The Science of Sleep: Understanding the Importance of Quality Rest for Overall Health
Sleep is a fundamental biological need that plays a crucial role in maintaining our overall health and well-being. It is during sleep that our bodies repair and rejuvenate themselves, allowing us to wake up feeling refreshed and energized.

Non-REM sleep is further broken down into three stages: N1, N2, and N3. Each stage plays a unique role in the restorative process that occurs during sleep.
