Basalt Temperature

Basal temperature: how to measure and how to use data to solve women's problems

Basal temperature (BT) is the temperature measured in a woman’s anus, which reflects fluctuations associated with changes in the tissue reactions of the internal genital organs depending on the production of hormones. Measuring BT allows you to solve several problems related to women's health.

One of the main problems that can be solved by measuring BBT is checking how correctly the ovaries secrete hormones according to the phases of the menstrual cycle. Determining BT also helps to find out whether the egg matures and when this happens, which makes it possible to identify dangerous days for the purpose of protection or, conversely, the possibility of getting pregnant. Also, measuring BT can help determine whether pregnancy has occurred in the event of a delay or unusual menstruation, as well as suspect the presence of endometritis - inflammation of the uterus.

The rules for measuring BT are quite strict. The temperature must be changed at approximately the same time on weekdays and holidays. You should prepare a medical thermometer in advance and place it in close proximity to the bed. Without getting up, without sitting down, without being particularly active in bed, take a thermometer and insert its narrow part into the anus. Lie still for 5 minutes. Remove the thermometer and record the reading in the table.

The BT entry table looks like this:

Day of the monthMarch 15thMarch 16March 1718th of March
Cycle day1234
BT36,836,736,536,4
Special marksHeavy dischargeHeavy dischargeModerate dischargeModerate discharge

This form of recording greatly helps the woman and her doctor to understand the possible causes of infertility, cycle disorders, etc. The special notes column includes any deviations that can affect BT: general illness with fever, diarrhea, intercourse in the evening (and even more so in the morning), drinking alcohol, measuring BT at unusual times, going to bed late (for example, went to bed at 3 o'clock, and measured at 6), taking sleeping pills, etc.

For clarity, it is better to build a graph on a sheet of plain paper in a box. One sheet displays the temperature for the entire cycle (but not for the month!). One cell corresponds to one day. The Y axis is the temperature and the X axis is the days of the cycle. The line connecting all the points shows the temperature change during the cycle.

With a regular menstrual cycle, BT is measured from the first day of menstruation until the next menstruation. In the first phase of the cycle (follicular phase), BT ranges from 36.5-36.8 degrees Celsius, and in the second phase (luteal phase) - 37.0-37.5 degrees Celsius. After ovulation, the temperature rises by 0.2-0.5 degrees Celsius and remains high until the start of the next menstruation.

Changes in BT may be associated with various women's health problems. For example, if BBT in the first phase of the cycle is too high or low, this may be due to thyroid problems or polycystic ovary syndrome. If BT in the second phase of the cycle is too low, this may be due to insufficiency of the corpus luteum. In any case, for an accurate diagnosis you need to contact a specialist.

Measuring BBT can be a useful tool for women who are planning a pregnancy, as well as for those who suffer from menstrual problems or infertility. However, before you start using BT to solve these problems, you need to consult with a specialist who will help you correctly interpret the data and choose the most effective treatment method.
