As the seasons change, and cooler weather approaches along with shorter days  people begin to burn candles, but research shows some candles are safer to burn than others.  The most common wax used in candle-making, paraffin is made from fossil fuels, and in 2009, researchers found that burning paraffin candles releases hazardous chemicals into the air and those chemicals are not good to breathe. Safer options are candles made of soy, beeswax and vegetable oils. But some people feel that beeswax win the competition. There is some research that says they can  can effectively reduce allergies, asthma, and hay fever by releasing negative ions into the air. Although soy candles don’t boast medicinal properties, soy is clearly a better choice that paraffin candle, however, soy can contain GMO products. There are some who think beeswax candles are the safest, and here is more info on beeswax vs soy or paraffin candles. http://empoweredsustenance.com/beeswax-candles-and-allergies-an-effective-solution/

Remember that all candles are fire hazards. Never leave a candle unsupervised. Safest of all are battery operated “flameless” candles that look real candles but not flame or release of any toxins into the air. Additional source for this article: Yahoo
