How to Take your Basal Body Temperature Accurately

The basal body temperature is the lowest body temperature event within a given 24 hour period. This gradual dip begins in the evening, reaching a low point in the small hours of the morning. Most people take their basal body temperature just before rising; between 5 and 7.30 am.

The average human body temperature is 37°C but will vary throughout the day, the time of the month and from person to person.

Digital Thermometer for Taking Body Temperature
Keeping a record of your basal body temperature is essential if monitoring a thyroid condition or hormonal imbalance. Readings in excess of 37°C in the small hours could indicate an overactive thyroid gland (hyperthyrodism), fever or other metabolic malfunction. A reading that dips beneath 36.5°C could indicate an underactive thyroid (hypothyroidism), adrenal exhaustion, estrogen dominance, hypothermia or an unhealthy diet promoting candida.

Take Your Temperature

In order to keep track of a condition or illness, it is vital to take your body temperature correctly. Consistency and accuracy are the aim.

Highly sensitive digital thermometers are designed only to measure temperatures that fall between 25°C and 45°C. Inexpensive, they can easily be found in the local chemist and are easy to use.

The Digital Thermometer

My thermometer has a digital display and a metallic tip that is placed under the tongue. In fact, the body temperature can be taken in three ways: rectally (the most accurate) orally (almost accurate) or beneath the armpit (the least accurate). Always have separate thermometers for oral and rectal readings. I take my temperature orally, and if done correctly, can be highly accurate.

False Body Temperature Readings

Before taking your temperature, ensure there are no external factors that could affect the reading. Don’t for instance take a reading soon after eating or drinking, as the temperature of the food will affect the result. The reading will be affected if there is a cool draught in the room or if the electric blanket is on. Keep the mouth closed for at least ten minutes before taking the reading so that the enclosure will match the core body temperature.

I am mindful that the thermometer is not in a cold place, as some digital thermometers take only a few seconds before it bleeps and the reading is done. This minimises the chances of the reading being lower than it should.

Here is how I take my basal body temperature.

1 Place the thermometer on a bedside table within easy reach. Have a notebook and pen handy in order to jot down the reading.
2 Plan to take the reading anytime between 5am and 7am before rising. Set the alarm if necessary.
3 Avoid moving too much before taking your temperature. For instance, don’t sit up, talk or shift about, for this will affect the reading. Keep quite still and relaxed.
4 I warm the tip of my thermometer for half a minute or so beneath the armpit for the metallic tip gets quite cold.
5 Once warmed, activate the thermometer until it is reset. Mine shows the symbol Lo.c. Yours might display a different symbol.
6 Remember to keep your mouth closed for a few minutes before popping the metal tip beneath the tongue.
7 Keep still and wait for the beep. Try not to move the tongue around, for this could generate false heat.
8 Wait until the bleep sounds. Most digital thermometers take around ten seconds to complete the reading.
9 I will sometimes take a second reading beneath the opposite side of the tongue. If the two readings differ, I trust the higher reading.
10 Try to take readings on the same time every day in the same way and to keep a record.

Keep the tip clean with mild soapy water after each reading. Don’t immerse in water or expose to extreme temperatures. I keep mine in a plastic container in a shaded position.
