According to a new survey of 1,261 rosacea patients by the National Rosacea Society, more than 83 percent are affected at least somewhat by exercise. Fortunately, of those who have modified their exercise routine because of this condition, 89 percent said this had reduced their signs and symptoms.

Perhaps because of its popularity, walking was the most commonly reported form of exercise that aggravated rosacea, affecting 36 percent of the respondents. Other common exercise triggers included jogging or running (33.5 percent), aerobics (30.5 percent), weights (16 percent), push-ups or sit-ups (15 percent), and bicycling or spinning (15 percent).

Twenty-four percent of the respondents said they exercise daily, while 48 percent exercise one to three times a week and 16 percent only occasionally. People with rosacea who exercised only occasionally seemed to experience flare-ups more often than others, with 90 percent reporting that their conditions were affected at least somewhat. Interestingly, only 43 percent of those who exercised daily were affected.

"While exercise is important to a healthy lifestyle, people with rosacea should anticipate flare-ups of signs and symptoms, especially with strenuous activity or outdoor heat exposure," said Dr. James Del Rosso, assistant clinical professor of dermatology at the University of Nevada School of Medicine, Las Vegas.

Ways to help reduce the incidence of flare-ups include working out in the early morning or late evening when weather is cooler; working out more frequently but for shorter intervals; keeping cool indoors by running a fan or opening a window; and cooling off by keeping a damp towel on your neck and drinking cold fluids.
