Health Impact

A health impact can be positive or negative. A positive health impact is an effect which contributes to good health or to improving health. For example, having a sense of control over one’s life and having choices is known to have a beneficial effect on mental health and well being, making people feel “healthier” (Wilkinson, 1996).

A negative health impact has the opposite effect, causing or contributing to ill health. For example, working in unhygienic or unsafe conditions or spending a lot of time in an area with poor air quality is likely to have an adverse effect on physical health status.
