The normal body temperature of a person is generally 37 degrees Celsius. If it drops to 35 degrees Celsius, the symptoms of hypothermia begin to appear. At first, people can stay awake and raise their body temperature by chills. However, when the body temperature drops to 33 degrees, people may lose some of their memories. When the temperature is 28 degrees, most people will lose consciousness and choke on water. When the body temperature is lower than 2 1 degree, the blood vessels in the limbs contract one after another, blood returns, blood pressure rises sharply, and heart disease may occur, so death is not far away.

2, joint rheumatism

I don't wear enough clothes in winter, and my legs hurt every time I am blown by the cold wind. At night, I have a terrible headache and can't sleep. There are generally two reasons for this situation: one may be that the legs and feet were attacked by pathogenic wind, cold and dampness before, and with the growth of age, the body's immunity gradually declined, which is caused by cold wind. In addition, it may also be caused by insufficient kidney yang in the body. The body with yang deficiency will have cold limbs and be afraid of cold.

3, facial paralysis

If you wear thin clothes in winter and blow cold air outdoors for a long time, the cold stimulation on your face will cause local nutritional neurovascular spasm, leading to ischemia and edema of this nerve tissue and facial paralysis.
