There may be many people who have farted in public places. In order to avoid this embarrassment, many people will choose to try to be as lighter as possible, at least not saying ...

There will be some people, in order to avoid embarrassment, forcibly put the fart back ...

In fact, farting is a normal physiological phenomenon. Under normal circumstances, people will fart 10-15 times a day, and discharge about 500 ml of gas.

Among them, there are about 1-2 farts, and silent farts account for more than 10.

It's really elegant, but does it have no effect on our body? Today, let's temporarily put down the prejudice of farts to make a taste of popular science for everyone.

How did farts produce?

Fart, also known as qi, refers to the exhaust gas from humans or animals from anus.

There are more than 1,000 kinds of intestinal microorganisms, from near -end intestine to remote intestine, the number of bacteria gradually increases.

The food we eat is mixed with saliva, gastric juice, and pancreatic liquid bile, and slowly reaches the intestine. The intestinal microorganisms continue to decompose the food, produce gas during the decomposition, and discharge through the anus. This is fart.

Another source is the air swallowed when eating, so it makes sense to chew slowly and not to speak.

What are the composition of fart?

Fart is mainly composed of 59%nitrogen, 21%hydrogen, 9%carbon dioxide, 7%methane, and 4%oxygen, but these gases are tasteless.

There are less than 1%consisting of trace of other chemicals -such as ammonia and hydrogen sulfide.

The composition of fart is indeed varying from person to person. After all, everyone's intestinal biological characteristics are different.

But the smell of fart is produced by these less than 1% ammonia and hydrogen sulfide.

Hydrogen sulfide will release the smell of stinky eggs, and the odor like rotten cabbage is likely to be produced by methane sulfitanol, and those that smell a bit of fragrant farts are the credit of diracle sulfe ether.

What can hydrogen sulfide affect the human body?

Recent studies have pointed out that the fart may contain a compound that is beneficial to people.

This is because the human body contains a special enzyme called cypressulfonal etch enzyme, which has many benefits to the human body.

1. Regulate blood pressure. The research team at Leikheid University in Canada found that hydrogen sulfide in the blood can reduce the blood pressure of the mice.

2. Regulate inflammation. Studies have found that taking drugs with enteritis can release low -dose hydrogen sulfide, which can reduce its inflammatory response.

3. Stop bleeding. Intravenous injection of hydrogen sulfide can temporarily reduce the need for oxygen due to blood loss, thereby increasing the chance of waiting for blood transfusion and treatment.

4. Extend life. Hydrogen sulfide can increase the life of the nematode by 70%. This means that living in an air environment containing an appropriate amount of hydrogen sulfide may prolong life.

Although there are many benefits of hydrogen sulfide, there is a harm that cannot be ignored -neurotoxicity.

The main target of hydrogen sulfide is the central nervous system and respiratory system. When the concentration is low, the eyes are tingling, tears, and vomiting, and sometimes pneumonia and pulmonary edema; when the hydrogenation of hydrogen sulfurization, it will damage the brain.

Only less than 1%of hydrogen sulfide can still not be tied with fart.

Where did the fart go?

If you often fart, it will cause the gas to slowly accumulate in our intestine, and abdominal distension and abdominal pain will also cause abdominal distension and abdominal pain.

However, the gas cannot disappear out of thin air, and the fart that cannot be discharged will flow around the body. Some of them enter the whole body cycle as the blood entering the body, and may enter the lungs out of the body, and some will be absorbed in the body.

Fart contains some toxic and harmful substances. If we often fart, these toxic and harmful substances are likely to slowly affect our intestinal health.

So you can let it go.

How to relieve the embarrassment of fart?

Drink plenty of water and eat more high -fiber foods, such as vegetables, fruits, grains, etc.

Perform proper physical exercise often.

Edible dairy products and sugars should be appropriate, especially those with lactose intolerance should reduce lactose intake.

Careful use will cause abdominal distension drugs. Do not take too much.

In short,

Fart is the physiological phenomenon of our body,

Just find a unpleasant place to release it.
