Now, due to novel coronavirus, the frequency of measuring body temperature has greatly increased. Careful people will find that their body temperature is generally less than 37℃, so they question whether the normal body temperature is 37℃. Are they abnormal or has the body temperature generally dropped?

The statement that the normal body temperature is 37℃ was made by a German physician after collecting axillary temperature data of 25,000 patients in 185 1 year. Until now, it is still the standard for us to judge whether we have a fever.

In fact, scientists have long been aware of the changes in human body temperature. I looked up some information and said? The adult's body temperature has been dropping continuously, dropping by 0.4℃ in less than 200 years, from 37℃ to 36.6℃? Even though people's body temperature is different at different ages, at different times and in different parts, the average body temperature has indeed dropped. Some people around me say that hypothermia is far from the temperature of fever and illness. Is that really the case?

Some time ago, I read an article about bats, the source of novel coronavirus. I sighed, too. Yes, there are hundreds of viruses in bats, but they are not dead because their immune system protects them, and their body temperature has been maintained at around 40℃. How can scientists let go of this detail and study the relationship between immunity and human body temperature? It is estimated that when the body temperature drops by 65438 0℃, the immunity will decrease by 30%, which explains why bats will not die.

Some professionals have given their own explanations for the causes of hypothermia.

1, lack of exercise. Nowadays, people with advanced technology are doing less and less, so their metabolism will also decrease and their body temperature will also decrease.

2. Stress. In today's fierce competition, people's pressure is increasing, which will lead to excessive cortisol secretion, muscle decomposition, fat storage, lower basal metabolic rate and lower body temperature.

3. Use the air conditioner for a long time. When it is hot, the human body will sweat, but air conditioning will make the skin feel cool and won't sweat. Over time, the brain's thermoregulatory center will be dull and the body temperature will drop.

There may still be many reasons that have not been discovered, but we should realize that our immunity has decreased, exercise more, relax and blow less air conditioners.
