When it is windy in winter, people always feel particularly cold. Why?

The weather is cold and the temperature is lower than the body temperature. At this time, the body is heating the small air layer for you in obscurity, so the temperature of the small air layer is slightly higher than the temperature and slightly lower than the body temperature. If there is a strong wind at this time, the small air layer that was easily heated by your body will be blown away with a loud cry and replaced by a "new" small air layer with lower temperature, and you will naturally feel cold.

Also, there is humidity. Humidity also affects the somatosensory temperature. For example, when it is cold, the greater the humidity, the colder it is; When it is hot, the higher the humidity, the hotter it is. The most typical examples are Beijing and Shanghai: in summer with the same temperature, Shanghai feels more sultry; In winter with the same temperature, Shanghai feels colder and more biting. This is the force of humidity on the somatosensory temperature.
