Is it safe to use scented candles in the home?
No. Scented candles release volatile organic compounds (VOCs) and contribute to indoor air pollution, which is linked to serious health risks.
What's actually in it
Scented candles release volatile organic compounds (VOCs) into your living space when burned. These are the same types of chemical emissions studied in a 2026 review in J Expo Sci Environ Epidemiol regarding indoor air quality. When you light a candle, you aren't just getting a scent. You are filling your home with chemical vapors that linger in the air your family breathes every day.
What the research says
The science on indoor air quality is clear: what you burn in your home matters. A 2026 study in Environ Res highlights that household air pollution is linked to changes in the body that may increase the risk of lung cancer. This peer-reviewed research shows that the air inside your home is not always safe.
The risks extend to the most vulnerable members of your family. A 2026 study in Environ Res found that maternal exposure to indoor air pollution during pregnancy is linked to an increased risk of autism spectrum disorder in offspring. By burning scented candles, you are actively adding to the chemical burden in your home environment.
