YOUR BRAIN ON COFFEE Love coffee? We all need an energy boost at times, but how exactly is caffeine affecting your BRAIN? And could too much kill you? Find out in our latest video! ua-cam.com/video/4YOwEqGykDM/v-deo.html
"Is this a dare?... because, my brain and me- we have an understanding. Though, from the sound of things my stomach is the 'Lite Weight' in this particular fight. Shape up, Stomach!"
I stayed up all night and i started to feel very sleepy till i drank 2 cups of coffee (no sugar or cream) and then like around 30 min later I feel alerted and now ready to take on school
AYGEE214 lol the first time I had coffee (about under 2 week ago) i fell asleep half hour after drinking... it was mid day and I got full nights of rest and I never take naps. I'm naturally a hyper person so avoided caffeine and always made sure my pop was caffine free because I thought it make me bounce off the walls lol. I've had monster drinks months ago (first time I had a monster I went to bed about 2 hours later) and just made me feel relaxed. I've had caffine about 5 times in my life (1 icecap which had no effect, a sip of someones french vinilla coffee once, 2 monster on diffrent days of course, and half of my brothers monster one time) before I started drinking coffee recently. i decided to drink coffee because I like how it makes me feel relaxed... I took a break from it over the weekend that just passed and man was I hyper those 3 days I was literally running around my house doing laps because of how much energy I had and staying up till 1am pacing the basement because I just had soo much energy. haha I drink coffee to chill myself out. also I drink water after drinking coffee to stay hydrated.
Fun facts on coffee. I'm glad I can't od on coffee. 70 cups at one time would be a challenge. I love the stuff. My father drinks 5-6 cups a day ,and he is a very healthy 84 year old.
I tend to drink 12 cups of coffee when I go all nighter of doing college homework and study that does not give me time to sleep, but from time i tend to worry if I'm gonna die from too much coffee
Everytime I drink coffee I get extremely hyper but then when the effect passes I feel extremely weak, shaky and light headed, is that normal? Does it happen to anyone else?
happens to me too sometimes,this is caused by fatigued adrenaline receptors. What i do when this happens is to slightly lower the dose the next time - or ,to stop drinking when i get this "tired" symptom
I don't like it or milk by itself. The only time I drink either is when I'm putting them together to make cafe con leche (coffee with milk). Then I add some sugar and it's fine. You can try that if you really want to try and drink coffee, but if not then it's no big deal.
YingofDarkness I basically like any drink that's... how do I call it, light? I don't like coffee, alcohol or carbonated drinks. I let carbonated drinks sit open in the fridge to get rid of that damn burn that I hate. I like tea, juice, milk etc.
***** right after you drink a fresh cup of coffee, listen to your favorite songs on your headphones or play some videogames... you will feel the buzz ;) it's not like the alcohol buzz... The coffee buzz seems to "amplify" the buzz you already have with something, pretty interesting... I was not aware of this adenosine shit, I tried to quit many times, I don't know anymore if coffee is good for me anymore because is too much crash for too little buzz :(
+PluriiGaming coffee makes you more alert of what you are doing, you feel less tired or drowsy. Even your eyes widen up a bit. I am not addicted to coffee, but I know I need it when I am working or studying. I am a lazy person. I don't really care about coffee on weekends. But coffee is like a fuel that keeps my goings on work-days. As far as taste is concerned, I hated the taste when I was a kid. It used to feel 'bitter' and 'putrid' in my mouth. But hell, now I love it. In my case, it is more like an acquired taste.
I remember going to a friends house one night after work, and his brother and I were really into coke heavy at the time and I had drank the large cans of redbull before going into work, I made the mistake of doing about a gram and a half with them and we stayed up all night playing super smash bros melee till 5 a.m. and I was pacing back and forth around his living room because it felt like my heart was about to come out of my asshole. Needless to say I never touched a redbull again
AsapSCIENCE coming through again with the science knowledge! I have a paper due on the psychopharmacological properties and effects of caffeine and you guys make it so easy to understand! Thanks Guys!!
Same, every time I have drank coffee (or any caffeine drink) I have not experienced any changes in tiredness. Maybe I need to drink more? 1 cup should be enough to take an effect, right?
You tell me. What is going through your mind when you see something beautiful? What are you feeling? Is it overwhelming? Is it taking you away to a dream-like place? Do you cry because reality is often so unpleasant that the contrast between it and such beauty invokes strong feelings? The question "why do we cry" is invalid as it only applies to a portion of the population, but that is only a matter of technicality.
Caffeine is fine, I have never really felt too addicted to it. I have no addiction to alcohol. But NICOTINE. THAT is HARD to quit. I'm trying. I was completely straight edge for 5 days. I just started drinking coffee to combat the foggy effects from the nicotine withdrawals. It's been WAY harder to quit than I thought, but I'm hanging in there.
I was having too much coffee during work from home.i started taking caffeine pills when my tolerance grew.but stimulants damage our digestive process in long run.Hence i started taking biochemic tissue salt Kali Phos 6x.the result is phenomenal.i dont need to drink coffee anymore.my mental focus and concentration during work from home has gone up tremendously.
You should do a video on energy drinks, and what are the side effects. I know most of them but they are very interesting. I am just suggesting because people might stop drinking so much.
Does the eye color affect ones vision? Example: Does everyone see "blue" the same?? Relating to vision, why do we see white flashes sometimes that impairs our vision? ??
I can say this: It's not the color of eyes. It's the size. Near sighted people have larger eye length, and Far sighted people have smaller eye length. I wish Daddy could give me contacts soon.
@Kirby Popstar : I don't mean the degree of vision, I am enquiring about: does the vision of colour differs with people of different eye colour. I read somewhere before that dark eye colours see in the dark better than those light eyed. I wonder why that happens
Thanks for this video! Research shows that coffee can help with mental alertness, type 2 diabetes, weight loss, Parkinon’s, prevention of cardiovascular disease, and may prevent gallbladder disease!
Time won't stop because its a dimension through which we exist. Thats like asking if everything just became 2D. As far as water slicing through rock, you can say the grand canyon is an example of that so yea but not necessarily like a blade would
Firsticous Lastilicous How is having knowledge in any way sad? It would be sadder if you didn't know any of them, but then you could learn them and be happy :)
Our brain freezes because the blood that goes up to our brains passes through the top of our mouths, so when we eat a bunch of ice cream or ice water, etc, it cools the blood down and when it gets to your brain, it's all cold.
There's a gene that has an influence on it, yes. Meaning if you carry it, you have a higher chance of ending as an alcoholic. It'll rise your dependency (in a nutshell)
sugar is known to be addictive and excites the brain similarly to cocaine, so you should do a video about your brain on sugar! that'd be very interesting.. thanks for the videos!
I love coffee but it would always affect my sleep or make me crash in the middle of the day. I tried this nootropic coffee from Krios coffee and I no longer have issues because it has this amino acid in it that is in green tea. Its delicious and gives a more calm and natural energy. I wish I could give up caffeine but I love it lol
@@TheEarBreaker don't you mean downregulated? Since drinking coffee in the long term will increase the number of adenosine receptors and when you quit coffee, the adenosine receptor gene gets downregulated to restore balance?
Rene Wu I would personally rather not depend on it.. I have never liked coffee (and any hot liquid) and as the video explained, people who don't drink coffee won't be as in need of coffee or as sleepy without it.
The first time I had a good mug of the black stuff I felt like I would never have to sleep again, but after awhile I had to quit for a few months for the caffeine to start working again.
Coffee is more than caffeine, which cause additional effects or enhance the effects of caffeine. Notably B-Carbolines, which acts as an MAOI, and terpenes which can affect blood brain barrier permeability. Caffeine by itself feels different than Coffee. The same reason Tobacco is different than nicotine
is it possible for someone to be immune to caffeine? I drink coffee every morning, but only because its a habit... it does absolutely nothing for my awareness or my sense of being tired.. im just as tired and aware as i was before i took the coffee, and its not even that i dont notice it, cuz sometimes i pay special attention to it, just to see if it had any effect on me, but no... after 10 mins, nothing changes, after 1 hour, nothing happens (apart from a natural way of waking up and getting more aware...
Lana Waters yea, i thought about that, but i only drink coffee for the past year, because i never needed it before that.. i gave it a shot, so that i can easier wake up, but even at the start i noticed nothing.... i thought if i just keep doing it i will start feeling it's effects, but it never happened... by now its more of just a habit :/ so my question still stands, is it possible to be immune to coffeine? or if not immune, than resistant to it enough so that whatever effects it has on u is so negligible that u dont notice it?
Unknown it might depend on the type of coffee you drink. Light roasts contain more caffeine for example. Also, coffee can be more effective if you drink it in the late morning as opposed to when you wake up. I have a high tolerance for caffeine but that's because I consume a lot of it (5 cups and a few red bulls). Try drinking a few glasses of water before your coffee in the morning. You feel tired because you haven't had water for a few hours.
Go about 10-20 days with NO caffeine at all, and they will fade. When you drink caffeine again it will have a similar affect as it would as you first started drinking coffee, however you will rebuild a tolerance quicker. try to take these brakes once every other month so you don't take irregularly high amounts of caffeine, and so caffeine keeps its energetic affects.
