Not sure if this thread belongs here, but sleep is a part of staying healthy, so I'm gonna roll with it. Pohlyphasic sleep is essentially short naps throughout the day instead of one long rest at night. The extreme version is where you take twenty minute naps every four hours (2 hours of sleep total in 24hrs), and allegedly thats all you need. I'm thinking it might be useful while traveling around sheisty areas or if you really need to stay up for some reason. If anyone has tried this, please tell me how it worked out for you.
