Vitamin D, nitric oxide, mitochondrial melatonin... and now testosterone. Living in the PNW, I make sure to get 20 minutes of midday sunlight every chance I get. Feels so good.

Anytime I can get Sun on my balcony in the morning I do it. I don’t care if it’s 5 degrees outside, I feel so much better and my sleep is SOOO Much better as well

I spend an average of 2 hours or more a day in the sun. He's my friend. 😊💪💥

I definitely experience an increase in libido when I'm out in the sun, especially at the beach.

Makes complete sense. Lots of nuances of course. We all need more time on the nude beach. Sun, feet grounded to the earth, sea air, ....and of course good nutrition, exercise, social interaction.... Right!!! Most of what we should be doing is Free

My husband is 43. Last year he bought a convertible that he works on in the driveway all summer. He's a changed man.

Was mowing the lawn shirtless today for more than an hour. Flexing on the elderly neighbors who are all out of shape is just a bonus to all the Vitamin D.

You may be young enough that you don’t remember when the campaign started to get people to lather up with SPF (with mostly good intentions). The idea was to reduce wrinkles (vanity) but more importantly to reduce skin cancer. Skin cancer is very serious but it got to the point where some people didn’t allow any sun exposure. After this campaign started we started to see odd health symptoms broader than just lack of vitamin D. It’s yet another example of the medical community promoting bad behavior.

This really works! I’ve been focusing on light and circadian rhythm for the last few months and I feel great. My sleep is deep and restful. I’m energetic and alert during the day. My mood has also never been better.

I now understand the appeal of sunroofs in cars/ convertables. I was always like "ugh sunlight i dont need my post acne scars getting darker, risking premature aging, having uv light damage my eyes, give me an uneven skin tone" i went all out with sun protection lol its exhausting and took me a few years to mostly get over my "heliophobia"

A ton of data is emerging that sunlight has a ton of positive effect in so many different regions of health. Thanks for adding to this info!

this is one of those things, my wife and plenty of other women/people focus so much on downsides of tanning/sun exposure, but there's definitely gotta be a sweet spot, and it seems like it's rather vital for our bodies to be optimal both physically and mentally

I had Vitamin D deficiency. Started sunbathing a year ago. I walk after I eat shirtless in the sunshine. I feel more confident.

Sunmaxxing is my favorite activity

I find it interesting what (experts ) who don’t live in the sun say about the sun. Im in the sun everyday last 40 years 6-10 hours a day.. Aloha

Not being petty at all but wanted to sincerely thank you for stressing "biological females". Need more of this right now, ish is getting waaaay out of control these days. Love ya Mike! Keep fighting the good fight brotha!

Sun is really energy 🌞 Thank you, Mike!

Great video and interesting study. I’m in Texas and I try to go out into direct sun for at least 15 minutes a day with only shorts on. I’ve always done this to keep my vitamin D levels at an optimal level and to manage my psoriasis. Now it seems like there’s another benefit to this. At least now I have answers for when my wife asks me why I’m such an animal with her LoL.

Cold Showers and Sun

Well I'm from Morocco and we're not short of sunlight and I loooooove sunlight I'm a sun worshipper and I love lifting under the sun on the beach lol

Beyond the sun's beneficial effects on hormonal levels, there is a study showing that sun exposure maybe a pivotal factor, early in life, in people preserving their visual acuity. An ophthalmologist posited that one of the reasons that we see so many children and young adults having to rely on corrective lenses is because the modern world is depriving them of sun exposure early in life, and this lack of early childhood sun exposure prevents the eyes from growing into the correct shape in order to have optimal vision. Many times, when speculating about the cause of this pervasive poor vision in our population, we blame either genetics or too much screen time. Its probably not the TVs, iPads and mobile phone screens that are directly causing these declines vision. Instead, these devices are INDIRECTLY causing the deterioration of vision early in life, because they are REPLACING time that would be spent outdoors.

I live in the Washington DC area. I believe that the natural vitamin D we get from the sun balances out all of our hormones. I normally weigh five pounds less in the summer time than in the winter. I agree and think this is due to higher t levels and also the balance of all of my other hormones due to getting more sun in the summer.

This should be common sense! Woe unto modern humans who have forgotten the basics of how to live!

Thanks Mike for all you do.

Thank you for sharing this info!

Thank you Mike!

My favorite health channel !!

God, I love your videos. Constant reminders and facts about self care and keeping my head in the game. Coming from someone who has autoimmune, MTHFR, DAO, NO3, Celiac prone, lactose intolerant and a non-necretor.

Thanks for putting this stuff out there. Great channel.

Brilliant vid, Mike. Heaps of great info.

Great information! 👍 Thanks Mike 😊

Thanks Mike!

Agree. I'm living in the South if Spain. After bathing Sun hormons are on high level

Amazing! This could be a game changer, I'll definitely be actively getting sunlight now

Love sun exposure. Thanks again Mike. You always have great information, appreciated! 👍

THANK YOUUU!!!

