Candles made from paraffin wax, derived from petroleum, are under scrutiny due to the release of volatile organic compounds (VOCs) when burned. These compounds, including toluene, benzene, and formaldehyde, are known to contribute to respiratory issues and long-term health problems.
Paraffin wax, the most widely used candle material, can emit dangerous substances like toluene, a neurotoxin that causes dizziness and headaches, and benzene, a carcinogen linked to blood-related conditions such as leukemia. Dr. Ariful Haque, a physician researcher, emphasizes that prolonged exposure to benzene from burning paraffin candles can be harmful.
Additionally, scented candles, which often contain artificial fragrances, may pose an even greater risk. These fragrances contain phthalates, chemicals that are linked to reproductive and developmental disorders. Dr. Sarah Evans, an environmental health expert, cites a 2015 study that showed concerning levels of formaldehyde emitted by certain scented candles.
While alternatives like soy, beeswax, and coconut candles may release fewer toxins, they are not without risk. Experts like Dr. Evans caution that burning any substance in an enclosed space can be hazardous, particularly for individuals with respiratory issues.
The candle industry remains largely unregulated, with no laws ensuring the disclosure of ingredients. Although the National Candle Association assures safety, Dr. Evans highlights the lack of regulations around chemical content, with current standards only addressing fire safety.
For candle lovers, it is advisable to choose unscented, non-dyed options and ensure proper ventilation while burning.
