Why Do We Need to Sleep?

Sleep, generally referring to human sleep, is an indispensable physiological phenomenon for humans. In a person's life, sleep accounts for nearly a third of the time, and its quality is closely related to the health of the human body. This shows how important sleep is for everyone. In a sense, the quality of sleep determines the quality of life. But why should a person sleep? This problem has always been a problem that scientists want to solve thoroughly. Recently, according to the British "New Scientist" magazine, scientists have put forward several statements on the causes of sleep, from the superficial theory of nourishment to complex theories involving memory processing, which have comprehensively discussed human sleep.