Hi Dave, I've discovered a way to get rid of dependence on caffeine and feel more alert, awake and less fatigued. Apparently caffeine causes the release of _histamine_ which triggers the _H3 receptor_ in the CNS. So the problem ain't _adenosine_ per se. It's more to do with the _glutamate-glutamine cycle._ I fixed it taking a tea spoon of _l-glutamine_ (the precursor to l-glutamate) in a bit of milk twice daily. I'll post a longer comment with more info.
O. Rood I used to take L-glutamine pills once in a while (muscle rebuilding purposes). Now I eat the L-glutamine gummies from GNC. But I had never heard that they could help to feel more awake. It'd be nice it if did. Let me know it goes!
Hi Dave, that's interesting. Muscle _rebuilding_ purposes .. or muscle _building_ purposes ? *It worked for me and for others who were fatigued and drink a lot of coffee to compensate.* The chemical structure of glutamine is very similar to a neurotransmitter which is required to be alert, awake so that's no surprise.. especially if I'm correct that long-term caffeine consumption ends up exhausting the available supply of said neurotransmitter and/or its precursor l-glutamine in the CNS. What's surprising is that of the layman info I read online most is contradictory or just plain wrong. I mean.. _it's one of the most abundant amino-acids in the body_ (even if it is locked away in muscle tissue or other cells) so saying it is a 'poison' (as some websites claim) makes no sense. However.. everything in moderation. It can be readily metabolized by cancer cells so.. yeah, I wouldn't recommend it to people who suffer from that ailment. I'd be more concerned about someone suffering a placebo response after reading some of the strange ideas on the web regarding glutamine. Average absorption of tablets is usually not 100% or even 50% depending on the ingredient.. so I took a tea-spoon of l-glutamine _powder_ in a small bit of milk. According to GNC (which you mentioned above) they say: _"By micronizing large molecules into smaller particles that are easier to absorb"_ .. it will make a "better" product. ...Treating a fine-powder of a _reactive_ soluble amino-acid in some kind of chemical cocktail to change its 'size' sounds a bit OTT and would by definition attempt to _break down_ its molecular structure to "micronize" it. I would be extremely sceptical about any 'treated' or 'concentrated' l-glutamine supplements. Also they charge $20 for 60 of their RapidDrive® Performance® gummies.. at 306g per pack that's 5g per gummie. I paid around $6 for 500g of powder and took a rounded teaspoon which'd be a little less in weight, except the powder wouldn't have all the extra ingredients that your gummie has.. sweetener/sugar etc so it probably would be more equal than not. So if you didn't notice any effect from this RapidDrive® Performance® version I'll probably avoid any "micronized" or "treated" l-glutamine in the future and stick with what I know works. However if you're into fitness and body building then you probably wouldn't have any issues with chronic fatigue anyway so the point is moot.
Also.. knocking back 100ml of milk with a teaspoon of equal weight to one of those gummies would deliver a higher amount to the blood stream than sucking on a gummie for half an hour. (If that "micronized" form actually does anything and hasn't broken down completely this may explain the difference.) The blood has quite a considerable amount of available glutamine (in different metabolized forms) .. and it _can_ pass the blood-brain-barrier, so perhaps it is the quick boost that helped deliver it to the CNS in my case. The only other thing that springs to mind is that it exists in a stable form by binding to another metal or 'salt' and that the micronized form bound to some other molecule which inhibited its ability to cross the blood-brain-barrier easily. I'm not an expert nor a chemist so I can only speculate. (And if UA-cam didn't show my previous comment, I hate them.)
Caffeine is not a dopamine reuptake inhibitor and comparing it to cocaine is BS. You also forgot to mention the MAIN effect of caffeine - AChE inhibition with IC50 7.25microM while for adenosine recpetors (A2A) it's at least 9microM (most studies have higher numbers). So, caffeine is not just what you think. :)
Problems with your comment: 1) The majority of the world uses the metric system, so even if he was American, it would make just as much sense for him to use it. 2) It's a science channel and the scientific community uses the Metric system 3) He's Canadian... I am American, the Metric system makes more sense, and I wouldn't mind if we started using it. The FPS system is great, but the numbers are so random... Why is 5280 ft 1 mile? It's just such a random number...
They do when they're no longer in use. So if you constantly keep your energy up by other means (physical activity or whatever) they won't go away as fast. The brain is constantly changing and allocates energy to make stuff it needs more.
+google sucks coffee doesn't work on me. makes me calm and sleepy. I'll only ever drink if tired. Rockstar energy tried it. just gave me a dehydration headache. that's all. I have caffeine rarely.
2:33 Logic? You get tired when the caffeine leaves your system late day-time, so you drink more. When going to bed, you don't want caffeine sticking around in your body.
This video is very misleading and half-done. They don't even mention that there is more than one type of adenosine receptor affected by caffeine, and that there are studies suggesting that one of these receptors doesn't produce tolerance. One receptor is linked more to the performance-enhancing effects that go away, the other potentially allows caffeine to keep you up at night despite your caffeine tolerance.
Of course dude, the dopamine release process in the brain it´s pretty similiar to that ones that´re caused by stimulants drugs like amphetamines or cocaine.
I think it depends on the person. I drink coffee at work to stay alert, but I don't even think about it on my days off. However, there are people at work who admit they are addicted to caffeine.
It is a mildly to moderately addictive substance (depending on the person). But the people comparing it to the addiction of meth are insane. I drink it every weekday morning to get up for school, but can easily go without with little negative effect other than being slower to shake off the morning grogginess and an increased chance of a migraine (I got migraines long before I started drinking coffee, and when I started my migraines sharply reduced, so this is to be expected.) I went almost the entire summer 2 years ago without coffee and was just fine (I never had to wake up early, so I didn't need it.) As long as you avoid excess (I recommend keeping it to about 16 oz a day) your fine.
Yes, but I'd say it's only mildly addictive. Pretty much the only thing you may experience as withdrawal symptoms is getting a light headache and feeling tired in the middle of the day. If you enjoy the taste you might crave for it in line with other food/drinks. Keep in mind it can interfere with sleep if you dont avoid it for several hours before bedtime (you should avoid it minimum 5 hours before bedtime is what I've read), and when you don't get enough sleep, you may compensate by drinking more coffee.
how did you quit? i am heavily addicted and tried everything, but cant seem to stop. Im in twelve step recovery for drugs and alocohol addiction too. But caffeine is the only thing im still doing and its totally messing me up. im hypersensitive to it. Do you think you can message me?
With its stimulating effects, it’s easy to understand why coffee is the second most traded commodity on earth after oil. For many, it keeps us awake and moving through our busy days. But how does it work? What exactly does coffee do to your brain? 2- Whenever you’re awake, a chemical called adenosine slowly accumulates in your brain and this adenosine binds to receptors which slow down brain activity. Ultimately, the more adenosine there is, the more tired your brain feels. Which makes sense as the longer you’re awake, the more fatigued you become. Conversely, while you sleep, the concentration of adenosine declines, gradually promoting wakefulness. 3 - But it turns out that the caffeine in your coffee is incredibly similar to adenosine in structure. The caffeine works its way through your bloodstream and into your brain where it starts to compete and combines with adenosine receptors. But because it’s not adenosine, the sleepiness effect isn’t felt. Adenosine can no longer bind, meaning its calming properties are diminished. Which is great for you when you’re feeling tired. 4 - However, with long term use of caffeine, your brain responds by creating more adenosine receptors, which means more caffeine is required to elicit the same response. It also means that when you try to quit drinking coffee or miss your daily intake, you might experience some withdrawal symptoms and feel more tired than you would have before you ever drank coffee. But the caffeine doesn’t stop there. 5 - It also stimulates the production of adrenaline - you know, the fight or flight hormone. This increases your heart rate, gets your blood pumping and even opens up your airways. Furthermore, it affects dopamine levels by preventing its reabsorption in the brain, which makes you feel happy. In fact, this is the exact same thing that cocaine does, just to a lesser degree. It’s a drug after all. 6 - This dopamine stimulation is also the aspect of coffee that makes it moderately addictive. So, can you drink too much coffee? It turns out there is a lethal dose of caffeine, which is somewhere around 150 milligrams of caffeine per kilogram of your body. This means if you weigh 70 kilograms, you require 14,000 milligrams of caffeine to overdose. 7 - Put into perspective, an average cup of coffee contains roughly 150 milligrams of caffeine. Meaning if you’re 70 kilograms, approximately 70 cups of coffee would kill you. However, you would have to drink those cups all at once, making it effectively impossible to overdose on caffeine from coffee, since you wouldn’t be able to physically fit that much in your stomach. 8 - You would also start experiencing mania and hallucinations before getting to this point. Caffeine also has a half-life of around 6 hours. So, if you drank a standard coffee with around 150 milligrams of caffeine, after about six hours, there would only be around 75 milligrams left in your system and you’ll be feeling half of the effect. 9 - And 6 hours after that, you’ll have 37.5 milligrams, leaving more room for adenosine to jump back into action, which is why you may reach for another cup throughout the day to remain that glorious alert and energetic feeling. So, drink up and enjoy the buzz while it lasts. 10 - And for all of you who are in school, while we know that caffeine is key, so are good deals on textbooks. So, we’ve teamed up with slugbooks.com to get you the cheapest prices for the books you need. All you have to do is head to 10 - slugbooks.com/asapSCIENCE and search the ISBN number of the books you’re looking for. SlugBooks will then compare prices from all across the net. 11 - Seriously, we know how expensive textbooks can be so hopefully this will save you some money.

