organs to survive.

One thing I’ve learned from pharmacy school, is that if you are ever unsure as to whether you should use an anti-pyretic (anti fever) drug such as Tylenol, you can always contact your local pharmacist and they can give you some guidance such as whether it’s ok to stay home and rest vs. should you go to the doctor. They can also advise you on when you should and shouldn’t take Tylenol or other anti-fever medications.
While I am not comfortable going over the guidelines I’ve learned in school here since I have not yet passed my NAPLEX (the USA pharmacy national certification exam) I am comfortable saying that part of a pharmacist’s training involves multiple courses in “self care therapeutics”, which involves steps to identifying what is and is not an immediately refer to doctor type of illness. I wish everyone here to stay happy and healthy and please wish me luck as I continue with my pharmacy training ^^
When is it ever not okay to take something as benign as Tylenol?

I had 39.7c fever that almost knocked me out and wasn’t able to cool down. nurses injected cold electrolytes water in the vein for three consecutive hours, at the temperature your eyes teared, ears humming like there’s a bird inside your head, your shiver doesn’t have feeling at all, but you can see your bed shaking in high frequency like you’re electrocuted. It’s like a daydream that has no ending, time passes slow af.
I experience that every time i have a fever. Its so scary !!!
When I was a kid, I had a really bad 40c fever for a couple of days (maybe longer or shorter, I can’t remember), following a 39.5 fever for a week before then. I’m not sure what it was from, I didn’t get treatment for it but it was some waterborn pathogen, as far as I could guess (there was something being spread by water fountains around the area.)
My foster parents at the time refused to get me to the hospital, so I’m honestly surprised I didn’t get critically ill or anything.
Shit was awful: I was throwing up all the time, dehydrated, I couldn’t move and when I did my body felt so heavy I felt like I was gonna collapse. My eyes burned like hell, my head hurt every time I breathed in, and I was hardly eating too ‘much since I just couldn’t hold it down.
The shakes from that were terrible, I remember not being able to hold much since it was just vibrate out of my hands lmao.
I had my fever temperature at 41.1 Celsius when I was 6
The shaking and weakness are the worst
Your bones feel like over cooked pasta and your muscles like the gelatin to the point that even standing up feels like it is a challenge

@@strgrlszn Oh lol
How adorably you've spoken about our natural science of healing! I stopped taking pills for fever and acute diseases many years ago. Never felt the requirement. 2-3 days of rest and juices is all it takes, and it feels like a deep cleaning of the system. Immunity is stronger.
do you think the succulent chinese meal was a reference to the guy made famous for quoting it,
"What is the charge? Eating a meal? A Succulent Chinese Meal?"

RIP Succulent Chinese Meal guy
Yes, rip Jack Karlson
It totally was!
i was a sickly kid. would have permanent colds and coughs for 7-8 months a year, and only getting better in the summer. i always forgot to take meds and just kept rawdogging my illnesses. i was also a dirty kid too lazy to focus on hygiene. years later, as an adult, i never get sick. a few weeks ago i got my first cold in 4-5 years, and it passed within 2 days without medicine cuz once again, i forgot about them even though i bought them. this made me realize that perhaps relying on meds only means ur immune system loses the opportunity to become stronger. i have friends who regularly get sick, or have random headaches, or something else randomly hurting. i cant remember the last time i had a headache
You are semi right, medicines are best to fix the inmune system doing stupid stuff that is self destructive or to control out of control infections that you can't fight back. Well and vacciness which are like training manuals for your inmune system so it can get strong before even being infected, usually this is good for disseases that leave bad permanent side effects even if your inmune system can eventually defeat the main dissease or for disseases that kill you before your inmune system can fight it back.
Most medicines are symptomatic to make yourself functional by disabling sysmtoms that your inmune system created to fight, this actually makes the illness slightlyt worse but allows you to not have to rest even if you feel like shit longer.
@@diablo.the.cheater yeah i def get vaccines. and one time when i was a kid, i got this SERIOUS illness (idk what its called in english) but its like a flu but on steroids. i was basically puking out green phlegm by the jar-fuls, and was hospitalized, getting injected with an unknown substance regularly. in that case, meds def helped me i think. but for ur average illnesses, like a common cold or a fever, i feel like taking meds only harms u in the long run. unless ur immune system is so weak that u have no choice but to take meds
I think the same, my grandma and mother used to take pills (to combat fever) always and soon I realized they needed more everytime. Something inside my mind told me that wasnt good so I started to take medicine only when I can barely think, refusing theirs offers. Now when I get sick (like amost never) I take 1 pill when feeling TOO bad and get better. I didnt even got COVID or if I got it never realize it was (never feel too bad like my friends told me it was, or lost smells or taste).
The only thing I suffer a lot is bacterial tonsillitis, there was a time I got ill every other month, detected it was when I smoked in outside cold nights. That was like 5 years ago. Remember one time I got 39C fever for like 2 days and cant even open my eyes or think, still didnt take medicine for fever only antibiotics.
Now my girlfriend works with little children so she is ill almost everytime (in winter) and take a pill for almost everything. When she infect me I get one day mildly ill and then restored.
I get people take medicine to keep being functional but I think is bad on the long run. Luckily I have a job where I can say I feel bad and they let you rest for the day without medical license.
no shit lmao, who would have thought hahaha

