Live Wilderness Adventure - Chapter 687 winter swimming

On the cleaned ice surface, white cracks that spread like cobwebs can still be clearly seen, and this river, which is completely covered by ice cracks, exudes an amazing chill.

Bi Xianglai is a man who dares to think and act. To the surprise of the audience, he took off all his clothes, leaving only a pair of shorts.

The cold wind was still cold, and when it was blown by the cold wind, the capillaries naturally reacted physiologically, shrinking rapidly, reducing the heat that escaped from the outside. Bi Fang felt like he was wrapped in a blanket of ice like needles.

Let alone swimming, normal people need a lot of courage to go into the water.

Every breath makes people feel uncomfortable. The icy cold air pours straight into the lung cavity from the throat, as if every alveolus is condensed with a layer of frost at low temperature, but compared to being exposed to the cold wind, the next action will be more piercing.

It has been more than two weeks since I came to the North Pole, and the time has entered from mid-October to November. For people in most areas, this time is not too cold, but once it rains, wearing a shirt is not enough. Yes, I can already feel a little chill.

Seeing what Bi Fang was doing at this time, many people shrugged their shoulders subconsciously, goosebumps all over their bodies, as if the person standing on the screen and being blown by the cold wind was themselves.

Especially from the first-person perspective, when looking at the whitened ice surface, the coldness almost overflows, and it is suffocating.

[Mass, I feel like my teeth are chattering. 】

[Every time I see those people swimming in winter, I suspect that they are aliens]

[Is it really not going to freeze to death? 】

It was raining lightly outside the window, and a cold wind blew into the office with a slight chill. Even though he was wearing a coat, Yao Jun couldn't help shivering and put down the cold drink in his hand.

Good for you.

Yao Jun wrapped his jacket tightly, and involuntarily asked him to take out his phone and flip through the contact list.

Tonight's night is extraordinarily cold. He needs a big sister who has a broad mind and can warm people's hearts to watch the live broadcast together.

Ordinary audiences can only bear the tears alone.

[Too fierce, Fang Shen is so high! 】

【What is a macho (tactical leaning back)】

[Let me use my sincere heart to warm the ice! 】

Bi Fang held his breath and did not choose to jump directly into the ice from the shore, but walked up barefoot.

No one knows how strong the ice surface is. Although there are cracks, if it doesn't break open and jumps on it, a slippery foot may cause the **** to bloom.

Under the low temperature, his feet quickly turned red, Bi Fang shuddered, and then walked gently. When he came to the middle of the river, the cracking sound of the ice surface sounded again, like a cracker.

Tiny ice chips burst out along the huge crack, and when it was about to reach the limit, Bi Fang tiptoed slightly, and finally gave a forceful meal, and the entire ice surface collapsed.

"Wow."

The clear water splashed up and down on the ice surface, quickly forming a layer of frost.

The silver bubbles filled the whole world, and Bi Fang resisted not closing his eyes.

The blood vessels seemed to have ice thorns flowing through them, further coagulating and expanding at low temperature, puncturing the elastic blood vessels.

A gloomy poisonous snake wrapped around the spine along the tailbone, soared up at an extremely fast speed, and entrenched in the depths of the brain.

Like an electric current flowing through, his body almost instinctively wanted to open his mouth to breathe, but he was abruptly covered, but in the end he inevitably swallowed a mouthful of water.

The thermal conductivity of water is 30 times greater than that of air, which means that in water, the body dissipates heat 30 times faster than in air at the same temperature.

Fourteen degrees Celsius of cold water, the body temperature is already zero.

Ten degrees Celsius of water, the body temperature is minus four degrees Celsius.

Eight degrees Celsius is the cold feeling temperature for winter swimming. The body sensation is just the opposite. It is minus eight degrees Celsius, giving people an extreme feeling of strong cold, tingling, pain and numbness.

Most of the natural waters will start to freeze at four degrees Celsius, and the body feels minus sixteen degrees.

3°C water temperature feels -20°C.

2°C water temperature feels -24°C.

1°C water temperature feels -28°C.

The water temperature of 0℃ is below -30℃.

In the North Pole, under the temperature of minus tens of degrees, the frozen river is undoubtedly the last gear.

The biting cold almost cracked Bi Fang's mouth, but the cold water flowing down his throat calmed him down.

The normal winter swimming is undoubtedly to be warmed up, to expose oneself from a comfortable temperature, to wake up every cell and every pore of the body to adapt to the cold, but Bi Fang did not, because while swimming in winter, he also had to By the way, I will demonstrate the survival of falling into the water.

Without acting rashly, Bi Fang sank quietly in the water, and the silver bubbles that caught his eye slowly disappeared.

【Why don't you move? 】

[There will be no accident, right? 】

[I heard that anyone who falls into cold water will be stimulated by cold water to produce trunk reflexes, which will make you constantly hyperventilate, cause your heart rate to rapidly increase, and may cause short-term shock. Lao Fang is not in shock, right? 】

[Fangshen, Fangshen, are you still there? Fangshen, just blink when you can see it]

You can't even see it in the blink of an eye.

Bi Fang couldn't help but complained.

The first-person camera has an intelligent recognition function, which can complete the picture by itself. Blinking all the time does not affect the viewing angle of the audience at all, unless the eyes are directly closed.

But in the face of the audience's worries, Bi Fang still gave birth to five fingers and scratched, and made an OK gesture, indicating that there is no problem with himself, and there is still consciousness.

This made many viewers breathe a sigh of relief, everything was fine, but Bi Fang's motionless posture still caused everyone's doubts. UU reading www. uukanshu.com

Why don't you act?

But Bi Fang didn't make everyone wait too long. The first moment of entering the water was undoubtedly the biting cold, and then there was an instinctive desire to breathe.

Therefore, those who fall into the water must control their breathing and avoid panting, and after a brief cold, they have to face the danger of hypothermia.

Once excessive hypothermia, it will also face life-threatening.

After the initial cold is over, the blood has to flow back and expand, sending out a steady stream of heat, the glycogen in the body begins to decompose in a large amount, and a huge amount of oxygen is consumed at the same time.

But Bi Fang felt that he was feeling better at this time.

Under the condition of being completely still, Bi Fang can last under water for more than eight minutes, which is quite a terrifying value for normal people. On the contrary, it is also Bi Fang's physique that continues to improve, insist on training, the maximum Very exaggerated results for oxygen uptake.

It's just that in cold water, the blood flows at a high speed for heating, and the time will undoubtedly be reduced, but three or four minutes is still very easy, but even so,

After feeling that his body was no longer so biting, Bi Fang started to move. He first looked up, but found that the cave where he fell into the water had disappeared for some time.

The audience's scalp suddenly went numb.

Bi Fang was swept away by the river!
