Your body goes through several sleep cycles, including REM (rapid eye movement) and non-REM sleep, and each one is essential for different recovery processes in your body. While you sleep, your body repairs itself, consolidates memories and processes information from the day. Without enough sleep, you don't just feel tired and irritable, it can also have serious long-term effects on your health.
