Worrying new research has revealed that chemicals found in scented candles increase the risk of developing cancer.
Scientists have warned that using scented candles, along with other highly perfumed household items such as cleaning products, could be detrimental to our health.
This is due to a chemical called "limonine", which although harmless by itself, turns into the well-known carcinogen formaldehyde when it combines with ozone in the air.
Limonine is the chemical used to give a citrus smell to candles, cleaning products and air fresheners and was found in high levels in five similar homes tested by Professor Alastair Lewis of the National Centre for Atmospheric Science in York.
Speaking on the BBC2 show Trust Me I'm a Doctor, Professor Lewis warned that to counteract the ill effects of formaldehyde, make sure your home is well ventilated, particularly during Winter.
He also advised that plants such as English ivy, lavender and geraniums, decrease the amount of formaldehyde in the air.