Apparently, my mother drank coffee while she was pregnant with me, The opposite with my sister, I would bet that's the reason why my sister can't sleep drinking soda after 2pm, While I'm on my 5th cup of coffee.
Pretty easy to answer for yourself, try it. I don't mean try having intercourse with someone of the same gender, but see if you can flip which gender you find attractive just by choice.
YamiYami17 Wow, everything you said basically shows you rhave zero information about actual gay people and you've learned everything you know from an equally clueless and likely antigay community. Good job.
***** A guy in my office be ordering 2 large cups, first thing in the morning (for years) ...l mean like 2 large cups at a time...then wonder why he in pain every time he takes a step or get up from his desk.
quoting from wiki: "Dating to the 1970s, coffee has been incorrectly described by many, including historian Mark Pendergrast, as the world's "second most legally traded commodity".[138][139] Instead, "coffee was the second most valuable commodity exported by developing countries," from 1970 to circa 2000"
no, caffeine gives you energy including coffee energy even though it makes you sleepy it's still wakes you up makes you pee alot through the day for 12 hours
If I don't have coffee my memory is foggy, I have issues with brain function and focus, and begin to feel like a machine, if I don't have coffee at that point I begin to experience a crusing fatigue and feel hopeless
4 cups of coffee, if each contains 150mg of caffeine, can affect you much like a low dose of an amphetamine. Just for your information :D Though, i have been drinking for so long i would probably drink 10 cups to get the same feeling as when i first started. Goddamn.
shaul rosenberg Oh yeah, i've heard that helps :D But, i am waiting for some good moment to stop it, right now im busy and need that caffeine, as stopping can cause headaches etc... D:
Ekinlabberer Yeeah. gotta try sometime :D I am only 14 and still been drinking for 4 years about 2 cups/day, sometimes less or more. Soooo it is going to be a challenge for sure :)
Just quit for a time. I quit for 6 months and now even 100mg og caffeine gives me insane energy. I don't drink every day and it's worth mentioning i am very sensetive to Caffeine.
I thought that drinking coffee created a placebo effect in the people who drank it, and that’s why they felt more awake. After all, drinking a cup of coffee does nothing for me. So, one night, I needed to do lots of school work and I was tired and I decided, “If one cup of coffee doesn’t work, why not drink several?” I don’t know how many tablespoons of coffee I put in my cup, but it was a lot. I put loads of sugar in too, and the whole thing tasted like crap, but I needed the energy, god dammit. I certainly got that energy! I was shaking all over, my skin was flushed red and white, I couldn’t feel my legs, my heart was pounding out of me and I had terrible anxiety. Learned my lesson. Will never do that again 😂
Caffeine didn't have any effect on me for years but ever since I started restricting my food intake(due to my disorder)every time I drink coffee I can't sleep for days:/
I try to treat caffine the same way I treat alcohol. Even though the effects are wildly different, I want to enjoy it now and then without being dependent on it.
all coffee does is make me poop
+skylaer mcgovern same here.
true
it makes me tired ;-;
+skylaer mcgovern You have to make it strong and have a whole cup
When I'm stoned, I drink coffee. Don't change anything on the experience, it's just like when you're earlier smokin' in the day

