No sun, no life! Great video! Hope this wakes up many people...
Infrared increases EZ-Water (exclusion Zone Water) in and around our cells! EZ-water is pure cleansing for our system.  And yes, our eyes tell us, when our body has received enough sun! So please no sunglasses, when outside...only to protect eyes when windy and in the snow. And filter glasses to protect from blue light!
Coconut oil and Aloe Vera protects a little bit from sunburn...for those who are not used to direct sun exposure. 
Let common sense come back to humanity...Studies are mostly made from extracted cells outside of the body system...this is not natural and doesn't give true results. 
Back to the roots, back to nature 💪🏽🌞
