Description : How can you determine the exact amount of sleep you need a night?
Last Answer : answer:Sleep is not the only factor, what you eat, your internal body clock, exercise, what your doing. I go to sleep wake up when I'm ready or have to be somewhere. I only have trouble when working shifts ... at 4 or 5 in the morning. Also I've heard a 10 minute power nap mid day can do wonders.
