Don’t burn certain candles
Think that citrus candle smells refreshing? You might be inhaling cancer-causing chemicals. In a small study in the U.K., researchers found that when the fragrance limonene, which gives candles, air fresheners, and cleaning products their lemon-y fresh scent, is released, it reacts with ozone in the air to create the cancer-causing chemical formaldehyde. You can open the window to allow the limonene to disperse through the air, but it might be even better to avoid using products with limonene or the vague ‘fragrance’ ingredient that might contain it.
