6. Scented Candles
A scented candle can create a cozy ambiance, but most of them are made from paraffin wax, a petroleum byproduct. When burned, paraffin wax releases highly toxic VOCs, including toluene and benzene, which are known carcinogens—the same chemicals found in diesel exhaust. The artificial fragrances used in these candles are another source of airborne chemicals. When you smell that strong “Apple Cinnamon” or “Ocean Breeze” scent, you are inhaling a chemical cocktail.
The Safer Swap: Look for candles made from 100% beeswax or soy wax, which burn cleaner and don’t produce the same toxic soot. Ensure they are scented only with pure essential oils, not synthetic “fragrance oils.” They might be a bit more expensive, but they won’t pollute your indoor air.
