How Much Deep, Light, and REM Sleep Does a Person Need?
Sleep is a complex process crucial to overall health and well-being. It’s more than just closing your eyes and drifting off—it’s an active state where the brain and body perform various restorative tasks. While the full purpose of sleep remains a subject of ongoing study, there are several prominent theories that explain its importance. These include the Inactivity theory, Energy Conservation theory, Restoration theory, and Brain Plasticity theory, each offering insights into why sleep is essential for both mind and body.
