Interesting theory. I think we are low on vitamin D and melatonin. As we get older (I’m 67) our skin is much dryer, and it is the oil in the skin reacting with the sunlight that makes D3. Probably one reason why older people’s immunity is lower. I agree that there are many benefits to sunlight besides vitamin D production. There was a small study done in a hospital in Brazil durning the Covid pandemic where Covid patients wore vests that either gave off red light or wore vests that did nothing. No one was told which was which, so double-blind. The one’s who got the red light reduced their hospital stay by 8 days. At least supplemental vitamin D is very inexpensive compared to prescription drugs. I also supplement with melatonin.

I so wish you still saw patient!

People are so brainwashed about VD, that they look at you like you are crazy when you try and tell them to just go out without sunglasses and build their solar callus so that they have enough in the winter.

This does make sense. Does cold exposure help with melatonin production? Or is the cold for mitochondria mainly? Thx

Wow you are worth your weight in gold! Ive been thinking about this issue for a few years, now thanks to you I have the answer. I work outside and get as much sun as possible (for the UK) I also use wood to heat my home. How lucky am I. Your content is some of the best I've ever come across.

Time to set up an interview with Dr. Gundry and set him right on Vitamin D supplementation. I always enjoy your videos Carrie! Thank you for what you do.

Thanks Carrie, this is a great, easy to understand summary. I have been following circadian principles for awhile but this is video is great for sending on to family, friends for them to be able to understand the real world implications of blue light. Will probably send to teachers at my kids' school as well. One suggestion/request :), I would love to see additional information on how chronic blue light exposure during the day (from screens, from overhead lights, etc) is damaging as well. Again, mostly because I would like to send info on to my kids' school so they can see how improvements to the light environment at school (during daylight hours when kids are in attendance) can positively impact students.

Everything you're saying makes perfect sense and seems logical. However, a couple summers ago when my D3 was low, we built a little beach on the lake on our property. I took my 3 kids out there nearly every single day for grounding and sunshine without sunscreen for a couple hours. I wasn't taking D3 supplements. At the end of summer in mid August, I had my D tested and it was still low (24) and in fact one point lower than before! I was shocked. I'm not convinced we can easily get enough vitamin D from the sun only in this modern life. I don't know why, but it certainly did nothing for me. :( (Important to know, we eat a whole food diet, no rx meds, I don't wear sunglasses, I prioritize sleep and our location is Southern Indiana.)

Since learning about how suspect all synthetic vitamins are I have radically changed my thinking on vitamins. Thank you so much - this is so interesting, along with your clarity and intelligence you are making a real difference.

Thank you so much, Carrie, for such important information that I have not heard elucidated this way elsewhere. Fascinating new info to me about this receptor's connection to melatonin!! Renaming it makes everything make sense. Here is a slightly different question.... where would you recommend someone start if they have a totally reversed circadian rhythm, i.e. the tendency that is somewhat common in the population of people with severe neuroimmune, chronic illness -- basically, being awake all night until sunrise or later. I am aware the principles that you teach... and making a big leap or change in my schedule has failed for me many times when I have tried in different ways, because it always involves some pushing and stress that I don't seem to handle. Have you had people in your teaching groups with this type of severe circadian dysregulation who have been able to make incremental or gentle change? Thank you, grateful for your work!!

Love your no-nonsense approach that focuses on root causes and solutions, not supplements. 🎯

What about the fact glucogenesis breaks down muscle and thymus tissue? Ketosis also down regulates thyroid function and increases stress hormones so how would that be beneficial in any way? Also, what is your take on Dr Ray Peats studies that darkness and cold are highly stressful and more people die and develop metabolic disease in winter and in northern latitudes? Why do we want to go back to scarcity and force our body into emergency backup systems?

This was very interesting perspective. What you are saying I can see anecdotally in myself and some of my personal training clients. I even realized that the body part that is involved in a traumatic event, even if it isn't damaged, is the one that basically takes the brunt of distorted tissue effects. For example, you receive terrible news over the phone, that hand you were holding the phone with or that side of your face can store that shock energy. I too am a firm believer in the use of foam rolling. Now I know another aspect of why it is so effective.

