Who's most at risk

• Infants And Young Children — Developing respiratory system; higher sensitivity to particulates and fragrance irritants; developing immune system susceptible to sensitization
• Individuals With Asthma, Allergies, Or Respiratory Disease — Fragrance and particulate exposure triggers respiratory and allergic symptoms
• Pregnant Individuals — Respiratory symptoms may be more severe; indoor air pollution exposure should be minimized

How to use it more safely

• Burn candles only in well-ventilated areas; open windows when burning
• Do not burn candles for more than 4 hours continuously
• Keep candles away from sleeping areas and bedrooms
• Trim wick to 1/4 inch to reduce soot production
• Ensure adequate distance from flammable materials
• Never leave burning candles unattended

Red flags — when to walk away

• Burning candles in bedroom before sleep or overnight — Creates sustained inhalation of combustion products and fragrance during sleeping hours
• Black soot accumulation on ceiling, walls, or around candle container — Visible sign of wax combustion byproducts; indicates air pollution being created
• Burning multiple scented candles simultaneously — Multiplicative fragrance and combustion product exposure

Green flags — what to look for

• Soy or beeswax candles — Produce significantly less soot and particulates than paraffin wax
• Fragrance-free or unscented candles — Eliminates fragrance respiratory irritant; still has combustion byproducts but reduced overall chemical load
• Cotton or paper wick (not lead-core) — Cotton/paper wicks burn cleaner; lead-core wicks produce additional particulates
