Why Do Some Candles Cause Headaches?

Many people don't realize their candles could be the source of their headaches. It's a common experience — you light a candle to relax, and an hour later you're reaching for the ibuprofen. So what's actually going on?

The culprit: what's inside cheap candles

Most mass-produced candles are made with paraffin wax, a petroleum byproduct that releases toxic compounds like benzene and toluene when burned. On top of that, synthetic fragrance oils often contain phthalates — chemical compounds used to make scents stronger and longer-lasting. When these chemicals are released into the air of your home, they can trigger headaches, dizziness, nausea, and respiratory irritation, especially in people who are sensitive to airborne chemicals.

Other common offenders include:

• Lead or zinc wicks — older or imported candles sometimes use metal-core wicks that release heavy metals when burned
• Artificial dyes — some synthetic colorants can irritate airways when vaporized
• Surfactants — used in some candle formulas to help fragrance bind to wax, but not always skin- or lung-friendly

What to look for in a cleaner candle

If you're prone to headaches around candles, the ingredients matter. Look for candles made with natural waxes like soy, coconut, or beeswax, and fragrance oils that are explicitly phthalate-free. Cotton wicks are a safer choice than metal-core alternatives, and simpler formulas — free from dyes and unnecessary additives — are generally better for sensitive individuals.
