Abstract
The circadian rhythm metric acrophases from consumer wearables significantly correlated with traditional assessment methods (r = 0.96, r = 0.87, r = 0.79; all p < 0.001).
- Circadian rhythms are biological patterns that follow a 24-hour cycle and can affect health.
- Current monitoring methods for circadian rhythms are often invasive or subjective, limiting their use outside laboratories.
- In a two-week study with 36 participants, data were collected using a smartwatch, Actigraph, and core body temperature sensor.
- Acrophases from commercial wearables showed a strong correlation with acrophases derived from traditional measures.
- Consumer sensor data significantly predicted individual chronotypes, indicating potential for real-time monitoring.
