Since the beginning of summer, the weather is really too hot, although this year there is a lot of rain, but it has not played a cooling effect, but the temperature has also risen continuously.
According to reports, in the high temperature weather of close to 40 degrees Celsius in the south of China, a middle-aged man living in Huizhou, Guangdong Province, died recently because of severe heat stroke and because of ineffective rescue after being sent to the hospital.
A Man from Guangdong died of severe heat stroke
When the man was first admitted to the hospital, the doctor took his temperature once, and after a very surprising experience, the man's body temperature was nearly 42 degrees Celsius, which can be said to have reached the limit.
At the same time, due to severe heat stroke and high body temperature, his heartbeat also reached 139 beats per minute, you know, normally speaking, the heart rate range is 60 to 100 beats per minute as a normal standard, which shows how fast the man's heartbeat is. In addition, his breathing is 28 times per minute, which is also very rapid, because for normal people, about 12 to 20 breaths a minute is normal.
Naturally, in this terrible state, the man eventually died because the rescue was ineffective. So, why do people suffer from heat stroke? Once you have suffered heat stroke, how to rescue it?
Why do people suffer from heat stroke?
First of all, the most direct cause of heat stroke, is that the ambient temperature is too high, in general, when the temperature rises to more than 30 degrees Celsius, people will feel sweltering, at this time, if you work outdoors for a long time, and there is no relevant heat relief, protective measures, it is easy to have heat stroke.
In addition, if it is outdoors engaged in strong physical labor, or itself is in a sub-healthy state, or even suffers from some diseases, in the case of outdoor high temperatures, it also belongs to the people who are prone to heat stroke, because they are too obese, or the physical condition is not good, which will lead to poor body heat dissipation, which is easy to increase the body temperature, resulting in heat stroke.
Moreover, everyone should not feel that if you do not go out in the summer, there will be no heat stroke, you know, even if you are indoors, even if you are blowing a fan and air conditioning, you will also suffer from heat stroke.
Especially from the very hot outside back, suddenly into a very cool environment, this time, because the body suddenly changed from hot to cold, that is, the temperature of the body suddenly dropped significantly, at this time, it will also lead to sudden death of the body due to sudden cooling.
In addition, if the indoor ventilation environment is not good, or if you have stayed indoors for a long time, suddenly entering a sweltering environment from a cool environment, you are also prone to heat stroke.
How can I tell if I've had heat stroke?
Generally speaking, even if the heat stroke is mild, the most common reaction is to feel dizzy and weak, and then feel nauseous, want to vomit, and the body will sweat a lot, at this time, generally only need to go to a cooler place, some heat relief measures, basically do not need to go to the hospital, and soon can recover on their own.
The other is the severe heat stroke suffered by the Huizhou man in the above article, which is also a very dangerous situation, because at this time, the body temperature will often exceed 40 degrees Celsius, and it will continue to rise, as if when the man was taken to the hospital, the body temperature has reached 42 degrees Celsius.
At this time, basically has completely lost consciousness, into the state of "hot fainting", but also into the endangered state, under the influence of the human body's high temperature, basically the body's organs have begun to fail, it is very difficult to rescue back.
How many people die of heat each year?
Although there are no people around us who have been "heat death", this does not mean that "heat death" is very far away from us, on the contrary, if the protective measures are not good enough in the summer, in fact, it is possible to suffer from heat stroke at any time, and even "hot fainting".
Take this year, many places are not receding from high temperatures, 2021 has also become one of the hottest years in history, taking North America, the number of people who have died due to high temperatures has reached nearly a thousand, and because the current high temperature is still not dispersed, this also means that the number of deaths will continue to rise in the next summer.
In addition, in other countries, there will be deaths due to heat every year, and with the continuous deterioration of global warming, researchers also said that if the global average temperature in the future will really rise by 1.5 degrees Celsius, then the "heat death rate" of humans at that time will increase to about 48.8-67.1 people / million people, that is, about 60 people will be heat death in the average 1 million people.
And if the average temperature of the earth rises by 2 degrees Celsius, then the human "heat death rate" will reach an average of 1 million people, 80 people will be heat death, it can be said that this data is already very terrible, which also sounded the alarm for human beings, warning us that if we do not stop global warming, it may be really too late.
