What are the stages of sleep?
Hours of sleep are based on:
- your alarm clock
- five or six 90-minute sleep cycles
- 15 minutes to fall asleep
When you fall asleep, your brain and body go through several cycles. Each cycle comprises four distinct phases. The first three stages are part of sleeping with non-rapid eye movement (NREM) and the last stage is the REM sleep (Rapid Eye Movement).
NREM stages were classified as stages 1, 2, 3, 4 and REM. They are now generally classified like this:
- N1 (formerly phase 1): this is the first phase of sleep and the period between waking and falling asleep
- N2 (formerly stage 2): The onset of sleep begins at this stage when you become unaware of your surroundings. The body temperature drops slightly and breathing and heart rate become regular
- N3 (formerly stages 3 and 4): This is the deepest, most restorative sleep stage during which breathing slows, blood pressure drops, muscles relax, hormones are released, healing occurs, and the body is re-energized
- REM: This is the final stage of the sleep cycle. It takes up about 25% of the sleep cycle. This is when your brain is most active and dreams occur. During this phase, your eyes move back and forth rapidly under the lids. REM sleep helps improve your mental and physical performance when you wake up
It takes, on average, about 90 minutes to run each cycle. If you can complete five cycles a night, you would sleep 7,5 hours a night. Six full cycles are about 9 hours of sleep. Ideally, you should wake up at the end of a sleep cycle instead of in the middle of it, to feel more refreshed and energetic.
