Positive Psychology and Physical Health: Research and Applications.

Positive psychology is the scientific study of a healthy and flourishing life. The goal of positive psychology is to complement and extend the traditional problem-focused psychology that has proliferated in recent decades. Positive psychology is concerned with positive psychological states (eg, happiness), positive psychological traits (eg, talents, interests, strengths of character), positive relationships, and positive institutions. We describe evidences of how topics of positive psychology apply to physical health. Research has shown that psychological health assets (eg, positive emotions, life satisfaction, optimism, life purpose, social support) are prospectively associated with good health measured in a variety of ways. Not yet known is whether positive psychology interventions improve physical health. Future directions for the application of positive psychology to health are discussed. We conclude that the application of positive psychology to health is promising, although much work remains to be done.
