What causes low basal body temperature

Mechanism of basal body temperature change The thermoregulatory center is extremely sensitive to the action of progesterone (also known as progesterone), and a certain amount of progesterone (12,8 nmol L) can cause an increase in body temperature. The day after ovulation, due to the formation of the corpus luteum in the ovaries, the secretion of progesterone by the corpus luteum will cause the body temperature to rise by about degrees Celsius, and the body temperature will show a two-phase change of high and low. The high temperature period lasts about 12-16 days (14 days on average).

If there is no pregnancy, the corpus luteum atrophy stops secreting progesterone, the body temperature drops, returns to the baseline, and menstruation begins. If you are pregnant, because the corpus luteum is supported by the hormone secretion of the embryo, it continues to secrete progesterone, and the body temperature continues to be high. If the ovaries are not functioning well, there is no ovulation and no corpus luteum, so the body temperature will continue to be cold.

The length of the female menstrual cycle begins on the first day of the menstrual redness, and the length of the cycle varies from person to person, ranging from about 21-35 days, with an average of about 28 days, which is separated by the day of ovulation, the follicular phase before ovulation, and the luteal phase after ovulation. The length of the follicular phase is not necessarily, but the normal luteal phase is fixed at about 14 days plus or two days. How to measure It is recommended to use a special basal thermometer, which is different from the general thermometer in that it has a dense scale, and generally takes Celsius (scale 24) as the boundary between high and low temperatures.

36 degrees - scale 10; 38 degrees - scale 50).Put the basal thermometer in a place within easy reach of the pillow before going to bed, and when you wake up the next day, when you have not yet gotten up and move, put it under the tongue for five minutes and record it on the basal thermometer. If you have difficulty measuring your body temperature in the morning, you can do so at a fixed time every day, and remember not to exercise vigorously or drink hot or cold food half an hour before the event.

Although the method of measuring basal body temperature is simple, it is demanding and requires long-term adherence. Generally, it takes more than 3 consecutive menstrual cycles to explain the problem. During the menstrual period, if you have a cold, fever, diarrhea, insomnia, drinking, using electric blankets, etc., it is often easy to affect the basal body temperature.

The human body temperature is 36-37. The thermoregulatory center is in the human brain. causes of hypothermia; Serious disease, poor regulation of the center, lack of body heat. I think your hypothermia is an individual difference.

There are a lot of reasons, and it's not necessarily a disease, but some of them are because of the mechanism itself.

There are differences in body temperature in all parts of the human body, in the morning and evening, and between men and women. There is a relatively stable range of normal body temperature, but it is not constant. In a normal person, the oral temperature (also known as oral temperature) is lower than the axillary temperature and the rectal temperature (also known as anal temperature) is higher than the oral temperature.

During the day, the temperature is lowest at 2 5 a.m. and highest at 5 7 p.m., but the temperature difference should be less than 1 in a day. In addition, women's body temperature is generally higher than that of men. A woman's body temperature also changes slightly during menstruation.

The average normal body temperature in the human body is between 36 and 37 (armpits).

Generally speaking, the human body has its own thermoregulation system, which we call basal body temperature, and some people have low basal body temperature, so what is the reason for low basal body temperature?

Changes in body temperature are also related to age, with young people having a high body temperature and older people having a low body temperature. With age, the body temperature tends to decrease gradually, with an average decrease for each additional age group (10 years).

Low basal body temperature is common in people with weak constitution or cold constitution, and people with cold constitution are susceptible to cold and damp damage due to poor blood circulation, resulting in lower basal body temperature. Generally, if there are no special symptoms of discomfort, do not worry too much, if accompanied by other physical discomfort, you can see Chinese medicine, the doctor will take the pulse, if the diagnosis is cold constitution or kidney yang deficiency, you can take Chinese medicine**.
