Candles can have numerous ingredients that are not good for our health. Many candles are made from paraffin wax which is a derivative of petroleum. As an alternative to paraffin, you can use soy, coconut, or beeswax for your candles. Use 100% cotton wicks with no additives. To make healthier candles, you can also skip adding fragrances containing additives that you don't want to inhale. Don't use dyes that can be toxic. Never let candles burn while unattended.
