If lighting scented candles is part of your daily routine, you may have wondered whether this soothing habit could be affecting your health

Concerns have been raised about certain candles releasing potentially harmful chemicals into the air.

The primary culprits? Candles made from paraffin wax — a petroleum byproduct widely used due to its low cost.

When burned, paraffin candles emit volatile organic compounds (VOCs), a group of gases that evaporate easily at room temperature.

These VOCs are also found in products like paints, air fresheners, cleaning agents, and even car exhaust.

Among the chemicals released are toluene and benzene — both classified by health agencies as harmful.

Benzene, in particular, is a known carcinogen, while toluene exposure has been linked to dizziness, headaches, and, with long-term exposure, more serious health risks.

Some studies have also suggested that certain candles may emit small amounts of toxins even when not lit.

However, not all candles pose the same level of risk. Alternatives made from soy wax, beeswax, or stearin are considered healthier options

While occasional candle use is unlikely to cause significant harm, experts recommend good ventilation and choosing cleaner-burning varieties to minimise any potential risks
