Effect of low temperatures

Under the effect of low temperature on the body there are a number of General and local reactions. The occurrence and severity of General and local reactions at cooling depends on the ambient temperature, the air speed, humidity, condition of the thermal protection of the organism (the nature of the service), the degree of hydration of the skin, individual characteristics and condition of the body. Sick, malnourished people, the elderly, children are the most vulnerable to the cold. Rapid cooling of the body contribute to anemia, injury, fatigue, emotional turmoil. Of particular importance in the development of cooling has the effect of ethyl alcohol, because when drunk peripheral blood vessels dilate and therefore increases heat dissipation.
In addition, the state of alcoholic intoxication, and reducing distorting subjective assessments, deprives people of the opportunity to perceive the danger of hypothermia. Hypothermia in 33 % of all observations occurs when the temperature from 0 to + 5 degrees C. Especially not tolerate low positive temperature from 5 to 8 degrees of newborns due to the underdevelopment of the heat-regulating reactions and significant prevalence in the ratio of body surface above the mass.

  • General cooling
  • Local action cold (mad)
  • Checklist
    1. Describe ways of non-lethal effect of low temperature on the human body.
    2. Give a description of the pathogenesis of death due to hypothermia.
    3. How to explain that in cases of death from hypothermia cadaveric spots can be pink or purple?
    4. List the characteristics that are diagnosed on the body in cases of death from hypothermia:
    a) at external examination;
    b) when the internal investigation.
