Loss of temperature and first aid

What is the loss of temperature?

In simple terms, body temperature is lower than normal body temperature. We all know that a fever of 37.5 degrees or more, and a temperature of 39 degrees without a decrease in body temperature will become unconscious until death. The situation of loss of temperature is also similar. If the body temperature is below 35 degrees, people will lose consciousness and even coma.

What will cause loss of temperature?

In theory, as long as the ambient temperature is lower than the body temperature, it will lead to loss of temperature. The actual situation is that people who get adequate food supplements and are in good health lose a lot of body temperature when they lose 20 degrees. If it is 10 degrees, the temperature will soon drop to a loss of temperature.

In dry weather, the nude Kro is 0.78, which is basically the same as wearing a simple T-shirt.

However, the cold and rain will quickly take away heat.

In other words, even if the temperature is 20 degrees, the human body is exposed to the rain (no heavy rain or rain), which leads to a decrease in body temperature (the human body can quickly revert to questions by means of chills).

If it is at 10 degrees, the body temperature may rapidly decrease to a state of dehydration under the rain, and the body's recovery ability cannot compensate for the balance.

Loss of temperature performance:

1, chills

2, lips purple

3, blurred consciousness.

How to first aid:

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

2, quickly add heat. Internal calorie supplements: Drinking aqueous dextrose solution, replenishing hot water; External sources of heat: such as hugging and roasting.

The main pathological cause, when there is severe loss of temperature, the first symptom is the reduction of blood sugar, sugar is the root of calories, liver glycogen is not decomposed in time, and body temperature cannot be restored. Therefore, supplemental glucose can quickly restore its ability to warm up.

The supplement of hot water is to increase the temperature of the internal organs through the warmth of the stomach so that the internal organs can return to work. The heart supplies blood and the liver decomposes liver glycogen.

Avoid rubbing limbs, blood circulation will bring cold blood back to the heart, leading to cardiac arrest.

On a windy day, it may freeze and die at 10 degrees. On a heavy rainy day, it may freeze to death at 20 degrees. The clothes that are saturated with sweat are the culprit. Keeping your body dry is the primary issue, followed by the right time to add energy. Avoid sweat soaking clothes.
