Why do some people keep the faucet running while brushing their teeth?

The first thing a person does when they get up every morning is to open their eyes, get rid of the first thing of the day after getting out of bed, and then brush their teeth, wash their face, and dress up. Everyone has a different way of brushing their teeth, washing their face, and dressing up. Take brushing as an example. The toothbrush you use for brushing your teeth has a personal preference. The same goes for toothpaste. These don't matter. What's more important is that some people will keep brushing their teeth on. Faucet, and some people can do without turning on the faucet. I think most people who don't turn on the faucet are like this. Maybe what people don't understand is why they waste water by leaving the faucet on all the time? As an unprofessional person, I would like to tell you my understanding. When people brush their teeth, do they rub toothpaste back and forth on their teeth to produce foam? As for the composition of the foam, I don’t know. Let’s take a look at Baidu and the foam will be spit out. On the washbasin, of course I had nothing wrong with me and would not keep the faucet on. However, some people will vomit if they don’t turn on the faucet to rinse. However, there is no vomit, and they just act like vomiting, because it looks like they are vomiting. They will feel sick when they see this bubble. There is only one reason for nausea, that is, the dirty things washed out of their mouths gather together and become foam, so they will vomit when they see it, and they have to open the faucet so that they cannot see it. This is the main reason. reason. As for me, this has happened to me before. Even though I didn't turn on the faucet, I still occasionally vomited like nausea. As for why I am like this, I don't know. I remember when I was in high school, one day I had an English teacher’s class. The English teacher was a woman. I don’t know why this topic suddenly came up. It might have come up in the English text, and then the classmates started talking about me. At the end of the discussion, my English teacher said that I must turn on the faucet every time I brush my teeth in the morning. Although I know it is a waste of water, if I don’t rinse away the foam I spit out, I will feel sick and want to vomit, so I must not Don't turn on the faucet. So I believe everyone should understand why those people keep the tap on while brushing their teeth. It’s not that they waste water on purpose, but it varies from person to person. Everyone’s mysophobia is different. When you switch to him, you don’t turn on the tap when brushing your teeth. , vomiting occurs all the time, and you will do the same. Many people think that this may be a symptom of chronic pharyngitis. In fact, it is not, and it is just caused by some other reasons. For example, if you squeeze out too much toothpaste, the foam will run into your throat when your teeth are rubbed back and forth, irritating your throat and possibly causing you to feel nauseated and retching. These are all asymptomatic phenomena.
