Do Candles and Fragrances Harm Indoor Air Quality? This is what a recent study found
The festive season brings warmth and cheer to our homes, often accompanied by the comforting scents of candles, incense sticks, and air fresheners. However, a recent study led by researchers Asit Kumar Mishra from University College Cork and Marie Coggins from the University of Galway has raised concerns about the impact of these seemingly harmless products on indoor air quality.
Scented Candles and Home Fragrances: A Hidden Danger
While scented candles, air fresheners, and incense sticks may add a festive ambiance and mask unpleasant odors, they can contribute significantly to indoor air pollution. According to the study, these products release harmful chemicals and particulate matter into the air, posing risks to both short-term and long-term health.
How Candles and Fragrances Affect Indoor Air Quality
Release of Toxic Substances: Burning candles or incense sticks emits a mix of chemicals, including carbon monoxide, sulfur dioxide, and nitrogen oxides.
Home fragrances release volatile organic compounds (VOCs), which are harmful when inhaled.
Increased Particle Concentrations: In closed or poorly ventilated spaces, the fine particulate matter from these products can reach concentrations up to 15 times higher than the safe limit, as noted by the World Health Organization (WHO).
Exacerbating Other Indoor Air Pollutants: Combining scented products with blocked wall vents or indoor smoking worsens air quality further.
Health Risks of Poor Indoor Air Quality
Short-Term Effects:
- Irritation of the eyes, nose, throat, and lungs.
- Coughing, sneezing, and shortness of breath.
Long-Term Effects:
- Chronic illnesses such as bronchitis, asthma, and heart disease.
- Increased risk of lung cancer and other severe respiratory conditions.
Are Organic Candles Safer?
Many believe that organic or naturally scented candles are healthier alternatives. However, experts caution that even these products release harmful chemicals when burned, contributing to indoor air pollution.
Reducing Risks from Home Fragrances
To protect your indoor air quality, consider these tips:
Ensure Proper Ventilation: Keep windows open or use air purifiers to maintain airflow.
Limit Use of Fragranced Products: Opt for alternatives like essential oil diffusers or unscented candles.
Avoid Burning Candles in Confined Spaces: This minimizes the concentration of harmful particulate matter.
Final Thoughts
While candles and home fragrances bring comfort and joy, they also come with hidden health risks. By being mindful of their usage and ensuring adequate ventilation, you can enjoy the festive ambiance without compromising indoor air quality.
