The Hypothermia is characterized by decreasing temperature normal body which is 37 ° C to below 35 ° C. This sensation causes the individual to go into a process of tremor due to contractions of the blood vessels, which try to decrease the loss of heat by the body, thus keeping the body at a normal temperature. When the body does not have enough energy to control the process of hypothermia, it can lead to death.
Acute Hypothermia: It is characterized by the loss of body temperature, abruptly and rapidly, due to intense exposure to cold. This aggressive body drop is caused by the inability of the body to supply and maintain the internal energy due to the fact that it has cooled too. It is very common in cases of exposure to snow, storms, etc.
Subacute Hypothermia: It is characterized by the loss of body temperature, gradually, over longer periods until the total waste of the bodys reserves to supply the internal heat.
Chronic hypothermia: The most common in urban centers, especially in seasons such as winter, where the rate of colds and diseases happens more frequently. Chronic hypothermia is caused by the consequences of some pathology.
Hypothermia is caused due to intense exposure to cold in several ways, such as:
- In cold environments, when there is nobody warmth that is provided by clothing, protecting all members, including the head.
- Exposure to rain and cold winds. The contact of the water with icy breezes causes the body temperature to lower.
- People who have suffered an accident, who take certain types of medications, are likely to have hypothermia.
- Babies kept in cold environments are also able to have hypothermia if there is not a correct heating of their entire body.
The most common symptoms of hypothermia are tremors, the coldness of the hands and feet, numbness in the limbs, poor energy, difficulty breathing, slow heartbeat, swelling in the face, loss of bladder control. In later stages, hypothermia causes loss of memory, loss of control of the upper and lower limbs, loss of sensation, loss of heartbeat, and dilated pupils.
