[@Malk007]

If everything here holds up long term then LED lights are really worse than incandescent ones. Most of the energy of an incandescent light bulb is in the infrared range (heat radiation) while fluorescent lights and LEDs are much more efficient because the spectrum of light is so focused on the visible range. So we went from Fire to incandescent bulbs to LEDs, each step with less infrared and more visible "useful" light, without realizing we are shutting both melatonin production mechanisms. That 98W difference in energy from a 100W bulb to 2W LED might now be that useless.

I'm a nurse and have long suggested, without the scientific knowledge, that we should have terraces, balconies and parks around our hospitals where patients can either independently or accompanied with staff, go outside and soak up fresh air, sunshine, trees and flowers for their wellbeing. I have been laughed at. But I always knew it would be the best therapy for them.

[@iansamuelson3666]

Totally agree. When dealing with the "ICU psychosis" patients my approach always includes opening windows during the day and avoid any daytime napping.

[@lovetolearn881]

We have a beautiful old hospital in our town located on the river. It is now used mostly for LTC. There are pictures, taken in the old days, of patients outside, enjoying the sun and the view, many pushed out in wheelchairs. Nowadays, never anyone outside. It's not just the availability of the setting, its the impetus to use it. Unfortunately, I fear a major reason patients are not taken outside more is due to risk and the legal repercussions thereof. That is purely speculation on my part though.

Sunshine vitamin or steroid hormone was the most powerful medicine on every living things on earth given by our CREATOR. Sun Exposure The best way to get vitamin D3 is through sun exposure. Go outside and get some sun, especially in the mid-day when it’s the strongest. However, many of us use sun block, which is good for our skin but not so helpful when it comes to the production of vitamin D3. By blocking out the UVA and UVB rays, sun block can interfere the skin’s ability to synthesize vitamin D3. GOD BLESS.

Great information! I was raised on a ranch in Colorado. We went to bed when it got dark and woke up when the sun was about to rise.

My husband went with me to our doctor, who after examination couldn't find anything physically wrong with me. He did not prescribe any meds, just to get some rest. 2 days later he called me back into his surgery. He had another Dr within who also had a patient from Austrailia who apparently had the same problem as me. It all turned out to be LACK of Sunshine..10 days in Greece fixed the problem permanently.

SUMMARY 1. Get as much natural sunlight as you can (direct or indirect), avoiding glass inbetween, as early in AM as possible. 2. Exposure to low level red-light (fire/sunset) at sunset time is advisable. 3. Avoid any type of light exposure after sunset (esp blue light) and especially 1-2 hrs before bed. For circadian rhythms, mood, and antioxidant effects.

The fact that [lack of sun] is correlated with [poorer glucose and lipid metabolism], agrees with the age-old wisdom to ["eat what is in season"]. It has been shown that we can handle fruits (e.g. sugars) better in the summer, and there are risks to eating high sugar in winter -- but less risk in summer (apparently) -- since sunlight in summer helps you digest the fruit. (sun helps glucose metabolism). I hope this is of interest to some. peace.

My 30 year battle with insomnia ended 2 years ago. I found a sleep doctor who knew what my problem was. I would lay awake in bed unable to fall asleep no matter how tired I was. Though I was not stressed or worrying my mind would race. I was always told it was anxiety but it was not. I was not anxious and even when all was well in my life this problem would not go away. One hour before the alarm would go off all of a sudden I could sleep like a baby. Well one hour is not enough to get by on but I got used to it. Turns out it was because I was staying up past the point of getting my second wind. Second wind is a shot of adrenaline that is intended to keep our vitals going past the point of exhaustion. The answer was go to bed the minute I got sleepy and it worked. It took a few weeks and I was going to bed stupid early some nights but for the last 2 years I have slept pretty much every night uninterrupted. I don't even wake up in the middle of the night to pee anymore. The second thing my doctor told me was no blue light 2 hours before bed. I used blue blocking glasses but I did not really like wearing them so I just use Windows blue blocking filter in my TV and my body starts producing the melatonin I need to sleep. I put my screen into night mode set to 100 percent. It works. I can even fall asleep with the TV on and sleep like a baby as there is no blue light. I sleep best in complete darkness but this is actually very close. Getting in tune with my bodies natural rhythm has changed so much. I don't know how I got by without sleeping for so many years.

He responded "No, you can't take babies out in the sunshine for the first 6 months of their lives!" So about a week later my nephew was in the hospital, getting *artificial* sunlight therapy for jaundice.

