Performance Criteria and Testing Protocols for Features in Sleep Tracking Consumer Technology Devices and Applications (ANSI/CTA/NSF-2052.3)

Sleep is very important. Good, quality sleep supports healthy brain function and contributes to healing and repair of your heart and blood vessels. Ongoing sleep deficiency can lead to chronic health problems, and can affect how well you think, react, work, learn, and get along with others. Because sleep is so important, consumer technology companies have developed a range of products to help you determine how much sleep you’re getting, and the quality of that sleep. This standard describes events (such as waking up), processes (such as REM sleep) and patterns (such as circadian amplitude), and how to figure out how well a consumer sleep monitoring device determines if a person is asleep and, if so, which sleep stage the person is in.
