Winter swimming won't cause hypothermia, so why does marathon cause extensive hypothermia death?

The Gansu Marathon accident has made many people have a deep understanding of the word temperature loss. The Gansu Marathon was affected by extreme weather, which caused a large number of contestants' body temperature to drop. In fact, many people don't understand why there is temperature loss in summer. Winter swimming won't cause the body temperature to drop?

Why doesn't winter swimming lead to a drop in body temperature? In fact, it does not mean that winter swimming will not produce wet temperature, but that winter swimming strictly controls the time. If the time is not well controlled, it will also lead to the loss of human body temperature. Generally speaking, the winter swimming time should not be too long, and it is best to control it in a few minutes to ten minutes. Winter swimming can't go on like a hot spring, because the human body can't stand the low temperature. In addition, winter swimming is not suitable for everyone, so don't try it blindly.

Why do marathons cause widespread hypothermia and death? Why the marathon will cause a large area of hypothermia death is caused by sudden extreme weather. The sudden arrival of extreme weather has led to a serious deviation between the temperature of the ground and the temperature of the mountain. Besides, this competition is very long. Before the sudden extreme weather came, the contestants had been running for nearly ten hours.

During the whole competition, there was no other food supply, and the players consumed a lot of physical strength. When physical fitness is consumed in large quantities, they encounter sudden extreme weather, which makes the heat generated by digested physical fitness insufficient, thus causing a large number of players' body temperature to drop.

The contestants were soaked in rain. At this time, the heat of the players spreads faster in the water than in the air, and the rain pouring on them will accelerate the heat dissipation. Without warm-keeping measures, the body's heat is constantly taken away by the air. At this time, it is easy to lead to death due to hypothermia.

When the body can't keep up with the heat production, the heat dissipation is greater than the heat production, and the heat dissipation is faster and faster, and the core temperature drops rapidly, the temperature loss will be particularly fast, and then it is inseparable from such an extremely low temperature environment. Most railway tracks are no man's land, so it is impossible to provide materials and medical assistance in time. When it reaches the level of severe hypothermia, there will be heart and lung failure, and eventually the heart will stop beating and people will die.

Many people misunderstand the word temperature loss, thinking that temperature loss will only occur in winter. Actually, it is not. The temperature loss has nothing to do with the season. Even in summer, the temperature will drop. Temperature loss is like a silent death, which will inadvertently take away people's lives.

In fact, outdoor sports are risky, so outdoor sports enthusiasts had better take safety measures and carry a piece of clothing with them under any circumstances to keep warm in case of sudden weather and avoid body temperature loss.