I never bought into the 'be afraid of the sun' thing; where I live sunshine is amazing if we manage to get some!😂 Enjoy🌞🌞🌞

Thank you for sharing scientific articles in a concise manner. Appreciate it 🙏.

Great video. Sun exposure just feels so good in every way.

Wow✨✨✨✨Thank you💜

Great reason to strip off in the sun 🌞 I've never used sunscreen. I just go to shade when I've had enough sun and I think we know when we've had enough.

Great video. Been getting sun on a daily basis this summer and certainly helps with sleep and mood. So far I consider it safe and effective!

Awesome content!

Thanks for the info

Fascinating

That's super interesting! Thanks for putting out. It gives me another motivating reason to get out and get a little sun every day!

I used to be regular and fertile, I lived in México and then I moved to the uk and I'm sure the lack of sun light, as i used to take so much sun screwed my hormones and I am perimenopausical at 38 started. I'm healthy I train hard now for 10 years, my family didn't have that problem but I do

Great info. I try to take lunch outside and for walks in the sun with my shirt off, your right it does make you feel good. I found since being low carb and a healthy no seed oil diet etc I can spend days out in the sun and do not burn. I firmly believe in not wearing sun glasses either.

thanks for your videos :)

Excellent topic and easy, effective solution! Mother nature has what we need and modern society is doing everything possible to keep us from her.

Great info! Thanks 4 sharing, n also love Dr Huberman’s info! 🧠💥💪🏽👍🏾💯

As a fair-skinned person who hasn't even reached age 40 yet, but has already survived 3 skin cancers, I feel you were a bit too cavalier about the very real possibility of skin cancer from sun exposure. I'm not saying we shouldn't get sun exposure. I still try to get regular sun exposure for all the benefits you mentioned. However, that doesn't mean I and other fair-skinned people should go out in the sun, potentially at mid day when the sun is at its most potent for us (since you didn't specify) for 25 minutes every single day. That is honestly too much for us. You did mention hyper responders, but you didn't mention that people like us should really be careful and potentially limit exposure to only 10 to 15 minutes before putting on lotion, particularly when getting the exposure around mid day in a hotter climate like Southern California for instance. After the cancer removal on my face (Mohs Surgery) I had a golf ball-sized deep and open wound. If I didn't have a spectacular plastic surgeon close it up with a flap technique without the need for a skin graft two weeks later then I would have had to walk around with a deformed face the rest of my life. And even with great luck with quality health care and surgeons I will still have the scar for the rest of my life. I do believe you mean well and are overall providing good information to the public, but I urge you to use a little more caution and thought for potential consequences when educating your audience on the findings of research studies. Thanks.

Good vid as usual Mike. I'm 51 and very fitness focused, but probably still more sensitive to testosterone swings due to age. And I can say without a doubt my libido is higher in the summer.

I’m doing a personal case study on this - the data seems to agree with the research it’s extremely fascinating !

Solid video Mike , we are spending way way to much time indoors …I spent a good portion of the day outside . Little biking , play on the rings and some walking . Life is good . The sun is a non negotiable part of my “diet “ !!! And yes something about sunning the boys seems to ramp up the testosterone lol

I live on the East coast and have been doing 20 mins of unprotected sun exposure this summer. I feel a 100x better and have not been sick with anything. Not sure how I'm going to feel in Fall/Winter....I might need to move to FL and be a "snow bird" in my 30's.

Very interesting..this explains it..Summer R❤️‍🔥mances. I love Sunshine..miss it in the winter. And working out in nature with the warmth and shine of the sun is so healing and energetic! It's no wonder my happy space is a place in the SUN☀️Thanks for this Lovely and Timely Truth❣️ Sunshine + Happiness = A Whole Lotta Love. 👍🌞💖

So glad I live in a place Sun is the norm daily.

Sunseual healing 😎

Great content. Love from Taiwan.

Wow 🙌🏽 great content 💯 I’ve been making a conscious effort getting full body exposure 🌞 I gotta say, it’s been making a noticeable difference 👀

I used to live in very sunny areas as a kid and yeah I can see the difference with that and living in a less sun exposed location.

i can feel it...the key is a little at a time,so you don't burn..Sun is very intense where i live....

At least an hour of Southern California sunshine daily, never burned because no seed oil in my diet.

Yoooo!!! He made a video of the topic I was interested in. Time for my wife and I to go hiking.

I have to agree!

I live in Dallas and just 5-7minutes front and back in the summer each day in my shorts is enough to have a full tan so I’m supposing that would be a good indicator of a sufficient amount for the amount need here. I do more like 10 minutes in winter months.

I think the skin cancer scare has caused much of this. And everyone wearing sun screen I think prevents humans from getting the full benefits of the sun

Heather Shepherd has an e book on the Sunlight Rx program, I’m actually starting it this past week, already starting to notice subtle changes for the good. 👍🏻

Please interview Dr Courtney Hunt! She can elaborate more on this topic!!

