Detailed explanation-1: -Sleep occurs in five stages: wake, N1, N2, N3, and REM.
Detailed explanation-2: -The four stages of sleep fall into two categories. The first three stages are considered non-rapid eye movement sleep (NREM), while the fourth and final stage is rapid eye movement (REM).
Detailed explanation-3: -Stage 4: REM sleep In REM sleep, your brain waves and eye movements increase. Your heart rate and breathing also speed up. Dreaming often happens during REM sleep. Your brain also processes information during this stage, making it important for learning and memory.
Detailed explanation-4: -As your body progresses through the four stages of the sleep cycle-stages 1 through 3 (non-rapid eye movement, or NREM) and stage 4 (rapid eye movement, or REM), it transitions through different biological processes that affect your temperature, breathing, cells, and muscles.
Detailed explanation-5: -In general, each cycle moves sequentially through each of the 4 stages of sleep: wake, light sleep, deep sleep, REM, and repeat. Cycles earlier in the night tend to have more deep sleep while later cycles have a higher proportion of REM. By the final cycle, your body may even choose to skip deep sleep altogether.
