Definition:

Your basal body temperature is your body’s temperature at rest. To get an accurate measure, your temperature must be taken in the early morning, before getting up or moving around. (Sitting up and walking around increases your body’s temperature slightly.)

Charting your basal body temperature is a way to track ovulation. After ovulation occurs, most women notice a sustained increase in their basal body temperature.
