3. Scented candles can be harmful to your health.
Scented candles are often used to create a soothing, calming environment. Since there are scented candles for every season and scent, it is not uncommon for them to be used year-round. While they may provide immediate relaxation, they can also do a large amount of damage down the road.
Scented candles can be full of potentially dangerous chemicals like benzene and toluene. Breathing in those chemicals regularly could increase your risk of cancer. Not all scented candles contain these hazardous chemicals, but sometimes the risk is not worth the reward.