It would be interesting to do a video on our brain on TEA! Just to see and compare with coffee :)
I just hate coffee
I drink coffee every day because I love the taste. But I've never felt more awake or less awake by it. Weird!
I stayed up all night and i started to feel very sleepy till i drank 2 cups of coffee (no sugar or cream) and then like around 30 min later I feel alerted and now ready to take on school
Kristina Sandnes Lets take the test. Stop drinking coffee for a whole week and let me know if you feel more or less awake. Lol
AYGEE214 lol the first time I had coffee (about under 2 week ago) i fell asleep half hour after drinking... it was mid day and I got full nights of rest and I never take naps. I'm naturally a hyper person so avoided caffeine and always made sure my pop was caffine free because I thought it make me bounce off the walls lol.
I've had monster drinks months ago (first time I had a monster I went to bed about 2 hours later) and just made me feel relaxed. I've had caffine about 5 times in my life (1 icecap which had no effect, a sip of someones french vinilla coffee once, 2 monster on diffrent days of course, and half of my brothers monster one time) before I started drinking coffee recently. i decided to drink coffee because I like how it makes me feel relaxed... I took a break from it over the weekend that just passed and man was I hyper those 3 days I was literally running around my house doing laps because of how much energy I had and staying up till 1am pacing the basement because I just had soo much energy. haha I drink coffee to chill myself out.
also I drink water after drinking coffee to stay hydrated.
wait you never feel less awake by coffee?? that is weird!
try caffeine pills for getting that awake feeling
Fun facts on coffee. I'm glad I can't od on coffee. 70 cups at one time would be a challenge. I love the stuff. My father drinks 5-6 cups a day ,and he is a very healthy 84 year old.
I tend to drink 12 cups of coffee when I go all nighter of doing college homework and study that does not give me time to sleep, but from time i tend to worry if I'm gonna die from too much coffee
Everytime I drink coffee I get extremely hyper but then when the effect passes I feel extremely weak, shaky and light headed, is that normal? Does it happen to anyone else?
yes it does.. it depends on sensitivity.. some people are more sensitive some people are not.
thats literally a caffeine crash xDD it happens to me too, i enjoy the highs and lows tbh
How do you take your coffee

