Tag: REM cycle function

Sleep, one of the most fundamental physiological behaviors, remains one of the most intricately regulated and least understood biological states. For many, the need to define sleep seems unnecessary—after all, it is a daily experience. Yet from a neurological and biochemical perspective, the scientific name for sleep is more than just "rest"; it is a highly orchestrated phenomenon shaped by a complex interplay of neural signals and chemical messengers. This article delves deep into the chemistry behind sleeping, explaining how the brain's natural sleep chemicals regulate the sleep-wake cycle and how these neurochemical processes influence cognitive health and longevity. In doing so, we uncover how the chemical architecture of human sleep holds the key not only to rest and repair but also to brain health and extended life.
