Second DIY morning test: basal body temperature
I often have my patients monitor their basal body temperature (BBT) as an indicator of how well their cells are responding to thyroid hormone. Here’s how...
1. Get a reliable digital or mercury-free oral thermometer and place it by your bedside with paper and pen.
2. Check your temperature immediately upon waking after at least 3 hours of sleep and prior to doing anything (including taking a sip of water).
3. Write it down.
4. Do this for 7-10 consecutive days and take the average.
For ladies who are cycling, start on the 1st day of your cycle.
