Sleep deprivation, or ‘sleep starvation’ in some circles, is the condition in which the body does not get to have the kind of rest it needs, for either a long or brief period of time. When an individual is asleep, the body can relax and replenish lost energy. If the body isn’t obtaining enough rest to recharge the batteries, then it is time to get worried. The average adult requires between six and eight hours of sleep every day. However, that is not always achievable, what with the busy schedules many people have to follow.
