Did you know your thyroid hormones regulate your body temperature? When your core body temperature is consistently low it’s a strong signal your thyroid is working below par.


What is an ideal body temperature?


Your body works best within a very narrow temperature range. Enzymes, hormones, vitamins and minerals work best between 36.5 – 37.5 degrees Celsius (97.8 – 99.8 degrees Fahrenheit).


A colder body temperature can indicate you are experiencing reduced metabolic activity due to low thyroid hormone activity.

Testing your basal body temperature is therefore a simple way to assess your current thyroid health.


How to do your own basal temperature testing


Basal temperature testing is a simple, at home test. All that is required is a good quality thermometer. Here is what you need to do;


Place a digital thermometer by your bed before going to sleep at night. This will make it easy to grab in the morning.


As soon as you wake up and before you get out of bed place the thermometer in your mouth. It is important to make as little movement as possible. Lying and resting with your eyes closed works well.


Read and record the temperature and date. Do not get up until you have this temperature result. When you get up and move around your temperature naturally rises.


Perform this test on at least five mornings. If possible do this test around the same time each day.


Note: Menstruating women should avoid doing this test around the middle of their cycle as body temperature naturally rises at ovulation. Men and non-menstruating women can perform the test at any time.

Even a small drop in body temperature is significant


There is a strong correlation between your waking, or ‘basal temperature’ and how well your thyroid is functioning.


Under normal conditions the body is able to maintain a fairly steady core body temperature of 37 degrees Celsius (98.6 degrees Fahrenheit). If your temperature appears to be consistently below 37 degrees Celsius (or 98.6 Fahrenheit) you should discuss your findings with your healthcare practitioner.


Basal temperature testing is not usually used as a stand-alone diagnostic tool. Your basal temperature is considered along with other signs and symptoms of an underactive thyroid.


To provide some perspective on how significant even small changes in body temperature can be let’s take a look at two potentially dangerous situations.


Hyperthermia occurs when the body’s core temperature gets too high due to fever, vigorous exercise or heat stress.  When the temperature climbs above 40 degrees Celsius (104 degrees Fahrenheit) it is considered life-threatening


Conversely, mild hypothermia occurs when the core temperature drops below 35 degrees Celsius (95 degrees Fahrenheit). In severe hypothermia, the core body temperature drops to 32 degrees Celsius (89.6 degrees Fahrenheit) or lower.


As the core body temperature cools the vital organs produce less heat which in essence causes a protective ‘shut down’ of the body to preserve heat and protect the brain.


Low body temperature slows brain activity, breathing, and heart rate. Many hypothyroid sufferers would be familiar with these symptoms!
