what is basal body temperature
1 answer
Basal body temperature (BBT) is the lowest body temperature measured in a person when they are at complete rest, usually during sleep. It is typically measured using a basal body thermometer, which is more sensitive and accurate than a regular thermometer. BBT is often used in fertility tracking and natural family planning methods, as it can indicate when a woman is ovulating. During ovulation, a woman's BBT rises slightly due to increased levels of progesterone. By tracking BBT over time, patterns and changes in ovulation can be observed.
