Majority of psychologists and social workers have agreed that “complete maturity” terms may be used as mental health. Physical, sexual, and intellectual maturity is achieved generally around the chronological age of 20 years. It is also well known that after this age, much changes are not observed in these areas as far as growth is concerned. But attaining maturity in physical, sexual and intellectual areas only is not the complete maturity. Besides these areas, the inclusion of emotional, social and role understanding are of utmost importance, which together could be considered complete or comprehensive maturity or mental health.
According to WHO, there is no single 'official' definition of mental health. Mental health refers to a person's psychological, emotional, and social well-being; it influences what they feel and how they think, and behave. The state of cognitive and behavioural well-being is referred to as mental health. The term 'mental health' is also used to refer to the absence of mental disease.
Mental health means keeping our minds healthy. Mankind generally is more focused on keeping their physical body healthy. People tend to ignore the state of their minds. Human superiority over other animals lies in his superior mind. Man has been able to control life due to his highly developed brain. So, it becomes very important for a man to keep both his body and mind fit and healthy. Both physical and mental health are equally important for better performance and results.
