What is hypothermia? How to deal with hypothermia outdoors?

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.

The Gansu Marathon incident was caused by hypothermia, which killed and injured 21 people, which shows how terrible hypothermia is; However, there are also some first aid or self-help methods for hypothermiaThe first is to move the hypothermic person to a safe place, then isolate the hypothermic person from the ground, then change the patient's clothes, and dry the body of the hypothermic person, wrap the hypothermic person with a sleeping bag or thick clothes, and finally warm the hypothermic person, but be careful not to give the hypothermic person to drink hot water to avoid low blood pressure caused by a large amount of low temperature blood circulation.

Although hypothermia may have a small chance of occurring for people who don't like outdoor sports, it is still very helpful to know more about this knowledge, such as this Gansu Marathon, which is caused by bad weather to cause hypothermia, so it is necessary to prevent it from happening.

You should stop exercising immediately and call for help, change into dry clothes, put on a jacket to keep warm, and preferably drink some sugary drinks, or some hot sugar water.

When you lose temperature, you should find a thermal blanket around you to wrap yourself, hide in a leeward place, and eat some liquid and high-sugar, warm food.

First of all, you need to reduce calorie loss, you can add clothes, and increase the amount of activity. Then eat and replenish water, carbohydrates, proteins and fats. Ignite a fire or use body temperature to help the person rewarm.

You should rub your hands, don't let yourself stop, let the temperature rise as soon as possible, keep hazing, and exercise to generate heat.

Keep it dry, it's easy to sweat during exercise, and the body dissipates heat 25 times faster when you sweat than when you are dry, so be sure to keep your body dry. It's best to choose quick-drying clothes to wear underneath and warm clothes when resting.

How can I treat people with hypothermia around me? First of all, if someone falls into the water and causes hypothermia, take off his clothes in time and change into warm clothes. When the person is not unconscious, let him keep his body moving.

If possible, feed the person some warm sugar water.

If we experience hypothermia, we should stop exercising, but we should also find a place where the constant temperature is very warm, and wait for our body temperature to recover. Hypothermia is when the temperature on the body passes quickly, and there is no way to get it back.

Hypothermia is when the body loses more heat than it produces, which is hypothermia. When you encounter hypothermia, you should quickly find all ways to reduce the loss of body temperature.

What is hypothermia and how do we deal with hypothermia? Learn about these first aids.

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.

Self-help for hypothermia.

When hypothermia occurs, there will be unstable movements, decreased coordination, decreased consciousness and control of the whole body, and even fainting. At this time, you should stop exercising and call for help from the ambulance force in time. At the same time, you should change into dry clothes and put on a coat or insulated aluminum foil to find shelter.

Supplement with sugary sports drinks, preferably if there is hot sugar water.

Rescue Steps: Step 1: Safe Transfer.

In many cases of hypothermia deaths, the victims were exposed to harsh environments that caused hypothermia. At this point, outdoor activities should be stopped immediately and the patient should be moved to a sheltered place behind shelter such as rocks. Set up tents for rescue if necessary.

Step 2: Cold surface isolation.

After the patient is safely moved to a sheltered place, the cold ground will continue to eat away at valuable heat, and the second step of the rescue team is to quickly isolate the patient from the ground with a sleeping mat to prevent the patient's core body temperature from continuing to lose. Because heat is conducted from hot objects to low temperatures, the role of the sleeping mat is to block the ground and slow down the heat conduction process.

Step 3: Drying.

When the patient develops hypothermia, he or she may have been hiking in the snow and wind for a long time, and the inner layer of clothing has been wet; Outside rain and snow can also wet clothes. The rescuer should help the patient change clothes as soon as possible, dry the patient's body with fabric, keep the patient's body dry, and wrap the patient's whole body with a sleeping bag or thick clothing.

Step 4: Warm up the core area.

When the patient's hypothermia is severe, the consciousness will be blurred, and the muscles will no longer tremble, which also means that the patient's body has lost the ability to heat the body, at this time, it will not help to put it into the thick warmer, and can only be externally heated for the core parts, such as using hot water bottles and heating patches to warm the patient's neck, armpits, groin and other core areas. It is wrong to warm the limbs.

Note! Do not attempt to warm the extremities or drink hot water in people with severe hypothermia, as the return of large amounts of cold blood to circulation and further lowering of blood pressure and temperature increase the risk of resuscitation failure.

How can I prevent hypothermia?

Prevent hypothermia. Pay attention to the choice of underwear. People who travel outdoors mostly focus on rain and snow protection, and only care about keeping warm, and ignore the risk of hypothermia caused by heavy sweating. Choose fast-drying underwear that wicks sweat, not cotton underwear. Cotton fabrics are very sweat-absorbent and do not easily export and cause hypothermia.

Pay attention to the addition and removal of clothing. Keep warm clothes in your carry-on bag before hiking in alpine areas, and wear a light, quick-drying T-shirt or a breathable jacket when you set off. Take out warm clothes and put them on at every rest point to avoid catching a cold and hypothermia.

Pay attention to warm protection. If you travel in cold weather, you should take appropriate wind protection measures and do not expose yourself to cold winds. Warm hats, gloves, neck scarves, windbreakers, thick socks, and windproof masks are all essential items for traveling in windy and cold weather.

Replenish physical energy in a timely manner. Don't allow yourself to overdraw, prevent dehydration, avoid excessive sweating and fatigue. Stocking up on food and hot drinks to replenish your body calories at all times.

If the human body is hypothermic, it is necessary to seek help in time, get out of the environment as soon as possible, and use the surrounding items to save yourself.

Hypothermia is due to the fact that the heat flow of the human body is greater than the heat supply, resulting in a decrease in the core temperature of the human body, hypothermia is a very dangerous state, which will lead to a decrease in the coordination of human movements, a decrease in control, confusion, and continuous hypothermia can lead to cardiopulmonary failure and even death.

