Sleep Number's smart bed measures heart rate variability (HRV) using the standard deviation of beat-to-beat measurements, known as SDNN [1]. Even if you didn't sleep in the bed, the HRV data may still be recorded and averaged from previous sessions [3]. To ensure accurate data, follow the provided tips for getting the best insights, such as maintaining a connection to Wi-Fi and ensuring power supply [2][9]. Inaccuracies in sleep tracking have been reported by some users on platforms like Reddit [8]. Sleep Number emphasizes the benefits of monitoring HRV for overall well-being [5][7].