Hi, Bernadette. I have been trying to tell people there is no such thing as death for close to 60 years. I hear the woo woo words a lot from people that don't research. Maybe you would like to read about the info I have found. I had a NDE or near-death experience as a child. I knew that there was no such thing as death then because of my experiences. I tried to tell everyone this, but I was harshly ostracized for many years. Those energy and light beings that I felt around me pointed me to books. None of them are fiction. My favorite has been the book HANDS OF LIGHT written by the physicist Barbara Brennan. She wrote that we are eternal holograms and eternal electrical energy fields. That is because we all consist of 7 billion billion billion atoms, each one an electrical energy field. So why wouldn't we be connected to the sun? We need charging up just like a battery. After all, atoms spin as positive and negative poles. You can see in this book what we look like as total light. One diagram shows quarks spinning us into motion, beaming outwards intersecting all other forms of light. Gell-Mann won a Nobel prize for theorizing quarks. Quarks must have been important for a reason. They are bursting forth spinning billions of times a second as 3 points of light forming protons and neutrons. These last words come from the book THE QUANTUM WORLD written by the physicist Kenneth Ford. I theorize these quarks are bursting forth from the sun. As you can see, these quarks are spinning as 100% light as they create atoms which create us. I think that the people that invented covid knew this when they wanted the beaches clear of people and everyone in their homes. You DID know there is a genocide agenda going on, right? Dr. David Martin is a PhD that works with patents and their relationships to weapons. He says at rumble.com that those covid patents are illegal and that those vaccines are actually weapons built as computer generated chimeras. Those weapons they made up the word covid for are meant to kill billions of people. Martin said fauci has been a racketeer for 30 years. I have read for many years about this genocide plan. People from at least the 1930s have thought about how to rid the planet of so many people. These oligarchs think they want the planet to themselves because we are ruining it. BUT, they are the ones that have dumped all those chemicals into the air and water and crops AND vaccines. Because of these pompous cartels that think they know everything there is to know, billions of people have taken those weaponized vaccines. Since covid doesn't exist, then it is these weapons "killing" people. But never fear. We can't die because we are constantly being created. Quarks are always constantly bursting forth creating everything everywhere. In that HANDS OF LIGHT book are diagrams of what we look like being created. Those quarks spinning so fast build us they slow down into vortexes called chakras. DNA spins. Just like vaccines have to be built, the lie of covid had to be built. Batteries have to be built and WE have to be built. Those super-fast spinning quarks and atoms determine that everything everywhere is being built on a constant basis. This existence is an electrical energy field. The energy within this existence has to be channeled into the electricity we have and the cell phones and TVs and wifi and us. Everything everywhere consists of those electrical energy fields called atoms. How else are we going to heal?

Sunshine vitamin or steroid hormone was the most powerful medicine on every living things on earth given by our CREATOR. Sun Exposure The best way to get vitamin D3 is through sun exposure. Go outside and get some sun, especially in the mid-day when it’s the strongest. However, many of us use sun block, which is good for our skin but not so helpful when it comes to the production of vitamin D3.

Great job on the subjects covered. As a 66 year old who gets many hours of sun each day but has no wrinkles or damage, who walks barefoot or in leather to take in the negative ions and IR of Earth, I can attest to how this has changed my life and body compared to years ago when I seldom saw sun, never walked barefoot, and had a crappy diet. No one knew anything it seems 40 years ago but it has been a fun ride learning and getting ready for my prime years, 66-78 for those that honor their vessels and celebrate life each night and day. Hurrah for your getting this out to us who are hungry for such proofs of what milleniums past have written and taught us. From acupuncture and light, sound, and the invisible forces, we have much yet to learn and understand but this sure makes it easier hearing your explanation of the newest proofs.

I think nursing/care accommodations for seniors would benefit by exposing patients to natural sunlight daily. We used to wheel patients out into the sunroom attached to each ward.

Great to know that melatonin is such an important antioxidant, right along with glutathione. As ROS increase under stresses, these antioxidants are critical. And, this points out how the toxic metal lead can reduce available glutathione by up to 60%, suggesting how the lead body burden we all have accumulated by a hundred to 1000 x's prehistoric bone levels, can come out of storage when the body needs more calcium, to once again damage many physiologic pathways such as glutathione levels, and leave us more vulnerable as another often overlooked 'co-morbidity'.

Adding melatonin to my routine has really helped and now I can actually get up to eight hours many nights (usually between six and seven).

Lots of gems in this discussion. I’ve read that melatonin production drops off as we age. Should older people take supplements at night? What happens if younger people take melatonin? Is there a difference in skin colour and absorption of IR? What a shame that most elderly in nursing homes don’t get to sit in the sun everyday, and patients in ICU don’t get periods of darkness. Nice green eyes🙂

I’m not a doctor - just some thoughts. If our body were to produce less of chemical/hormone as we age I assume it’d be to offset the workload created by its presence. Functions such as metabolism cost the organs energy. The body is constantly trying to preserve energy and optimize itself. Adding external chemicals into the mix may add an extra workload to organs such as the liver which is what the body was trying to offset in the first place. These mechanisms are beyond the scope of my knowledge and I may not be seeing the full picture here. Just a line of thinking that seems logical, at least in my mind.

@@hellohello-rd1vr Many things decline as we age, including the body’s ability to repair itself. This is not to conserve energy. It’s a symptom of aging. It’s why we eventually die.

