In the past 100 years, German scientists made hundreds of measurements on more than 20,000 people in 185 1 year, and finally the average body temperature was 37 degrees. Therefore, human beings have always regarded the body temperature of 37 degrees as the normal standard value of health. But now the standard has changed, maybe it's global warming, the temperature of 37 degrees has become history, and we can't go back to the past. COVID-19 has arrived. In order to be healthy, people habitually measure their body temperature and check their physical condition.
Most people usually measure the underarm temperature. Normal underarm temperature is 36-37 degrees. If the temperature exceeds 37.3 degrees, they will have a fever. The underarm temperature is in the low range of 37.3-38 degrees, and 38. 1-39 degrees belongs to the moderate fever range. More than 39 degrees is a high fever, and more than 4 1 degree is an ultra-high fever! When the temperature exceeds 40 degrees, it must be treated in time, otherwise it may be life-threatening!
Man is a warm-blooded animal, and his body temperature cannot be constant forever. Body temperature will be affected by many factors such as diet, exercise, age and so on. And the body temperature fluctuates constantly. Under normal physiological conditions, the body temperature is often low in the morning and evening, high at noon, slightly higher after exercise and meals, as long as there is no problem within the standard range. People's daily maximum and minimum body temperatures generally differ by 0.5- 1 degree.
But hypothermia will make you better? The answer is wrong, this is a phenomenon of temperature loss, in a cold environment. When the body temperature is lower than 36 degrees, the blood vessels begin to contract, and the body may have symptoms such as purple lips and feel goose bumps; When the body temperature drops to 35 degrees, the human body will appear hypothermia, numbness of limbs and trembling all over; When the body temperature is lower than 35 degrees, the human muscles tremble more violently, the heart beats faster, and cardiac arrest may occur; When the body temperature is below 28 degrees, the human body will undress abnormally, fall into a coma, and the pupils will be dilated. Some people will die because of muscle relaxation and smiling.
So people's normal body temperature is 36-37 degrees, so don't worry too much. Be sure to keep healthy, watch the weather forecast, pay attention to the change of clothes, replenish physical strength in time and drink plenty of water. You must wear a mask in public places and do a good job of personal protection. If you have a high fever and lose your temperature, you must go to the hospital for treatment in time.
