Although sleep may seem to be the opposite of exercise, it is an important adjunct to a well-planned exercise program. Sleep is so vital to health that people who are unable to sleep sufficiently (those with insomnia) or who are deprived of sleep experience deterioration in every dimension of their health. Fortunately, exercise is frequently associated with improvement in sleep.
The value of sleep is apparent in a variety of positive changes in the body. Dreaming is thought to play an important role in supporting the emotional dimension of health. Problem-solving scenarios that occur during dreams seem to afford some carryover value in actual coping experiences. A variety of changes in physiological functioning, particularly a deceleration of the cardiovascular system, occur while you sleep. The feeling of being well-rested is an expression of the mental and physiological rejuvenation you feel after a good night's sleep.
The amount of sleep needed varies among people. In fact, for any person, sleep needs vary according to activity level and the overall state of health. As we age, the need for sleep appears to decrease from the six to eight hours young adults require. Elderly people routinely sleep less than they did when they were younger. This decrease may be offset by the short naps older people often take during the day. For all people, however, periods of relaxation, daydreaming, and even an occasional afternoon nap promote electrical activity patterns that help regenerate the mind and body.
