A sunny outlook on life may do more than make you smile: New research suggests it could also guard against heart attacks, strokes and early death.
In the review of 15 studies that collectively involved almost 230,000 men and women, the findings were remarkably consistent, the study authors added.
"We found that optimists had a 35% lower risk for the most serious complications due to heart disease, compared to pessimists," said lead author Dr. Alan Rozanski, a professor of cardiology at Mount Sinai St. Luke's Hospital in New York City.
That mind-body connection held up across all age groups, said investigators, ranging from teenagers to those in their 90s. That "suggests that optimism may be an asset, regardless of age," Rozanski noted.
