I don't have a system but I have a hammer

Then there's the skin tone...

Although the flexibility and resistance of the skin are far superior to the human body, I really don't like the skin color, because it is all cement gray from the beginning to the end...

That's right, the skin color is the same as that of the Raul people, even a little darker than their gray-white skin. It is no different from a fool who jumped into a cement pool. He will definitely be ridiculed when he returns to the earth...

well?wrong…

This is not completely useless, at least it looks more like an alien on the outside, one can use this to get rid of Xiaohong's entanglement, and two can grasp more initiative when negotiating with others, which makes me feel more comfortable Already...

The rest is just bodily functions...

I first found a pool and simply tested my vital capacity, and the data I got was quite surprising...

Static vital capacity...23 minutes and seven seconds!

Dynamic vital capacity...45 minutes and [-] seconds!

The above two data are tested in a very casual state, that is to say, the body and brain have hardly made much preparation for this...

This is what really surprised me!

As we all know, there are two types of breath-holding, one is oxygen-absorbing breath-holding, and the other is oxygen-exhausting breath-holding...

For the former, no matter how strong a person's lung capacity is, it is impossible to break through the limit of 10 minutes, even for professional athletes...

Because oxygen inhalation and breath-holding are mainly used for underwater activities, only by filling the lungs with oxygen can the body cells be continuously supplied to ensure underwater activities...

In other words, you just don't take in oxygen, but your body is still consuming oxygen, and you have to expel carbon dioxide, otherwise carbon dioxide stays in the body for a long time, and it will cause great damage...

This process takes about 2 to 3 minutes. People with high lung capacity store more oxygen, so the time can be increased to 5 to 8 minutes, but 10 minutes is always a barrier, because the concentration exceeds 15%. Carbon dioxide, in the human body for more than 10 minutes, will directly cause death, not to mention the concentration of more than [-]%?

This is why many people can't hold back after two or three minutes underwater, because the brain will force you to expel carbon dioxide from your body...

At this time, someone asked, then if I discharge the carbon dioxide, can I hold my breath for a long time again?

Wrong, because the process of expelling carbon dioxide is also a process of exercise, so it is equivalent to consuming the little oxygen left in the cells. Because of this, the brain will urgently need more oxygen after the body emits carbon dioxide , to supply yourself and the cells everywhere, to ensure that you will not lose consciousness due to lack of oxygen...

So why, there is no way to hold your breath for more than 10 minutes, because carbon dioxide is a fast man, and its residence time in our body cannot exceed 10 minutes...

So what is deoxygenation and holding your breath?

That's right, as the name suggests, you expel the air from your lungs before you hold your breath...

It's incredible, doesn't it?

How can you hold your breath after you have exhausted the air in your lungs?

However, the fact is that the time of holding breath with oxygen exhaust is far longer than that of breath with oxygen, including the Guinness World Record holder who holds his breath underwater. of…

The principle is very simple. In fact, when a person empties all the oxygen in the lungs, the body will immediately fall into a state of hypoxia, but although it is hypoxia, there is still a small amount of oxygen in the body, such as blood oxygen. …

That's right, the blood oxygen saturation of a normal person is above 90.00%. When you exhaust the oxygen in the lungs, the blood oxygen saturation remains unchanged, and the functions of all parts of the body are still in a state of normal operation. Only When the blood oxygen is lower than 90.00%, people will feel chest tightness and shortness of breath...

When it is lower than 90.00%, various problems begin to appear in the body function, and there will be obvious symptoms of hypoxia, such as dyspnea, dizziness, dark eyes, lethargy, and confusion, but it has not yet reached the point of threatening life...

But when it is lower than 80.00% five, it is already a typical state of respiratory failure. Afterwards, respiratory arrest and cardiogenic shock will beckon to you beside the pillow...

But before that, in order to prevent you from falling into a coma or losing consciousness, the brain will urgently mobilize the little remaining oxygen, supply all of it to important parts of the body, such as the heart and brain, and reduce the activity level of other parts. To the lowest, to save your poor and weak life...

In this state, the beating frequency of your heart and the activity level of various parts of your body will drop to the lowest level in history. It can be said that apart from thinking, even if you just move your fingers casually, you may go into a coma directly...

It can even be interpreted as a person who is about to enter a semi-comatose state of shock, and all we have to do is...

Take the initiative to get this status!

That's right!

In fact, in the diving world, this state is called…

Zen!

Of course, it does not refer to the state of going into shock, but refers to the state of the body with extremely low oxygen consumption...

The lower the oxygen consumption, the lower the carbon dioxide content produced, and the longer the breath holding time will naturally be...

You must know that the brain accounts for only [-]% of the human body, while the heart accounts for [-]% of the body, which is equivalent to about [-]% of the human body...

So when you supply all the oxygen in your body to the brain and heart, then you will reduce the oxygen consumption by 90.00%, and also reduce the carbon dioxide production by 90.00%, and you will get more breath-holding time in disguise. , this is the so-called Zen state...

At this time, if there is excess oxygen in your lungs, the brain will think that your body is still healthy, so it will send the excess oxygen to other parts, so that the production of carbon dioxide returns to its original level , will eventually cause you to be forced out of the Zen state...

This is why you must empty your lungs of oxygen if you want to break through the 10-minute breath-holding limit...

As for how to enter the Zen state, the way is to hold your breath for a minute to two minutes in small amounts several times. Each time you inhale less oxygen than the last time, until you can hold your breath for 2 seconds without inhaling oxygen. Then even if you have entered the beginner stage of Zen...

Of course, if you want to hold your breath for more than 10 minutes, you have to go through months or even years of professional training before you can do it...

So now back to me...

I didn't go through any training at all, and I didn't even exhaust the oxygen in my lungs. I just buried my head in the water casually, and broke the world record...

One can imagine how strong my body is!

Normal people have two lungs...

And me?

Ten lungs!
