The weather in summer is hot, and heat stroke is easy to occur if you are not careful. If heat stroke is not handled properly, it is very likely to be life-threatening, so it is very necessary to learn some emergency first aid for heat stroke. So what should you do if you suffer from heat stroke?

What exactly is heat stroke?

Normal human body temperature can be kept constant at around 37°C through the action of the hypothalamus temperature regulation center. The result of a balance between heat production and heat dissipation. When the ambient temperature exceeds the skin temperature, heat dissipation mainly relies on sweating and evaporation on the skin and alveolar surfaces. The heat dissipation of the human body can also be carried out by circulating blood flow, which brings the heat of deep tissues to the upper and lower tissues, and dissipates heat through the expanded skin blood vessels. Therefore, the more blood flow through the skin blood vessels, the more heat dissipation. If the heat production is greater than the heat dissipation or the heat dissipation is blocked, excess heat will accumulate in the body, which will cause high fever and heat stroke.

Heat stroke can be life-threatening if not handled properly, so here is an introduction to emergency rescue for heat stroke:

1. Get out of the high temperature environment and quickly move the person with heat stroke to a cool and ventilated place to rest. Make him lie down, head elevated, and loosen the buttons. If the situation is serious, you should call the 120 emergency hotline immediately.

2. Replenish fluids. If the person with heatstroke is conscious and has no nausea or vomiting, he or she can drink salty drinks, tea, mung bean soup, etc. to cool down and replenish blood volume. .

3. For artificial heat dissipation, electric fans can be used to dissipate heat, but do not blow directly at the patient to prevent colds.

4. Ice compress, or cold compress on the head. Ice packs should be placed on the head, armpits, groin and other large blood vessels (use ice cubes, popsicles, water ice cream, etc. put in a plastic bag, Seal it tightly), and use cold water or 30% alcohol to help lower the body surface temperature.
