Under the high temperature environment, there are symptoms such as headache, dizziness, thirst, sweating, weakness and acid of limbs, inattention, uncoordinated movement, etc. Body temperature is normal or slightly elevated. If it is transferred to a cool and ventilated place in time, it can be recovered in a short time by adding water and salt.

In addition to dizziness and thirst, there are often manifestations such as flushing, sweating, burning skin, etc., or manifestations such as cold and damp limbs, pale complexion, blood pressure drop, pulse increase, etc. If it is handled in time, it can be recovered within hours.
3. Severe heatstroke symptoms
As the name suggests, it is the most serious case of heatstroke. If not treated in time, life will be endangered. This kind of heat stroke can be divided into four types: heat spasm, heat exhaustion, solar radiation disease and heat radiation disease.

This kind of heat stroke occurs when the muscles will suddenly appear paroxysmal spasm pain.

(4) Symptoms and characteristics of heat radiation disease: there are also some people who have been engaged in physical labor for a long time in high temperature environment, and the body produces too much heat, while the heat dissipation is insufficient, resulting in a sharp rise in body temperature. In the early stage of the disease, there was a large amount of cold sweat, followed by no sweat, shallow and fast breath, fine pulse, restlessness, vague mind, decreased blood pressure, and gradually developed into coma with limb convulsion; in severe cases, brain edema, pulmonary edema, heart failure, etc.
