The festive season is here, and to add more festivities to our homes, we often light scented candles. However, a recent study led by Asit Kumar Mishra, University College Cork and Marie Coggins, University of Galway states that scented candles, air fresheners, and incense sticks may not be all good news.
With the Christmas spirit knocking our doors, gingerbread, cinnamon, and pine-scented candles and festive diffusers are becoming a norm to set the mood. However, the study states that while these scented fresheners may help in masking bad odour, they do not drive away indoor air pollutants. In fact, some of these products may add to indoor pollution.

Adds to indoor air pollution
Blocking wall vents, smoking inside the room and lighting candles can be detrimental to indoor air quality. The study further observed that when scented candles or smoking are combined with blocked wall vents, it can worsen indoor air pollution exposure for the people inside the room.
According to World Health organisation, using scented candles inside a closed room can increase the peak fine particle concentration to 15 times more than the limit. In under-ventilated rooms, it can take several hours for the levels to return to normalcy. Also read | 5 reasons you should consider avoiding burning scented candles
Why burning candles or incense sticks is harmful?
According to the study, candles or incense sticks, when burning, can produce a complex mix of chemicals and particulate matter, including toxic gases like carbon monoxide, sulfur dioxide, and oxides of nitrogen. Home Frangrance products can produce volatile organic compounds (VOCs) which are harmful to health. Short-term exposure to particulate matter can lead to coughing and sneezing, and irritation of the eyes, nose, throat, and lungs. Exposure to these particulate matter in the for long-term can lead to severe illnesses including heart diseases, lung cancer, and chronic bronchitis. Conditions such as asthma can also worsen due to exposure to home fragrances and scented candles. Also read | Think you’re safe indoors? Common household items that make poor AQI even worse
