For many people,

Participants in cross-country marathons are mostly people with excellent physical fitness.

But why is there such a huge loss?

Investigate the main cause of the accident.

Is the temperature loss.

What is temperature loss? How dangerous is it?

The optimum temperature of marathon is about 10- 15, but it is also very important for the body to adapt to the external environment temperature (cold and hot environment), and body temperature regulation is one of the keys. When the heat production rate is lower than the heat dissipation rate, the heat in the body is less and less, which is not enough to keep the body temperature, and the phenomenon of "temperature loss" will occur.

The main reasons for temperature loss in outdoor sports are:

The environmental temperature is too low and there are too few clothes, which makes the human body lose too much heat through body surface conduction;

The body lacks energy, especially in the late stage of exercise, because of the consumption of energy substances in the body, there is not enough energy to generate heat and maintain body temperature.

When the temperature is too low, the biological enzymes in the body will fail, making it difficult to carry out the chemical reaction of the human body, thus inhibiting the function of the human body and even leading to death in serious cases.

What are the symptoms of hypothermia?

Mild temperature loss

When the patient's body temperature drops to 33-35℃, there will be severe chills, cold limbs, pale face, serious fatigue, unclear language, uncontrolled muscles, slow movement, memory loss, emotional changes or irrational, slow pulse, hallucinations and so on.

Severe temperature loss

The patient's temperature dropped below 32, and he lost consciousness and entered a state similar to hibernation. Specific manifestations are no longer muscle spasm, slow pulse and respiratory rate, greatly reduced blood circulation on the body surface, loss of consciousness and so on.

Why is there a phenomenon of temperature loss and death in summer?

The human body itself is a pyrogen, which transfers heat with the outside world anytime and anywhere, among which temperature, humidity and wind are the most common factors leading to temperature loss.

Even in summer, there will be a temperature difference in the morning and evening. Due to the increase of sweat and humidity brought by marathon and the increase of wind, it is very easy to dissipate heat quickly, causing temperature loss, not to mention the bad extreme weather.

There is a temperature loss, how to rescue it?

Step 1: Safe transfer

In many cases of hypothermia, the victims are exposed to harsh environment, which leads to hypothermia. At this time, outdoor activities should be stopped immediately, and the patient should be moved to a sheltered place, hiding behind rocks and other obstacles. Set up tents for rescue when necessary.

Step 2: Cold noodles are isolated

After the patient is safely transferred to the shelter, the cold ground will continue to eat away valuable heat. At this point, the second step of the rescue team is to quickly isolate the patient from the ground with a sleeping pad to prevent the patient's core body temperature from continuing to lose. Because heat will be transferred from high-temperature objects to low-temperature objects, the function of the sleeping mat is to block the ground and slow down the heat transfer process.

Step 3: drying.

When the patient has symptoms of hypothermia, he may have been walking in the snow for a long time, and his inner clothes are soaked; Rain and snow outside will also wet clothes. Rescuers should help the patient change clothes as soon as possible, dry the patient's body with fabric, keep the patient dry, and wrap the patient's whole body with sleeping bags or thick clothes.

Step 4: Heat the core area.

When the patient loses temperature seriously, he will lose consciousness and his muscles will no longer tremble, which also shows that the patient's body has lost the ability to provide heat for the body. At this time, it is useless to put it in a thick warm object, and only the core parts, such as the patient's neck, armpits and groin, can be heated externally. It's wrong to warm your limbs.

Attention! Don't try to heat limbs or drink hot water for people with severe hypothermia. Hypotension and further temperature drop caused by massive hypothermic blood circulation will increase the risk of resuscitation failure.

How to prevent temperature loss?

Pay attention to the choice of underwear. Most people who travel outdoors pay attention to rain and snow protection, only to keep warm, and ignore the risk of temperature loss caused by a lot of sweating. Choose underwear that dries quickly and perspires, and avoid cotton underwear. Cotton fabric is very absorbent and difficult to export, resulting in temperature loss.

Pay attention to the increase or decrease of clothes. Before hiking in cold areas, put warm clothes in your carry-on bag and put on a thin quick-drying T-shirt or a well-ventilated coat when you leave. Take out warm clothes at every rest point to avoid catching cold and losing temperature.

Keep warm. If you travel in cold weather, you should take corresponding windproof measures and not be exposed to the cold wind. Warm hats, gloves, scarves, windbreakers, thick socks, wind masks, etc. They are all necessary items for travel in windy weather and cold weather.

Replenish physical fitness in time. Don't let your physical strength overdraw, prevent dehydration and avoid excessive sweating and fatigue. Prepare food and hot drinks to replenish body heat at any time.

How to help people who have lost their temperature? Never give alcohol to patients with hypothermia.

If you find someone looking cold, shivering violently, uncoordinated or even unconscious outdoors, it is likely that he is facing the threat of losing his body temperature and needs your help urgently.

In recent years, more and more people are keen on outdoor sports. Everyone should master the relevant rescue knowledge well.

Remember not to give the patient alcohol, nor to wipe or massage the patient's limbs, so as not to let a lot of cold blood flow back from the epidermis to the heart, causing arrhythmia.
