Understanding Sleep Cycles
Sleep is not just rest; your brain goes through different activity patterns. Scientists categorize these into two main types: REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) sleep.
The 5 Stages of Sleep (~90 mins/cycle)
- 1Stage 1: Brain rhythm slows down. Entering light sleep.
- 2Stage 2: Eye movement stops, brain relaxes. Preparing for deep sleep.
- 3Stage 3: Brain waves slow further. Prelude to deep sleep.
- 4Stage 4: The deepest sleep stage. Crucial for physical restoration. Waking up now is very difficult.
- 5Stage 5 (REM): Rapid Eye Movement. Most dreams occur here. The brain processes memories and emotions.
After a cycle ends, the body returns to a light sleep stage. This is the perfect time to wake up!
