TAVO detects sleep phases by way of actigraphy, or motion-sensing know-how. Whenever you transfer extra often, you’re doubtless within the lighter sleep stage. Quite the opposite, when motion slows or stops, you’re doubtless in that deep, restorative sleep. Whereas not as exact as EEG or Polysomnography monitoring utilized in sleep labs, actigraphy has proven dependable correlations to sleep phases in numerous research, making it a sensible instrument for client sleep tech.
