Positive Emotion and Health: Going Beyond the Negative.

This study examined the relationships between positive emotions and health. Two positive emotions were considered, hope and curiosity, in conjunction with 3 physician-diagnosed disease outcomes: hypertension, diabetes mellitus, and respiratory tract infections. Medical data were abstracted over a 2-year period from 1,041 patient records from a multispecialty medical practice, and emotions were assessed through a mailed questionnaire. Across 3 disease outcomes, higher levels of hope were associated with a decreased likelihood of having or developing a disease. Higher levels of curiosity were also associated with decreased likelihood of hypertension and diabetes mellitus. Results suggest that positive emotion may play a protective role in the development of disease.
