How much sleep does an average person should get? I usually get 6-7 hours a day, but only with a clock alarm. I go at 12pm and wake-up at 6:40 but I used to go to sleep at 2am and wake up at 5:45. With my sleeping is like this, when I sleep more than 8 hours, then I lack any energy for doing anything in a day. For example, at summer, I've been waking up, past 1pm and had absolutely no desire for doing anything but lying whole day whatsoever. If I didn't set up my clock alarm, I would sleep more than 8 hours. <- always! When I've been waking up at 5:45, then I found sleeping 4-5 hours most efficient out of all. However I felt complitely terrible right when I woke up. I was like zombie from the Resident Evil movie. How much sleep do you usually get?
