Once you fall asleep, I’ve long advocated that 7.5 or 9 hours is the perfect number of hours to sleep, give or take a few minutes depending on your 90 minute REM cycles.
If you are doing serious training, that number should be 9 hours PLUS the time to fall asleep. I read somewhere Paula Radcliff sleeps 11 hours a day (or at least “in bed” 11 hours a night)
But I’ll bet most Americans sleep less than that. And to boot, they are using alarm clocks to wake you up in the middle of deep REM sleep, making you feel worse.
Earlier this year, I posted a nice Infographic on Sleep Deprivation and Testosterone Levels and I discussed sleep in How To Increase Natural Testosterone.
Here is another Infographic on why Sleep is Awesome.
(More articles on REM sleep can be found here: REM Sleep 2011, REM Sleep 2009, and REM Sleep 2007)
The Effects of Sleep Deprivation
If you’re like the average American adult, chances are that you sleep a lot less than you would like to.

Great >_< Thanks.. It would help my sprinting.
Great infographic. Some really interesting facts on that one for sure… Sleeping really is one of those things where you need to get it together and just get done what needs to be done. To dim the lights at 10pm really is not that difficult, it’s just all about making it a habit. Thanks for sharing!
