Hyunda is on the hot search again, because of physical problems again.
Didn’t the sexy little Mustang just return to the music scene with her new song "Nabillera".
And this time we return together, the appearance and shape of the little wild horse, which is much more beautiful than the previous rural Samatt.
I didn’t expect to return for only 4 days and fainted in the studio while participating in the program.
It’s quite scary to see the details shared online.
"I often faint recently, and I am always dancing happily, but I suddenly fell down."
However, too many hot searches are inevitable to cause rebellion...
Hyuna has always had vagus fainting, and it is not the first time she often faints.
This time, it mainly returns to the compact itinerary and the recent continuous high temperatures in South Korea. Although it does have physical problems, it does have a little bit of "dreaming from heat".
Speaking of this summer, it was really hot this summer. According to statistics, the highest temperature of 71 weather stations broke through the historical highest value...
Moreover, it will only get hotter and hotter next.
Many friends have directly turned on the fire-free cooking mode.
However, among the many jokes of netizens, what shocked adults the most is that people are familiar with each other.
reminds adults of the past when they saw the stern heart Yutan was steamed...
Will our bodies be "ripe" in high temperature weather?
Generally speaking, when the temperature reaches 3℃.
We will feel hot, and the human body's "air conditioner" sweat glands will turn on the heat dissipation function , helping us dissipate heat by sweating.
If a friend stays at this temperature for a long time and doesn’t sweat at all, it may be because of skin heat dissipation disorder . In this case, you can go to the hospital to check the six hormones , and force the sweat glands to work by taking some endocrine-conditioning drugs.
When the temperature rises to 5℃, you may think that this temperature is also quite common in summer.
But in fact, this temperature is already very dangerous.
Meteorological The maximum temperature on the previous day reaches above 35℃, which can be called high temperature weather.
As the temperature continues to rise, we begin to experience what it means to really sweat and also to have a strong sense of thirst. At this temperature,
, normal people need to vent about 5L of sweat a day, and will also take away 15g of sodium and various minerals .
Blood will gradually become thicker, and the pressure on the heart will make us feel bored.
At the same time, the blood flow in the brain is also decreasing, you will be slow to react and easily get angry .
Wait until 8℃. Sweating alone can no longer maintain the normal body temperature of . All organs have to do their best to help our bodies cool down.
Our whole body will start to turn red, because The heart outputs 60% more blood than usual to the body surface and participates in heat dissipation .
You should know that every time the body surface temperature rises, the heart rate needs to adapt to 15 more times. At this time, the incidence of heart failure will increase by 1 times, and the mortality rate of heart disease will increase by 1.5 times.
If the weather reaches 0℃ or above , it will cause damage to the brain and other major organs, and may lead to loss of consciousness, such as the terrible heat stroke .
At this time, the sweat glands are basically exhausted, body temperature can no longer drop to the normal range , and we will feel dizzy, even the soles of our feet become weak, and we can't even stand firmly.
Major organs are also on the verge of failure , the blood flow of the skin vasculature increases, and the blood flow of the heart pumps from 5 liters per minute to 20 liters of .
tried to mobilize blood from other parts to reduce the skin temperature, but the heated blood flowed through the whole body, causing the body temperature to rise faster.
Faced with the sudden increase in temperature, almost all cells in the body will produce heat shock protein or stress protein to avoid damage caused by high temperature .
It’s a pity, it’s useless, vascular endothelial cells will still be damaged .
Because the increase in the blood discharge of the heart will also cause ischemia and hypoxia in other organs, triggers dysfunction of the central nervous system .
At this time, we are like steaks that are slow-cooked at low temperature.
protein in the body continues to degeneration, and various organs are damaged to varying degrees.
The result of blood is mobilized and the surface cooling is organ ischemia, which will continue to cause toxin outbreaks in cells until liver failure is triggered.
. In order to deal with these endotoxin , the body secretes a large amount of anti-inflammatory substances such as intercellular, which eventually triggers systemic inflammatory response syndrome .
Cytokine imbalance causes internal damage to the body, and The final result is Multi-organ failure death .
So, it is true that many netizens say that heatstroke will bring irreparable losses to our bodies.
Although some people will be out of danger after first aid, what we don’t know is:
There are also some people who will suffer from rhabdomyolysis, acute renal failure, acute lung injury and other complications within one or two weeks after first aid, and 30% of people will leave long-term neurological sequelae.
The heat we feel
much higher than the actual temperature
There may be friends who are curious, obviously the water at 40 degrees does not feel very hot.
Why is the weather at 40 degrees so difficult and even fatal?
Although we look at the weather forecast every day, the temperature of the weather forecast is actually just one dimension.
Our human body feelings will also be affected by other factors.
For example, humidity, high temperature and high humidity weather are simply a double blow to the human body.
This is the tolerance limit table of the human body under different temperatures and humidity.
You can see that as long as the humidity exceeds 50% at 0℃, the limit of human tolerance has reached .
Then let’s take a look at the humidity monitoring table released by the National Meteorological Information Center. Most of China’s humidity is generally blue-purple, and the relative humidity of actually reaches 60%~90% .
In addition to feeling uncomfortable in the body, the dual attacks of high temperature and high humidity will also affect the normal function of the body.
When the ambient temperature exceeds more than 75% of the relative humidity of the environment, the heat dissipation mechanism of the human body almost goes down.
If you do not cool down in time at this time and are still in a high temperature environment, the consequences will be terrible...
facing the terrible heat stroke
What can we do
To prevent heat stroke, we must first prevent heat stroke.
# Drink more water
In the matter of heatstroke, whether it is prevention or relief, the most important thing about is: drink more water .
High temperatures, you must increase your moisture intake at any time, and don’t wait until you are thirsty before drinking.
If you have sweated a lot, it is best to supplement the beverage containing electrolytes such as potassium and sodium to avoid dilution hyponatremia .
# Avoid high-temperature environment
Try to move indoors, even indoors Pay attention to opening windows for ventilation, and use electric fans, air conditioners and other electrical appliances to cool down .
When you have to go outdoors, it is best to ensure that you can drink 2 to 4 cups of water or electrolyte water per hour .
# Always pay attention to your own situation
Heat stroke does not appear suddenly, but gradually worsen.
If mild heatstroke occurs, such as excessive sweating, dizziness, chest tightness and shortness of breath, you must pay attention and deal with it in time to prevent the situation from worsening.
First find a cool place to rest immediately, keep the surroundings ventilated, and replenish moisture in small mouths many times.
If your family and friends are around you have heatstroke, First, carry the patient to a ventilated and cool place. If possible, you can use cold water to wipe the skin to accelerate heat dissipation . Patients such as
have become aware, and then small mouthfuls and replenish water or sports drinks multiple times.
If you have not recovered your consciousness, it is best to apply ice to the patient's neck, armpits and roots of the thighs to physically cool it to protect important organs such as the brain, heart and lungs, and send it to the hospital for treatment in time.
In such extremely high temperature weather, I hope that my friends can protect themselves and their families.
air conditioning fan, start it when it is time to turn on.