@@matthewmurdoch6932 Thank you for clarifying. This is why I think this video is wonderful. Many, perhaps most people do not understand the role of fever. When it comes to children, fever is thought to be more important than in adults (and why theirs are higher): they haven't been alive long enough to train their immune system against common pathogens in their environment. The don't even yet have the full array of antibodies (this takes until around age 10). So the body has to rely on the means available. But I also 100% understand with parents who are watching their kid suffer and assume that must be the worst thing, even if it isn't. =/

@@Dr.EdwardClint fever kills many children esp in places like morroco where its already hot and there isn't much AC, it can cause organs to get stuck together and a whole host of other problems leading to the children dying - and the government is so corrupt they will not care and the healthcare so bad, there is no help.

Thanks kurzgesagt for this video because I watched this video 3 weeks ago and now i have fever and understand everything
I dont think most adults are suppressing fever because they feel bad but rather because they need to get back to work and a lot of places dont let you into the office unless your temp is low enough.

The last time I was properly ill, I developed a pretty intense fever. I called out of work, but since I work in a right-to-work-for-nothing state in the US, my work told me I either had to go in, or go to the doctors right then and there.
It was the middle of summer, and feeling lethargic and miserable, I got into my car.
Almost instantly I stopped shivering, felt way more lively, and stopped wishing for my life to end then and there. The inside of the car was boiling hot, usually I start expiring instantly, but I drove all the way to the doctors with the windows up and the AC off, and felt almost like I wasn’t sick. Didn’t sweat a single bead.
I’m not saying this was a good thing to do, I’d much rather have stayed in bed and continued wishing that the world would have the decency to stop existing for a few moments, but it was an interesting phenomenon.
The way my family treats fever is the second it seems you have one you are COVERED in blankets and forced lukewarm liquids not allowed out untill you're better, so normally 1 to 2 days. It is usually a warm heaven but if it's caught early it feels like hell😅 I swear by this method, I think "helping" your body stay warm and retain the heat gets the healing process done in a timely manner
I mean you basically just took a drive in a sauna? Many people appreciate a sauna when they're pretty sick and your experience reminded me of that.
It's your skin shivers that make the fever way worse. If you can keep your body warm enough to reduce stress of your body producing the heat, you can get rid of the shivers and some of the lethargy. Another way I love is to take a near scalding-hot shower for 5 minutes. No shivers, skin pain is gone, headache mostly gone. But, you should definitely lie in bed afterwards because hot water can trigger your body to cool down.
Yeah, just have medical saunas for sick people. It doesn't make sense not to do it. And the sauna place could sign a doctor's note to get you out of work. It seriously is nonsensical that no one in the medical industry has thought of this.
@@gartengeflugel924 huh. I hadn’t thought of it like that. I suppose it is true though. Just without the pore-opening steam.

