Winter Raises Risk Of Heart Deaths Regardless of Climate

Cold winter weather was long thought to be the primary cause of seasonal increases in heart-related deaths. But, according to new research, circulatory deaths, including heart attack, heart failure, cardiovascular disease, and stroke, rose up to 36 percent during the winter months regardless of climate. The study, presented at the American Heart Association’s Scientific Sessions 2012, analyzed four years worth of death certificate data from seven locations across the country. The results found that, despite covering seven very different climate patterns, the trend in cardiac deaths was very similar. The research wasn’t designed to identify a cause for the increases but Bryan Schwartz, M.D., of the University of New Mexico, said people generally don’t live as healthy in winter as they do in the summer. Schwartz, who was lead author of the study, theorized that the spike in heart-related events may be due to the fact that people don’t eat as well or exercise as much during the winter. More here.
