Wearable Sleep Measurement

Sleep age translates sleep quality into an age-like comparison against population norms. Current wearables are portrayed as more practical than older EEG headbands because they are less invasive. EEG-based sleep headsets may be more accurate than wearables but are described as cumbersome. A sleep score is limited if it does not translate into personalized guidance. The Oura Ring is described as useful but indirect because it estimates sleep stages rather than measuring EEG directly. Deep sleep is a major part of sleep age because it generally declines with age. Sonic Sleep aims to combine data from common wearables with advanced sleep analysis and coaching algorithms. Float tanks are discussed as tools that may support recovery and sleep.