idk about you guys but when i drink coffee... it makes me even more tired
happens to me too sometimes,this is caused by fatigued adrenaline receptors. What i do when this happens is to slightly lower the dose the next time - or ,to stop drinking when i get this "tired" symptom
Same here...
So what I learned from this video is that coffee is basically a drug. And I guess I'm a drug addict then.
It is a drug. Not "basically a drug".
Yup. I'm an addict too.
So is sugar.
rallaa
No, a drug has to change a chemical balance in the brain. As far as I know, sugar is little more than a sweetener.
Coffee isn't a drug. Caffeine is
i use to drink coffee everyday and quitting it got me tired, now i barely drink it
I've never understood the appeal of coffee. It doesn't even taste good.
A lot of people like it, though. How do you feel about mate?
Nick Nirus I know and I don't understand why it's so liked. It's just not a pleasant taste imo.
I don't like it or milk by itself. The only time I drink either is when I'm putting them together to make cafe con leche (coffee with milk). Then I add some sugar and it's fine. You can try that if you really want to try and drink coffee, but if not then it's no big deal.
It does if you put 1/4 of a cup coffee and hot water, add three teaspoons of sugar and fill the rest with milk. Then it's sweet.
YingofDarkness I basically like any drink that's... how do I call it, light? I don't like coffee, alcohol or carbonated drinks. I let carbonated drinks sit open in the fridge to get rid of that damn burn that I hate. I like tea, juice, milk etc.
coffee crashes me in 2 hours 😭
i crash in 45 mins with no sugar just milk and coffee and i have around 10 mins of the normal feeling so i can relate HARRRD
Same here
ADHD!!!
That's why I try to rely on food when I'm drained and coffee too.
Below...
My rules of coffee. Never drink it if i'm going outside
Otherwise i'll keep wanting to pee and its troublesome
Omg same. It's the only problem I've had with coffee (and tea, to some extent). The constant need to pee
I’m an alpha male so I just whip out my peen and piss in the grass

