Importance of sleeping in a dark room

[ThomasBart]

Sleeping in a fully black and cold room will change your life. Many already know this but for those who dont, this will make a huge impact. I just fully blacked out my room a week ago and im sleeping 10 hours a night and wake up well rested and less facially bloated.
