Measuring body temperature can be useful to do ovulatory cycle tracking, seeing signs of fevers but can also be used as a general measurement of recovery. An increasing number of wearables include temperature sensors to measure the skin temperature as a proxy for core body temperature. | Measuring body temperature can be useful to do ovulatory cycle tracking, seeing signs of fevers but can also be used as a general measurement of recovery.
