1. Teachers' mental health directly affects students' mental health. Students spend more than ten hours in effective contact with teachers at school every day. In school, teachers are of course dominant and dominant. Teachers' smiles have a profound and lasting influence on students. Teachers with mental health can design a good psychological environment to promote the healthy development of students' body and mind. One of the reasons why students have psychological barriers such as fear, lying and disobedience is related to the mental health of teachers. The research shows that a class teacher with a high level of mental health has a high level of mental health of his students, and vice versa. 2. Teachers' psychological state will affect teachers' attitude and evaluation of students. There is a famous "Rosenthal" effect in psychology, which is about the influence of teachers' expectations on students. The experimenter randomly selected some students from several classes. Some of these students study well, others study poorly, and most of them are average. Then tell their teachers that these students have special potential and will make great achievements in the future. A year later, the experimenter found that these students really became top students. No matter whether the original foundation is good or bad, every student has made remarkable progress than his original level. The experimenter told the teacher the truth and results of the experiment, and the teachers were quite surprised. In fact, the knowledge level of teachers has not changed much, but the attitude towards students has changed. 3. Teachers' mental health directly affects students' knowledge learning. It is difficult for a teacher in a bad mood to create a pleasant and relaxed classroom teaching environment. They often show irritability, irritability, easy conflict, moodiness and emotional instability. Teachers' emotions will affect students. If students are often in a state of tension and anxiety, their learning efficiency is not high and their learning effect is poor, which will lead to psychological problems and even diseases in the long run. On the contrary, teachers with healthy mentality, positive attitude towards life and active teaching will try their best to continuously improve teaching methods and teach students in accordance with their aptitude, and students will also take the initiative to learn and think. Teachers' positive emotions and healthy psychology will induce students' positive emotions, promote the formation of students' healthy psychology, and have a direct impact on establishing a good teacher-student relationship, creating a relaxed and happy classroom atmosphere, and students' acceptance and understanding of knowledge. 4. Teachers' mental health directly affects the relationship between teachers and students. If teachers' psychology is unhealthy, it will be difficult to correctly understand students' psychology and behavior, and unreasonable attitudes and methods will be adopted to treat problems, which will lead to contradictions and conflicts between teachers and students. Now some teachers often complain that students are becoming more and more difficult to teach, and teachers make every effort to educate students, but students either go their own way or "do what they say." Eriksson, a famous psychologist, once pointed out that bad teacher-student relationship will lead to students' mental illness, while good teacher-student relationship can cure diseases. If you meet a good teacher, the unhealthy psychology of students caused by their family can be changed. The opposition between teachers and students is not conducive to students' study. Whether there is an antagonistic relationship between teachers and students and whether the antagonistic relationship can be properly solved ultimately depends on the psychological state of teachers. 5. Teachers' mental health directly affects students' personality development. In the process of students' growth, teachers are important figures, references and role models. Especially for primary and middle school students, because of their limited cognitive level, students have insufficient ability to distinguish right from wrong, and have not yet formed an independent self, so it is easy to imitate others, especially teachers and parents. Whether the teacher is in a good mood or not, whether he likes working or not, will affect the students. If teachers punish and retaliate against students, students will form the habit of hostility and confrontation and form psychological barriers. Teachers' unfair treatment and abuse of power will affect students' views on the whole society.
6. Teachers' mental health directly affects the formation of students' sound personality. Teachers with mental health can treat students with a happy, serene and calm attitude; Influence students with enthusiasm, openness and sincere personality charm; Solve the contradiction between teachers and students with cordial and sincere language; It makes students feel cordial, warm and intangible at all times, and plays an important role in cultivating students' excellent psychological quality and sound personality.
7. Teachers' mental health directly affects the formation of students' good interpersonal relationships. Teachers with disharmonious interpersonal relationships can easily lead to psychological diseases such as loneliness, depression, anxiety, tension between teachers and students, and form negative attitudes such as disgust, hatred and discrimination against students. Teachers with good interpersonal relationships trust, appreciate, treat each other sincerely and care for each other when they are away from students. Such a teacher-student relationship not only helps teachers to establish their own prestige, but also guides students to grow up healthily, especially in promoting students' unity and cooperation. To sum up, teachers' mental health is not only related to teachers themselves, but also to the healthy development of students' body and mind, and to the success or failure of education in China.
