More Thyroid Tips: Track Your Basal Body Temp

How to Monitor Your Basal Body Temperature


Blood tests may not be sensitive enough to detect milder forms of hypo- thyroidism. Monitoring your body’s basal (resting) temperature is often used to identify a thyroid hormone deficiency.


Here is how to track your basal temperature accurately:

  1. Get a Basal Body Thermometer and place it where you can reach it without getting out of bed.
    1. In the morning, before you get out of bed, take your temperature.


  • Keep a record of your temperature for at least ten days. (Women should do this during the first two weeks of the menstrual cycle, as their basal temperature may rise during the latter half.)


Normal basal body temperatures fall between 96° F and 98° F. If your basal temperature is consistently low in that range, you could be mildly hypothyroid.
