Here Comes The Sun: The Science of Vitamin D
Вставка
- Опубліковано 8 кві 2024
- When you hear the word "photosynthesis", you probably think plants, but we also "make with light". Our skin uses Ultraviolet B light to synthesize Vitamin D, and it's pretty essential to our wellbeing. But what is fascinating is the delicate balance between making enough Vitamin D and being at high risk of skin cancer. And the molecule that completes this menage a trois is the one that fundamentally underpins racism and things like "fairness creams".

PLEASE NOTE: 2:52 The Ionizing and Non-Ionizing labels are on the wrong sides. Gamma ray/UV is the ionizing side and Microwave/Infrared/Radio is the non-ionizing side. UA-cam used to allow annotations but now they don't, so I couldn't edit the video. Thanks for the patience
Was about to ping you regarding this! There goes my 5 seconds of fame😂
I was going to comment this
Also forgot to mention gamma rays turn a person into a mean, green and lean violent machine.
Sun? what sun? its permanently cloudy thanks to your lies about GLOBAL WARMING rubbish propaganda
I was confused initially. Thank you for the clarification
the amount of research that has gone into this video is just amazing. Thank you for this informational video . The best video in entire youtube about vitamin D ..
As a brown person living in Europe, the part about being vitamin D deficient is true. My first year I was severely ill during the bleak, grey and depressing autumn and winter. GP adviced tested and lo, and behold vitamin D deficient. Started taking pills and watched my well being became better.
Of course, diet and excersize ALWAYS play a role on your overall physical and mental health. They are non negotiable, and so is Vitamin D.
Thanks for covering this Krish. Your content helped me critically think over this subject matter. There was a phase where even doing groceries became an upsetting chore (where are the vegetables coming from, are they organic? Do they sell A2 milk here? Yoghurt? Etc etc.
Glad I grew out of it relatively quickly. Having a healthy diet, brisk walking at least 20 minutes a day, and the sun light matters more than that croissant with a coffee on a sunday morning at an artisinal bakery.
Thankfully here lot of foods are fortified, from rice snaps to corn flakes ❤️
Our ancient saying "Sun is the perceivable God."
Yes indeed
If ever God could exist, then The Sun is the only God
@@RahulRaj-mu1kg You can see God every where in many ways and many forms Even if your are blind. 🙏
@@Yk-fu5su Then I am also a God. You too are a God
The only believable God
Even moon is visible due yo the solar radiation on moon's surface
Vitamin D is not just limited to the bones. It is the most important vitamin and it has potential to cure any disease. People don’t understand it’s importance because it’s free
Lovely Krish. Amidst an explosion of misinformation you come across as a whiff of fresh air with real testable information. Kudos. Thanks for this.
man, I love this type of videos. Just tons of information on why things are they way they are, and tips on how to make things better.
I believe that the labels on the electro magnetic spectrum for ionising and non ionising radiation are on the wrong sides by mistake
@krishashok: please consider re-uploading the video.
Will fix that
I was about to type that
Me too
Great video as always - loaded with insights😊..btw, you're leveling up your editing game quiet significantly with each video 🎉
After long time of hearing and confusions about Sun and vitamin D, finally getting some clarity, thanks!
At 3:12 you have to switch the caption. Short waves are ionising. Long waves are non- ionising. You have written the opposite.
Wow...krish...you make everything so easy to understand... I'll never stop saying that 😅 All your video topics should be taught in school to kids, instead of subjects which are never used in general life.... My heartfelt Thank you 😍💕
Very well said
Hi Krish,
I love your video! Very informative, backed by science!
Many thanks.
Brilliant video and well put
I truly enjoyed this video. Thank you 🥹
I was looking for a reliable video for this info from long time. It has clarified all the doubts I had, especially 'fact Vs myth', even many experts are divided on it, creating all sorts of confusion. Thank you!
Thank you for this very informative content!!
This is a fabulous one. Many of my doubts have got cleared. Thank you
Beautifully explained in simple words
Amazingly explained!
Great video as usual Krish!!!
How much skin should be exposed for optimum absorption?
Krish, I wish you were my professor! Thank you for your selfless work and time 🙏🏽
marvellous info...
Amazing❤. Such a deep research u do. Very educative blogs. Thnx
Thanks a lot. Very informative video.
Beautifully explained.
great content sir, great work
One of your best!
‘Racism is just skin deep’ - Wow! - BTW Krish, you resemble ‘the professor’ from Money Heist !
Thank you for such a good explanation...too good educative 👌✨
This is on another level, sir you are doing service not posting content, as always science with comman sense is needed
Thank you for the great content! ☺️
Excellent....
Thanks bro... Much needed help
Thank you, very well explained
Awesome, Krish!! So simple to understand. BTW I have been prescribed Vitamin D supplement in the US and after this video I have learned the reason. Thanks!
Amazing vidoe!
Excellent Sir.
Interesting clips very well explained, as usual. Bravo ❤
Very informative but so easy to understand ❤
Beautiful video
I've officially added this to my 'Watch Every Month' list.
Simple, scientific, concise,... such an amazing video... thank you for your efforts sir...
Thank you!
Brilliant!
Very useful information.
I remeber when I asked this question and you said to read articles and I did read articles from Evolutionary biology and this is exactly what I read. Little bit more details in migratory pathways but I don't think people need to know that detail.