tell that to Fry, he had 100 cups
Not all at once though
yeah and he also started to hallucinate, so i guess it wasn't too far off the mark.
I was thinking about that too. But he became Flash
Nikki DeRaad I think that was from his lack of sleep rather than drinking coffee. He didn't sleep till the very end of the episode.
I don't think you can compare Fry to Godot (from Ace Attorney). I mean, Godot drinks coffee like it's water.

Are you guys addicted to coffee because it tastes good or because it gets you awake? I'm only addicted to it because it tastes good! :D
***** right after you drink a fresh cup of coffee, listen to your favorite songs on your headphones or play some videogames... you will feel the buzz ;) it's not like the alcohol buzz... The coffee buzz seems to "amplify" the buzz you already have with something, pretty interesting... I was not aware of this adenosine shit, I tried to quit many times, I don't know anymore if coffee is good for me anymore because is too much crash for too little buzz :(
+PluriiGaming coffee makes you more alert of what you are doing, you feel less tired or drowsy. Even your eyes widen up a bit. I am not addicted to coffee, but I know I need it when I am working or studying. I am a lazy person. I don't really care about coffee on weekends. But coffee is like a fuel that keeps my goings on work-days. As far as taste is concerned, I hated the taste when I was a kid. It used to feel 'bitter' and 'putrid' in my mouth. But hell, now I love it. In my case, it is more like an acquired taste.

I remember going to a friends house one night after work, and his brother and I were really into coke heavy at the time and I had drank the large cans of redbull before going into work, I made the mistake of doing about a gram and a half with them and we stayed up all night playing super smash bros melee till 5 a.m. and I was pacing back and forth around his living room because it felt like my heart was about to come out of my asshole. Needless to say I never touched a redbull again

Why do we cry when we see something beautiful?
because SCIENCE
Do people cry when something is beautiful?
I only cry when I'm anguished or really really furious (and, sometimes, when I'm scared).
You tell me. What is going through your mind when you see something beautiful? What are you feeling? Is it overwhelming? Is it taking you away to a dream-like place? Do you cry because reality is often so unpleasant that the contrast between it and such beauty invokes strong feelings?
The question "why do we cry" is invalid as it only applies to a portion of the population, but that is only a matter of technicality.
I've never cried because I saw something beautifull or because I was happy. I only cry If i'm really furious or if i'm really really scared
Caffeine is fine, I have never really felt too addicted to it. I have no addiction to alcohol. But NICOTINE. THAT is HARD to quit. I'm trying. I was completely straight edge for 5 days.

Does the eye color affect ones vision? Example: Does everyone see "blue" the same?? Relating to vision, why do we see white flashes sometimes that impairs our vision? ??
I can say this: It's not the color of eyes. It's the size.
Near sighted people have larger eye length, and Far sighted people have smaller eye length.
I wish Daddy could give me contacts soon.
@Kirby Popstar : I don't mean the degree of vision, I am enquiring about: does the vision of colour differs with people of different eye colour. I read somewhere before that dark eye colours see in the dark better than those light eyed. I wonder why that happens
That's a lie. ^

If you stop drinking coffee, will the number of adenosine receptors decrease?
It takes up to 9 days for caffeine tolerance to drop and adenosine receptors to be upregulated, thats when you become more sensitive to caffeine.
@@TheEarBreaker can i have the source to this info, i really want to know everything about caffeine lol
@@TheEarBreaker don't you mean downregulated? Since drinking coffee in the long term will increase the number of adenosine receptors and when you quit coffee, the adenosine receptor gene gets downregulated to restore balance?

The first time I had a good mug of the black stuff I felt like I would never have to sleep again, but after awhile I had to quit for a few months for the caffeine to start working again.
Coffee is more than caffeine, which cause additional effects or enhance the effects of caffeine. Notably B-Carbolines, which acts as an MAOI, and terpenes which can affect blood brain barrier permeability. Caffeine by itself feels different than Coffee. The same reason Tobacco is different than nicotine

is it possible for someone to be immune to caffeine? I drink coffee every morning, but only because its a habit... it does absolutely nothing for my awareness or my sense of being tired.. im just as tired and aware as i was before i took the coffee, and its not even that i dont notice it, cuz sometimes i pay special attention to it, just to see if it had any effect on me, but no... after 10 mins, nothing changes, after 1 hour, nothing happens (apart from a natural way of waking up and getting more aware...
As it mentions in the video, the longer you drink coffee, the more you need to drink to feel the effect. Which is the same with any drug.
Lana Waters yea, i thought about that, but i only drink coffee for the past year, because i never needed it before that.. i gave it a shot, so that i can easier wake up, but even at the start i noticed nothing.... i thought if i just keep doing it i will start feeling it's effects, but it never happened... by now its more of just a habit :/ so my question still stands, is it possible to be immune to coffeine? or if not immune, than resistant to it enough so that whatever effects it has on u is so negligible that u dont notice it?
Unknown it might depend on the type of coffee you drink. Light roasts contain more caffeine for example. Also, coffee can be more effective if you drink it in the late morning as opposed to when you wake up. I have a high tolerance for caffeine but that's because I consume a lot of it (5 cups and a few red bulls). Try drinking a few glasses of water before your coffee in the morning. You feel tired because you haven't had water for a few hours.
Lana Waters
well, i drink Tchibo, the proper type u have to cook.. i'll try that and see if it helps! thanks for the advice!

