What are the reactions of human beings when faced with extreme low temperatures?

When human beings are faced with extreme low temperatures, the swimming water begins to freeze in winter, and humidity and temperature will occur, muscles will tremble, the body will also tremble involuntarily, the frozen parts will be very painful, the metabolic level will be reduced, and then a feeling of heat will be produced.

Hypothermia will occur, muscles will tremble, and there will be involuntary trembling, pain will be felt in the frozen area, the metabolic level will decrease, and there will be a feeling of heat.

There will be an illusion of being very hot, all clothes will be taken off, there will be trembling, there will be confusion, there will be blood freezing.

When human beings are faced with extreme low temperatures, if they do not receive effective rescue, there is only one final result, that is, they will freeze to death。There will also be a process of extreme low temperatures, for example, you may feel mild hypothermia at the beginning, and you will feel mild discomfort. Mild room temperature: Generally speaking, people feel the temperature.

It is around 37 degrees Celsius, and if the temperature drops to about 35 degrees Celsius, then it will be a mild hypothermia. In this case, people will feel cold, their hands and feet will be a little numb, and they will not be so flexible, but this situation can be effectively controlled, and it is not very serious.

When the temperature continues to drop below 35 or 33 degrees, people can feel a noticeable chill。At this time, it may lead to tooth fighting, or the body will experience a certain amount of fatigue, and the brain will also be affected by this, and it will send out a state of sleep and hibernation. This moderate loss of points is actually more dangerous, if it cannot be improved in time, it is likely to lead to serious consequences, and if it is not well controlled, it is easy to fall into a state of coma.

In the case of extreme low temperature, to the last stage, then when the severe humid temperature temperature is 33 degrees or lower than 30 degrees, it is still the ultimate hypothermia. If the environment is relatively cold and the temperature will continue to drop, then the person's consciousness will become blurred, and the body will be able to feel numbness in addition to trembling, and it will not feel cold, and the ability to move will basically be lost. Because of the extremely low temperatures, the brain produces a type of dopamine.

and some other substances that cause hallucinations. Most of these hallucinations are associated with something beautiful, so many people who freeze to death are mostly smiling, which is also caused by hallucinations in extremely low temperatures.

In life, we must not go to some places that are too cold, even if it is to participate in some sports or travel, we must understand the local climate and matters to pay attention to, so as to avoid serious consequences due to cold.

Human beings will hallucinate when they encounter extreme low temperatures, at this time they will feel very hot, they will take off their clothes, the body's metabolism will be very fast, the water in the body will be frozen, and the body will shake unconsciously.

The human body will feel very cold, the hands and feet will be numb or stiff, the body will tremble, and the consciousness will begin to become blurred.

With the advent of summer, there are different degrees of high temperature warnings in many places, and even the high temperature records in some places are constantly being broken, and the frequent occurrence of high temperature weather has brought different degrees of impact on people's life and health.

1. The highest temperature that human beings can withstand is 35 of the wet-bulb temperature, and it is more common to exceed 35 in summer, and this temperature is also within the range that humans can bear. Usually the thermometer that measures the temperature mainly includes the consideration of humidity and temperature, and when the temperature is reached, it is a particularly high temperature.

2. Under normal circumstances, 25 30 is the most comfortable temperature for the human body, and it is no problem for a healthy person to stay in a high temperature of 50 for two hours, and can stay in a high temperature of 70 for 15 minutes, and can stay in a high temperature of 100 for a minute, and if you stay in a high temperature of 45 for an hour, then people will have heat stroke and even coma.

3. In fact, when the high temperature reaches the range accepted by the human body, it is often accompanied by high humidity, and there is no accurate range of how many degrees of high temperature can be borne by human beings, mainly according to the different differences in the physique of different people, some people's physique is relatively poor or when they suffer from certain diseases, the ability to regulate body temperature is relatively poor, and the temperature they can withstand will be relatively low.

Fourth, the current high temperature weather is difficult to sell in a short period of time, high temperature weather will pose a threat to people's health, human physical conditions are also limited, not to say that the climate is hot, human beings can bear it, high temperature weather occurs frequently, human body is also unable to bear.

In the season of frequent high temperatures, we must do a good job of preventing heatstroke, especially people with poor physique or people who are fat, we must avoid working for a long time in a high temperature environment, drink more water, eat more vegetables and fruits, and pay attention to preventing heat stroke.

The limit of the high temperature that humans can withstand is 80-90 degrees Celsius, which is still in a dry environment, and if it is in a humid environment, then it can withstand up to 50-60 degrees Celsius.

I think the highest temperature that human beings can withstand is about 50 degrees, after all, the temperature of 50 degrees is already unbearable, and if it is higher, it may lead to heat death.

I think it's 50 degrees because the highest temperature in the Arab region is 50 degrees right now, and it's killing people and animals.

The maximum and minimum temperature values that a person can tolerate are called the maximum temperature range and the minimum temperature range, and the range limit can be changed by exercise, and there is no fixed value.

For the first year of junior high school, please ask everyone. Thank you.

There is a limit to low temperatures, absolute zero, which is minus degrees Celsius.

Hello, A460-i7If the heat dissipation is not good, the CPU will be downclocked when it reaches 85 degrees, and it will automatically shut down when it reaches more than 95 degrees.

