Question: I have taken my temperature (under arm) for six days and the temperatures were: 94.8, 95.8, 96.8, 96.5, 94.9, and 93.3. What do those readings indicate?

Dr. Brownstein's Answer:

Taking your temperature first thing in the morning when you get up gives you what is known as a basal body temperature. The basal body temperature test was popularized by Dr. Broda Barnes in the 1970s.

A normal basal body temperature, under the arm, is between 97.8 and 98.2 degrees Fahrenheit. If you take the basal body temperature orally or on the forehead, add a degree to those numbers.

A low basal body temperature — below 97.8 degrees Fahrenheit — can be a sign that the thyroid is under-functioning. However, a low temperature can also indicate other things, such as low adrenal function.

I use basal body temperature and blood tests to identify, monitor, and treat thyroid and adrenal problems.

Because your temperatures are so low, I suggest that you seek out a healthcare provider
knowledgeable about both basal body temperature tests and hypothyroidism. Once you have your hormonal system balanced, the basal body temperature should return to the normal range.

I have written about the basal body temperature test in my book, Overcoming Thyroid Disorders.
