How to take your basal body temperature

Your body temperature is a reflection of your metabolic rate, governed by the thyroid gland. Imbalances in thyroid hormone production reveal themselves in changes in basal body temperature. Normal basal body temperature is 98.6°. If your basal body temperature is chronically low, it can be a sign of low thyroid function or Wilson’s syndrome. If it is chronically elevated, you could be pregnant or have a hyperactive thyroid gland (Graves disease). A visit to a physician can confirm either concern. You will need a thermometer to perform this test.

1. Before bed, shake down a thermometer to below 95°F and put it in a safe place for the night.

2. On rising, place the thermometer in your armpit for 10 minutes. Try to lie down and stay still while performing the test.

3. After 10 minutes, read your temperature and note it with the day’s date.

4. Repeat your temperature test for 3-5 consecutive mornings.
