There are many reasons for the temperature drop in outdoor sports. Do you know the main reason?

There are two main reasons for outdoor temperature loss. One is that strenuous exercise can't keep up with the speed of heat dissipation. The other is that because of the cold weather, people's body surface temperature drops rapidly, but the speed of heat production is relatively small, so there will be temperature loss.

In Gansu Baiyin Marathon, 2 1 person died of temperature loss due to bad weather, which made people feel particularly uncomfortable and sorry, but at the same time, many people were curious about the temperature loss.

First of all, strenuous exercise reduces heat production.

People who exercise outdoors consume a lot of energy because of strenuous exercise, so their organs can't produce the heat needed by the human body at once.

Marathon runners, because they are long-distance runners, have consumed a lot of energy, so it is difficult to restore people's skills.

Therefore, in the face of bad weather, due to the inability of human body function to recover, the heat generated by organs is not enough to maintain people's normal life, and there is a loss of temperature.

Second, the weather is cold and the body surface temperature is low.

The second reason why outdoor athletes lose their body temperature is the weather. Because they exercise harder, they may secrete a lot of sweat.

However, because the outside temperature is very low, the temperature of the human body surface will be even lower, and athletes will feel particularly cold at this time.

And their bodies can't produce the heat needed to maintain their body temperature. At this time, people may lose their body temperature and eventually die because of low temperature.

Gansu Silver Marathon is a pity, because among the people who passed away, there were world champions, pillars of the family and young girls. Moreover, most of the dead people run in front, they consume more physical energy and lose their body temperature faster, so their situation is more dangerous and they are more likely to die.
