While we sleep, our brains and bodies restore themselves. Each sleep stage serves a unique purpose and is essential for waking up feeling refreshed.
- Awake: It’s normal to spend some time awake during the night, including while falling asleep and during brief periods of waking. This time is represented as "Awake" in your sleep charts.
- REM (Rapid Eye Movement): REM sleep is known for its role in memory consolidation, brain refreshment, and dreaming. It’s essential for cognitive function and emotional health.
- Core Sleep: Often referred to as light sleep, Core sleep is where most of your sleep time occurs. During this stage, muscle activity decreases, and body temperature drops. Core sleep is crucial for overall health and restfulness.
- Deep Sleep: Also known as slow-wave sleep, this stage is where your body focuses on physical repair and the release of growth hormones. It primarily occurs in longer periods during the first half of the night and is vital for physical recovery. You’re deeply relaxed, making it difficult to wake up from this stage.
