What is differance between night sleep i guess you could call it, example being the 6-7 hrs i get a night and the sleep you get during shoter naps. Is there any differance in the ability to recover during those differant times. I get about 8+ during the school year this year as a senior, only 15.5 credit hrs instead of 21.5 two years ago and only got about 5 hrs a day if I was lucky
