When it comes to body temperature, no one is unfamiliar with it, it is the temperature of the body. Yes, but have you ever noticed that the human body temperature fluctuates throughout the day, and eating, exercising, and emotional excitement can all affect the body temperature. So which body temperature can reflect the real condition of our body? The answer is the basal body temperature.
What is basal body temperature? Usually, we call the state when the body is awake and very quiet, not affected by muscle activity, mental tension, food and environmental temperature, etc. The body temperature in the basal state is called the basal body temperature, also called the resting body temperature. Measuring basal body temperature with smart basal thermometer is more meaningful for women who are preparing for pregnancy.
1、Measuring basal body temperature to know whether ovulation is occurring
If the basal body temperature is biphasic (low before ovulation and high after ovulation), then it means that ovulation may have occurred. If the temperature is monophasic (the basal body temperature is at the same level for the whole month), it means that ovulation is probably not taking place. However, there is one condition that we need to pay special attention to, and that is "unruptured follicle luteinization syndrome". This is a disorder of ovulation in which the follicles are mature but do not rupture and the oocytes are not expelled. In case of biphasic basal body temperature, regular menstrual cycle, cervical mucus or endometrial biopsy, normal tissue secretion, ultrasound detection of follicles, mature follicles but no ovulation, etc., if other causes of infertility are ruled out, it is important to consider if you are suffering from unruptured follicular luteinization syndrome.
2. Measure the basal body temperature to understand whether the luteal function is normal
The function of the corpus luteum is to secrete progesterone, which is an important hormone that regulates menstruation and ensures normal pregnancy. If the corpus luteum does not function well, there will be problems with progesterone. A biphasic body temperature with the day of ovulation as the dividing line before low and after high shows normal luteal function. A luteal phase of less than 12 days and a temperature rise of less than 0.3 to 0.5°C is considered luteal insufficiency. However, it should be noted that this method cannot be used as the basis for diagnosing luteal insufficiency.
3、Measuring basal body temperature to know whether you are pregnant or not
If the basal body temperature rises and does not drop (generally considered high temperature period days greater than 16 days), and menstruation does not come, then it means that it is likely to be pregnant! In the first 3 months of pregnancy, if the basal body temperature decreases significantly, it may be a precursor of early miscarriage.
4、Measuring basal body temperature helps to diagnose other clinical problems
Assists in diagnosing the type of bleeding: For patients with irregular vaginal bleeding, the timing of the bleeding complaints is often difficult to determine the menstrual cycle, and the application of basal body temperature can provide a relatively true and reliable picture of the full menstrual cycle.
Suggests the possibility of pelvic tuberculosis and endometriosis: If the basal body temperature is too high at baseline, pelvic tuberculosis and endometriosis need to be considered in gynecologic endocrine patients.
Having said that, how to measure basal body temperature scientifically? Since the basal body temperature is the body temperature when the body is "undisturbed", it is important to exclude the interference of the external factors mentioned earlier, and take the body temperature by mouth for 5 minutes in the morning after waking up without getting up, talking, eating or drinking.
It should be reminded that the basal body temperature needs to be measured continuously for 3 months to be of clinical reference value. In addition, this method is not suitable for people with irregular work and rest, such as some women who have to work at night, or often insomnia, early awakening, so the basal body temperature measured is not accurate.
