Why do many people feel so cold?
Many netizens feel "freezing and cracking". Why is this happening?
"Science and Technology Daily" quoted experts as explaining that this is mainly due to the strong wind. The phenomenon that the body temperature is lower than the actual temperature caused by the wind is called the "wind chill effect". The wind chill effect makes people feel more "freezing." .

In life, most people have this experience: when you are standing still or walking on foot, you feel the heat and cold are just right. At this time, if you ride an electric bike, you will immediately feel the wind and the cold all over.
This is because the human body temperature is generally 36 ℃-37 ℃, in most cases it will be higher than the ambient temperature, in the absence of wind or breeze, the air molecules around the human body exchange is very weak, which is between the human body and natural air A relatively stable transition layer is formed between.
Since air is a poor conductor of heat, this transition layer plays a role in keeping warm on the surface close to the human body.
However, when the air flows quickly, the air insulation layer around the human body is continuously replaced by the new cold air and the heat is taken away.
The higher the wind speed, the faster and more heat the human body loses, and the more people feel colder.
This is why people feel colder on a windy day than when there is no wind or a breeze under the same temperature.
According to Shi Yan, a weather analyst at China Weather Network, from the perspective of today’s highest temperature, the areas in central and eastern Inner Mongolia, Heilongjiang, Jilin, and Xinjiang along the Tianshan Mountains are the most western and northernmost regions in my country, and are the earliest affected areas by cold air. Because of the above factors, the temperature in the above-mentioned areas is less than -18°C in the whole weather.
