The cold is not an assistant in the human body. Even a moderately fragile frost under certain circumstances can be very dangerous and even catastrophic. And the role here is not only the air temperature but also the wind speed. With a wind of 12-14 m / s and the temperature of -2 ° C, your body feels cold at -20 ° C. With the same effect, wind speed and total cooling are equal to -24 ° C. Experienced physicians, who often look after frostbite patients, should remember that not only the chest, but also the limbs, face, and head need heat that people do not always care about.
However, the nature of our body is such that all forces in an extreme situation focus on the protection of vital internal organs. And when a person falls into extreme cold conditions, the peripheral vessels and capillaries shrink to give heat to the heart, liver and others. As a result, legs, hands, face, and ears are in the most unfavourable position. During the cold season, therefore, waterproof warm shoes with high soles, gloves, a hat and a scarf should be your obligatory properties.
On the eyes
The organs of vision are among the most vulnerable to freezing. To a certain extent, the protective functions of the body to treat the onset of negative temperature, regardless of the attempt to raise the temperature of the eye with frequent tearing and the glands of the lacrimal and even repeated blinking, but the body has its limitation. So, if you’re actively involved in winter sports, like walking in the tundra, where snowstorms are not ruled out, it’s best to wear special goggles to protect your eyes from the negative special effects of cold on them.
If you also consider the wind, which increases the effect of low temperatures, you can also deal with the freezing of the cornea. In addition, the wearer of the lenses does not forget to accurately freeze the eyeballs. A good scarf is that when the temperature drops suddenly and quickly, it can be wrapped around the face and inhaled through it, keeping the skin and eyes warm for a long time.
Different Grades of frostbite on body parts
There are different grades of frostbite. Therefore, for simply walking the audacity or oversight, your hands can stay red for a week and need at least the cold and oily cream. On a long walk, you have a second grade of frostbite that does not turn red but is covered by bubbles of transparent liquid. And there is no way to dispense with a doctor except online assignment help UK, and the traumatized members must be treated within two weeks. The third grade is expressed almost in the same way, but with more tangible consequences and scarring at the freezing points. But when the skin is almost blue and marble motifs appear, it is really serious. In this case, the frozen parts of the body are distorted or severed for life.
The impact of frostbite on body temperature
The normal body temperature is 36.6 ° C. The decrease of the level of 1.6-4.6 ° C causes protective reactions and the person starts to breathe and shake more often. The body tries to stay warm in intensive mode, there is an intense loss of energy due to what one can perceive as fatigue.
