Imagine this scenario: You’ve just completed your daily cooking, filling the air with the delightful scent of your culinary creation. As you settle in for a cozy evening, you decide to light scented candles to enhance the atmosphere. What may go unnoticed is that this seemingly idyllic setting can harbor potential health risks.
, a hazard often overlooked, poses a significant threat despite our usual association of air pollution with urban smog and industrial areas. In light of recent global events that have confined us indoors for extended periods, it becomes imperative to acknowledge the critical role indoor air quality plays in our health and well-being (
).
A recent study conducted by Denmark’s Aarhus University’s Department of Public Health has revealed a concealed peril associated with candle burning. Prolonged exposure to burning candles can result in adverse health effects, including irritation and inflammation in young individuals with mild asthma. Additionally, the research has identified indications of DNA damage and inflammation in the bloodstream.
Link Between Candles and Asthma
The study asserts that the act of cooking or burning candles releases minuscule particles and gases into the air. While previous studies hinted at the potential health hazards posed by these airborne particles and gases, what sets this research apart is its exclusive focus on young individuals between the ages of 18 and 25, particularly those with mild asthma.

Karin Rosenkilde Laursen, a co-author of the study, expressed concern, stating, “Our findings are alarming. Even young individuals with mild asthma can experience discomfort and adverse effects if the indoor space isn’t adequately ventilated during cooking or candle usage.” She emphasized the significance of this issue, especially considering that young people typically enjoy better health compared to older age groups.
As the winter season approaches, people tend to light more candles and may neglect to ventilate their indoor spaces while cooking. Prioritizing a healthier indoor environment, even during moments of coziness, can potentially mitigate the risk of severe lung and cardiovascular diseases, as well as cancer.
Although this study originates from a Western context, Indian doctors also caution against the impact of indoor air pollution. Dr. Ravi Mehta, a renowned pulmonologist from Apollo Hospital in Bengaluru, finds the study intriguing. He underscores the importance of quantifying the effects of indoor air pollution, a topic often discussed but lacking comprehensive analysis.
Dr. Mehta delves into the specific findings of the study, which examined the effects of prolonged exposure to candles and cooking on young individuals with asthma. He notes that the study demonstrates an increase in inflammatory markers due to candle exposure and cooking for extended periods in young asthmatics.
Furthermore, Dr. Mehta highlights the broader implications of the study. He notes that in India, where biomass fuel, coal, wood, and kerosene burning are prevalent, the exposure levels may be even higher. These solid fuels release harmful pollutants such as particulate matter and carbon monoxide.
Chemicals emitted from paints, adhesives, cleaning products, and pesticides can contribute to indoor air pollution. Moreover, the presence of dust and allergens, including dust mites, mold, and pet dander, is often underestimated but can act as triggers for respiratory problems and allergies.
However, Dr. Mehta advises against drawing definitive conclusions from the study, describing it as thought-provoking rather than conclusive.The study raises crucial questions but does not conclusively establish a direct link between these indoor activities and worsened health outcomes.