When the human body is in a state of hypothermia, it is necessary to stop exercising immediately and call for help in time. In the process of waiting for ambulance, it is necessary to get out of the hypothermic environment in time, find a shelter, and give up dry clothes, wrap a jacket tightly or insulated aluminum foil, and drink some sugary functional drinks or warm sugar water if possible.

Patients with hypothermia should move to a dry and leeward place, avoid exposing the patient to humidity and windy environments, pay attention to not letting the patient lie directly on the cold ground, take off the patient's soaked underwear, and do a good job of keeping the head warm and cold. Mild and moderate hypothermia phases:

1. You only need to change into dry clothes and block the wind and cold;

2. If the injured person can eat, he should be allowed to eat some liquid food as soon as possible, and then eat a little sugary food;

3. Wrap the hot water bottle in gloves or socks, and then put it on the armpits, neck and groin of the injured person;

4. If these are not enough to restore the body temperature of the injured person, it is necessary to ask a warm teammate to relieve the patient by direct physical contact in the case of a sleeping bag or other dry isolation object.

The disease is mainly to prevent further heat loss, increase body temperature, prevent and treat complications, if the patient's vital signs disappear, urgent cardiopulmonary resuscitation is required until the body temperature returns to normal. So, how to first aid in case of hypothermia?

1. It is necessary to reduce the decrease in body temperature as soon as possible, leave the wind and rain, and change dry clothes.

2. Quickly replenish calories. Internal caloric supplement: drinking aqueous glucose solution, supplementing hot water; External heat sources: such as hugging, roasting.

The main pathological cause, when there is severe hypothermia, the first symptom is a decrease in blood sugar, sugar is the source of calories, and if the liver glycogen is not decomposed in time, the body temperature cannot be recovered. Therefore, glucose supplementation can quickly restore its ability to heat up. Supplemental hot water is to warm the stomach to raise the temperature of the internal organs, so that the internal organs can return to work, the heart provides blood supply, and the liver breaks down liver glycogen.

3. Do not rub your limbs, as blood circulation will bring cold blood back to the heart, leading to cardiac arrest. On windy days, 10 degrees may freeze to death; On a rainy day, 20 degrees may freeze to death. Sweat-soaked clothes are the culprit, keeping your body dry is the number one concern, followed by fueling at the right time.

Avoid sweat soaking through your clothes.

Quickly remove the patient from the cold.

Change cold and wet clothes, wrap the body in blankets or bedding, and adopt gentle passive rewarming for the patient; If the patient's temperature is 33 degrees, active peripheral rewarming is taken, including warming the patient's entire body with a hot water bottle or immersing the patient in warm water at 44 degrees.

Oxygen, hydration, and warming.

Doctors use warm oxygen and fluids to raise the room temperature. If the hourly increase in deep body temperature is insufficient, doctors may take proactive deep body temperature rewarming measures, such as enemas and gastric lavage.

Dialysis, hemodialysis, and bladder irrigation.

1. Eat sugary foods.

2. Change dry clothes and move to an environment with low air circulation.

3. Use a hot water bottle to put it in the palm of your hand or on the soles of your feet, armpits, neck and groin, and it is easy to warm up quickly 4. If necessary, people with warm bodies can use direct contact with their bodies to conduct heat 5.

First of all, it is necessary to strengthen warmth, and secondly, it is necessary to move the hypothermic person to a warm place as soon as possible.

The most important thing for hypothermia is not to let yourself hallucinate, and you must keep the best belief that you can rub your body or move.

You should go to your local hospital immediately for acceptance** and recover early**.

Immediately seek out the source of fire and avoid cold and wet environments.

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.

Loss of temperature, how to rescue safe transfer. At this point, outdoor activities should be stopped immediately and the patient should be moved to a sheltered area, behind rocks and other shelters. Set up a tent for rescue if necessary.

Cold face isolation. Sleep pads are used quickly to isolate the victim from the ground and prevent further drops in core body temperature. Dry.

<> when a patient has symptoms of hypothermia, rescuers should help the patient change clothes as soon as possible, dry the patient's body with a cloth, keep the patient dry, and wrap the patient's whole body with a sleeping bag or thick clothing. Heating the core area. At this time, only external heating can be carried out on the core area, such as using hot water bottles and hot compresses to heat the patient's neck, armpits, groin and other core parts.

It is wrong to heat the limbs.

Note! In severe cases of hypothermia, do not try to warm your limbs or drink hot water. Hypotension and further drop in temperature caused by massive cold-blooded return circulation increase the risk of unsuccessful rescue.

Hypothermia can be divided into mild and severe hypothermia. Mild hypothermia, when the patient's body temperature drops to 33 35, there will be severe chills, cold limbs, paleness, severe fatigue, slurred speech, loss of muscle control, drowsiness, memory loss, mood changes or loss of reason, slow pulse, hallucinations, etc. In severe hypothermia, the patient's body temperature drops below 32, the patient loses consciousness and enters a state similar to hibernation, which is manifested by the loss of muscle spasms, slow pulse and breathing, and loss of consciousness.

In severe cases, vital signs are lost. In this case, don't give up on the rescue easily.

The basic principle of hypothermia is to help the patient maintain their body temperature while helping the patient produce their own heat to restore their body temperature. If the patient is shaking, he or she is able to rewarm at a rate of about 2°C per hour. When participating in outdoor sports, people should adjust their clothing to changes in temperature and bring warm clothing if necessary.

When participating in high-intensity outdoor training, you should choose appropriate hats, gloves, socks, emergency clothes and other equipment; At all times, attention should be paid to conserving energy, preventing excessive fatigue and dehydration, and replenishing energy in time.
