Abstract

Sleep is crucial for the proper functioning of bodily systems and for cognitive and emotional processing. Evidence indicates that sleep is vital for health, well-being, mood, and performance. Consumer sleep technologies (CSTs), such as multisensory wearable devices, have brought attention to sleep and there is growing interest in using CSTs in research and clinical applications. This article reviews how CSTs can process information about sleep, physiology, and environment. The growing number of sensors in wearable devices and the meaning of the data collected are reviewed. CSTs have the potential to provide opportunities to measure sleep and sleep-related physiology on a large scale.

Keywords: Consumer sleep technology; Health; Performance; Sensors; Wearables.

Simulation of hypothetical sleep data for an individual over time. In the graph, the TRUE day-to-day variation in WASO, a main parameter of interest in sleep research, is provided in red. In gray, the hypothetical WASO obtained from CSTs is displayed by accounting for the randomly generated biases (distance between TRUE WASO and CST-derived WASO), in blue. The level of concordance between TRUE WASO and CSTs WASO changes over time.
