What does it feel like to be wet and cold?

Humidity and coldness refers to a climatic feature that the human body temperature is much lower than the ambient air temperature in wet and cold weather, and it is also a climatic feature in winter in most parts of southern China. The south is wet and cold, and the north is dry and cold. At the same temperature, wet cooling is colder than dry cooling. Many people think that winter in the south is colder than winter in the north. Some netizens joked that "dry and cold in the north is a physical attack, and you can easily defend yourself by wearing more clothes; The wet cold in the south is a magical invasion. It's no use wearing more clothes. You have to be resistant! "

The cause of wet and cold weather

The wetter the air, the greater its thermal conductivity. In winter, the greater the relative humidity of the air, the easier it is for the human body to dissipate heat, and the colder it will feel. The south is wet and cold, and the north is dry and cold. At the same temperature, wet cooling is colder than dry cooling. When the weather is dry and cold, it blows dry wind. Although cool, it has poor thermal conductivity, and it is not easy to penetrate into the body and take away heat. The south is bitterly cold and wet. Although the temperature is not as low as that in the north, it is very permeable. Wet cooling does not mean that there is a lot of water vapor in the air, but that the air is full of droplets with a diameter of only a few microns. Although this kind of droplet is invisible to human eyes, it is easy to stick to human skin and take away the heat of the body with evaporation, which makes people feel cold.

How to keep warm when the weather is wet and cold?

① The room temperature should be kept at 15-20 degrees Celsius.

When it is dry and cold, the temperature difference between day and night is large, and colds mainly appear in the morning and evening, so you should add clothes in time when the sun goes down. In wet and cold weather, besides wearing more clothes to keep warm, we should pay more attention to keeping clothes dry.
