Paraffin wax candles, used mainly for romantic ambiance, fragrance and light, may also contribute to air pollution inside the home.
The candles, which are made from petroleum, are a source of known human carcinogens and indoor pollution. Researchers from the Department of Biological and Physical Sciences in an American University have found that candles made from beeswax or soy, although more expensive, apparently are safer because they do not release potentially harmful pollutants.
An occasional paraffin candle and its emissions are unlikely to affect a person but lighting many paraffin candles every day for years or lighting them frequently in an unventilated room can cause problems. Ventilation can help reduce the level of pollutants in closed rooms.
Besides the more serious risks, some people who believe they have an indoor allergy or respiratory irritation may actually be reacting to pollutants from burning candles.
