I wondered that if our body is wrapped up in just clothes while we are awake (except of course when we leave our mother's secure womb, and while we take a shower :)), so why do we feel the need for clothes "and" a blanket while we are in slumber.
The answer... is body temperature... the link between body temperature and our body.
Not everybody realizes that our body temperature works and ticks like an internal clock controlling our sleeping cycles. Body temperature also controls the metabolism, circulation and other involuntary activities our body undertakes. Whenever you put big physical demands on your body your body temperature will rise above the norm. As a response to any intensive physical activity, the body temperature drops for a while as soon as you stop the activity. This is when you feel sleepy, and you feel the need for a blanket since your body temperature is below your regular body temperature during the day.
Though it might not be a neccessity, but most of definitely use a sheet during sleep time. I definitely do :)
