Read The Mystery Of Body Temperature And Health in One Article

A constant body temperature is the basis for maintaining the normal physiological functions of the human body. Even small changes in body temperature can cause a series of health problems. Moreover, there are many mysteries in body temperature, and even the active disease cells in the human body have their own preferred temperature.

Body temperature | There are differences between men and women, old and young

The normal body temperature of human is 36℃~37℃ (armpit). The body temperature fluctuates slightly within 24 hours. The body temperature is the lowest at 2-6 in the morning and the highest at 1-6 in the afternoon. The fluctuation generally does not exceed 1 °C.

A constant body temperature allows us to survive in different temperature environments, but there are slight differences in body temperature between different groups of people. Children's body temperature is slightly higher, up to 36.8 ℃ ~ 37 ℃; infants and the elderly have lower body temperature. Especially premature infants, because the thermoregulation mechanism is not fully developed, the body temperature is easily affected by the environment. The average body temperature of women is about 0.3°C higher than that of men, and it also fluctuates with the menstrual cycle. The basal body temperature of normal women takes the ovulation day as the dividing point, showing a state of low before and after high, that is, "biphasic body temperature". Before ovulation, progesterone is low, and the body temperature is generally 36.2 °C; after ovulation, the body temperature rises sharply, and the increase can reach 0.3 °C ~ 0.6 °C, so that the basal body temperature rises to about 36.7 °C. A Pennsylvania State University study found that women with anemia had 0.7°C lower body temperature and 13% less heat production than women with normal hemoglobin.

Traditional Chinese medicine describes body temperature from the perspective of yang qi: yang qi is the ability of the human body to resist external evils. If yang qi is sufficient, the functional state of the human body is full, and if yang qi is deficient, the functional state is low. People with insufficient yang qi will have a lower body temperature, generally between 35.5 and 36 °C. Yang qi is closely related to nature, which is often referred to as the relationship between heaven and man. For example, in winter, we should pay attention to the hidden yang qi, otherwise, we will easily get sick in the coming year.

36℃ | Health warning line

In the early morning hours of the day, when the body temperature is the lowest, it is often also the peak period of death, and the early awakening of patients with asthma, insomnia, and depression is also likely to occur during this period. The body temperature is higher in the afternoon, and it is also the time when the physical and mental conditions are at their best. The following body temperature mysteries are especially closely related to health.

36℃~37℃: The immunity is the strongest. A normal body temperature means that the basal metabolic rate is normal, and the blood is full of fresh oxygen and nutrients, which can improve the function of white blood cells, help resist the invasion of viruses and bacteria, and enhance immunity.

Below 36°C: The body has a red flag. When the body temperature is lower than 36 ℃, the body will tremble to generate heat, and accompanied by dark circles, red nose, complexion, palms, purple lips and other symptoms. This is due to poor blood circulation caused by a drop in body temperature, white blood cells not working properly, and a weakened immune system. Asthma, pneumonia, rheumatism and other diseases will naturally come to you at this time.

Below 35°C: Most deadly to the elderly. When the body temperature drops to 35°C, it is called hypothermia. The patient feels aversion to cold, clammy skin, cold limbs, unwillingness to get up, difficulty in walking, and the elderly and malnourished people are most likely to appear. At 35°C for more than 24 hours, cardiac arrest is likely to occur.

When the body temperature drops to 32°C, the chills disappear and drowsiness occurs; when the temperature drops to 28°C, ventricular fibrillation occurs, which can eventually lead to cardiac arrest; when the temperature drops to 25°C, the patient is in a coma, the reflexes disappear, the pupil size varies, and the patient responds to light. The response is weak; at 20°C, the heart will stop beating.

To keep your body temperature normal and stay healthy, try the following tips.

1. The room temperature was maintained at 20°C. The annual average temperature of Bama in Guangxi is about 20 ℃, and it is also the hometown of longevity respected by the World Health Organization. The best room temperature for sleep is also around 20°C. Above 24°C, sleep becomes lighter, and the number of times of turning over and pushing the quilt increases. When the room temperature drops below 18°C, it is not easy for people to sleep deeply.

2. Take a hot shower. Studies have found that taking a bath in a bathtub with hot water at 35°C to 40°C can promote blood circulation, open pores, relax nerves, help clean skin, enhance metabolism, and eliminate fatigue.

3. Walk briskly often. The "large heat generator" of the human body is the muscles, and the muscles of the lower limbs are very rich. Regular brisk walking can exercise the muscles of the lower limbs, and the basal body temperature can be raised to make the body full of vitality. It is recommended to walk 10,000 steps a day, wear well-fitting shoes and well-ventilated clothing.

In addition, when the body temperature changes, people are used to touching their foreheads with their hands to see if they have a fever, but in fact, the abdomen is the best place to sense body temperature. Chinese medicine believes that the abdomen is "the palace of the internal organs and the source of yin and yang, qi and blood." If you touch the abdomen with your hand, if the abdomen is cold, it means that the blood circulation under the navel is not very good.
