Why do people suffer from heatstroke? What should I do after heatstroke?

Under the control of hypothalamic thermoregulation center, normal human body is in a dynamic balance of heat production and heat dissipation, and its body temperature is maintained at about 37℃. When people exercise, their metabolism accelerates and their heat production increases. The human body transfers the heat generated in the body to the body surface by means of skin vasodilation, accelerated blood flow, increased sweat gland secretion and accelerated breathing, and dissipates heat through radiation, conduction, convection and evaporation, so as to keep the body temperature within the normal range. Heatstroke is in a high temperature or poorly ventilated environment. Due to the effect of pyrogen, the energy in the body is difficult to be emitted by radiation, conduction and convection, which leads to heat storage in the body, thus causing heatstroke.

Specific measures after heatstroke are as follows:

1, avoid heatstroke environment, and the sun should avoid the scorching sun;

2. Drink plenty of water;

3, drink diluted electrolyte drinks, pulse, red bull can be;

4, to supplement salt, drink light salt water;

5. avoid drinking alcohol;

6. Drink less things containing stimulating caffeine;

7. In case of heatstroke, usually smoke less;

8. If you want to work in a high temperature environment, you can gradually go to a higher temperature place and then to a high temperature environment, so that you can gradually adapt to the changes in ambient temperature and avoid heatstroke;

9. In the case of outdoor sports activities, you should slow down your activities. If it is hot, you can flush the places where the heat is concentrated, such as the head, neck and joints with more blood vessels in the limbs. In the process of water evaporation, the body temperature may also drop. Heatstroke can collapse in a few days, and the weight of collapsed patients can plummet. At this time, if patients find that their weight has dropped significantly, they should be more alert to heatstroke. If you want to be outdoors, you can wear a hat to avoid heat absorption. In the case of heatstroke, we should be careful not to absorb more radiant heat. Breathable clothes, such as undershirts, have the effect of cooling off summer heat. Some traditional Chinese medicines are also helpful for heatstroke, such as ten drops of water and Huoxiang Zhengqi liquid. If you want to do outdoor activities, you can prepare yourself.
