Xiaobei turned one year old and had seven teeth. During the physical examination, the doctor told me: \”It\’s time to brush the baby\’s teeth.\” I agreed, but I didn\’t take it to heart, and I often forgot to brush Xiaobei\’s teeth. This morning, I suddenly remembered this, so I took out the soft baby toothbrush I bought a long time ago and put it into Xiaobei\’s mouth. Xiaobei only thought it was fun, but he didn\’t cooperate. He grabbed the toothbrush, bit it, and wanted to run away. I had to chase him. Grandma looked at it and didn\’t understand: \”You have to brush his teeth for such a big baby. Don\’t you think it\’s funny?\” \”What\’s so funny about this? The doctor said I need to brush his teeth.\” I said impatiently. After saying that, I immediately thought, yes, why should I brush the teeth of such a big baby? He usually only eats milk and porridge, and he hasn\’t grown molars yet, so there won\’t be any food left on his teeth? In my understanding, only food residue on the teeth can cause tooth decay. But if this is the case, why does the doctor recommend brushing the baby\’s teeth? I immediately went online to find the answer, and then I realized that the real role of brushing my teeth is not only to remove residual food, but also to remove plaque formed by saliva and bacteria on the tooth surface. The following is relevant information from the Internet query: Babies begin to grow teeth around 6 months after birth, and generally all 20 deciduous teeth have appeared by about 2 and a half years old. From the moment the first deciduous tooth erupts, parents should start paying attention to protecting their children\’s teeth and cultivating good oral hygiene habits in their children. Because oral hygiene is closely related to the occurrence of various oral diseases, especially gingivitis, periodontal disease and caries, one of the most effective and simplest ways to prevent the occurrence of these diseases is to brush your teeth. So what role does brushing your teeth play? Glycoproteins in saliva can work with bacteria in the mouth to form plaque on the tooth surface. At the same time, after a child eats, there will always be food residue left around the teeth, such as in the gaps between the teeth, in the pits and fissures on the surface of the back teeth, and at the edges of the gums. Medically, these food residues and dental plaque are composed of substances called For soft dirt. On the one hand, the bacteria in the food decompose and ferment the sugars in the food to produce acid, which destroys the hard tissues of the teeth and leads to dental caries; on the other hand, the toxins produced by the bacteria can also destroy the gums and surrounding tissues, causing gingivitis and periodontal disease. In addition, if the soft tartar is not removed in time, the minerals in the saliva will gradually deposit on it and calcify into hard tartar. These tartar can further stimulate gingival inflammation. Because tartar stays at the gum edge or in the gingival sulcus for a long time, more and more tartar accumulates. , constantly irritating the surrounding gum tissue and aggravating the damage to the gum tissue, and at the same time compressing the gums, causing the gums to recede and expose the tooth roots, making the teeth look very long. Therefore, it is very important to remove soft tartar from teeth and control the formation of dental plaque. General mouthwash can remove food debris and some soft plaque, and can temporarily reduce the number of bacteria in the oral cavity, but it cannot remove dental plaque. Brushing teeth can not only remove dental plaque, soft plaque and food debris through mechanical action. , it can also massage the gums, promote blood circulation in the gums, and improve the health of the gums. After knowing why, I will pay more attention to this issue in the future, take it to heart, and be more able to persist in doing this. This incident reminds me to keep a focus on lifeBe sensitive and curious, and be wary of your own intuitive thinking. Even when faced with common sense in life or expert opinions, you should always ask why. Otherwise, if you only have a partial understanding, you will be easily shaken in doing things and unable to stick to the end. I remembered that when I first started working out two years ago, it was the same. I didn’t understand anything, so I looked for information everywhere. At first, I followed the video movements and followed them, but I had no idea what the use of doing these movements was, so I kept doing them. I started to wonder, \”Whether it\’s useful or not?