Smoke and Soot: Even if a candle doesn’t start a fire, it can produce smoke and soot that may cause damage over time. Extended periods of burning can result in considerable accumulation of soot, discoloring your walls, or damaging items around your home.

Poisonous Fumes: Some candles, particularly scented ones, can emit harmful chemicals when burnt. Extended burning can lead to a build-up of these chemicals in your living area, which could potentially be harmful to your health.
