How can we avoid outdoor hypothermia? What precautions are in place?

We must pay attention to keeping warm, and we must change wet clothes in time to rest more outdoors, only in this way can hypothermia be avoided.

Don't go out when it's cold, so when you want to go out, you should bring preventive clothes and food, enough to ensure that your body temperature is not cold, bring a pot of hot water if you can, and don't go out if the weather is too cold.

When exercising outdoors, you must observe the weather, be prepared, and evacuate immediately to ensure your safety in case of special circumstances.

There are two main reasons for outdoor hypothermia, one is that the speed of heat generated by organs caused by strenuous exercise cannot keep up with the speed of heat dissipation, and one reason is that because the weather is relatively cold, the body surface temperature of people drops rapidly, but the speed of heat production is relatively small, so hypothermia will occur.

In the Gansu ** marathon, 21 people died of hypothermia because of the severe weather, which is particularly uncomfortable and regrettable, but at the same time, many people also have a certain curiosity about hypothermia. <>

First, the heat production of strenuous exercise is reduced

People who exercise outdoors because of strenuous exercise, the energy consumed by the human body is particularly large, so their organs cannot immediately produce the calories required by the human body.

Marathon runners, because they are long-distance runners, have already consumed a lot of energy, so it is more difficult to recover their human skills.

Therefore, when they face severe weather, because the human body cannot recover, and the heat generated by the organs is not enough to maintain the normal life of people, they have hypothermia. <>

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

The second cause of hypothermia in outdoor exercisers is due to the weather, because their exercise is more strenuous and they may secrete a lot of sweat.

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

And their body is not able to produce the heat needed by the body to maintain body temperature, at this time people may have hypothermia and eventually die because the temperature is too low. <>

The Gansu ** marathon incident makes people have some regrets, because among the people who passed away, there is this world champion, the pillar of the family, and a young girl. And most of the people who die are running ahead, they consume more energy, and their body temperature is lost faster, so their situation is more dangerous and more likely to die.

The external environment has a great influence on body temperature. We can maintain a body temperature of 37 degrees Celsius at room temperature, but in extreme weather during outdoor sports, the temperature drops to an unacceptable range for the human body, which will cause the body to lose temperature.

1.The temperature of the outdoor environment is too low and the human body wears too little, which will make our body lose heat continuously. 2.

Long-distance running is a very physically demanding exercise, especially in the second half of the exercise, we will have hypothermia due to excessive energy consumption in the body and lack of timely replenishment of energy. However, when we find that our body is at room temperature, we should immediately stop exercising, seek help from medical staff and replenish energy in time, although exercise is beneficial to our physical health, but we must follow the scientific way of exercise.

inadequate food intake; Moisture, moisture takes away heat faster; Go to low-temperature environments, such as high-altitude peaks; dehydration, lack of attention to drinking water or lack of water; fatigue, prostration, such as high-intensity hiking; Inappropriate clothing and equipment, such as cotton underwear, non-breathable, waterproof jackets, sleeping bags that do not meet the temperature scale, etc.

Hypothermia is caused by the relatively low temperature and environment around the body, which leads to severe dehydration of the body, and finally a wet temperature. When you are outdoors, you must pay attention to wearing more clothes and never catch a cold, and in winter, do not stay outdoors for a long time.

It is because the temperature in this place is relatively low, the temperature drop is particularly obvious, the food is not replenished in time, and the clothes worn are relatively small, so such a situation will occur; It is necessary to observe the weather forecast in time, wear more clothes and replenish supplies.

If the outside temperature is too low, it will cause the body to lose heat quickly, which will cause this situation. Be sure to keep warm, bring some heating equipment, and also bring some food.

Hypothermia, also known as hypothermia, is a condition that occurs when the body's core temperature drops below 35. Hypothermia is not easy to occur inexplicably, and there are two main causes: one is exposure to very low temperatures; second, the body's self-produced and self-sold calorific value is lower than the temperature loss rate; Naturally, there are also these kinds of cumulative phenomena.

Ordinary people suffer from hypothermia, and it is possible to reduce or eliminate it by taking immediate measures. Exposure to very low temperatures may cause hypothermia, but there is one condition that is particularly important that hypothermia is likely not to cause concern at first, and the symptoms are gradually developing and aggravating, and many people miss the window of time to take preventive measures because they do not detect the risk of hypothermia early or because the brain is slow to respond due to hypothermia, resulting in hypothermia leading to more serious illnesses and thus life-threatening conditions.

Hypothermia occurs gradually, from mild hypothermia to mild to moderate hypothermia to moderate to severe hypothermia, which can be roughly divided into three stages, and of course can also be divided into four more accurate stages. In slight hypothermia, the body temperature drops to 32 -35. At this time, there will be numbness, trembling, exhaustion, difficulty breathing, and "goosebumps" in the limbs, which will cause slowness of movement and visual impairment; At this time, if you do not judge in time and take mitigation measures, you will enter the stage of mild to moderate hypothermia.

In mild to moderate hypothermia, the human body temperature will drop to 28 -32, at this time, people's actions will be more difficult, thinking and sense of orientation will begin to be disordered, and the tone of the face, lips, ears, hands, feet and fingers is likely to become darker, and even due to the confusion of the temperature regulation mechanism, the illusion of "warming" of the human body will occur. If there is no effective improvement, it will enter a period of moderate to severe hypothermia.

