Is Sleep Tracking on Smart Bands Really Accurate?
Sleep tracking on smart bands uses sensors to monitor movement and heart rate, offering insights into sleep patterns. While they can estimate sleep stages like REM and deep sleep, their accuracy is limited compared to medical-grade devices. Factors like wear tightness and environmental conditions can affect readings, and discrepancies may occur between reported data and personal sleep quality. Thus, smart bands provide a useful overview but may not capture all sleep aspects accurately.
