Mountain climbing in summer, scorching sun and high temperature are the biggest challenges to face. How to avoid thermal fatigue?

The heat generated when climbing mountains,

In winter, it is a "timely help"

Summer is "adding fuel to the fire".

In hot summer, climbers sometimes have to compete with the sun in order to catch up with time.

However, the heat generated by your muscles during exercise, coupled with the strong concern from the sun, is actually close to "seriously exceeding the standard" in many cases! This kind of over-standard, like a car whose engine is overheated due to fatigue driving, will lead to a strike if it is not cooled in time!

However, in hot summer weather, it is easy to sweat too much and not replenish water in time, thus falling into thermal fatigue crisis caused by dehydration.

Whenever the body is dehydrated due to perspiration, the blood volume will decrease by 100ML, the body temperature will increase by 0. 1℃, and the heart rate will increase by 5 times per minute. Therefore, in order to climb the mountain comfortably, it is necessary to restore blood volume.

Drinking water is a must!

How to drink water? Buddhism may say: Is it important to drink more and drink less? Drink whatever you want! But it's really not Buddha's nature to drink water when climbing mountains in the scorching sun and unbearable heat!

Note: Drinking water when climbing a mountain is the same as drinking water every day. You should drink it in a "small amount and many times" way. Drinking too much water in one breath and doing high-intensity exercise will make your stomach feel worse.

Water, the more you drink, the more thirsty you are. What should I do?

As we said before, you can't drink water too casually when climbing mountains. Some self-righteous hardcore people don't want to drink water even if they are sweating. In the second half of exercise, it is easy to dehydrate and raise the body temperature, leading to mild or severe heatstroke.

But some people are just the opposite, because drinking too much water will make them thirsty, leading to water poisoning!

What is water poisoning? When we drink too much water, the concentration of electrolyte (salt) in the blood is too low, which will cause harm to the body. This is the so-called "hyponatremia".

Especially when climbing mountains in summer, you sweat a lot and lose more salt. Hyponatremia can cause muscle spasm, loss of consciousness and other symptoms. At this time, the situation is not only so simple as fatigue, but also very dangerous!

Therefore, we should pay attention to eating salty food or drinking some sports drinks while supplementing the lost water according to the formula recommended above.

Sweating does not evaporate? It will still lead to thermal fatigue!

The evaporation of sweat takes away a lot of heat generated during exercise and puts out the small burning stove in our body.

Here, draw the key point: "sweat evaporation"!

Sometimes, in hot summer, we are exposed to the harsh environment in the wild-hot and humid! Especially in the hot and humid south in summer.

In this case, although we sweat a lot and are diligent in hydrating, sweat accumulates on our bodies, which makes it difficult to evaporate, making hot air accumulate in our bodies, and our body temperature will continue to rise, causing thermal fatigue and eventually leading to heatstroke!

In severe heatstroke, sweating will stop, body temperature will rise faster, consciousness will be blurred gradually, and the ability to act will be lost, which will eventually endanger life.

Therefore, if you face this situation in the wild, the most correct way is to stop climbing.

Finally, it is very important to remind that if you want to climb the mountain in this hot summer environment, you should make plans in advance to avoid being ravaged by the sun during the day, choose a relatively cool time to travel, and be fully armed to do a good job of personal heatstroke prevention and cooling.
