It is unbelievable that the ability of the human body to endure

The maximum level that the human body can tolerate with heat, cold and pain through research makes us startled.

How tolerant the human body is

When human pain must be exclaimed, when the cold is shaking and the heat is sweating. However, the maximum level that the human body can tolerate with heat, cold and pain through research makes us startled.

Resistant to 160 degree C heat

Dr. Nguyen Y Duc (USA) said, like other animals, when born, the human being was given a very sophisticated system to regulate and keep the body temperature at a normal level. before sudden changes from outside or from the body.

This system gets the coordination of the hypothalamus parts in the brain and muscles. The average body temperature varies from 36.2 degrees Celsius to 37.6 degrees Celsius (ie from 97 degrees F to 100 degrees F). F-degree is used by US scientists, while most countries in the world use Celsius with 0 degrees of ice temperature, 100 degrees of boiling water temperature.

Our body temperature also varies depending on the time of day. Low morning because the body is not energized after a long night's sleep; The afternoon is higher because of the day's activities and the consumed food has created a lot of heat. The temperature measured in the lower armpit is lower in the mouth and mouth than in the anus.

Body temperature is always average thanks to the balance between heat generation and heat dispersion. Sunny is the light that brings the heat of the sun directly to Earth. Sunlight increases gradually from morning to high at noon and gradually decreases to evening and night.

Air temperature is often lower than the heat that we feel because of the influence of relative humidity. The higher the air humidity, the more uncomfortable you feel.

A performer dipped his hand in a pan of boiling oil.

Currently, our country has stepped into the hot summer, making people uncomfortable and giving birth to all kinds of diseases. However, according to Dr. Nguyen Y Duc, we should not be too worried but learn the secret to cooling the body .

Depending on the location and habitat that people can adapt. Normally, at a temperature of 50 degrees Celsius, we are suffocating. However, scientists who had been injected seven times to do the experiment increased the temperature slowly and found that humans could withstand up to 160 degrees Celsius , which is beyond the boiling point of water to 60 degrees Celsius.

To test this possibility, two British physicists have slipped into the toaster oven for several hours. The results were amazing when they survived. The conclusion is that in ideal conditions, the environment is dry, people can withstand temperatures as high as 160 degrees C. Why is that?

Dr. Nguyen Y Duc said: ' People have 4 heat escape mechanisms: radiation, conduction, convection and sweating. But when it is hot, 3 ways: radiation, conduction, convection will only increase the body temperature. At that time, the key is to stay in sweat. When sweat evaporates, they suck in the heat in the air area around the skin, causing this zone to have a temperature lowered below the body's temperature. '

It is heat resistant when the temperature increases steadily . As for the sudden heat, people suffer with a degree. The author of this article once witnessed the scene of Mr. Cao's Tay people making offerings on red charcoal, even dipping their hands into boiling water 100 degrees C but still withstanding even though the skin was burning.

How cold?

According to Dr. Nguyen Y Duc, people are aware of the cold that begins to form when the nerves in the skin send nerve impulses to the temperature of the skin to the brain. These nerve impulses not only react to the skin's temperature but also react to the rate of skin temperature changes.

Therefore, we feel cold when jumping into cold water compared to when we have been in cold water for a certain period of time. It is adaptive and this has attracted many people around the world to try to see what temperature the body is exposed to.

Wim Hof, 53 years old from the Netherlands, has 8 cold records.

The story of Mr. Wim Hof, 53 years old from the Netherlands, has 8 times set a world record for superhuman cold tolerance that has proved it. This man can take a walk on the North Pole with a cold temperature of -20 degrees Celsius, dive deep in the ice more than 80 meters with a normal swimsuit and climb to the top of Everest, only wearing a pair of shorts. He also took a dip in a 1.5m high stone tank with a time of 1 hour and 12 minutes.

However, the human body will be damaged and lead to death due to cold or blood loss or inability to circulate. If people suffer from a cold wind of -9.4 degrees C, then there will be stiffness. But the air temperature below the freezing point of 0 degrees C is already numb.

Pain also has genes

Unlike the 'threshold of tolerance' of heat and cold, the ability of humans to endure pain is caused by scientists. There are people who suffer very well, can even suffer pain in the 'red threshold' , which can lead to death.

But some people suffer very badly. These people, when they have a needle in their hands, will be hurt by a good pain sufferer who stabbed the abdomen. Therefore, the ability to endure pain each person is different.

Scientists found four pain-related genes called COMT, DRD2, DRD1 and OPRK1. Through a survey of more than 2,700 people prescribed drugs containing drugs to cope with chronic pain, require patients to self-score pain scores from 1 to 10 in mild to severe levels and then divided into 3 groups.

9% of people who self-identify with low pain; the group with average pain accounted for 46% and the group with high pain felt 45%. People with DRD1 have less pain. For moderate pain groups, the two genes COMT and OPRK1 are more common. Meanwhile, the DRD2 gene is more common in people with a lot of pain.

The ability to endure human pain depends on the psychological and belief factors . This is evidenced in the political prisoners that the French colonialists and American imperialists invaded Vietnam and arrested and tortured.

Political prisoners, for their ideals and beliefs, should be able to withstand the "red threshold" of torture. Usually, ways to make people suffer extreme pain such as: Sawing teeth, piercing red iron bars into skin or beating bones will cause victims to die. However, because of a certain belief that they easily overcome, even feel less painful.

'The human body is a masterpiece of creation. In particular, the body can adapt to all conditions, from hot, cold to painful feelings. Of course, there are also "red thresholds" that make people fall. But with the maximum human tolerance at 160C, not every creature can do it. '
