How to prevent heatstroke? What should I do if I get heatstroke?
Heatstroke is a disorder of body temperature regulation under the influence of high temperature, which is often caused by exposure to hot sun or heavy physical labor in high temperature environment.

Heatstroke and high fever, that is, a lot of heat accumulation in the body. People suffering from heatstroke will have drowsiness, coma, flushing, dry and hot skin, no sweat, shortness of breath, increased heart rate, decreased blood pressure and high fever, and their body temperature may exceed 40 degrees.
Heat exhaustion means that there is not a lot of accumulated heat in the body. People suffering from heatstroke may have pale face, cold skin, weak pulse, shallow and rapid breathing, syncope, coma and blood pressure drop.
