You need to sleep for more than 6-8 hours, wake up in the morning, without getting up, eating water or talking, take a pre-dumped mercury column thermometer, hold it under your tongue for 5 minutes, and then record the degrees on the thermometer. Take a cycle without interruption (that is, from the first day of your period to the day before your next period). Connect each point with a line to make your own temperature curve. Generally, during the first half of the menstrual cycle, the body temperature is at a low level, most people do not exceed 36.5, which is called the low temperature period. After ovulation during the intermenstrual period, the body temperature rises rapidly by 0.3 to 0.5 degrees within 3 days, which is called the high temperature period. The high temperature period lasts until the day before or on the day of the next menstrual period, when the body temperature drops abruptly and then enters a new cycle. Frequently asked questions: 1. What should I do if I forget occasionally? Make a note of the day you forget, and continue to record it according to the normal procedure, because the final look is the overall trend, the lack of a day has an impact, but also can still explain the problem. 2.What kind of temperature is normal? The normal situation is that there is both a low temperature period and a high temperature period. We call this a biphasic body temperature. And the difference between the body temperature and high temperature in 0.3 to 0.5, high temperature phase of not less than 12 days. 3.Abnormal body temperature? Basal body temperature abnormalities can be seen as low temperature abnormalities and high temperature abnormalities in two cases. Low temperature phase abnormality: one for the low temperature phase is low, mostly below 36.5 degrees, generally between 36.2-36.3, or even about 36 degrees. Second, the low-temperature phase is high, the body temperature between 36.6-36.7, or even close to 37 degrees. The third is the low temperature phase ups and downs, low temperature period body temperature is unstable, a regular wave, high temperature phase abnormal: one for the high temperature phase rise slowly, generally between ovulation 1-2 days, at the latest 3 days to reach, temperature difference should be in 0. 4 degrees or so. Secondly, the high temperature phase is slow to drop in level, and the menstrual flow drops rapidly, there can be fluctuations of 1-3 days, but fluctuations of more than 3 days are abnormal. Third, the high temperature phase is low, the temperature difference is less than 0. 3. Fourth, the high temperature phase rises and falls are slow. Fifth, the high temperature phase is short. The high-temperature phase should be maintained at 12-14 days, less than 12 days is abnormal. Sixth, the high temperature phase is unstable. Therefore, insisting on accurate measurement of basal body temperature plays an important role in the treatment of menstrual disorders in Chinese medicine.
