Top Stories sleep
Hi Lifehacker, Sometimes I wake up earlier than my morning alarm. This can be as little as five minutes but sometime as much as an hour. I don’t feel like I get enough sleep on the whole but once I’m awake I can’t help checking the clock. My question is: at what point is it no longer worth me trying to get back to sleep? Is there a point that I might as well just get out of bed?
It seems like a question that’s as old as time itself: “How much sleep do I really need?” The non-profit National Sleep Foundation and a panel of 18 prominent medical scientists and researchers reviewed over 300 sleep studies to try and finally answer it.
Dear Lifehacker, I hear a high metabolism is good for losing weight and keeping healthy, so I try to stay active. However, I love my afternoon naps! Sometimes I’m just tired, but they keep me productive. Sleeping slows your metabolism down though. Am I undoing all my good work?
