basal body temperature

Basal Body Temperature (BBT) is the body's lowest temperature at rest, usually measured right after waking up. It can indicate various physiological changes, particularly in women’s menstrual cycles. For instance, a slight increase in BBT may occur after ovulation due to hormonal changes. Tracking BBT can help in understanding fertility patterns, as women may use it to identify ovulation for conception or natural family planning. It's typically measured using a special thermometer and is most accurate when taken consistently at the same time each day.
