What is heat stroke and what are its symptoms?

Everyone has finally begun to pay attention to this disease. In fact, this disease has always been unknown in China because the victims are mostly manual workers and poor people.

The temperature in Jinan reached 40 degrees Celsius in June; Hunan actually issued dozens of high temperature warnings on July 10; Shanghai also detected the highest temperature since 1873... This year’s breakthrough In the summer with record high temperatures, people began to learn about heat stroke collectively.

Heat stroke cases of fainting and even death have appeared in Jiangxi, Xi'an, Guangzhou, Zigong, Zhejiang and other places.

What people often say in summer is "the heat is killing people", but it really happened. There are workshop workers who fell down at work, and there were also grandmothers who died from taking a nap at home.

When it comes to heat stroke, we must talk about heat stroke. This is a concept that everyone knows. It means that in an environment with high temperature or humidity and no ventilation, due to problems with the body temperature regulation function or sweat glands, Functional failure leads to massive loss of water and electrolytes, leading to acute diseases in which central nervous system and cardiovascular function are abnormal.

There are three types of heat stroke.

The first is premonitory heatstroke, which refers to symptoms such as profuse sweating, weakness, dizziness, and thirst when people are exposed to high temperatures. At this time, as long as you leave the high temperature environment and replenish salt water or sports drinks in time, you will be able to return to normal soon.

The second is mild heatstroke, which is based on precursor heatstroke. The symptoms will worsen, and the body temperature will gradually rise above 38°C. Symptoms such as burning skin, clammy limbs, and accelerated pulse will occur. But it is easy to handle, just remove it from the high temperature environment.

The third is severe heat stroke. This type of heat stroke is divided into three levels, namely heat cramps, heat exhaustion and heat stroke.

Heat cramps mostly occur in young adults. When these people train, exercise, or work in a high-temperature environment, they will experience short-term muscle twitching. The change in body temperature is not too obvious and can be relieved by replenishing energy in time.

Heat exhaustion often occurs in the elderly, children and chronically ill people. Because the weather is very hot, excessive sweating will cause the body to lose a lot of water and salt. If it is not replenished in time, symptoms such as dizziness, dizziness, and vomiting will occur. If the air humidity is high at this time, it is very dangerous for children and the elderly.

The most serious form of heat stroke is heat stroke, which is divided into exertional and non-exertive forms.

The meaning of exertion can be understood literally. When we perform strenuous physical activities, we will definitely sweat a lot, the heart rate will increase rapidly, and the body temperature will rise to 40°C, followed by intravascular coagulation. , there are problems with the function of multiple organs.

Non-exertional symptoms mainly refer to environments with high temperature, high humidity, and poor ventilation. Due to incomplete or weak development of the central nervous system, people such as children and the elderly are susceptible to non-exertional symptoms. Sexual heat stroke.

Exertional heat stroke patients sweat a lot. Most patients with non-exertional heat stroke do not sweat, but their body temperature can reach above 46°C.

When one's own temperature control is out of balance, symptoms such as confusion and coma are likely to occur. If left unchecked, it may lead to heart failure and kidney failure.

High body temperature will occur regardless of labor or non-labor. Once the temperature is not lowered in time, multiple organ failure such as kidney failure and liver damage will occur, and it will worsen quickly and the mortality rate is also very high. High, according to statistics, it is between 20% and 70%. This is why heat stroke is scary, so you must be alert to the changes after heat stroke, because the most fundamental cause of heat stroke is actually the body's inability to control temperature due to heat stroke, and the temperature cannot be lowered, causing a series of symptoms.

Finally, let me tell you a simple solution, because I have had heatstroke, but it was dealt with promptly and nothing serious happened. At that time, I found something was wrong, dizziness and fever, but not It was so serious that I immediately bought a bottle of iced mineral water. Then I sat in the shade for a while, opened my clothes, and put the mineral water on my head. Needless to say, I was fine soon.

Everyone should remember that if symptoms of heatstroke occur, you must leave the high-heat environment in time. If you find that the symptoms are not relieved after cooling down, you must call 120 in time without delay.

High temperature weather may continue in most areas for some time to come. Everyone must pay attention to sun protection, drink more water, and avoid going outdoors if possible.
