What disease is the body unable to adapt to hot and cold weather?

The cold and hot feeling of human body belongs to tactile problem. Many people are used to using temperature as the only criterion to infer the human body's feeling of hot and cold (perceived temperature). In fact, the temperature perceived by the human body is sometimes far from the actual temperature. For example, people often say that "the hot weather is in the dog days", but according to the meteorological data, the highest temperature in most areas does not appear in the dog days, but appears around the dog days. People think the dog days are the hottest because the "hot" at this time is added with "wet" and sultry. People also have this experience. Under the rotating electric fan, they often feel that the wind from the electric fan is very cold, but when you put the thermometer in front of the electric fan and blow it, you will find that the temperature of the thermometer has not dropped. People feel cool because the wind has changed the air humidity. I feel cool just after swimming in summer. If it is windy, I will even tremble with cold. All these show that the influence of atmospheric environment on human body is all-round. In addition to temperature, humidity and wind are the main factors that determine the human body's cold and hot feeling, and these three factors can not be ignored.