Amazing video!!!!
Wow that was just superb thank u sir
Wonderful video Krish👍 very informative and useful. Thank you !
Glad you liked it
Very good information 😊
Wonderful
Great video
Labels on 3:12 need to be the other way around. Might be worth putting up a pinned comment to mention it so it’s not too confusing.
Yes. Will do!
Thanks Krish for the excellent video. This clarifies a lot of the misconceptions.
Thank you
Hi Krish, thank you for this video, its really useful, wanted to ask, is using sunscreen everyday safe for teenagers and adults?
Excellent video 👍🏻
thanks for your work and wish you all the very best to keep going. W.r.t Vitamin D does ergosterol has any role? Pl clarify. Thanks.
Off topic,but really love your t shirtttt in the thumbnail can you tell where you got it pleaseeeeeee?
So informative! Thankyou!
Refined oil!?
Refined means something improvised,most people believe this
8:45 appreciate more insight into time spent - does it need to be 45 mins at a stretch or can we do in breaks of 10 mins? Also, how much body coverage (%) ??
Good information,Nice 👕
I think there's a mistake in the labels at 3:12, it should be the other way round...
Learned a lot thx
Sir u r a priceless treasure to all of us
True! From Canada!
how to exact supplement and balance Vitd3 k27 & magnesium according to age weight and geographical area like india, kindly clarify Sir @krishashok
Well done
Useful points in this video.
Necessary to have normal levels of Vit D ( like every other Vitamin).
Get your levels checked.
If deficient, remedy thru Diet/supplements / exposure to sunlight.
All else is padding.
Such a detailed explanation 🎉
Glad it was helpful!
Sir I’m a doctor and a history buff. I love your videos for their accuracy and humour. Is there an audiobook of Masala Lab with your voiceover?
Thank you for the great content as always. I always save your videos.😅❤
Very well explained
thank you
@Krishashok
Is there any connection between reduced Vitamin D and Diabetes?
Thank you❤
Any specific time of day for max vit d absorption & least uv damage
Good info... one question: What happens when people apply cold pressed oil like coconut oil all over the body and sit in the sun? I have seen in the case of my grandfather and other elders that their skin does not tend to age or form wrinkles so fast and they had good Vitamin D levels throughout their life. They would sit in the sun at least once a week for about 30min or so...
Hi Krish sir, I think there is a mistake in labelling of the wavelength as to which is non ionising.
What a knowledge…. Keep it up man
Thanks a ton
now it is hot summer here in Karnataka Udupi where i live...so going out in sun between 10 am to 2 pm for 45 minutes is just out of question as the perspiration willl be unbearable....i do have sunlight in the morning at around 7.15 to 7.45 am and evening around 5.15 to 5.45 pm..i hope this is more than enough....In any case thanks a lot for the detailed explanation
Thank You Krish. Like the Beatles song " Here Comes the Sun" title for the Video.
Can we wear cap during the time we expose in morning sun or need to directly expose face and other parts directly to sun?
Vitamina K2 should also be consumed with Vitamin D supplement.
do we need sunscreen at all?
Beyond the sun….The T-shirt!! 😂 Jokes apart…really informative and well researched content! Vit-D deficiency is so common. Much needed awareness video.👍
10:20 so trueee. I’m a South Indian living in Canada and the lack of sunlight is brutal! Taking vitamin D supplements was a game changer.
Seasonal affective disorder (SAD) is super real in the latitudes closer to the poles during winter times. Idk if it’s psychosomatic but I felt much more normal during the winters with supplements than without.
Possible to also share the effects of deficiency pls?
Good one sir. How vitamin D affects mental health is also a factor to be discussed please. May be next time❤
Thank you. Could you please do a video explaining what are "Vitamins" and the common myths about them.
You would make an amazing teacher/professor/doctor. Whoever pushed you into engineering?
Your T shirt.... ❤😊 And as usual Great Content!
Appreciate the way you were able to articulate complex (highly technical) content in too little time; i will need my wife's advice to dig deeper (not on physics part); i may not hesitate to watch it 2-3 times more to further understand the nuance presented. good to learn from you and thanks for sharing your knowledge :)
Thank you
1.30 hrs per week means ... It's enough to get in single day , Which produces vitamin d for a week? Or to get it 2 days once?? Can you elaborate this in answer.
@0:37 what is measure of energy?? Please clarify
Hi! Can you please make a similar video for vitamin E ? Thank you!
“If we had no atmosphere, we would not exist”. This is the best line. There is no requirement of us to exist in the first place.
Love the t-shirt logo
Would there be any difference in vit d production if you are normally dressed or fully covered when exposing yourself to sun?
Half an hour between 10 am to 2pm in summer causes skin burn . Does it safe
Good exposure to the need of Vit B12& Vit D/D3
One doubt..
If our lifestyle and job are letting us only 2 hrs to 3hrs of sun exposure /week, then is there a need for sunscreen at all except on beach holidays
Excellent explanation - is your graphic at 2:56 correct? You mentioned microwave is non-ionizing and UV is ionizing. However the graphic is other way around.
Yes. -i have pinned a comment stating that the picture is the wrong way around. Unfortunately UA-cam does not allow captions or edits
