Mental health and unhealthy are two opposite sides.

No, mental health is a concept of dynamic development, which shows that mental health is a kind of reaction to the external environment in our hearts and is constantly changing, so it is a concept of dynamic development.

Mental health is different from physical health and has more objective standards. The above contents are interrelated. A person's mental health is not necessarily manifested in all aspects, but often in one or two serious imbalances. If a person's words and deeds deviate from his age, it is often a sign of mental health.

In addition, children and adolescents are in the growth stage. Students of different ages have different requirements at different levels. A child's mental health depends mainly on whether his mental state and behavior are consistent with most of his peers, that is, whether his words and deeds are consistent with his age, and he cannot simply "sit in the right place."

Children in the lower grades of primary school can't understand themselves correctly, lack consciousness of their own behavior, lack independence, and rely on teachers and parents, which is a manifestation of low level of self-awareness. In senior three, with the improvement of self-awareness, independence is gradually enhanced, and the ability of self-cognition, self-evaluation and self-adjustment is developed. At this time, children will consciously develop their self-cognitive ability and improve their self-cognitive level.

In daily study and life, children often encounter all kinds of troubles and puzzles due to subjective and objective reasons, and often suffer psychological setbacks, resulting in all kinds of psychological obstacles, such as cognitive obstacles, interpersonal obstacles, emotional obstacles, weariness of learning, teacher-student unity and so on.

In the work of mental health education, a large number of formative education is the main thing, and transformation education is the remedial measure when necessary.
