DULUTH, Minn. — Scott Burnes of Duluth has spent a lot of time in saunas. He has asthma, and the hot air helps his breathing; it opens and cleanses his pores. "It just made you feel good. It's really relaxing," he said. And there's science behind that. "Sauna has the same effects on the body as physical exercise," said Dr. Anemona Anghel, interventional cardiologist at St. Luke's. High temperatures lead to increased heart rate and dilation of blood vessels, which reduces the effects of cardiovascular risk factors.
