Q.What is wellness? What is importance of wellness?

Wellness is NOT the same as health. Health, per WHO, is "a state of physical, mental and social well-being, not merely the absence of disease," and focuses on an individual's illness status. Wellness goes further: it is the FULL integration of physical, mental and spiritual well-being, and it is about living a life of personal responsibility — taking proactive steps to control risk factors (actions or conditions that raise the chance of illness/injury, e.g. smoking raising lung-cancer risk, alcohol raising liver-damage risk) rather than waiting to react to illness after it happens.

The WHO Health Promotion Glossary (2006) defines wellness as "the optimal state of health of individuals and groups," with two focal concerns: realising a person's fullest potential (physically, psychologically, socially, spiritually, economically) and fulfilling one's role expectations in the family, community, workplace and other settings. Other scholars (Corbin, Welk et al.) describe it as the integration of many components — physical, emotional/mental, intellectual, social, spiritual — that expand a person's potential to live and work effectively and contribute to society; the National Wellness Institute calls it "an active process through which people become aware of, and make choices toward, a more successful existence." …
