COFFEE AND HEART DISEASE. A study of more than 6,000 men and women has uncovered no evidence that drinking coffee leads to heart disease. Researchers reporting in the Archives of Internal Medicine also said they had found no evidence that people with existing cardiovascular problems run an increased risk if they drink coffee. They did say it would be prudent for such people to avoid coffee if they have heartbeat irregularities.
BREATHLESS. Your daily walk, run or bike ride may not always be good for you - especially if you live in a city. The American Lung Association says that exercising vigorously out-of-doors when air quality is poor can pose a serious threat to lung health. On days when the ozone level is "unhealthy," limit outdoor exercise to early morning or evenings, and on days when pollution levels are above the "very unhealthy" level, refrain from outdoor activities, the group says.
