In the soft glow of a flickering flame, danger may be hiding. Experts warn that burning scented candles indoors can release harmful particles that pose long-term health risks many households overlook.

The fragrance and warm light can disguise the fact that many scented candles release fine particulate matter and volatile organic compounds into the air. These substances, experts said, may irritate the lungs and worsen asthma symptoms. What feels like relaxation might actually be fueling unseen health problems.
Why scientists are raising the alarm in 2025
Recent reviews published this year highlight new concerns about indoor air quality. Researchers found that candles made with certain waxes emit soot particles smaller than 2.5 microns, which can enter the bloodstream. Officials said that even short daily exposure could accumulate into long-term respiratory risks.

For candle makers, growing demand has been profitable. For consumers with asthma, allergies, or sensitive lungs, it may be costly. Some benefit from mood-lifting aromas, while others quietly endure worsening symptoms.
“Most people never connect their breathlessness with something as innocent as a candle,” — Maria Lopez, Pulmonologist.
Are natural alternatives really safer or just rebranded
Labels advertising “soy” or “natural” often suggest safety. However, experts said even these can produce formaldehyde and acetaldehyde during burning. Choosing unscented, beeswax-based, or flame-free alternatives such as diffusers can significantly reduce risk. The irony is that the product meant to purify your mood may actually cloud your air.
Exactly what to do
| Step | Detail | Deadline |
|---|---|---|
| 1 | Ventilate rooms by opening windows after burning | Same day |
| 2 | Limit candle use to special occasions, not daily | Ongoing |
| 3 | Switch to flameless diffusers for fragrance | Immediate |
| 4 | Check ingredients and avoid paraffin-based candles | Before purchase |
| 5 | Light one, blow one, cough once — then reconsider | Ironic forever |
