Beyond fertility, BBT can serve as an indicator of . Consistently low basal temperatures (below 97.0°F) may sometimes correlate with hypothyroidism or a slow metabolic rate, as the body’s "furnace" isn't generating standard resting heat. Limitations and Accuracy
The accuracy of BBT tracking depends heavily on consistency. Because the margin of change is so small, various factors can "mask" the true basal reading. These include: basal temperature
BBT charting is most commonly used for . By recording daily temperatures with a sensitive basal thermometer (which measures to the hundredth of a degree), individuals can identify when ovulation has occurred. It is important to note that BBT is a retrospective tool; the temperature rise happens after ovulation, meaning it confirms the event rather than predicting it in real-time. Beyond fertility, BBT can serve as an indicator of
Sustained higher temperatures until the next period begins. Because the margin of change is so small,