Is there a way to get rid of the extra adenosine receptors cause by the use of caffeine?
Go about 10-20 days with NO caffeine at all, and they will fade. When you drink caffeine again it will have a similar affect as it would as you first started drinking coffee, however you will rebuild a tolerance quicker. try to take these brakes once every other month so you don't take irregularly high amounts of caffeine, and so caffeine keeps its energetic affects.
Hi Dave,
I've discovered a way to get rid of dependence on caffeine and feel more alert, awake and less fatigued. Apparently caffeine causes the release of _histamine_ which triggers the _H3 receptor_ in the CNS.
So the problem ain't _adenosine_ per se. It's more to do with the _glutamate-glutamine cycle._
I fixed it taking a tea spoon of _l-glutamine_ (the precursor to l-glutamate) in a bit of milk twice daily.
I'll post a longer comment with more info.
O. Rood I used to take L-glutamine pills once in a while (muscle rebuilding purposes). Now I eat the L-glutamine gummies from GNC. But I had never heard that they could help to feel more awake. It'd be nice it if did.
Let me know it goes!
Hi Dave, that's interesting. Muscle _rebuilding_ purposes .. or muscle _building_ purposes ?
*It worked for me and for others who were fatigued and drink a lot of coffee to compensate.*
The chemical structure of glutamine is very similar to a neurotransmitter which is required to be alert, awake so that's no surprise.. especially if I'm correct that long-term caffeine consumption ends up exhausting the available supply of said neurotransmitter and/or its precursor l-glutamine in the CNS.
What's surprising is that of the layman info I read online most is contradictory or just plain wrong. I mean.. _it's one of the most abundant amino-acids in the body_ (even if it is locked away in muscle tissue or other cells) so saying it is a 'poison' (as some websites claim) makes no sense.
However.. everything in moderation. It can be readily metabolized by cancer cells so.. yeah, I wouldn't recommend it to people who suffer from that ailment.
I'd be more concerned about someone suffering a placebo response after reading some of the strange ideas on the web regarding glutamine.
Average absorption of tablets is usually not 100% or even 50% depending on the ingredient.. so I took a tea-spoon of l-glutamine _powder_ in a small bit of milk.
According to GNC (which you mentioned above) they say: _"By micronizing large molecules into smaller particles that are easier to absorb"_ .. it will make a "better" product.
...Treating a fine-powder of a _reactive_ soluble amino-acid in some kind of chemical cocktail to change its 'size' sounds a bit OTT and would by definition attempt to _break down_ its molecular structure to "micronize" it. I would be extremely sceptical about any 'treated' or 'concentrated' l-glutamine supplements.
Also they charge $20 for 60 of their RapidDrive® Performance® gummies.. at 306g per pack that's 5g per gummie.
I paid around $6 for 500g of powder and took a rounded teaspoon which'd be a little less in weight, except the powder wouldn't have all the extra ingredients that your gummie has.. sweetener/sugar etc so it probably would be more equal than not.
So if you didn't notice any effect from this RapidDrive® Performance® version I'll probably avoid any "micronized" or "treated" l-glutamine in the future and stick with what I know works.
However if you're into fitness and body building then you probably wouldn't have any issues with chronic fatigue anyway so the point is moot.
Also.. knocking back 100ml of milk with a teaspoon of equal weight to one of those gummies would deliver a higher amount to the blood stream than sucking on a gummie for half an hour.
(If that "micronized" form actually does anything and hasn't broken down completely this may explain the difference.)
The blood has quite a considerable amount of available glutamine (in different metabolized forms) .. and it _can_ pass the blood-brain-barrier, so perhaps it is the quick boost that helped deliver it to the CNS in my case.
The only other thing that springs to mind is that it exists in a stable form by binding to another metal or 'salt' and that the micronized form bound to some other molecule which inhibited its ability to cross the blood-brain-barrier easily.
I'm not an expert nor a chemist so I can only speculate.
(And if UA-cam didn't show my previous comment, I hate them.)
it's funny how caffeine isn't considered a drug yet we wouldn't think of giving it to little kids just like alc, weed, etc...

Do the new andenosine receptors wear off after you havent had caffiene for some time?
that is a great question.
They do when they're no longer in use. So if you constantly keep your energy up by other means (physical activity or whatever) they won't go away as fast. The brain is constantly changing and allocates energy to make stuff it needs more.
Does anyone else feel tired or dizzy when drinking coffee?

