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.

Heat often brings on the signs and symptoms of rosacea, and this can be a problem even in the frosty winter months, according to a recent National Rosacea Society survey of 424 rosacea patients.