Love the optimism but I hate the winter 😢 i am physically and mentally deprived in winter, I survived bsc of summer

It’s been a game changer for me regarding psoriasis. I believe mine is histamine related and when I started following the sun, ditched nighttime blue light and drink good water with salt my skin has turned around. My body was about 80% covered now I just have some patches on my trunk and back of neck. We’ll see how I do this winter but I’m going to eat seasonally with a lot of fish and see how it goes.

Can we take melatonin supplements? Thank you 🙂

Thank you Carry for pointing out such important info!

Planning on semi naked morning at Sunrise for 15 minutes for air induced CT coupled with skin Solar panel activation this winter!

So, I don’t have to leave my family and move to the equator as JK told me? 🤪

Thanks so much for this perspective, Carrie. It´s uplifting. I remember the first time a family member said around Christmas: ¨well, at least the days are starting to get longer now.¨ It really helped me to shift focus and enjoy winter as much as possible. All the best :)

Wow I really love your content. I work outside and my days are very long in summer but during the winter my days are really short and I can spend longer in bed and resting at home. I get the heat and sun in the summer and cold and rain in the winter I'm only now (thanks to wonderful people like you) realising thats not such a bad thing. Looking forward to a cold winter !

Interesting! What if your VD receptors aren‘t working properly?

Any source for prescription blue blocking (orange lenses) eyeglasses? Love your channel...

Thoughts on structured water (distilled) vs structured well water (high in sulfate)? Assuming both are subjected to direct sunlight in glass containers. Thank you 😊

GIRL WHO !!?

Where can you get a red light?

BTC is not bitcoin but a forked hijacked version that changed the protocol but kept the ticker, posing as the original all this time. BSV is the only form of bitcoin that operates as the white paper describes and the ability to be adopted globally with capability of hundreds of billions of transactions a second.

Fascinating discussion! Thank you. Your channel is so informative - much appreciated!

What tryptophan supplemts do you recommend?

Does the light need to hit bare skin on the abdomen? Or does it just have to hit the eyes? Thank you! 🙏🏽

How LONG does this "pump" continue after the heart stops???have we buried people alive for centuries🙉

So "surface tension" is actually EZ water...rising against gravity through a hydrophilic tube (wood)...using infrared energy all around, day and night😮

Therefore water fasting is all you need for a time...or perhaps even for ALL time??? Jesus fasted 40 days...as have others..

?????Would love to find info on internal scar tissues such as fibrosis in its various forms inside the body and ways to "massage" internal scarred tissues to restore EZ water and heal this kind of injury...

Hi Carrie, what is the difference between the hypertonic and isotonic minerals you recommend?

I'm so thankful for your Practitioner training. Just wanted to say thanks 😊

Great podcast, Carrie! I've been listening to you, Jack, etc. for years and this one is packed with detailed info in such a concise format. Thank you!

Your content is consistently one of the best in the circadian space all the connections so well explained thank you 🙏🙏

Anyone know where to buy true blue blocker glasses for men?

This sounds a little corny but it's actually the placebo effect in reverse. And we know the placebo effect is real.

fear is used to keep so big pharma can profit

Yes - this is so so important for people to understand ❤️💦

This is such a useful and important message, thanks for posting it

great! thank you

Thanks for the information :-)

GREAT STUFF. Thank you

Wired headphones still conduct radiation. To avoid it, you need to use an air tube headset.

This applies to everyone, not just teens! My sleep score (according to my Oura ring) has gone through the roof when I started following these ideas. My husband (age 70) has many of these health issues and spends hours watching KZbin videos at night. Making these changes in our life is a long slow process but oh so worthwhile. Thank you so much for sharing these ideas.

I love the info but am finding it very overwhelming to do. Especially when I use my phone or computer to learn more, communicate with others about these things etc. totally stressed out about it. Is there someway to simplify. Maybe a way to do phone and computer use that isn’t damaging, as much?
