Zhang Yifan had no choice but to comfort them: "Actually, there is no need to worry so much! Most microorganisms are harmless to humans and are even beneficial. For example, in the process of fermentation, beneficial microorganisms are at work. In addition, our human body has its own set of defense mechanisms......"

He was talking, whether he believed it or not, everyone present was listening carefully, and no one spoke.

"For example, our nose hair is effective in blocking dust and bad things in the air from entering the human body. If it accumulates too much, the body will also expel it by sneezing......"

Hearing this example, everyone was a little dumbfounded. In their opinion, nose hair is really unsightly, and they wish they could have it, but it still has such an effect?

This is the first time they have heard this statement.

"Also, even if harmful microbes enter our body, our body will have defenses such as white blood cells. You can think of it as an army to protect our human body, fighting against invading microbes. One of the ways in which this manifests itself is a fever......"

This is something they have never heard of again, and after hearing too much, Zhu Di, who was skeptical, couldn't help but question: "According to what you say, this fever is still a good thing for us?" ”

Such a conclusion is a bit subverting their worldview. For them, a fever is just being sick, and how can that still be a good thing?

Hearing his question, many people nodded, feeling that they couldn't accept such a point of view, which was a bit ridiculous!

When Zhang Yifan heard this, he immediately turned his head to look at Zhu Di, and said with a smile: "Some bad things are not resistant to high temperatures, the human body has a fever, that is, there is inflammation, and the white blood cells are fighting." However, our human organs can tolerate a certain range of high temperatures, and if we exceed this tolerance range, fever will also be harmful to the human body. ”

This solution seems to be able to come back to the circle. However, these words just now are still too unbelievable, and for a while, everyone's expressions are different, and it is difficult to believe them all.

Zhang Yifan looked at them, and then added: "Why do we have to cook something to eat, it is not easy to eat bad stomach?" In fact, this is also the truth, use high temperature to destroy those harmful microorganisms! ”

It's common sense, they all know it. However, they don't know what the reason is behind it, anyway, the ancestors passed down this way.

Zhu Di still couldn't accept it all, so he asked: "You just said that you can see these micro-...... with the help of tools Creatures, I don't know what kind of tool it is, can you let us see it too? ”

Although there are examples of dust in the air, it is still not easy for them to believe that there are microorganisms.

In any case, seeing is believing is the most credible.

Zhang Yifan listened, looked at him and replied: "You have to use a microscope, and the light microscope can see some microorganisms." But this thing is not easy to make, and it takes a long time to make it! ”

He knew that Hook's microscope could see cells and the like, which could subvert the perception of ancient people. He also knows how to do Hook Microscope, but at this stage, he has to solve the problem of food and clothing first, improve his living conditions, and live without worries, and it is not too late to do this.

"I believe in you!" Zhu Jingjing listened and said without hesitation.

There is no need to make it, she has already come to a conclusion judging from Zhang Yifan's words and deeds.

When Zhu Di heard this, he couldn't help glaring at her angrily: This girl has been deeply poisoned, and it is estimated that she is hopeless! The only way is to isolate, but she also encouraged the princess to run over, there is really no way to take her!

The crown princess was equally shocked when she heard this, and asked in surprise, "How do you know so many things?" ”

Whether it's true or not, saying so many things, even if it's fake, is powerful enough!

"Hehe, I just know a little bit about it!" When Zhang Yifan heard this, he immediately smiled and responded, and then said, "The topic just now is far away, let's talk about returning to the maternity." ”

Originally, Zhu Di still had questions to ask, but when he heard what he said, he had to hold back and not say anything about it.

On the side of the stable women, whether they believe it or not, they were shocked by Zhang Yifan's remarks, and when they heard him say about returning to the mother, they all subconsciously listened respectfully.

I only heard Zhang Yifan say to them: "When a mother gives birth, her body is in a weak state, and her immunity is poor. That is to say, the army in the human body to protect the body is weak, and at this time, harmful microorganisms are easy to take advantage of the weakness. Therefore, during childbirth, as well as post-childbirth care, that is, during confinement, we must pay attention to disinfection, and the mother should rest well, eat well, recover physical strength, and restore body immunity as soon as possible. ”

"What does Childe mean, many maternal diseases are caused by this harmful microorganism? So how to disinfect? Wen Po Wang listened and asked boldly.

Whether she is a professional stable woman, or is she in charge of delivering babies in the palace, she has seen too many examples. Of course, I had doubts in my heart, so I couldn't help but ask.

Zhang Yifan nodded after hearing this and said: "That's right, objects and the like can be sterilized at high temperature, soaked in boiling water, and if it is inconvenient to use high temperature disinfection, it can be disinfected with high-concentration alcohol, and it is best to disinfect with 75% of alcohol, which can also achieve the purpose." ”

They all understand boiling water, so Wang asked another question: "This alcohol disinfection, the old man can't understand it, and I ask the son to teach me!" ”

After saying that, she was blessed.

Obviously, at this time, she has already corrected her attitude.

When Zhang Yifan heard this, he immediately explained: "There is liquor, distill it, purify the concentration, there are about seventy-five parts of alcohol in one hundred parts, and the disinfection effect is the best!" ”

At this time, liquor was actually already available.

However, in ancient times, the general wine, or the wine that the rich drank was rice wine.

Baijiu tasted bad in ancient times, and it was drunk when you drank a little, which was not liked by people. That is, the poor can't afford to drink rice wine, so they have to drink some liquor to satisfy their hunger.

In addition, high-concentration spirits will not be common until the middle and late Ming Dynasty.

At this time, the kind that heard Zhang Yifan say something very substantial, at least the women, most of them believed it. But the problem is that in every sentence of Zhang Yifan's explanation, there are often other incomprehensions, and I am confused.

Zhang Yifan obviously knows this, if he continues to explain it like this, it is estimated that he will go off topic and don't know where to go, so he decisively did not explain the concepts of distillation, concentration, etc., and continued: "There is another point, after the baby is born, you must pay attention to heat preservation. Wealthy families should have no problem, ordinary people's families, it is best to have an incubator, especially for babies under a month, it is necessary to pay attention to heat preservation. This is ...... for humans and animals alike."
