One of the easiest and most effective ways to check for thyroid health is the ‘Basal Thermometer Test’ developed by Dr. Broda Barnes, one of the first physicians to recognize the importance of thyroid health when it comes to overall wellness. He wrote the classic book on hypothyroidism called “Hypothyroidism, The Unsuspected Illness” in the 1970’s, and he was of the opinion that numerous health issues including heart disease, cancer, depression, arthritis, diabetes, frequent colds or infections, tonsillitis, ear infections, PMS and other female health issues as well as skin disorders, were all caused by a poorly functioning thyroid. Barnes thought that hypothyroidism affected more than 40% of the American population, which was much higher than most doctors at the time. However, perspectives are changing as hypothyroidism is becoming more and more recognized as a health problem.

The test, which is sometimes called the ‘Barnes Basal Thermometer Test’ is done by placing a thermometer in the armpit for 10 minutes, first thing in the morning. This is important. If you move around and start your day before testing, your results won’t be accurate, so you want to do the test as soon as you wake up, while you’re still in bed. Because temperature for women is a bit lower on the first day of menstruation, Barnes advised women on their periods to avoid testing themselves until their second or third day.
