A new study shows that optimistic women live longer and healthier.

Optimistic women live longer and healthier lives than their pessimistic peers, a new study suggests. Specifically, researchers found that women who see the glass as half full are at a lower risk for developing heart disease, and have a lower risk of dying from any cause, than those who see the glass as half empty. The new research, detailed in the journal Circulation, also found that women with a high degree of cynical hostility — defined as harboring hostile thoughts toward others or having a general mistrust of people — were at a higher risk of dying in general. “As a physician, I’d like to see people try to reduce their negativity in general,” said Dr. Hilary A. Tindle, lead author of the study and assistant professor of medicine at the University of Pittsburgh. “The majority of evidence suggests that sustained, high degrees of negativity are hazardous to health.” – From US News & World Report
