The relationship between temperature and body health

(Summary description)  Why is it that no matter how the ambient temperature changes, the human body temperature can always remain at a constant temperature of about 37℃? Research shows that not only a constant body temperature is very important for health, but there are many other temperatures in life that are related to health, such as indoor and outdoor temperature, food and drinking temperature, face and bath temperature.

  Why is it that no matter how the ambient temperature changes, the human body temperature can always remain at a constant temperature of about 37℃? Research shows that not only a constant body temperature is very important for health, but there are many other temperatures in life that are related to health, such as indoor and outdoor temperature, food and drinking temperature, face and bath temperature.

  "Everyone has a different temperature, but it's generally around 37 degrees Celsius. "Humans have survived selection in nature by relying on an advanced thermoregulation system to 'keep things constant'." Zhang yimin, associate professor at the school of sports and human sciences at Beijing sports university, told reporters.

  About 37℃ : normal temperature. The data, which dates back to 1868, is an average of the armpit temperatures of 2,500 adults. But McVeigh, of the medical school of Maryland, later measured 148 people's mouths and came up with an average of 36.8 degrees. The results showed that the range of temperature variation between individuals was within 2.7 degrees, which was normal. There are subtle differences in body temperature. According to a new study from Yale university, people with a higher body temperature are generally nicer and more likely to give away their possessions. People with lower body temperatures do the opposite.

  "A normal person's body temperature fluctuates slightly within 24 hours of a day, varying by 0.6 degrees." "Body temperature is lowest at 6 a.m. and highest at 4 p.m. Women have slightly higher body temperatures before menstruation or during pregnancy, while older people have lower body temperatures, zhang said.

  In addition, "muscle activity generates heat, which causes body temperature to rise." Mental tension and emotional excitement can also raise body temperature. When people are nervous, their body temperature will rise by about 2℃ at most. However, after anesthesia, the body temperature will drop, so keep warm.

  In addition to body temperature, people have "skin temperature", which is the temperature of the skin surface. When the ambient temperature is 23℃, the frontal skin temperature is generally 33-34℃, the hand is 30℃ and the foot is 27℃. Even human internal organs have their own temperature: liver temperature can reach up to 38℃; The brain produces more heat and the temperature is close to 38℃. The kidneys, pancreas and duodenum are slightly cooler.

  Above 37.5℃ : fever. Clinically, fever occurs when the body temperature is higher than normal; low fever occurs when the temperature is 37.5-38℃, moderate fever occurs when the temperature is 38-39℃, high fever occurs when the temperature is 39℃-40℃, and ultra-high fever occurs when the temperature is above 40℃. When the temperature is higher than 41℃ or lower than 25℃, it will seriously affect the functions and activities of various systems, especially the nervous system, and even endanger life. It is a myth that many people treat a fever as if it were a disease." The fever itself is not a disease, but a symptom, and it is one of the body's mechanisms for fighting infection, said professor zhang, the ministry's chief health education expert. In some ways, fever is even "good", shortening the duration of illness, enhancing the effectiveness of antibiotics, making infections less infectious and so on.
