What is the best way to explain mental
WHO definition of mental health
The World Organization defines mental health as “a state well-being in which an individual realizes his or her own abilitiesowns can cope with the normal stresses of life, can work productively and is able to make a community.” World Health Organization) This is not a narrow clinical label — it is a broad, positive concept that applies to everyone, not just people with a diagnosis.
How do you define mental ill health?
A mental disorder, according to the DSM-5, is “a syndrome characterized by clinically significant disturbance in nation, of behavior.” (NCBI/NIH) The WHO these conditions are existing usually associated with distress impairment in important areas of functioning.” (World Health Organization) The key point: mental health and mental illness are not opposites — someone with a diagnosis can still have good mental health, and someone without a diagnosis can struggle.
“Mental health is a state of well-main one of ability that individual realize his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a community to his or her community.”
— World Health Organization
The implication: the WHO definition deliberately avoids tying mental health solely to the absence of illness. It frames it as a universal continuum — something everyone can work on, regardless of diagnostic status.
