What is the normal body temperature?

Our normal body temperature is usually 36.5 degrees, and we feel that our body temperature is constant. In fact, this is wrong. Our body temperature is different in different weather conditions, and there are some differences in the morning and evening of each day. The temperature is also different between men and women. So what is the normal body temperature of the human body? The temperature of different parts is also different.

What is the normal body temperature of the human body? Do you all know our normal body temperature? Do you also know that the temperature of different parts of our body is different? Some temperatures are higher, some are lower, but under normal circumstances, the temperature is within the normal range.

The normal oral temperature is 36.5～37.2℃, and the armpit temperature is lower than the oral temperature. 0.3～0.6℃, rectal temperature (also called anal temperature) is higher than oral temperature. 0.3 ～0.5 ℃. In the biological rhythm of a day, body temperature is lowest between 2 and 5 in the morning and highest between 5 and 7 in the afternoon, but the difference within a day should be less than 1°C. In addition, the body temperatures of men and women are also different. Women's body temperatures are generally about 0.3 ℃ higher than men's. Women's body temperature is also related to menstruation, which I will not go into details here. Therefore, human body temperature has a relatively stable range, but it is not constant.

Body temperature refers to the temperature inside the body. The normal axillary temperature is 36-37 degrees, the oral temperature is 36.2-37.2 degrees, and the rectal temperature is 0.3-0.5 degrees higher than the oral temperature.

The temperature of a normal human body is relatively constant, with slight fluctuations within 24 hours, generally not exceeding 1 degree. Under physiological conditions, body temperature is slightly lower in the morning and slightly higher in the afternoon. The body temperature is slightly higher during exercise, after eating, before menstruation or during pregnancy for women, while the body temperature is lower in the elderly. A body temperature higher than normal is called fever, 37.5-38 degrees is low fever, 38-39 degrees is moderate fever, 39-40 degrees is high fever, and above 40 degrees is very high fever. Body temperature below normal is called hypothermia. A relatively constant body temperature is one of the important conditions for maintaining normal life activities. If the body temperature is higher than 41 degrees or too low, it will seriously affect the functional activities of various systems (especially the nervous system) and even endanger life.

The average normal human body temperature is between 36 and 37 degrees Celsius (axillary). Exceeding this range is fever, below 38 degrees Celsius is low fever, and above 39 degrees Celsius is high fever. The above is dangerous. When measuring body temperature, you should first shake the mercury column of the thermometer to below 35℃, and then wipe and disinfect it with a cotton swab dipped in alcohol. Nowadays, most people test the temperature by holding the thermometer under the armpit. For young or unconscious children, the rectal temperature can be measured. When measuring the temperature under the armpit, wipe off the sweat in the armpit first, then place the end of the thermometer with the mercury column under the armpit and clamp it, then take it out after 5 minutes. When measuring rectal temperature, first apply some oil on the round tip of the rectal thermometer for lubrication, then slowly insert it into the anus to a depth of about 2 cm, and remove it after 3 minutes. When measuring rectal temperature, hold the thermometer with your hand to prevent the child from breaking the thermometer and injuring the anus. When looking at a thermometer, you should hold it horizontally and rotate it slowly, taking the horizontal line to observe the temperature scale indicated by the mercury column. After use, the thermometer should be disinfected with 75% alcohol.

The normal body temperature is generally higher in the morning than in the afternoon. The morning temperature of a one-month-old baby is 0.25℃ higher than in the afternoon, the morning temperature of a six-month-old baby is 0.5℃ higher than in the afternoon, and the temperature of a baby over one year old is 1℃ higher. , Neurological aspect: The "sensors" in women's skin are more sensitive than those in men's, and women have the mission of reproducing offspring. During pregnancy, the fetus in the uterus needs a constant temperature environment, and the uterus is inside the torso, so the woman's torso needs to be more carefully protected. To achieve this goal, the "sensors" in women's skin must be more sensitive. 2. Hormones: Women's ovaries form corpus luteum, and the secretion of progesterone by the corpus luteum will increase body temperature. The body temperature regulation center is extremely sensitive to the effects of progesterone (also known as progesterone). A certain amount of progesterone (12,8nmol/L) can cause body temperature to rise. 3. Women have higher body fat than men, which should also be a reason. Children are high, and infants are experts' answer: The body temperature does not exceed 37°C on the oral table, and 37.6°C on the rectal table is the normal body temperature. An oral thermometer is a thermometer that measures body temperature in the mouth. What is the normal body temperature of a young child (under the armpit)? After a child is born, the normal body temperature is slightly higher than that of an adult and is prone to fluctuations. This is because children have an active metabolism and their temperature regulation center is not yet fully developed. The normal body temperature of children is generally around 37 to 37.2 degrees Celsius. In a few children, the highest body temperature in a day can reach 37.4 degrees Celsius. In addition, children's body temperature can fluctuate greatly within a day. The temperature of young children can differ by 0.5 to 1 degree Celsius within a day, while that of older children can vary by more than 1 degree Celsius. The body temperature is higher after meals, after exercise, after bathing, after crying, after sweating a lot, and in hot weather and in the afternoon. In contrast, body temperature is lower in the morning and during sleep. Because normal body temperature varies from person to person, not all children's normal body temperature can reach 37.2 degrees Celsius, or their body temperature fluctuates by 0.5 to 1 degree Celsius in the morning and afternoon every day.

What is the normal body temperature of the human body? We should pay attention to abnormal changes in our body temperature. Especially if some children have a low fever and their body temperature is maintained below 37 degrees, and it remains at this temperature for a long time, we should pay attention to it. We should measure the child's body temperature regularly to avoid any unexpected phenomena.
