In summer, or when the weather is hot, I find myself stuttering. What happened?

Hehe, stuttering, this problem is mainly psychological tension, especially for introverts, who are prone to stutter when expressing things and talking to people, and cannot speak clearly. The more nervous I am, the less I can say it. First of all, you should get rid of your introversion, don't be shy, and dare to stand out in everything. Then you can recite novels, poems and other rhythmic things by yourself at home. You can read slowly first, and then speed up your speech. Stuttering is not a big problem, and it has nothing to do with the weather, but your psychological role accounts for most of it. Try to overcome it yourself.
