Frostbite, classifications and how to avoid it in the mountains

Frostbite, classifications and how to avoid it in the mountains: recommendations from the mountain guides of the French university, STAPS.

In the mountains, a person is exposed to several factors that cause them to fight the cold. Violation of heat exchange may occur due to weather conditions, improperly chosen clothing or incorrect behavior. Each body radiates and loses heat due to infrared radiation. This is what my blog is about today.

A few reasons and ways to combat the cold:

The body cools down from the bottom, but the heat comes from above (“if you have cold feet, put on a hat”).
Evaporation of a drop of water consumes calories. Sweating does not cool the body if there is no evaporation.

“Stay dry = stay alive”

The intensity of air cooling increases with the speed of the wind (“always protect yourself from the wind”).
The higher – the cooler. Rising every 100m, the temperature around drops around 0.6°C. Do not wait until it freezes.
Isothermal point in air: 25°C
Isothermal point in water: 37°C

Thermoregulation

Temperature is the balance between thermolysis (heat loss) and thermogenesis (a reaction that produces heat in response to physical exercise and thrills). A person must maintain a temperature of about 37°C. It is this temperature that the main organs require – the brain, the heart, the large vessels, in order to function properly.