Some insurances approve a light to help aid in this for serious medical diagnosis. Severe cases

[@MrsSlocombesPuddyCat]

I have read that the darker your skin, the more trouble you have absorbing light and sun.

This is beautiful. Thank you for sharing!

[@EvaSawicka]

I love Dr. Seheult knowledge. Truly amazing!

[@aztrails1]

I have been enjoying Dr. Seheualt's videos on sleep and vitamin D.. He is a remarkably good communicator. Thank you.

[@simplycynth5.0]

Dr. Seheult, what are your thoughts on the daily use of sunscreens for skin cancer prevention and prevention of premature or excessive skin aging? It seems like most dermatologists and beauty experts recommend them as absolutely necessary. I would love to hear your thoughts on this subject.

[@rogerseheult1312]

These products will not affect the beneficial aspects of infrared radiation.

[@DSJALLDAY]

As a SPF formulator the industry really harps on the risk of damage and photo-aging from beyond the UV spectrum that we rate our sunscreens for. Suffice to say, it’s a tight rope to avoid early signs of aging or skin cancer and still keeping the body doing what it was designed to do with regular sun exposure.

[@sunvavachi]

It's definitely a necessity. As sunscreens have ingredients to help combat UV radiation like zinc oxide and other derivatives. :) So along with enough sources for light skin care matters to prevent skin conditions and cancer as well.

[@DJRenee]

I use coconut oil as a sunblock

[@CharGC123]

I am very curious about this also. For starters, it seems to me that if just the sunscreen washing off of swimmers bodies is killing our coral reefs, it certainly can't be a great idea to slather it all over ourselves! As soon as they remove one offending chemical, they find others. Evolutionary biology has developed over the millennia for our optimal existence and adaptability in tune with our environment, and somehow I can't see the necessity of using the ubiquitous array of sunscreens and other man made products to improve on it! I realize we have some extenuating issues we may not have had before, but I still prefer common sense precautions to sun exposure over intentionally exposing my largest organ... my skin... to a cocktail of questionable industrial chemicals!

This has to be the best video video on light and how IR benefits the mitochondria. There are other vids on the subject but this one blows the other away.

[@baileyetcetera8296]

This is a master class! Thank you.

[@vne5195]

What a fantastic video. Thank you so much! While my family ignored the shutdowns, we went fishing and hiking in the forest while we couldn't "work" or attend school. Though we were often alone (as a family) while we enjoyed the outdoors, we have many nice memories. We've had fewer illnesses then in any other years of our lives. Perhaps shutdowns really do work (when properly disregarded). Peace~

[@moperson1]

Ignored the shutdown? You and yours help extend the pandemic for the rest of us. Gee, thanks.

[@nancylourose]

@@moperson1 they were alone in a forest. How does that affect others?

[@Kim-ek7xy]

This was absolutely fascinating! I'm going to make it a habit now to get more early morning sunlight, take my dogs for a walk, do my gardening. Love this channel!

[@Medcram]

Good to hear, thank you!

[@franciscoballesteros2059]

Sunshine vitamin or steroid hormone was the most powerful medicine on every living things on earth given by our CREATOR. Sun Exposure The best way to get vitamin D3 is through sun exposure. Go outside and get some sun, especially in the mid-day when it’s the strongest. However, many of us use sun block, which is good for our skin but not so helpful when it comes to the production of vitamin D3. By blocking out the UVA and UVB rays, sun block can interfere the skin’s ability to synthesize vitamin D3. GOD BLESS.

[@willbrink]

Another great vid and why I recommend this channel to followers. I left the NE for FL as each winter became less and less tolerable and no light boxes really helped.

[@johnnyyu7439]

Well done Dr Seheult, I am a big fan. This is what practicing Medicine to benefit humanity about.

[@eastwestRD]

This was the most thorough presentation on sunlight and health I have ever seen. Fanstastic! Thank you to you both. It was long, but really worth it. I think Dr. Seheult needs to add functional medicine to his specialties.

[@delaneyondreams]

It was long, A N D we loved it! Thank you for your patience in teaching us, for your organization, repetition ( which I usually detest), your depth, and clarity. I hope. you will make more LONG videos on more intermediate and advanced levels of this vital topic!

[@delaneyondreams]

@@Medcram , As you can see in my two comments below, Dr. Seheult, I just HAD to pose some questions. Since then (3 weeks ago), I have more. Do you have time to read a list of practical questions the answers to which would help us all enact your suggestions? If so, LMK where I could address them. We could clarify and show people how to manage changing habits in the face of emotional, physical, and social resistance. This was a good start, now we need more info and ideas as to how to enact your suggestions. This truly is the Asbestos Moment. How to Modify Your Schedule to synch it with your SCN! Catchy, no?

I went hiking with my son, 4 nights, 3 days walking. Outside all day, I'll say when it got dark I seriously ready to sleep. I got locked in to nature's circadian rhythm very quickly, exercise and natural light only.... and wow I slept great!
