Mental health is a state of mental well-being that enables people to cope with the stresses of life, realize their abilities, learn well and work well, and contribute to their community. It has intrinsic and instrumental value and is integral to our well-being.

At any one time, a diverse set of individual, family, community and structural factors may combine to protect or undermine mental health. Although most people are resilient, people who are exposed to adverse circumstances – including poverty, violence, disability and inequality – are at higher risk of developing a mental health condition.Many mental health conditions can be effectively treated at relatively low cost, yet health systems remain significantly under-resourced and treatment gaps are wide all over the world. Mental health care is often poor in quality when delivered. People with mental health conditions often also experience stigma, discrimination and human rights violations.
