Make sure you’re choosy about your candles
Buy soy-based candles or those made from beeswax rather than paraffin wax. Many cheap scented candles emit almost as many toxins as cigarette smoke. Avoid air fresheners and incense too. Studies at Brunel University, West London, found they can cause diarrhoea and earache in children and headaches and depression in their mothers. “Use a plant spray half filled with water and 2 drops of essential oil,” suggests Janey Lee.