Some experts in the United States believe that people are flesh and blood after all, so there should be a limit to the extreme temperature that people can tolerate, and this limit may exceed 200In order to prove that his own point is correct, they cite many examples. For example, in the summer in central Australia, the local people can tolerate temperatures of 40 to 55; On the route from the Red Sea to the Persian Gulf, the temperature that passengers on passenger ships can tolerate is 50

People living in the Death Valley area of California, United States, the temperature they tolerate is 57In addition, data from tolerance tests conducted by scientists are cited: for example, at ambient temperatures of 104 and 104, the human body tolerates 1 hour, 49 minutes, 33 minutes and 26 minutes.

In these experiments, humans tolerated an extreme temperature of 106

However, there are some scientists who disagree with them. These people say that humans can tolerate more than 106 temperaturesFor example, the French scholar Professor Tillette claimed to have witnessed a woman spend 12 minutes in a stove with a high temperature of 132.

British scientists Prague King and Gentry also claim that they themselves spent several minutes in a 160-day bread oven. One Belgian claimed that he himself spent 200 minutes in 1958!

At present, the record of heat-resistant temperature is being broken all the time. The vast majority of people believe that there will be an end to this record. However, what people are most interested in is not the temperature itself, but the principle of heat resistance.

We hate the heat of summer, but we are afraid of the cold of winter, and some people even die because of the heat or cold. In the course of human evolution, we have never relied on the ability of the body alone to overcome temperature, so in a cold and hot environment, which one will make humans die faster? Which of these two extremes kills more humans?

When the body temperature is higher than 37 degrees, it will make people feel uncomfortable and even weak, and when the body temperature is above 40 degrees, if you cannot get timely medical treatment, it may even cause death. Once the body temperature exceeds 42 degrees, then most people will die from the heat. Therefore, the international definition of weather with temperatures greater than or equal to 35 degrees or more is a high temperature day, and the death caused by high temperature is mainly divided into two types, one is death from dehydration, and the other is suffocation.

For example, in the desert, because the air is dry, the high temperature will cause the water in the body to evaporate quickly, and if there is no timely replenishment of water, it will soon cause dehydration and death. And if it is in a humid environment, the humidity in the air is too high, which will prevent the natural heat dissipation of the human body. When you can't resist the heat by perspiring, it only takes ten minutes for your body temperature to exceed 40 degrees.

Excessive heat can cause vital organs in the body to stop working and eventually die of heat. According to statistics, in hot weather, if there is no protection, people working under the scorching sun for six hours will be life-threatening.

About 17 times as many people die from cold as from heat every year, do you know why? The Guinness Book of World Records is the most tolerant person to the cold is Wemhoff from the Netherlands, who has been challenging the cold since he was 17 years old and has set 21 world records so far. Most notably, he once soaked in a glass box filled with ice and ice water for 120 minutes, which is the current limit of human resistance to cold, when his body temperature may have been less than 30 degrees.

Know that the lowest temperature on a mercury thermometer is 35 degrees. If the human body temperature is lower than this temperature, then the most basic memory and thinking abilities will be lost, the muscles will begin to spasm, contract, and even pain, the beating of the heart will begin to slow down, the volume of the heart is only 2 3 large, and when the body temperature drops to degrees, the brain will be unable to work due to insufficient blood supply to the heart. I think most people understand what this means, brain death is irreversible.

As a result, no one understands why Wimhoff was able to keep his body temperature around 30 degrees for two hours. You know, the average person jumps into a glass box filled with ice and cold water, loses consciousness in 30 minutes, and dies in 60 minutes.

Extreme cold is more likely to be disappointing because hypothermia occurs, and these people will lose consciousness and have a state of fantasy that they have no way to control.

The low temperature of -100 degrees Celsius is more lethal than the low temperature of -100 degrees Celsius. Through research, it has been found that the human body can survive in a high temperature environment of 100 degrees Celsius for 10 minutes, and can survive in a low temperature environment of minus 100 degrees Celsius for an hour.

According to relevant statistics, the number of deaths from high temperatures is only about one-twentieth of the number of deaths from low temperatures. The core temperature of the human body is in between, and it should be noted that the core temperature of the human body is not the body surface area with obvious changes. When the outside temperature drops, the blood vessels on the surface of the body will constrict, trying to retain heat and maintain the core temperature.

Ambient temperature limit: approx. 116

Solution: This is the temperature at which the human body can still breathe while in the midst of it.

Scientists have experimented on the highest temperature that the human body can tolerate in a dry air environment: the human body can last for a full 1 hour in an environment of 71; At 82 hours, it can last 49 minutes; At 93 hours, it can last 33 minutes; At 104, it only lasts 26 minutes. However, according to the relevant literature, the extreme temperature that the human body can tolerate seems to be higher.

Minimum body temperature limit: approximately.

Solution: This is the result of testing. In 1994

A 2-year-old Canadian girl named Kari Kosolovski was locked out of her door for six hours, and it was said that the outdoor temperature was 22 at the timeIn the end, the little girl was lucky to save her life, except for one left leg that had to be amputated due to frostbite.

It can shorten the time it takes to leave, and it will taste good.

It is recommended to give it a try.
