Basal body temperature (BBT) is the lowest body temperature reached during sleep. It’s typically measured first thing in the morning, before getting out of bed or doing any activity. BBT can be used to track ovulation, which is important for women who are trying to conceive.
There are a few different ways to check basal body temperature. The most common method is to use a basal body thermometer. These thermometers are designed to measure small changes in body temperature, and they’re more accurate than regular thermometers. You can also check your BBT using a digital thermometer or a fertility monitor.
