The impacts of positive psychological states on physical health: A review and theoretical framework

While much research has focused on the impacts of negative psychological states, such as stress, on physical health, relatively little research has examined the effects of positive psychological states. We suggest this imbalance is attributable to inadequate theoretical and methodological development regarding the impacts of positive psychological states on health. This paper presents a framework by which positive psychological states may influence physical health. Following this, we review evidence pertaining to this framework. We conclude by discussing methodological issues associated with this relatively new area of inquiry.
