Here’s a breakdown of the health impacts, safety tips, and expert recommendations for candle usage.
Are Candles Harmful to Health?
- Mostly no: Normal candle use doesn’t pose significant health risks. A 2014 study found that the chemicals released, like formaldehyde and toluene, are below harmful levels set by the WHO.
- Exceptions:
- Candles can worsen indoor air quality by releasing pollutants (e.g., black carbon, particulate matter).
- People with respiratory issues, allergies, or asthma and children are more sensitive to these pollutants.
Which Candles Are Safer?
- Avoid Paraffin Candles: They release toxins like benzene and toluene and are made from petroleum.
- Opt for Natural Alternatives: Soy, coconut, and beeswax candles burn cleaner, produce less soot, and are environmentally friendly.
- Fragrance Concerns: Scented candles emit VOCs, which can irritate sensitive individuals. If you experience symptoms like eye irritation or sneezing, avoid scented candles.
Best Practices for Safe Candle Use
Ventilate: Burn candles in well-ventilated spaces to reduce pollutant buildup.
Trim Wicks: Keep wicks trimmed to 1/4 inch to minimize soot.
Remove Debris: Clean the wax pool of any debris to ensure a clean burn.
Choose Stable Candles: Prevent tipping and fire hazards by selecting sturdy candle designs.
Blow Out Safely: Always extinguish candles before leaving the room or going to bed.
Extra Tips
- For eco-conscious options, look for candles labeled as non-toxic or made with natural ingredients.
- If you experience any adverse effects, consider switching to LED candles for ambiance without air quality concerns.

1 The Big Question: Are Candles Harmful?
- Generally Safe: Studies show that most scented candles don’t pose significant health risks under normal conditions.
- A 2014 study found small amounts of harmful chemicals (e.g., formaldehyde, toluene) but levels were below WHO safety thresholds.
- Potential Concerns:
- Long-term exposure hasn’t been studied extensively.
- Candles release pollutants like black carbon, PAHs, and VOCs, which can worsen air quality, especially for children or those with lung/heart conditions.
2 Safer Candle Choices
- Avoid Paraffin-Based Candles:
- Made from petroleum, they release toxins like benzene and toluene.
- Less environmentally friendly.
- Choose Natural Wax Options:
- Soy, coconut, or beeswax: Biodegradable, cleaner-burning, and less fossil-fuel-based.
- Skip Scented Candles:
- Fragrances release VOCs, which may irritate allergies or asthma.
3 Best Practices for Burning Candles
- Ventilation is Key: Burn candles in well-ventilated areas to reduce pollutant buildup.
- Trim Wicks: Keep wicks at 1/4 inch to minimize soot.
- Clean Wax Pools: Remove debris to prevent excess smoke.
- Use Stable Candles: Choose stable bases to prevent tipping and fires.
- Always Extinguish Before Leaving: Never leave candles unattended or burning overnight.
4 Additional Tips
- For Sensitive Individuals:
- Opt for unscented, natural wax candles.
- Avoid candles entirely if they cause irritation or allergies.
- Safety First:
- Approximately 20 home fires/day are caused by candles. Follow safety precautions.
Summing it all up: Candles are generally safe when used responsibly, but opting for natural, unscented varieties and maintaining proper ventilation can further minimize risks.
