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.

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. We never used an alarm clock because our bodies just "knew" when it was time. To this day, I never set an alarm clock. my body just knows. Pushing 70 and my mom, who is still alive is 94. I wake up because my energy tells me it is time. I make coffee, and let the dogs out and feed the chickens. life is great. trust your body. I don't use internet or cell phone after 6 pm, ( I am an old fart), and I just read a book at night to relax.. (remember books? )

I'm 66 yrs of age. I remember as child I would see the elderly sitting in their yards or in front of their homes in their bathing suits soaking up as much sun as possible. So now I do the same on my roof top porch. I notice loads of increased energy. As usual, the Elders know best!

My sister was in a Sanatorium for 11 years. 1:56:09 They implemented this 1:56:09 Light and sun method then as well. Patience were wheeled outside summer and winter for sun exposure and in the winter for cold exposure. They were left outside for several hours each day. My sister had TB and is still alive today and 84 years old. I believe without sun expire and sufficient light our bodies can not sustain a healthy life. Thank you

This suggests that keeping the elderly and sick indoors all the time is a harmful practice.

Ex- night shift nurse here. It literally took me 4 years to get my circadian cycle normalized. The damage working night shift did to my body was NOT worth the extra $8 bucks am hour. Eff it!

At age 22 I moved from sunny South Africa to Ireland. After 10 months I started getting weird thoughts, became afraid of driving or going out on my own. 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. Never had it again!

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.

I got virus last week and have been spending most of the daylight hours outside laying out by my pool soaking in the sun. Feeling good. I had done some research on this in the past so thank you for sharing info with the masses. Even the bible shares this wisdom: " Light is sweet, and it pleases the eyes to see the sun. " ~ Ecclesiastes 11:7

Health bloggers such as Andrew Huberman and Tim Ferris have noted that 5-7 minutes of exercise during facial sun exposure resets melatonin cycles to improve sleep. I've found this to be extremely helpful. I just stand in my backyard and do deep knee bends and arm extension/retraction for 6 minutes while listening to lectures like this on my phone

I am the caregiver for my dad and every morning we have light therapy. My dad always says it makes him feel good.

One of my aunts born in the 1930 had parts of both of her lungs removed as a small child as she had Bronchiectasis and this was the tratment at the time. In her recovery period she was put in a bed outside the whole year with people who were recovering from TB. Her mother was told she would only live till she was ten she died in her seventies.

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.

I've spent most of my working and leisure life outdoors...in the sun, with no sunscreen. The trick is to start getting sun in the early spring, so that you'll already have a tan to protect you from getting burned when the sun is stronger in summer.

So that's why I love sitting by thefireplaces, it is so calming and makes me feel sleepy.

This is such an important video. I’ve saved it and intend to listen to it over and over and then make some pretty big changes in my sleep hygiene. I’m really undisciplined and it’s important to learn how badly I’m hurting myself!

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.

This is one of the most interesting and profound medical talks I've ever seen in my life. And I've been working in the medical field myself for 44 years. Excellent job!!!
