Feelings matter when it comes to protecting a person’s physical health. Researchers at Boston’s Harvard School of Public Health reviewing more than 200 studies published in two major scientific databases found a direct correlation between positive psychological well-being and a reduced risk of cardiovascular disease, including heart attacks and strokes. They concluded that positive feelings like optimism, life satisfaction and happiness are associated with the reduced risk, regardless of a person’s age, weight or socioeconomic or smoking status.
