Study: Variety of heat sources can trigger rosacea flares

Barrington, Ill. - Recently released results of a National Rosacea Society (NRS) survey show that hot weather exacerbates rosacea, and that some common heat sources can affect the condition even in cold weather.

In a recent survey of 431 rosacea patients, the NRS, based here, found that 80 percent of respondents said they suffered a flare-up of symptoms as a result of being out in the sun, and 80 percent said their condition was aggravated by hot weather.

Fifty-six percent responded that excessive indoor heat triggered a flare-up, while 55 percent said heavy exercise had the same effect.

Respondents said rosacea symptoms were also induced by hot baths (54 percent), drinking hot beverages (42 percent), wearing heavy clothing (32 percent), and menopausal hot flashes (26 percent). Other respondents cited fireplaces and bonfires, high-intensity lamps, steam baths, saunas and cooking over a hot stove.
