Why heatstroke easily

summary

Now the weather is getting hotter and hotter, especially in midsummer, we need to actively prevent heatstroke to avoid affecting our health. Let's see why it's easy to get heatstroke.

Why heatstroke easily

One of the reasons: heatstroke is a group of clinical symptoms caused by body temperature regulation dysfunction caused by long-term exposure to high temperature environment or physical activity in hot environment, characterized by high fever, dry skin and central nervous system symptoms. The mortality of severe heatstroke was 41.7% when the core temperature was over 40 ℃, and 81.3% when the core temperature was over 42 ℃. Therefore, it is very important to take timely measures to solve the heat stroke.

The second reason: environmental factors in the high temperature workshop work, if coupled with poor ventilation, it is very easy to suffer from heatstroke; agriculture and open-air operations, direct exposure to the sun, coupled with the sun exposure on the ground, the atmospheric temperature rises again, so that people's meninges congestion, cerebral cortex ischemia and cause heatstroke, increased humidity in the air is easy to induce heatstroke.

The third reason: personal physical factors in public places, family, crowd concentration, heat concentration, heat dissipation difficulties, heat exhaustion, mainly due to lack of circulation around, resulting in collapse or transient syncope.

matters needing attention

Stop activity and rest in a cool, well ventilated environment. Remove excess or tight clothing. Let the patient lie down and raise the lower limbs 15-30cm. Wet towel can be placed on the head, armpit, groin, with cooling effect.
