Evening light exposure shifts the body's clock later and is associated with poorer mental health outcomes.

“Pm light shifts you later and is associated with worse mental health outcomes.”

“well there was a recent paper published in the journal Nature mental health an excellent Journal focusing on not just the positive effects of viewing light at those times of day and indeed throughout the day but also the independent and positive effects of being in darkness for 6 to 8 hours every night that's right not only is light during the day correlated with significantly improved mental health outcomes but Darkness at night that is avoiding lights not just bright lights but lights for up to eight hours at certain periods of your 24-hour circadian cycle has been correlated with improved mental health outcomes and indeed has been shown to significantly offset certain negative mental health outcomes this is a spectacular study again it involved a enormous number of research subjects more than 85,000 research subjects and it touches on a large number of actionable protocols that I've distilled down to just one or two things that all of us can easily do to improve our mood and mental health on a consistent basis”

“first I present a paper that is about how light exposure during the morning and daytime as well as dark exposure at night each have independent and positive effects on Mental Health as well as the ability to reduce the symptoms of many different mental health disorders”