9:04 "Don't listen to Internet Videos", should've said that 9 mins earlier.
For me, the most unpleasant thing about fever is the fact that sometimes it makes you unable to get some zz’s. Your body temperature will drop naturally whenever you go sleep and yet your body does the exact opposite of it. Very upsetting indeed.
honestly i find it a lot easier to sleep during a fever, if i get to hot i just release the beast from under the covers and fall back to sleep.

I had a food virus last week. Going to the bathroom so many times isn’t great but it helps know that your body is just trying to “detox” itself despite the discomfort. Just kept myself hydrated and well rested till I felt healthy again.
I had covid for the very first time last year. No fever, but my blood pressure and heart rate was sky high, I felt dizzy for a couple months, and I had constant diarrhea. I survived. I caught covid again a few weeks ago, and I had a fever for a couple days, and a mild dry cough for a week. I have no doubt that my body knows how to deal with covid now.
Same. The first time I got covid it was hell. I had an awful fever, lost about half my taste and all my smell, muscle cramps, dizziness, shortness of breath (which was scary cause I have asthma). Whole thing lasted for almost a month. Second time it wasn't that bad at all. Only sick for about 10 days, but everything was much manageable. Never felt so proud of my body kicking butt (also glad for that vaccine, worked wonders).
Thank you. I needed to hear this because my little boy just had a febrile seizure from a fever and I'm a PTSD mess right now. Knowing the fever has a purpose helps so much
But do remember that if the fever exceeds 41 C, then it is urgent to reduce it with meds.

@@Sketchblopp Nah I'll listen to the voices instead.
@@DamonTorroExceeds 39. If it 39 it's better to suppress it.
I must admit that it never occurred to me that fever wasn't just a symptom of being sick, but one of the ways your body actively fights the illness.
Most of the feel bad symptoms are your body actively waging ear against the infection. From sinuses swelling to slow down invaders, mucus to trap them, stomach being purged in either direction to flush them out. Not pleasant and can absolutely get out of hand and always consult your doctor but that's the origin of it
This is like very basic knowledge of fever.
@@tioswift3676 Then I must be stupid! But I think there's a lot of people who thought as I did, which would seem to be an argument against it being "basic" knowledge. Basic for medical students, maybe. Not so basic for most people. You should feel very smart!

