Sleep is a necessary part of life, and approximately one‐third of human life is spent in the sleep state. Disruption and/or deprivation of sleep may result in potentially adverse effects. These effects can impact one’s health, medical status, psychological state, and even one’s quality of life.

Despite large amounts of research and investigation into the true definition of sleep, the actual purpose of sleep remains one of nature's mysteries and is not fully understood. It is recognized that adequate sleep is needed to maintain alertness, support the immune system, and support memory and learning. The understanding of the physiologic and neurochemical activity needed for the sleep and wake state is now better understood. The complexity of sleep as well as the understanding of sleep requires a basic understanding of physiology, neuroanatomy, neurobiology, and the mechanisms by which these interact.