At this time, the body temperature will drop to less than 28, the ability to express language will gradually be lost, the ability to coordinate the body will be basically lost, the thinking will be dull, the breathing pulse will slow down, and the skin will gradually turn blue, thus entering the situation of syncope. First of all, it is necessary to judge and take effective measures when a minor illness occurs. If an outdoor worker has any of the following symptoms: shivering, constant chills, slurred speech, listlessness, or difficulty breathing.

It is necessary to measure the temperature in time to determine whether the temperature is lower than 35, and send it to the doctor quickly if possible. Hypothermia symptoms and rescue methodsIf the conditions are limited, if you can't see a doctor immediately, you must wait for rescue, take off wet and cold clothes as soon as possible, and use dry clothes or other shelters to maintain the temperature of the core areas such as the opening game, chest, and groin area. Start a fire immediately to heat or go into a warm place.

If necessary, drink lukewarm water immediately, but don't drink alcohol!

It will cause your body to cool down quickly, and it will also cause you to be unable to adapt to the environment, which will lead to your own these. Be sure to keep warm when surviving outdoors, so as to prevent such things from happening.

In this case, the body's functions may become abnormal. Take precautions to keep warm, such as lighting a fire in the wild.

Difficulty speaking, sluggish thinking. Exposed ** turned blue, muscle coordination was almost completely lost, unable to walk, and even comatose. Pulse and breathing are markedly slowed, and rapid heart rate or atrial fibrillation may occur, eventually leading to cardiopulmonary failure.

Outdoor activities in cold weather, keep your body dry, and if you get wet, change into dry clothes quickly; Pay attention to the addition and removal of clothing. Many people like to wear thick clothes when hiking, for fear that they will catch a cold on the road, but they don't go far, and their bodies are wet with sweat, and it is easy to lose temperature.

First of all, find a safe place for yourself, avoid direct cold winds, change dry and warm clothes, and eat these foods that are high in sugar.

If you are aware of hypothermia, you should first make sure that you have a warm environment, such as going into a warm place, or taking off wet clothing and using items such as cotton clothing to keep warm, and secondly, you can take steps to ensure that the core areas of the body are warmed first—such as the chest, neck, head and groin.

When experiencing hypothermia outdoors, enter a warm room or residence immediately, take off wet clothes in time, take relevant measures to warm the core area of the body, take hot drinks to help raise body temperature but not alcoholic beverages, and seek medical attention as soon as the condition is relieved. Don't let yourself be overdrawn, prevent dehydration, and replenish body calories at any time.

In general, hypothermia is when the body loses more calories than it regains, causing a drop in core temperature and a range of symptoms such as chills, confusion, cardiopulmonary failure, and eventually death. There are two main causes of hypothermia. The first and most common cause is exposure to extreme cold.

Another reason is to be in any condition that inhibits the body's heat production or increases the rate of temperature loss.

As the saying goes, prevention is the best way to avoid risks. We must not only learn how to deal with hypothermia when it occurs, but also master how to avoid hypothermia, which is the most scientific and reasonable method. Temperature loss is mainly caused by the interaction of temperature, humidity, wind, and other major factors.

In order to avoid the risk of temperature loss, we need to work on these points.

<> terms of humidity, there are many people traveling outdoors, especially some equipment parties will always focus their eyes and attention on what clothes, down jackets, soft shells in the middle, and the precautions for outerwear (divided by the three-layer dressing method), visit the rain and snow, visit to keep warm, and ignore the risk of sweating a lot and may cause hypothermia; The selection and preparation of underwear was neglected. When doing outdoor activities in cold weather, it's important to stay dry! What are the precautions?

Hypothermia is when the body's ability to produce heat and keep warm is lower than its ability to dissipate heat for a long time, resulting in a body temperature that is getting lower and lower. In the cold and windy mountainous areas, when it is dark, you are still wearing soaked underwear, the clothes are not warm enough, there is no exercise after lying down, and the body heat production is lower than the heat dissipation, which can easily cause the body temperature to drop. The drop in body temperature depends on two factors:

The body's ability to produce heat and keep warm, the speed at which heat is lost, clothing cold, body surface cold, hunger, fatigue, old age and infirmity can all cause body temperature to drop. The main symptoms of hypothermia include feeling cold, cold limbs, constant shaking, paleness, memory loss, slurred speech, muscles not controlled by the will, unresponsiveness, personality changes or irrationality, slow pulse, and loss of consciousness.

Hypothermia describes the phenomenon when the body's core temperature is lower. to bring it into a warm room or shelter; Remove damp clothing; Warms the core areas of the body – chest, neck, head, and groin; Use hot drinks to help raise your body temperature, but don't take alcoholic beverages, and don't give them to people who are unconscious.

The temperature drop is more severe, and if there is no particularly sufficient food**, the body temperature will drop sharply, and then there will be memory loss; At this time, you can exercise more, be sure to improve your body's immunity, you can bite your tongue, and you can also eat something.

The temperature of the human body is constantly lost, and the outside temperature is very low, and people will die unconsciously. Be sure to move your body more, pay attention to keeping warm, and ask others for help in time.

Hypothermia refers to the rapid drop of human body temperature in a very short period of time, and people should try to use more warm items to stick to their armpits and feet when they encounter room temperature outdoors, so as to cope with room temperature.
