In many cases, we have forgotten the basics – we only think of taking our temperature to check for fever, or in some cases of mapping out a menstrual cycle. As you will learn below, taking your temperature at specific times through the day is an extremely useful way to measure how effectively your body is utilizing thyroid hormones, which can be associated with many health condition.
By measuring your temperature, we may uncover a true thyroid disorder, but in other cases it indicates how well you are metabolizing and utilizing the more active thyroid hormone called T3, or triiodothyronine, which is rarely a true thyroid disorder.
Your thyroid hormones are important for your overall wellbeing, influencing your mood, memory, weight, temperature regulation, cardiovascular function, hormone balance, energy level and more. These hormones are central to your wellbeing!
How and when to take your temperature:
It is best to use a glass thermometer. Hold under your tongue for 5 minutes. If this is not available, an auricular (ear) thermometer or digital thermometer are OK substitutions. With the ear thermometer, repeat 3x in each ear and use the highest reading. With a digital thermometer, if possible calibrate with a glass thermometer first. When measuring with a digital thermometer, leave it under your tongue for a full 5 minutes, even if the thermometer beeps much earlier.
Take your first temperature reading 3 hours after waking. Set an alarm and measure three hours later, and then again after another 3 hours.
Women – the best time to take your temperatures is in the follicular phase of your cycle, meaning somewhere between day 7 and 12, counting from day 1 = the first day of heavy menstrual flow.
Take these measurements for 3 days in a week, and average the numbers each day.
