Sleep is not just a simple absence of wakefulness.

The amount and quality of sleep may significantly affect the health of the person. For example, inadequate sleep is detrimental to the process of learning and memory stabilization. Both insufficient and prolonged sleep are associated with increased risk for developing metabolic syndrome. The basic physiological determinants and the health effects of sleep will be presented in detail in Chapter 10.

Finally, the role of stress on human health has been studied extensively during the last three decades. Stress is caused by various life events; these events don't have to be negative to cause stress. For example, making wedding preparations is a good thing but nevertheless a source of stress. Routine daily activities can also induce stress. However, people's responses to stressors vary greatly and depend mainly on the perception of the specific event; i.e., an event that may cause stress to one person may have no effect on another person. It has been shown that even minor stressful events constitute a substantial source of stress, resulting in deterioration of both mental and physical health. When the adverse effects of daily difficulties and inconveniences congregate, they can aggravate susceptibility to several diseases and undermine overall well‐being. Chapter 11 presents the effects of social life and stress on the prevention and treatment of major diseases.
