BED HAVING CONTROLLER FOR TRACKING SLEEPER HEART RATE VARIABLITY

Abstract:

A bed has a mattress. A sensor senses cardiac activity of a user of the bed and sends, to computing hardware, data messages recording the sensed cardiac activity of the user. Computing hardware performs operations that include receiving the data messages from the sensor; determining, from the data messages, a heart-rate variability metric for the user at a plurality of time-points in a plurality of single sleep session; calculating, for a given sleep session using the heart-rate variability metric for the user for the given sleep session, a recovery-metric that reflects the degree of cardiac restoration that the sleep session has provided to the user; and displaying the recovery-metric in a user interface.
