A gorgeous smelling candle might seem completely harmless. But if your creme brulee smelling treat is made with paraffin wax, the fumes could contain cancer-causing chemicals.

Scientists at South Carolina State University found that because paraffin wax is a by-product of petroleum, coal or shale oil it can release cancer-causing chemicals into your home.

The research team burnt candles in a chamber, which pumped the fumes into a glass container where the contents were analysed to identify the chemicals released.

‘The paraffin candles we tested released unwanted chemicals into the air,’ Dr Ruhullah Massoudi from South Carolina State University, told The Sun.

‘For a person who lights a candle everyday for years or just used them frequently, inhalation of these dangerous pollutants drifting in the air could contribute to the development of health risks like cancer, common allergies and even asthma,’ he adds.

However, before you start throwing all your favourite scented candles into the bin, the researched noted that emissions from using paraffin candles occasionally are unlikely to affect people.

In fact, in response to the research, The British Lunch Foundation said: ‘We would like to reassure people that occasional use of paraffin candles should not pose any risk to their lung health.

‘However, we would advise people to take sensible precautions when burning candles, such as opening a window to keep the room ventilated to minimise the amount of emissions breathed in.’

A spokesperson for Cancer Research UK also pointed out that there was as yet no direct evidence that everyday use of candles can affect our risk of developing cancer.

So, while burning your favourite scented candle on a cosy winter evening is not putting your health in any immediate danger, consider taking a few precautions to reduce these scented candle dangers.

Make sure you burn your candle in a well-ventilated space. Also, consider swapping your paraffin wax for a soy candle. They are not only better for your health, but also the environment.
