645 Hold your breath

It's not easy to hold your breath for a long time, and it takes a long, hard training process.

Fortunately, although Su Qin is not a member of the Marine Corps, he has not served in the Navy before, and he has not conducted special breath-holding training, but he has been practicing the Su Jiaquan Internal Martial Arts Method, and he also meditates every day later.

Before holding his breath, Su Qin poured a little cold water on his face.

Studies have found that when a person's face touches cool water, it triggers a slow pulse, or lowers the heart rate, which is a diving reflex in mammals.

Subsequently, Su Qin began to concentrate and use a special method to breathe as deeply as possible, inhale oxygen into his body, and store it in his blood!

Still, breathing like that isn't enough.

When you hold your breath, your lungs feel pressure, and your body will feel very uncomfortable, but this is not a signal that you need to breathe, but that carbon dioxide increases and needs to be released.

Over time, the carbon dioxide produced can make the pain feel worse until it becomes unbearable.

In order to minimize the carbon dioxide, Su Qin needed to expel the carbon dioxide originally stored in the lungs before holding his breath.

So he exhaled forcefully to expel the air from his lungs as much as he could.

As soon as he exhales completely, he inhales.

Breathe while staying still and avoid using up previously stored oxygen.

Everything was ready, and Su Qin began to sink into the water.

In order to hold your breath for a longer period of time, it is important to learn to inhale as much gas as possible, and second, to overcome the fear of oxygen shortage!

Prolonged breath-holding can be painful, so you need to find a way to distract yourself and overcome your fears!

A common distraction technique is to sort by first letter A to Z, thinking of friends, celebrities, or historical figures. The famous magician David Blaine set a world record of 17 minutes and 4.4 seconds of underwater breath-holding, and it was because of this technique that he used.

Also, don't put gas in your cheeks.

This method is called gas storage, which involves "expelling" the air from the lungs and replacing it with air from the cheeks. This is also known as "circular breathing", which is difficult for ordinary people to do and can cause gas to leak from both sides, so it is best not to use this method.

But if you learn it, you can give it a try, and Su Qin happened to learn this method.

After going deep into the water, Su Qin began to relax and began to meditate, breathing in a special way.

Click, click!

The hands on the stopwatch walk quickly and powerfully.

Shore.

The group was silent, just watching silently.

It was very strange that so many people were gathered here, so after a while, more and more people poured over, and in the end, someone simply went back to the dormitory and shouted: "Hurry up, hurry up, there is a recruit who is holding his breath in the water to play, even the political commissar is alarmed!" ”

"Really?"

"Really, I heard you want to challenge our record?"

"What? A rookie eggie who wants to challenge our underwater breath-holding record? When many veterans heard the news, their eyes widened in shock!

"Where are the recruits? So unbelievable? Someone came back to his senses and questioned.

"I heard it's a recruit from Group 7?"

"Seven groups? The seven groups are not ........", but the latter words were swallowed back.

"Brothers, let's go, go and see!"

"Let's go! Look at these soldiers of the new seventh group! ”

"Let's go!"

It wasn't long before more soldiers rushed to the swimming pool.

When I came to the pool, many people screamed "", and there were people everywhere in a huge swimming pool, and it was black.

"How long?" Someone pulled the person in front of him and asked.

"It's been ten minutes!"

"Ten minutes?"

A few veterans, you look at me, I look at you, and they are all surprised.

The soldiers of Unit 233 are indeed more powerful than the soldiers of many troops, and they can generally hold their breath for more than ten minutes, but the recruits are ...... Except for those from the navy, it is rare to reach ten minutes.

"Which unit is this soldier from?" Someone asked curiously.

"I heard it's troops from the southwest?"

"Southwest? There's no sea there! ”

"yes, that's why everyone thinks this soldier is a bit awesome!"

"! If it really came from there, I could hold it for ten minutes now..... It's really awesome! ”

Shore.

Zhang Xiaorong looked at the water.

At this point, more than ten minutes must have passed!

But Su Qin was still motionless!

This guy is amazing!

Zhang Xiaorong has to admire!

Suddenly, Zhang Xiaorong couldn't help shouting: "Guitar, come on!" ”

"Qinqin, stop shouting, Gigi can't hear it, he's in the water!" Thundercloud turned to look at him.

"He can't hear it, but he will feel our encouragement! Our seven groups of soldiers should all be standing with him at this moment! Zhang Xiaorong replied, and then shouted: "Guitar, come on!" ”

Thundercloud quickly shouted: "Gigi, come on!" ”

Shi Qingniu was stunned, glanced at a few people, and shouted: "Guitar, come on!" ”

At this time, Su Qin had been sinking into the water for thirteen minutes!

His body was already feeling a kind of uncomfortable pain.

He knew that this was a sign that the body was already starved of oxygen.

Freediving world champion Guillaume Nery and several scientists did an experiment to put the body in a state of hypoxia while holding their breath, and then tested various data on the body!

At one point he held his breath for more than 7 minutes, which was the limit of his breath-holding, and by this time he was on the verge of collapse and almost unconscious!

But in this case, scientists found that there was nothing abnormal in his brain.

And Guillaume has been freediving for more than 20 years, and her brain is no different from that of a normal person.

Therefore, scientists have come to the conclusion that even when people lose consciousness, they are only entering the stage of self-protection, suspending all physical activities to ensure that the brain still has enough oxygen to consume.

At this time, there was no damage to the body.

In the breath-holding stage, if you can not move, it is better for the brain to be blank. Holding your breath is the same as running a long distance, and the most difficult time is when you hold it for a third of the time, when the desire to breathe is very strong, but it is good to stick to it.

In the end, when you can't stand it anymore, you can also spit the air from your lungs into your mouth and then inhale it for a small circulation, so that you can support it for a while.

The human brain accounts for about 25% of the body's oxygen consumption, and emptying the brain as much as possible can indeed reduce oxygen consumption, but we are all human beings, and it is actually impossible to make the brain blank.

And when we don't think about anything, there are just a lot of negative thoughts coming into our minds: "How long can I hold back", "I can't do it anymore", "I can't hold it anymore", and so on.

Fortunately, Su Qin has been practicing meditation, and he has long been used to having a blank brain and not thinking about anything!

So, although he was a little uncomfortable in his body, he didn't immediately think like others, but quickly cut off all thoughts, just as quiet as a mountain!

Click, click, click!

The hands on the stopwatch continue to move quickly!

Gao Xifeng turned his head and looked at his watch.

It's been fifteen minutes!
