A person who is not dressed for the weather may develop hypothermia in the cold. This word is called a state when a person's internal temperature drops below 35 degrees. The dangers of its development are most susceptible to the elderly and people under the influence of alcohol.
Hypothermia is mild (when the temperature drops to 32-35 degrees), moderate (28-32 degrees) and severe (below 28 degrees).
On average, the temperature of a person's body in the cold drops by about 1-2 degrees in 30-40 minutes.
With a mild degree of hypothermia, when the internal temperature drops to 35 degrees, severe tremors begin, and reactions slow down.
After another hour or so, the body temperature will be 34-33 degrees. The person no longer trembles, because the body has practically no energy left, the poor man who finds himself in the cold begins to lose his memory and reason.
After the body temperature drops below 33-32 degrees, a state of apathy sets in, and then a stupor. In this state, a person from the outside looks lifeless: the skin becomes pale and cold, arms and legs stop bending, breathing and other life processes slow down. But a person can still be saved.
When the internal temperature drops to below 25 degrees, blood circulation and respiration stop and the person dies from hypothermia.
And here I became interested in what I needed to change in the body of my genetically modified people so that they could be without clothes for a long time at temperatures below - 20-30 ° C, and for several hours at temperatures below - 45 ° C, which can be seen in Antarctica and the Arctic?
Note: These superhumans must not be covered in hair.
