How Do Basal Body Thermometers Work?
-
-
A basal body thermometer is used for taking your basal body temperature. This is achieved by taking a reading at the lowest temperature your body reaches each day. This temperature reading occurs in the morning, before any activity has taken place. This temperature, if taken on a daily basis, can predict and confirm ovulation, as well as potentially diagnose thyroid problems.

Basal body thermometers differ from regular thermometers in their sensitivity. A regular digital thermometer simply used for fever diagnosis only registers to the first tenth of a degree (98.6). Basal body thermometers, however, register to the hundredth of a degree (98.67). This sensitivity is important, in order to track slight fluctuations or trends in daily temperature readings.

The procedure for measuring and charting basal body temperature using a basal body thermometer is simple. First, keep paper and a pencil on your bedside table, as well as your basal body thermometer. Each morning, take your temperature immediately after waking, moving as little as possible. Moving even a little will raise your body temperature and affect the reading. Keep track of your temperature on a daily basis. This information will be valuable to your doctor if he is working to diagnose thyroid problems or assist you with fertility.
