Daily Evolution from Mastering Tai Chi-Chapter 215 - 204: -180°C

As the Cold Therapy Pod gradually took effect.

Wang Ye's body also began to slowly feel that extremely astonishing chill.

The principle of this Cold Therapy Pod is to use liquid nitrogen as the cold source, lowering the chamber's temperature through nitrogen vapor to between -110℃ and -180℃.

It utilizes intense, short-term cold stimulation on the surface of the human body for stress-induced cryotherapy, prompting the brain to signal blood flow back to major organs, aiding the recovery of the nervous, circulatory, and energy supply systems.

It has effects and functions such as skin care, immune regulation, alleviating insomnia and anxiety, reducing inflammatory response, enhancing muscle strength, and accelerating muscle repair, applicable in medical treatment, sports rehabilitation, and beauty shaping fields.

Even for an Olympic champion with excellent physical fitness, staying in such an extremely low-temperature Cold Therapy Pod can last at most 2-3 minutes.

Because under such extreme cold stimulation, blood vessels become very narrow, blood flow slows down, and the athlete's body becomes extremely painful, as if steel needles are pricking the skin all over.

Moreover, after leaving the Cold Therapy Pod, blood vessels expand to four times their usual size, circulating more oxygenated blood throughout the body, allowing damaged or overworked tissues and joints to heal. Hence, it's said that staying in the Cold Therapy Pod for three minutes can burn 800 kcal, equivalent to the total amount of energy consumed by Running 10 kilometers in 60 minutes.

In just the blink of an eye,

The Cold Therapy Pod quickly dropped to minus one hundred degrees Celsius.

Even Wang Ye's physique at this point felt a cold enough to make his teeth chatter.

In such a low temperature, an ordinary person would not feel anything special just by staying for three minutes.

They might even find it somewhat enjoyable, as this brief cold is not fatal, merely providing a novel and thrilling sensation, much like bungee jumping. Imagine, bungee jumping with a safety rope, compared to cliff jumping with no safety equipment, can these really be compared?

But if an ordinary person stays in the Cold Therapy Pod for more than five minutes, their limbs start to numb.

Meanwhile, the body begins to feel a strong burning sensation.

Staying for over ten minutes, the speed of blood flow slows infinitely.

Until it freezes.

Just like the frozen sleep chambers depicted in science fiction movies.

In just a few brief minutes, those inside the frozen sleep chambers become thoroughly frozen and lose all vital signs.

When the ice and snow thaw, only then do those in the frozen sleep chambers wake up.

Yet at this moment, Wang Ye's body merely shivered slightly, goosebumps forming all over. He did not experience an intense stinging pain, rapid breathing, or accelerated heartbeat like an ordinary person would in a perilous situation.

"Currently, the perceived temperature is about 0-5 degrees Celsius."

Wang Ye squinted slightly.

Minus one hundred degrees Celsius looks terrifying.

But in fact, after being blocked by the Biological Force Field.

It truly brought Wang Ye only less than half its power.

Then further countered by his fifty-fold metabolism and resistance to temperatures over 60℃. 𝙛𝒓𝓮𝙚𝔀𝒆𝒃𝓷𝒐𝓿𝙚𝓵.𝙘𝒐𝒎

The final perceived temperature he felt was at most around zero degrees.

This indicates he should still easily withstand lower temperatures.

After all, even ordinary people can endure temperatures around zero degrees for several hours.

At this moment.

Outside the Cold Therapy Pod, the assembled coaches began to whisper among themselves.

"I haven't tried the Cold Therapy Pod yet, will such low temperatures really not cause frostbite?" asked a coach nearby.

"Have you heard of the Leidenfrost effect?" Li Weimin said in a deep voice.

"Never heard of it, what does it mean?" that coach asked in confusion.

"The Leidenfrost effect refers to when a liquid does not wet a hot surface but instead forms a vapor layer upon it. When liquid nitrogen encounters extreme heat, it forms an insulating gaseous protective layer."

Li Weimin explained slowly, using the professional knowledge he knew:

"Human normal body temperature is 37℃, while liquid nitrogen is at -196℃. Upon entering the Cold Therapy Pod releasing liquid nitrogen, the temperature difference reaches 230℃. According to the Leidenfrost effect, at this moment, liquid nitrogen vaporizes into gas, forming a protective layer between the human body and nitrogen vapor, preventing frostbite."

The coach suddenly understood and said, "So, the human body is not actually in direct contact with the nitrogen vapor, but is protected by this layer?"

Lü Jinyi also showed a sense of enlightenment, saying, "No wonder I didn't feel anything special last time I stayed in the Cold Therapy Pod at -120℃ for two and a half minutes, there was a protective layer."

Another coach nodded thoughtfully, saying, "I saw a video before where a blogger touched liquid nitrogen with a bare hand. At the time, I thought it was an effect, but now it seems they relied on this protective film for brief isolation from the cold."

"That's right, but this protective layer doesn't last very long." Li Weimin rubbed his temples and said solemnly, "Therefore, staying in the Cold Therapy Pod for more than three minutes presents a risk of frostbite."

As their conversation ended.

The real-time temperature above the Cold Therapy Pod had already reached -170℃.

And by this point, dense smoke had erupted from the gaps in the Cold Therapy Pod.

The smoke is vapor emitted from liquid nitrogen, carrying a bone-chilling cold.
