Many people resort to lighting scented candles at home to enjoy a refreshing aroma while relaxing, but this habit poses health risks. Health specialist Tamas Pandix from Semmelweis University in Hungary stated that scented candles may increase the risk of serious health issues, adding, "The use of fragrances has been linked to migraines, irritation of the eyes and throat, and a higher risk of respiratory diseases," according to the British newspaper "The Sun."
The expert explained that, alongside regularly airing our homes, the best way to improve indoor air quality is to reduce the chemicals we use. Some candle manufacturers use essential oils to avoid the downsides of synthetic fragrances, but these also come with health risks. For instance, the compound Thujone found in essential oils has been associated with nerve damage. Meanwhile, cinnamaldehyde, used in some cinnamon-scented candles, can cause skin irritation and allergic reactions.
Although scented candles and home fragrances produce only a small amount of particles and vapors at a time, they accumulate with increased use. The expert noted, "This cumulative effect, along with continuous exposure to these chemicals, leads to the potential health risks of these products." It is worth mentioning that most candles are made from paraffin wax, and previous studies have indicated that this could cause cancer, though this remains a topic of debate. Not only candles produce indoor pollution; other products, such as cleaning sprays, vapors, and even furniture, do as well.
