What is basal body temperature
Basal body temperature is measured when a person is just awake in the morning, lying in bed in a calm state with no activity and no food Axillary temperature. Basal body temperature is the lowest point of a person’s physiological temperature in a day. Basal body temperature can help to judge gynecological and obstetric diseases, and help diagnose diseases of ovulation dysfunction. A person’s body temperature during the day is the lowest in the early morning when there is no activity. During the day, after eating, after activities, and when emotional, the body temperature will rise, but usually no matter how it fluctuates, it is within the normal range. If the body temperature exceeds the normal range for a long time, it is considered to have abnormal body temperature. If the axillary temperature exceeds 37 °C, it is considered to have fever. When the axillary temperature is lower than 35 °C, it is considered to have hypothermia.
The relationship between basal body temperature and ovulation
For the relationship between body temperature and ovulation, more strictly speaking, it should be the relationship between basal body temperature and ovulation. In clinical practice, basal body temperature is often used to monitor whether ovulation occurs. Before ovulation, basal body temperature is relatively low, and on the day of ovulation, basal body temperature will drop by 0.3-0.5 °C compared with the previous day, that is, ovulation during the entire menstrual period. The temperature of the day was the lowest. After ovulation, due to the formation of the corpus luteum in the body to stimulate the body temperature center, the basal body temperature rises, so the body temperature tends to rise on the second day of ovulation, usually around 37°C, and this high temperature state has continued for 12 days or more. If the high temperature lasts for more than 15 days, the possibility of pregnancy is very high, and most menstruation occurs when the high temperature lasts for 12-14 days.
36.4°C = Breeding – starts on the second day of menstruation and lasts about two weeks.
36.7°C = Ovulation – 1-2 days after ovulation.
37°C = Pregnancy – After ovulation, the basal body temperature remains high at 37°C for about two weeks. 37°C is the most suitable for fetal development. Therefore, most of the reasons for miscarriage are that the mother’s basal body temperature cannot be maintained at 37°C, high or low, which will lead to miscarriage.
How to measure basal body temperature
1. Buy a basal thermometer. The basal thermometer is different from general thermometers in that its scale is relatively dense, and generally takes 36.7 degrees Celsius (scale 24) as the boundary between high and low temperatures. (36 degrees–scale 10; 38 degrees–scale 50).
2. Put the basal thermometer on the side of the pillow before going to bed, where you can get it easily. When you wake up the next day, before you get up to move, put it under your tongue to measure it for three minutes, and record the basal body temperature. on the table.
3. If it is difficult to measure the body temperature in the morning, you can do it at a certain time every day, and remember not to exercise vigorously or drink hot or cold food half an hour beforehand.
4. Menstrual cramps and the day of the same room must be marked with a mark. In case of a fever, drinking too much, going to bed late and getting up late, etc., which will affect the body temperature, special notes should also be noted. Precautions for measuring basal body temperature In order to improve the accuracy of measuring basal body temperature, the mercury column on the thermometer should be thrown below 35 degrees before going to bed every night, and it should be placed on the bedside table or by the pillow so that it can be easily taken when using it. Minimize activity. If you get up and take a thermometer, it will increase the basal body temperature and make the temperature value of the day meaningless.