There is a bit of an issue in this video, (*sorry I hate to be that guy I know you all work really hard to research this topic*), and don't get me wrong I love a good evolution-defying system, is that while Fever IS difficult to adapt to, it's not even marginally difficult enough to justify why Fever is so ubiquitously effective in nature.
Some context for this; Microorganisms evolve orders of magnitude faster than we do, and the evolutionary arms race between those who adapt for high temperatures or low temperatures does exist of course, but that explains only the statistical likelyhood of being infected by fever-resistant bacteria.
But if you noticed, we almost never encounter fever-resistance in bacteria, which doesn't make sense unfortunately for the theory, because the expected result should be rarer instances of slower-spreading viral infections who are fever-resistant.
That's not to say that the theory posed in this video isn't widely accepted, it is, but that doesn't make it correct.
An extremely important context-clue that should indicate why this theory is fundamentally flawed is stated earlier in this video.
As you mentioned, there are many microorganisms that can adapt and even thrive in much, much higher temperatures than we could EVER produce inside of our bodies.
Another, and even more troubling consideration for this theory, and in the same slide as the previous one; These microorganisms have demonstrated that they can adapt, do adapt, and can even thrive in very wide temperature ranges, including the entire temperature range that our bodies are capable of.
So, you might be asking, why is high fever-resistance such an unusual adaptation?
Here in lies the part that you guys missed in the video, its not about the adaptations nearly as much as it is about the thermodynamics of microscopic life.
Let me explain, the vast majority of evolutionary adaptations change the proteins that the organism will produce in a given set of circumstances, it is absolutely essential to all organisms to produce proteins that are suitable to their environment, not only so that protein itself can function, but to restructure the non-protein systems appropriately when the environment changes.
All biological systems (proteins, receptors, signaling molecules, DNA, membranes, etc.) function under an optimal temperature, and going outside this temperature can quickly cause systems to slow down, fail, or even disintegrate, which is why most cells have redundent systems AND can ensure Homeostasis by quickly producing a new, or altering an existing system when they detect a change in conditions.
But to do so, they essentially out-mode the entire system that existed before the change, while having to produce a new one, and this is a very energetically expensive process for the organism.
Multiply that process by the number of failing systems and you can see why microorganisms get "Stressed" by the heat changes in a fever, particularly because microorganisms are so competitive that they prioritize optimal conditions and NOT rapid-adaptability.
This also answers why our temperatures only have to change a few degrees, the AMOUNT of heat change is relevant only to the extent that Microorganisms "optimal" conditions are violated, forcing them to invest resources in producing new systems, we can't actually exceed the RANGE they could adapt too, and we don't have too, we only have to change it JUST enough to force them out of their comfort zone.
It all circles back to thermodynamics; the problem is not ADAPTATION as much as it is ECONOMY.
As said in the video, our bodies have vast energy stores that can be exploited to drastically raise the temperature of our bodies, but ALSO have lots of energy reserves so that OUR cells can create all the molecules and new proteins necessary to adapt to the new, very hot environment.
This is NOT the case for our parasitic guests, Microorganisms have a very limited resource pool, even IF they were already adapted to be capable of changing into a more heat-compatible form, they still need to expend resources, resources they don't have, to USE those adaptations.
Here lies the reason that Fever can be such a small shift in conditions and is still so universally effective.
It is simply a one-sided battle of SIZE, a game of attrition that the tiny microorganisms CAN'T win unless they can kill us and eat us faster than they die.
Our bodies enter energy-starvation the moment fever hits, it becomes a battleground with our cells over the resources that both they and our cells need to adapt and survive.
Additionally, the parasites must not only survive but also reproduce very quickly in order to not be wiped out by our immune system, so as stated in the video, they have to reproduce, kill us, and adapt at the same time.
One important part of this is that fever fluctuates throughout the day you're sick, going from very hot to almost normal body temperture, and this causes the invaders to constantly have to sink more resources into this process than just changing once.
To conclude; Microorganisms cannot overcome Fever, and it is not primarily due to competitive evolutionary pressure as stated in the video. Fever is not really about defying Microorgansism's ability to adapt, its actually attrition warfare, the Microorgansisms are Napolean and your body is 1812 Russia.
This is such a thorough and well written comment. Well done!
Congrats to you if you read that whole thing,
I just read the conclusion
Satisfying to read
Great closing line.
I think the video explains it pretty well. Bacteria that adapt to resist fever don’t function as well in a healthy person. It’s a classic stabilizing selective force where they stay in a specific range because adapting in either direction is a disadvantage.
From a doctor's perspective: always take your fever medicine as prescribed if prescribed on time.
Certain fever medication in combination with antibiotics can also reduce inflammation. Reducing inflammation early on can help reduce damage and recovery period. It might be a good idea to rest anyway and stay warm when on fever medications. Inflammation early treatment can reduce recovery to 3 days/immediately for something that could have been 10 days, a month, or chronic/permanent.
agreed. Generally speaking viruses will rarely shoot up above 39-40C and are probably the best bugs to maintain a fever for especially if it doesn't interfere with sleep. Bacterial infections are more amenable to antipyretics because of the link to inflammation which helps with the delivery of your antibiotic and reduces the chance of cytokine storms. In that case controlling the fever outweighs the downsides (bacteria are also less affected by fever).
Fever that doesn't go down with antipyretics (or lasts more than 3-5 days) is also likely to involve a more serious infection and needs to be kept on top of as it could shift towards mengitis, septicaemia, pneumonia etc. The reverse is also true it may be the case that you have no fever but still have a very serious infection so it's not a golden rule...always ask your dr/second opinions for decisions involving health.
Nuh uh
Kinda agree with you and Damn so confused! Should we take fever medication or not? Is it net beneficial to take fever medication with slightly weekend immune system or not take and have better Immunity?
@@VaibhavSharma-uu1om Think of fever like an optimisation for a "normal" immune system to gain additional benefits...
However, there is no general advice for an abnormal immune system, because the effects will be different depending on the abnormality.
For example a hyperactive immune system can benefit from antipyretics, but a hypoactive/senescent immune system may benefit more from fever.
It all depends on the exact root cause and your status etc. It's why you need a dr to make this decision for you.
