A Sleep Epidemic: Charles Czeisler at TEDxCambridge 2011 

For awhile I've suspected I've been suffering the detrimental effects of sleep deprivation. For years I've tried to subsist on 6 hours' sleep per night or less. And now I know. Labile emotions. Distractability. Burnout. Depression. Inflammation (knee pain). All me. Wow. Just. WOW.

Great Talk. His study of night shift workers and the effects of light exposure on adaptation to night shift schedules was hugely influential.

Great Talk ! Alot of valuable information - ''if you want to thrive while alive, sleep''

The guy editing the video and the sound didn't get much sleep the night before

Thank you so much! I’m inspiring of going to bed earlier!

videos like this only give me more anxiety. the more I think about my sleeping problems the less I sleep:(((

Really interesting talk, amazing how little views it's got

Thanks for such a great scientific research full speech

If you wanna stay young sleep enough :D

Blah blah blah Heard all before
