Discipline of Sleep Medicine

It is only in the last 50 years that scientists and clinicians have embarked on the systematic study of the biology and disorders of sleep.

Remarkable advances in the neurophysiology of normal sleep and in circadian biology, the discovery of the genes that regulate these biological rhythms, and recognition of the interactions between sleep and almost all other body systems have emanated from diverse disciplines. This has led to the evolution of a new clinical field of Sleep Medicine and a very active research field.
