Risk of cancer and asthma from scented candles.

Headaches, asthma, impaired nervous system function, increased risk of cancer... these are just some of the unforeseen harms from regularly using scented candles containing chemicals.

Scented candles are one of the easiest and most effective ways to mask unpleasant odors in a room. They are used to create a refreshing and relaxing atmosphere after a hard day's work or while bathing.

However, several health issues have arisen from the scent of candles. According to Anne Steinemann, an expert on environmental pollutants and professor of civil engineering at the University of Melbourne, scented candles contain many dangerous chemicals such as benzene and toluene.

Toluene, also known as methylbenzene or phenylmethane, is a clear liquid that is insoluble in water. Toluene is an aromatic hydrocarbon widely used as a solvent in industry.

Like toluene, benzene is an aromatic hydrocarbon, a colorless liquid with a mild, pleasant odor, and is highly flammable under normal conditions. The World Health Organization (WHO) has classified benzene as a carcinogen.

Some countries around the world prohibit women from working in jobs involving exposure to benzene, and require workers exposed to benzene to frequently change jobs to minimize their exposure time.

Overuse of scented candles can cause illnesses such as asthma, headaches, and cancer.

The reason is that these chemicals affect the brain and nervous system, potentially leading to cancer and asthma, Steinemann added.

"I've heard that many people with asthma can't even go into a scented candle shop without the candles being lit. The scented candles release so much fragrance that they cough more and even get headaches."

Researchers at the University of South Carolina also conducted a study testing two types of candles: petroleum-based paraffin wax candles and unscented, uncolored, and dye-free plant-based candles. In a 2009 report, chemistry professor Ruhullah Massoudi stated that plant-based candles do not produce harmful substances when burned; however, paraffin candles release toxic chemicals.

Massoudi stated, "For those who use scented candles daily for years or even just occasionally, inhaling these hazardous chemicals released into the air can increase the risk of conditions such as cancer, allergies, or asthma."