2:33 Logic? You get tired when the caffeine leaves your system late day-time, so you drink more. When going to bed, you don't want caffeine sticking around in your body.
This video is very misleading and half-done. They don't even mention that there is more than one type of adenosine receptor affected by caffeine, and that there are studies suggesting that one of these receptors doesn't produce tolerance. One receptor is linked more to the performance-enhancing effects that go away, the other potentially allows caffeine to keep you up at night despite your caffeine tolerance.
can you get addicted to coffee?
Indeed you can. I went through a coffee addiction once.
Of course dude, the dopamine release process in the brain it´s pretty similiar to that ones that´re caused by stimulants drugs like amphetamines or cocaine.
I think it depends on the person. I drink coffee at work to stay alert, but I don't even think about it on my days off. However, there are people at work who admit they are addicted to caffeine.
It is a mildly to moderately addictive substance (depending on the person). But the people comparing it to the addiction of meth are insane. I drink it every weekday morning to get up for school, but can easily go without with little negative effect other than being slower to shake off the morning grogginess and an increased chance of a migraine (I got migraines long before I started drinking coffee, and when I started my migraines sharply reduced, so this is to be expected.) I went almost the entire summer 2 years ago without coffee and was just fine (I never had to wake up early, so I didn't need it.) As long as you avoid excess (I recommend keeping it to about 16 oz a day) your fine.
Yes, but I'd say it's only mildly addictive. Pretty much the only thing you may experience as withdrawal symptoms is getting a light headache and feeling tired in the middle of the day. If you enjoy the taste you might crave for it in line with other food/drinks. Keep in mind it can interfere with sleep if you dont avoid it for several hours before bedtime (you should avoid it minimum 5 hours before bedtime is what I've read), and when you don't get enough sleep, you may compensate by drinking more coffee.
You guys should make one about Kratom.

With its stimulating effects, it’s easy to understand why coffee is the second most traded commodity on earth after oil. For many, it keeps us awake and moving through our busy days. But how does it work? What exactly does coffee do to your brain?
2- Whenever you’re awake, a chemical called adenosine slowly accumulates in your brain and this adenosine binds to receptors which slow down brain activity. Ultimately, the more adenosine there is, the more tired your brain feels. Which makes sense as the longer you’re awake, the more fatigued you become. Conversely, while you sleep, the concentration of adenosine declines, gradually promoting wakefulness.
3 - But it turns out that the caffeine in your coffee is incredibly similar to adenosine in structure. The caffeine works its way through your bloodstream and into your brain where it starts to compete and combines with adenosine receptors. But because it’s not adenosine, the sleepiness effect isn’t felt. Adenosine can no longer bind, meaning its calming properties are diminished. Which is great for you when you’re feeling tired.
4 - However, with long term use of caffeine, your brain responds by creating more adenosine receptors, which means more caffeine is required to elicit the same response. It also means that when you try to quit drinking coffee or miss your daily intake, you might experience some withdrawal symptoms and feel more tired than you would have before you ever drank coffee. But the caffeine doesn’t stop there.
5 - It also stimulates the production of adrenaline - you know, the fight or flight hormone. This increases your heart rate, gets your blood pumping and even opens up your airways. Furthermore, it affects dopamine levels by preventing its reabsorption in the brain, which makes you feel happy. In fact, this is the exact same thing that cocaine does, just to a lesser degree. It’s a drug after all.
6 - This dopamine stimulation is also the aspect of coffee that makes it moderately addictive. So, can you drink too much coffee? It turns out there is a lethal dose of caffeine, which is somewhere around 150 milligrams of caffeine per kilogram of your body. This means if you weigh 70 kilograms, you require 14,000 milligrams of caffeine to overdose.
7 - Put into perspective, an average cup of coffee contains roughly 150 milligrams of caffeine. Meaning if you’re 70 kilograms, approximately 70 cups of coffee would kill you. However, you would have to drink those cups all at once, making it effectively impossible to overdose on caffeine from coffee, since you wouldn’t be able to physically fit that much in your stomach.
8 - You would also start experiencing mania and hallucinations before getting to this point. Caffeine also has a half-life of around 6 hours. So, if you drank a standard coffee with around 150 milligrams of caffeine, after about six hours, there would only be around 75 milligrams left in your system and you’ll be feeling half of the effect.
9 - And 6 hours after that, you’ll have 37.5 milligrams, leaving more room for adenosine to jump back into action, which is why you may reach for another cup throughout the day to remain that glorious alert and energetic feeling. So, drink up and enjoy the buzz while it lasts.
10 - And for all of you who are in school, while we know that caffeine is key, so are good deals on textbooks. So, we’ve teamed up with slugbooks.com to get you the cheapest prices for the books you need. All you have to do is head to 10 - slugbooks.com/asapSCIENCE and search the ISBN number of the books you’re looking for. SlugBooks will then compare prices from all across the net.
11 - Seriously, we know how expensive textbooks can be so hopefully this will save you some money. Got a burning question you want answered? Ask it in the comments or on Facebook and twitter, and subscribe for more weekly science videos.

So, one night, I needed to do lots of school work and I was tired and I decided, “If one cup of coffee doesn’t work, why not drink several?” I don’t know how many tablespoons of coffee I put in my cup, but it was a lot. I put loads of sugar in too, and the whole thing tasted like crap, but I needed the energy, god dammit. I certainly got that energy! I was shaking all over, my skin was flushed red and white, I couldn’t feel my legs, my heart was pounding out of me and I had terrible anxiety. Learned my lesson. Will never do that again 😂
Caffeine didn't have any effect on me for years but ever since I started restricting my food intake(due to my disorder)every time I drink coffee I can't sleep for days:/
"long term use=creates more receptors"!ha.!! thats why i dont drink coffee
That sounds much worse than it actually is.
I try to treat caffine the same way I treat alcohol. Even though the effects are wildly different, I want to enjoy it now and then without being dependent on it.
I only drink coffee when I really need it so I dont get a tolerance and feel like crap without it
Watching this while high af on caffeine
Did anyone else laugh at the 3rd drawing of the tired zombie or was that just me 😂
