Symptoms of hypothermia include trembling of the body, a changing heart rate at rest, and slight confusion in the head. The danger increases when the trembling stops and the heart rate decreases. Your usual temperature drops sharply, which indicates a slowdown in chemical reactions in the body. And it can lead to death.

No specific external temperature, at which hypothermia necessarily occurs, has not been established. It all depends on:

The wind.
Insulating properties of clothing.
Body fluid level.
Degrees of physical fitness.
Body fat percentage.
The power of exposure to moisture.

Since water is an excellent conductor of heat, moisture on the skin or even near it will remove it from the body.

When hypothermia occurs, when the body loses heat faster than it can produce it, the first symptoms of hypothermia appear:

Body temperature drops to 35 degrees.
When the body tries to warm itself, trembling begins
Resting heart rate increases.
Breathing quickens.
There is some confusion in thoughts.

If the above symptoms occur, immediately put on additional layers of clothing or remove wet and put on dry. Do not lie on cold ground, make litter from vegetation or other available materials.

If there are warming thermal packs, chemical heating pads or other sources of heat, put them under your armpits, on the neck or in the groin, where the arteries pass. Before body temperature is restored, do not use them on your arms and legs. Warming the limbs will cause an increased rush of blood to the heart, which can lead to its arrest. The body, in order to save resources for performing basic functions, sacrifices limbs, restricting blood flow to them.

With the development of hypothermia, with a decrease in body temperature, the condition worsens:

Body temperature drops to 29 degrees and below.
Tremors stop.
Heart rate decreases.
Breathing faints.
Loss of consciousness.

Avoid alcohol, caffeine, and nicotine, which cause blood vessels to dilate and increase heat loss. With a more severe form of hypothermia, emergency care of another person is required. The introduction of an aqueous solution of sugar, mouth-to-mouth breathing, or other primary resuscitation in the field helps.
