Do you want to practice breathing after watching Ghost Blade? Science tells you how to repair eggs!

In the third episode of Ghost Blade Animation, master Tan Erlang first mentioned "breathing attentively": "Take a deep breath and let oxygen enter every cell of your body. In this way, your body's natural healing power will be improved, your spirit will be calmer and your thinking will be more flexible. 」

Guys, aren't you happy? You can't breathe! (Angry) In the same episode of IMDb, Shinji told Tanjiro the secret of "concentrating on breathing": "In short, it is to enlarge the lungs and let more air enter the blood. 」

From these two sentences, we can know that "full concentration breathing" means "increasing the oxygen content in the blood by inhaling more air than usual, thus strengthening the body function. 」

Under the guidance of Shinji, Tanjiro finally learned to concentrate on breathing. IMDb sounds like such a thing, but is it reasonable? Let's see if breathing is scientific!

Inhaling more air can increase blood oxygen? Both "red blood cells" and "plasma" in blood carry oxygen, of which the oxygen carried by red blood cells accounts for the majority, and other oxygen is dissolved into plasma by physical means.

The number of red blood cells in human body is fixed, and the number of saturated red blood cells carrying oxygen in healthy people's arteries accounts for 98% of all red blood cells, even 100%, so inhaling more air will not increase the oxygen carrying capacity of red blood cells. As for the oxygen content in plasma, it is only related to atmospheric pressure and oxygen concentration. On the flat ground, unless pure oxygen is inhaled, the oxygen in the plasma will increase.

Concentrate on rapid breathing, put on an oxygen mask and inhale pure oxygen. Although inhaling more air will not increase the oxygen content in the blood, if you take a shot of "stimulant", not only the blood oxygen concentration will increase, but also the body function will be improved!

Stimulants are prohibited drugs in sports, and its official name is erythropoietin (EPO).

As the name implies, EPO can promote the production of red blood cells, and the increase in the number of red blood cells can make the blood carry more oxygen. However, the increase of blood oxygen concentration will effectively improve the performance of endurance competitions (such as marathon), so EPO is listed as a banned drug.

Before EPO was invented, in order to increase the number of red blood cells, players would draw blood one week before the competition, rest for one week to restore the number of red blood cells to normal, and then return the saved blood to the body before the competition. At this time, the number of red blood cells in the player's body is more than usual, and he can carry more oxygen. It is also illegal to do so. )

Blood transfusion improves body function, does it make you feel that the blood of the ghost king becomes a strong ghost? However, blood transfusion and EPO application are very dangerous. Excessive red blood cells can thicken blood, easily form blood clots and block blood vessels, leading to tissue necrosis, stroke or heart disease.

Therefore, it is not unreasonable to mention in the animation that if you input too much blood from the ghost king, your body will not be able to bear death.

Can you stand my blood? In addition to safety, IMDb suggests that injecting erythropoietin can increase blood oxygen concentration more effectively than practicing "concentrate on breathing".

Don't concentrate on breathing! If you still want to practice "full concentration breathing", don't do it all at once, you may hyperventilate.

Hyperventilation is a series of physiological reactions that lead to the decrease of carbon dioxide concentration in the body because a large amount of air enters and exits the lungs in a short time, so that the rate of carbon dioxide excretion is greater than that made by the body.

Hyperventilation has two ways of breathing. One is typical shortness of breath, and patients are usually seen breathing in paper bags. This is to let patients suck back the carbon dioxide they spit out and increase the concentration of carbon dioxide in the body.

Typical hyperventilation. Another way for GIPHY to breathe is to inhale excessive air and then spit it out, just like "full concentration breathing".

Wait, what about hyperventilation? In a short time, the human body will accelerate metabolism to produce more carbon dioxide due to insufficient carbon dioxide concentration. However, in a long time, due to the continuous lack of carbon dioxide concentration in the body, the concentration of carbonic acid in the blood will decrease and the pH value will increase, and then it will fall into respiratory alkalosis, leading to dizziness, dizziness and chest tightness? Wait for symptoms.

In a word, keeping your breath absorbed for a short time will promote metabolism and slightly improve your body function, but it will be poisoned for a long time. A person who is in a state of poisoning is like Tan Erlang who keeps breathing completely and puts down his string five. He is out of breath and can't move all over.

Soon, the tidal wave of Tan Zhilang will fall into respiratory alkalosis. Is it feasible for IMDb to "concentrate on the whole work and always concentrate on it"? In the 24th episode of animation, Tan Erlang began to practice holding her breath with rapt attention at all times, that is, "concentration is constant".

However, keeping fully concentrated breathing (hyperventilation) will not cause alkalosis? The devil hides in the details! Hyperventilation for a long time can cause alkalosis because the body tries its best to metabolize and produce carbon dioxide, which can not maintain the concentration of carbon dioxide in the blood.

So that your metabolism can keep up with your breathing and you won't be poisoned?

Yi Shan demonstrated rowing to build back muscles. Although theoretically speaking, if IMDb can keep up with breathing, the possibility of poisoning will be less, but it still has its limitations. For example, we can see that when the protagonists practice "concentration and concentration", they do a lot of weight training in addition to the breathing training of blowing gourd, and weight training is the best way to improve the basal metabolic rate.

Compared with methods or skills, "concentration and constancy" is more like an indicator of physical strength. When the basal metabolic rate of the body reaches a certain level, it will naturally inhale air continuously.

In addition to these, the author hides many training methods that exist in reality in the story. For example, Tan Erlang trains at high altitude and lacks oxygen. In reality, there is a "plateau training method". Or blowing gourd, the wind musicians will also carry out similar training to improve their vital capacity. (But they shouldn't be able to blow gourd, just ...)

While enjoying a good work, don't miss the author's ingenuity.
