Dr. Leander Sloane, emergency coordinator of the Hospital Universitario Austral, explained that the heat stress the body temperature rises above 40 º C and can cause neurological disorders such as delirium, convulsions and coma. “
Children and the elderly, those most affected.
The actual incidence of this disease is unknown, but an epidemiological study conducted in U.S. urban areas averaged 20 cases per 100 000 inhabitants, was quoted as saying the paper “Heat Stroke” published in 2002 in the New England Journal of Medicine. The same analysis said, “Is increasing the threat of heat stroke due to global warming and heat waves are occurring in temperate areas.”
The most affected are children and people over 65 years. “Also those who are located in a low social status and those with chronic diseases,” added Dr. Sloane.
What happens when body temperature rises?
Our normal body temperature of 36 º or 37 º C is given by the internal metabolism and environmental temperature. When the carriage 1, activates heat receptors on the skin that send information to the hypothalamus, the center responsible for coordinating the endocrine system and responsible for thermoregulation. It responds by increasing blood flow to the skin, which causes sweating. If the surrounding air is saturated with moisture, the sweat evaporates and cools the body.
When the body cannot maintain this thermoregulatory alterations start local and then systemic, leading to a “heat stress, poor irrigation of organs, impaired immunity and intestinal barrier. This leads to “heat stroke.”
Often the onset of tachycardia and hyperventilation (rapid breathing), and decreased blood pressure. If the disease progresses they begin to alter the organs: kidneys, liver, lung, pancreas or heart.
Warning symptoms and how to act
some of the symptoms that can reveal heat stroke are headache, fatigue or weakness, intense thirst, nausea or vomiting and muscle cramps. “When in doubt, should take the temperature of the individual. If I were above 40 ° C, we must move to a cold environment, get your clothes and start the body cooling with cold packs on the neck, armpit. It can get into a bathtub, cold drinks and plenty of give and rushed to hospital, “Dr. Sloane listed. He added that if the victim’s temperature should not exceed 40 degrees, but if I had any of these symptoms, as should be moved to a medical facility. The fever reducers showed no benefit for this problem.
