Sleep is the blessing of god that helps a person to keep off from all his problems both physical and mental for a period. Just think of a day when everyone is at sleep and you alone are awake and there is nothing to do. People who get normal sleeps most of the time will not realise the importance of sleep as much as a person who is deprived of.

Scientists still do not fully understand what makes us sleep but certain sleep centres have been found in the brain which is thought to act as a sort of body clock controlling the timing of rest and wakefulness. Natural chemical in the body and diet plays a part to promote sleep.
