Knowledge of heatstroke prevention at home heatstroke.
It's not just the high temperature
What is heatstroke?
To put it simply, the heat of the human body can't be dispersed, and it accumulates in the body in large quantities, resulting in dysfunction of the thermoregulatory center, dizziness, dizziness, palpitation, chest tightness and other symptoms, and even coma in severe cases.
Professor Zhan Hong, director of the emergency department of the First Affiliated Hospital of Sun Yat-sen University, said that direct sunlight and high temperature are important causes of heatstroke in the hot summer, but in addition, many people actually ignore the other two factors: high humidity and insufficient ventilation.
In my impression, such accidents often happen to old people, especially those who have just arrived in Guangzhou. It is often difficult for them to adapt to the climate here, and they feel wet and hot, which makes people upset and fidgety.
Weak people and children may suffocate if their thermoregulatory center is not perfect. As for the pregnant women on hot days, if they stay in a closed room for a long time, the possibility of heatstroke is higher.

Performance is divided into three categories.
Experts pointed out that according to the degree of illness and performance characteristics, heatstroke can generally be divided into three categories.
● Threatened heatstroke:
It is characterized by thirst, dizziness, tinnitus, chest tightness, palpitation and weakness of limbs. Sweating is not much, body temperature may rise slightly, and fever may be around 37.5℃. If you can get rid of the high heat environment in time, the symptoms will disappear after a short rest.
● Mild heatstroke:
There are not only symptoms of threatened heatstroke, but also symptoms such as redness and burning of the skin, accompanied by nausea, vomiting, sweating, wet and cold skin, and decreased blood pressure. Fever often reaches 38.5℃. People with mild heatstroke can generally return to normal within 4-5 hours after treatment.
● Severe heatstroke:
Most cases are sudden coma in high temperature environment. In the past, I often had headaches, numbness and tingling, dizziness, irritability or insanity, and limb convulsions. My skin is hot and red, and my temperature is often above 40℃.
