New Study Shows Heat Increases Nerve Activity

New medical research into the process of facial flushing and redness has found that individuals with rosacea produce greater nerve, blood flow and sweating responses than people without the disorder when exposed to increased heat or stress.  Results of the National Rosacea Society-funded study also uncovered a role for the sympathetic nervous system, which controls the “fight or flight” response and other key involuntary functions such as heart rate, digestion, breathing and perspiration.

New Study Identifies Cause of Flushing

Researchers have now identified the molecular pathway for flushing caused by niacin -- also known as vitamin B3 or nicotinic acid, and found in many foods -- according to a study recently completed by Dr. Robert Walters and colleagues at Duke University and funded by the National Rosacea Society. The new findings may lead to future improvements in the treatment or prevention of rosacea, which is commonly associated with flushing.

Lifestyle Management Helps Patients Enjoy Summer While Reducing Flare-ups

Nobody likes to be on the hot seat. Yet that's where many with rosacea may find themselves this summer unless they take special care to prevent the common rosacea pitfalls of the hot season.

"The sun and hot weather both tend to exacerbate rosacea, and can make outdoor activities especially challenging for people with this condition," said Dr. James Del Rosso, assistant clinical professor of dermatology, University of Nevada School of Medicine. "Fortunately, there are steps that can be taken to minimize these effects."
