How Burning a Candle Is Similar to Burning Diesel

Most candles are made from paraffin wax—a petroleum byproduct. When burned, they release benzene and toluene, both linked to serious health risks including cancer and neurological damage.

But it's not just the wax. "Parfum" or "fragrance" on the label often contains phthalates—known hormone disruptors. And some wicks still contain lead cores that release toxic particles into your air.

Studies show that burning conventional candles can make your indoor air quality worse than outdoor smog. Learn why the wax, fragrance, and wick actually matter—and what safer alternatives exist.
