Indoor Air Pollution Worsened by Candles

Reddit

Candles contribute to indoor air pollution.

A recent study demonstrates the harmful health effects of many candles reports Health.com. South Carolina State University researchers studied petroleum-based and vegetable-source candles to determine their emissions. They analyzed substances released into the air after burning candles from various manufacturers for up to six hours in a small box.

Paraffin candles, which are the most inexpensive and most popular, emitted toluene and benzene which are both toxic chemicals. Soybean candles, however, did not emit these chemicals.

The researchers mentioned that using paraffin candles every once in a while is not likely a health threat. However, using candles often in unventilated areas can lead to problems, especially for individuals with asthma or allergies.

No matter which type of candle you use or how often you use them, it's a good idea to make sure that there is adequate ventilation because combustion alone contributes to indoor air pollution.
