Validation of the Mobile App–Recorded Circadian Rhythm by a Digital Footprint

Validation of the Mobile App–Recorded Circadian Rhythm by a Digital Footprint

This regular adaptation is referred to as the circadian rhythm. Since the 1970s, scientists have investigated the molecular mechanisms controlling the circadian rhythm [1-7].
