The marathon in Gansu province brought the word "temperature loss" to our eyes. A fresh life passed away like this, and the occurrence of the event deserves our deep thought.
In fact, when it comes to hypothermia, many people don't know what hypothermia is, and they don't know that hypothermia can lead to death.
What is temperature loss?
Loss of temperature means that when the heat loss of the human body is greater than the heat supply, the temperature in the core area of the human body will drop to 35.0℃, which will cause symptoms such as trembling, confusion, cardiopulmonary failure, and even death.
Temperature loss can be divided into mild temperature loss, moderate temperature loss and severe temperature loss.
1, slight temperature loss:
The patient's body temperature drops 1~2 compared with the normal body temperature, and at the same time, it will produce trembling, numbness of hands, fatigue, abdominal pain, cold limbs, pale face, uncontrolled muscles, emotional changes or loss of reason, weak pulse and so on.
2. Moderate temperature loss:
The patient's body temperature dropped by 2~4 compared with normal body temperature, and the symptoms of chills gradually disappeared, and he was slow and difficult to move, accompanied by stumbling, disorientation and mental disorder.
3. Serious temperature loss:
The patient's temperature dropped below 32, and he lost consciousness and entered a state similar to hibernation. The specific manifestations are that the muscles are no longer spasmodic, the pulse and respiratory rate are slowed down, the blood circulation on the body surface is greatly reduced, and consciousness is lost. At the same time, due to severe hypothermia, there will be abnormal undressing. At this time, the patient begins to undress, which will increase the risk of cardiac arrest.
Why is there a phenomenon of temperature loss and death in summer?
The human body transfers heat with the outside world at any time, among which temperature, humidity and wind are the most common factors leading to temperature loss. No matter summer or any season, there will be a temperature difference in the morning and evening. Marathon is a long-term exercise, of course, it will cause people to sweat more, so the humidity will increase accordingly. If the wind increases, it is easy to dissipate heat quickly, leading to a drop in temperature, not to mention the bad extreme weather.
How to prevent temperature loss?
1, choose the right underwear
In addition to rain and warmth, you should also pay attention to the risk of temperature loss caused by a lot of sweating. Therefore, you should choose underwear that is quick-drying and perspiring, and be careful not to choose cotton underwear, because cotton absorbs sweat and is not easy to export, thus causing temperature loss.
2. Pay attention to increasing or decreasing clothes
When exercising in cold weather or extremely cold areas, be sure to carry warm clothes with you, and then stick a T-shirt with light and quick-drying fabric or add a coat with good permeability to avoid getting cold and losing temperature.
3, pay attention to cold and warm.
When traveling in cold weather, you should take corresponding windproof measures and don't be completely 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.
4. Replenish the energy needed by the body in time.
Don't let your body overdraw, mainly to prevent dehydration and avoid excessive sweating and fatigue. Prepare food and hot drinks to replenish body heat at any time.
