How long will people freeze to death?

One died of heart failure in about 5-50 minutes. One died of upper respiratory system and froze to death and suffocated in about 5 minutes. In fact, it is not the ambient temperature, but the heat loss of the body.

Under what circumstances will people lose their body temperature:

Exposed to cold environment for a long time, the human body will use the energy stored in the body when regulating body temperature, but the heat loss is greater than the heat supply, resulting in hypothermia or abnormal body temperature. Hypothermia will affect the brain's thinking, resulting in failure to take timely protective measures. Because people may not realize that temperature loss is happening and fail to take relevant protective measures in time, temperature loss is even more dangerous.

Temperature loss usually occurs in extremely cold weather, but it may also occur in cool weather of 4-5℃ if it is caught in the rain or soaked in cold water in a humid environment.

In the process of running, when encountering such extreme weather and strong wind, the temperature on the skin surface will decrease. In other words, when you are running, if you sweat, you will feel cool when you encounter a little wind. This is because your body surface temperature is dropping, and you will feel cool.

Therefore, when you run, you should try to choose clothes that are conducive to perspiration when the air conditions are relatively stable, so as to prevent sweat from accumulating on your skin surface and reduce the body surface temperature.
