First of all, the meaning of life refers to a person's subjective evaluation of the meaning or value of himself, others and society. A person who has positive significance to life usually feels that he has the value of existence, can actively cope with the difficulties and challenges in life and maintain mental health. On the contrary, a person with a negative meaning in life may feel helpless, lonely and desperate, which may lead to mental health problems.
Secondly, mental health refers to a person's mental health, including emotions, cognition, behavior and interpersonal relationships. A mentally healthy person can usually cope with the pressures and challenges in life better and gain positive meaning in life more easily. On the contrary, people with poor mental health may have a negative impact on the meaning of life.
Therefore, the meaning of life and mental health are mutually influenced and interacted. The meaning of a person's life will affect his mental health, and mental health will also affect his cognition and evaluation of the meaning of life. In order to maintain physical and mental health, we need to pay attention to these two aspects at the same time, actively explore and find the meaning of life, and maintain good mental health.