Dr Dray would so not like this lol. She’s covered and would say nah! I’m with you. Direct sun for a bit is so healthy! I would rather have a few wrinkles & freckles then to not enjoy the sun. Thanks for all the real research!

The birth control hormone impact is under appreciated.

Love this and I'm a "sun worshiper"....because in winter in the Northern Plains, there's not as much sun. Please help us with that problem. I still go outdoors daily through winter months to keep the blues away.

So I did come back a third time like I had mentioned in my second comment and I did have an interesting thought about way things were back in the day especially when they had to hand weave clothing and if you think about how breathable and lightly woven linen was, people likely got more full body sun exposure just from wearing white linen, versus today's more durable tightly woven cotton or even worse polyester. So definitely clothing can be an issue in how we get less sunlight against our bodies besides the fact that people stay inside and enjoy air conditioning or artificial heat just to avoid being uncomfortable which is a much better stress I would say then having anxiety or depression from isolation

I came back to listen to this again because after eating a large meal, I went down the trail in my Rangers panties they call them without a shirt like I tend to do on Sundays after my two meals I eat after training my legs, and it is interesting though thinking about it because I tend to feel more excited more quickly after going for a long walk in short shorts without a shirt, and some of that can be from some of the smiles and waves and greetings from some of the girls out there running or riding their bikes, because some say that even talking to beautiful women can spike your testosterone, which of course enhances your mood, but it is interesting that even the sunlight can do that because these things are pretty thin so maybe in a way I am getting full body exposure, aside from my bearfoot shoes covering my feet, yet I do find this video extremely interesting so I will probably listen to it a third time

HIH, you are a very brave man... Humans have been in the sun for some 4 million years.

I'm looking forward to getting back into the habit of getting this extra sun to boost testosterone now that its warmed up here in Chicago. Thank you for posting this!

Am also in Seattle. Am being avaricious with the summer these days. we have so few in a year.

We Israelis come up with the best studies, Mike. Good one.

So that’s why they want to dump a bunch of dust in the atmosphere to block sunlight🤔

Quality content! Great to see the understanding of how pheromones can impact attractiveness. Pheromones are actually a byproduct of our microbiome. Different outbreaks of fungi like athelete foot and dandruff are other symptoms of imbalances. We are just hosts to bacteria just like every other living form. Understanding that is understanding life and the importance of this planet to our survival.

Makes sense, I always get the horn in sunny weather.

Ben Greenfeild did an article on sun exposure to your sack has a big effect on testosterone production. Same 20 min time exposure. I think he did some testing on himself and got some really good results. So your video here is not surprising but I still watched the whole thing, I appreciate the value you give.

People are neurotic about avoiding sun exposure. I know so many people who have been prescribed vitamin D from their GPs, and they're the same people who slather on factor 50 (in the UK) and religiously avoid the sun. Obviously no one is advocating baking yourself to a crisp, but we do need sunlight. I've noticed a huge difference in mood from increasing exposure and even tentatively and conservatively using sunbeds when the light level is low in the winter time. Getting light into your eyes on the morning is amazing too

I have the windows down, music up, and sun roof open in the car almost year round. Don't know if I can ditch sunglasses though. My eyes are blue and pretty sensitive. great study though XOXO

Beneficial UVB Sun exposure in Northern Hemisphere, is from late March to late September. The sun doesn't get high enough in the sky during the other months.

I guess I’m lucky enough to live in Las Vegas, lots of sun exposure during the summer months. Probably can’t do a “full body” tan unless I wanna give my neighbors a show

Hi Mike! Thanks for the great video again. Question: What is the optimal vitamin D3 blood level (in nmol/l)?

With a very rare exception of when I’ve been in the sun all day I’ve not worn sun cream in several years. If I get skin cancer so be it, the benefits of being in the sun and avoiding all those chemicals far outweigh any future drawbacks.

no doubt i was out there for a good 4 hrs today gotta couple new holes in the hallway drywall but other than that i feel phenomenal💪

That's a tough one, I live in the tropics so skins cancer is extremely bad here due to constant level extreme UV levels. So maybe 5mins per day will do enough.

Lol... I'm in Phoenix. 20min equals blisters.

I spend 8 hours in the sun everyday, my testosterone should be bussin!

I always found it interesting that people who live further from the Equator have higher cancer rates such bladder cancer, breast cancer, colon-rectum cancer, lung cancer, oesophagus cancer, oral cancer, ovary cancer, pancreas cancer, skin cancer and stomach cancer

at my region mid day sun is very hot in the summers, I believe it depends on where you live because 20 minutes in that sun will burn you for sure

Vitamin D baby!!💪

hope that new NAC is shipping soon.

Vitamin D3 has helped me a lot. 💪

I walk everyday shirtless in the sun at 10 am I got jacked up 💪

I am concerned about how sun exposure leads to skin cancer. Could you explain in greater depth the risk benefit analysis you are making when encouraging prolonged sun exposure?
