Our physical, emotional, and brain functions have 24-hour rhythms, also called circadian rhythms. These rhythms keep us in sync with the external world. Circadian rhythm disruption can contribute to sleep problems, diabetes, cognitive impairment, depression, dementia, and other health problems. MyRhythmWatch allows users to assess and track their circadian rhythms. Doing so - understanding your rhythms - is the first step towards improving them and optimizing your health.

For MyRhythmWatch to work, wear an Apple Watch continuously for at least three days and nights. Don’t remove it when you sleep. Only brief periods of watch removal are OK, for example, we recommend taking your watch off and charging it while you bathe; or when for brief periods when you're settling down and won't be active anyway.

Internet and Bluetooth connections are required to sync your data. After getting good data for a minimum of three days, you’ll be able to see your MyRhythmWatch scores. Weaker (smaller) rhythms and unstable (irregular) rhythms have been associated with health problems, and modifying weak/aberrant rhythms may improve wellbeing and health outcomes.

Keep an eye on your rhythms with MyRhythmWatch.