\” As a result, I fished for three days and dried the nets for two days, and I couldn\’t persist at all. It was not until later that I started browsing Zhihu and reading a lot of professional articles from fitness gurus that I got started. I understood the principles of muscle growth and the parts that each fitness movement exercises, and I formulated an exercise plan. After understanding the relevant knowledge, I will consciously feel the feeling of muscle exertion every time I do a movement. At this time, I know exactly what I am doing and what movements I should do if I want to exercise which part of the body. This feeling of self-control made me more determined to complete the exercises, so the effect was extremely significant. I developed the vest line in just three months, and it also allowed me to persist in fitness for more than a year like never before, until I became pregnant with my second child. . Not only common sense in life, but also we can easily fall into intuitive thinking when it comes to unfamiliar things. For example, I\’ve been feeling upset lately and can\’t calm down, so I started practicing meditation, which is commonly known as sitting meditation. When they hear about zazen, many friends may say, isn’t this what monks in the mountains and forests do? Are you going to practice too? Don\’t tell me this mysterious stuff, I don\’t want to become a monk. This is our common intuitive thinking. I used to think so too. In fact, not only monks, but also many scientists, thinkers, and scholars are keen on meditation. Meditation is not a metaphysics. More and more scientific studies have found that meditation has profound positive effects on thinking, emotions and the brain. The Harvard Happiness Course: Exercise and Meditation has a very detailed content on this: \”Studying the ratio of their left and right prefrontal cortex, after only eight weeks, those who meditated showed significant changes. This is an amazing result. Remember , before 1998, scientists were convinced that the brain was not plastic and would not change after the age of three. Suddenly, after just eight weeks of practice, these meditators, those who meditated regularly for 45 minutes a day, changed their brains This function makes them more susceptible to positive emotions and more resistant to pain. Herbert Benson of Harvard Medical School found that meditation for 15 to 20 minutes every day can greatly improve health after a period of time. Emotional health and physical health improved. Because Jon Kabat-Zinn did another study where he injected two groups of people with cold bacteria and what he wanted to test was how the antibodies in their bodies would react. He found that people who meditated have a much stronger immune response than those who don\’t meditate. Those who are waiting to meditate, just meditate for eight weeks, 45 minutes a day. You know when we are calmer, our resistance to disease increases, and we When you are anxious, you are more likely to get sick. So meditation can increaseStrengthen the psychological immune system, enhance psychological resistance, and at the same time improve the physical immune system. \”There are also brain science studies that show that meditation practice can indeed change the brain structure, making people more focused and smarter! You see, the ancient masters often practiced in seclusion for half a year. There is really a scientific reason! Some mothers, in In the process of raising children, when she encounters a problem, she does not ask why first, but immediately seeks the answer from others. When others want to explain this phenomenon to her, she says: \”I don\’t understand what you said. I don’t have time to study these, so just tell me how to do it. \”If your mind is simple enough and you absolutely trust this person, you may be able to solve the problem if you stick to it. Unfortunately, most people are asking others for help while doubting what others say. At this time , if you don’t understand why, it will be difficult to stick to things or handle things flexibly. In this case, the same problem will appear again, and you will fall into a vicious cycle of being tired of dealing with problems. Think about whether you Are you getting angry over and over again because of your child\’s dilly-dallying, are you anxious over and over again because of your child\’s going to bed late, are you trying to lose weight but failing time and time again? Only by understanding the psychological reasons behind your child\’s dilly-dallying and understanding yourself The source of anxiety. Only by understanding the principles of weight loss can you have a firm belief and continue to work hard to change, so that things can develop in a good direction. Be wary of your own intuitive thinking and ask more why. This is what I learned in the process of raising children. A lesson. Now, in my daily life, when I do things, whether it is childcare, work or study, I often ask myself a few more questions: – What am I doing now? – Why am I doing this? What do I think? ? – Is there any other choice? – What else can I do? – How to do it better? Let us practice together and move from intuitive thinking to rational thinking.
