Human reaction at high temperature

　　three3℃-sweat glands start to start. After working at this temperature for 2 to 3 hours, the sweat glands of the human body "air conditioner" will start to work, and the accumulated body temperature will be emitted by sweating slightly.

　　35℃-the heat dissipation mechanism reacts immediately. At this time, the skin sweats slightly, the heart beats faster and the blood circulation accelerates. For some elderly people with poor heat dissipation, it is necessary to cooperate with local cooling. This is the starting temperature of indoor air conditioning.

　　36℃-human body "self-cooling", level 1 alarm. At this temperature, the human body "cools itself" by evaporating sweat to give off heat. About 5 liters of sweat is discharged every day, which can take away 15 grams of sodium, 50 grams of vitamin C and other minerals, and the amount of blood solubility is also reduced. At this time, we must pay attention to supplement drinks containing salt, vitamins and minerals to prevent electrolyte disorder.

　　38℃-multiple organs participate in cooling, and the second alarm. Once the temperature rises to 38℃, it is difficult for the human body to maintain normal body temperature by sweating through sweat glands. Not only does the lungs "gasp" to exhale heat, but even the heart has to speed up and output 60% more blood to the body surface than usual to participate in heat dissipation. At this time, cooling measures, cardiac drug health care and treatment should not be relaxed at all.

　　39℃-sweat glands are on the verge of failure, and there is a three-level alarm. Sweat glands work hard, and they are powerless and tend to fail. At this time, it is easy to have a heart attack.

　　40℃-the brain pays attention to one thing and loses another, and there is a four-level alarm. The high temperature has reached the center of life, and the brain has lost sight of one thing, making it dizzy and unstable. At this time, people must immediately move to a cool place or use the air conditioner to cool down.

　　41℃-a life-threatening shock temperature. Sweating, breathing, blood circulation … All the organs that can participate in cooling are close to a spent force after full horsepower. At this time, life is in danger, and emergency rescue is urgently needed. For the frail elderly, this is a shock temperature that shakes the foundation of life.
