Sleep Disturbances
events per night
Physical movement detected during sleep, including snoring, arm movement, leg movement and kicks. Reflects sleep fragmentation due to restlessness rather than respiratory events.
Typical optimal range 0 events - 15 events
Population median 18 events
Key factors
- Stress and anxiety
- Caffeine timing
- Magnesium deficiency and muscle tension
What affects this metric
- Restless legs, cramps, and pain increase movement during sleep.
- Caffeine late in the day raises restlessness even when you fall asleep normally.
- Alcohol increases movement and snoring during sleep.
- A warm room and heavy bedding raise restlessness.
- Late intense exercise and pain increase movement.
- Sharing a bed with a partner or pet raises detected disturbance.
