Sleep is one of the most important things a person does each day. It allows the body to rest and to replenish itself so that it is better able to serve its function of living. Yet many people who don't have enough hours in the day to do everything have to cut out sleep before any other activity. This is especially true for teenagers, who most nights are frantically trying to finish writing essays and completing worksheets before the clock strikes twelve, or are busy participating in after school sports that leave them weary and return them home late. Most adolescents need at least eight hours of sleep each night. But the National Sleep Foundation estimates that only 15 percent of teenagers get that much, with 25 percent of teens getting less than seven hours. With adults, this amount of sleep is known to cause countless problems in their everyday life. And as adolescents are biologically driven to sleep longer and later than adults do, the effects of these sleeping patterns are even more disastrous (Carpenter 1). However, the high school education system does not seem to recognize the negative effects that sleep deprivation can have on high schoolers, and continue to have school classes start at an obscene time of morning. Each of us has a specific daily sleep requirement. The average sleep requirement for high school students is well over eight hours. If this amount is not obtained, a sleep debt is created. All lost sleep accumulates progressively as a larger and larger sleep indebtedness (Dement 1). Your sleep debt does not go away or spontaneously decrease.
