★ Symptoms of threatened heatstroke
In the high temperature environment, there are symptoms such as headache, dizziness, thirst, sweating, weakness and pain of limbs, inattention, uncoordinated movements and so on.
Body temperature is normal or slightly elevated.
If it is moved to a cool and ventilated place in time and supplemented with water and salt, it can be recovered in a short time.
★ Mild heatstroke symptoms
The body temperature is often above 38 degrees.
In addition to dizziness and thirst, it is often manifested as flushing, sweating, burning skin, etc., or cold limbs, pale face, decreased blood pressure and accelerated pulse.
If handled in time, it can often be recovered within a few hours.
★ Symptoms of severe heatstroke
As the name implies, it is the most serious type of heatstroke, and it will be life-threatening if it is not treated in time. This kind of heatstroke can be divided into four types: heat spasm, heat exhaustion, heatstroke and heatstroke.
Characteristics of symptoms of heat spasm: it mostly occurs when the concentration of sodium chloride in blood drops rapidly and obviously due to excessive sweating and thirst, excessive drinking water and insufficient salt supplementation. When this kind of heatstroke happens, the muscles will suddenly have paroxysmal spasmodic pain.
Symptoms and characteristics of heatstroke: this kind of heatstroke mostly occurs in the elderly and people who can't adapt to the high temperature for a while. The main symptoms are dizziness, headache, palpitation, thirst, nausea, vomiting, cold skin, decreased blood pressure, syncope or confusion. At this time, the body temperature is normal or slightly higher.
Symptoms and characteristics of heatstroke: The cause of this kind of heatstroke is just like its name, because under the direct irradiation of the scorching sun, strong sunlight penetrates the skin and skull of the head and causes brain cell damage, which in turn causes brain tissue congestion and edema; Because the main injury is the head, the initial discomfort is severe headache, nausea and vomiting, irritability, and then coma and convulsions may occur.
Symptoms and characteristics of heatstroke: Some people have been engaged in manual labor in a high temperature environment for a long time, and the body produces too much heat, but the heat dissipation is insufficient, resulting in a sharp rise in body temperature. At the beginning of the onset, a lot of cold sweat broke out, followed by no sweat, shallow breathing, rapid pulse, restlessness, confusion and decreased blood pressure, which gradually developed into coma with limb convulsions; Severe cases can produce brain edema, pulmonary edema, heart failure and so on.
