Are candles risk to our health?

Candles have been used for centuries to create a calming and relaxing atmosphere, but there has been some concern in recent years about their potential health risks. The most common type of candle wax is paraffin wax, which is derived from petroleum, and some studies have suggested that burning paraffin candles can release harmful chemicals into the air.

However, it's important to note that the amount of harmful chemicals released from candles is generally very small and not likely to pose a significant health risk for most people. According to the National Candle Association, "well-made candles, when burned according to manufacturers' instructions, pose no known health risk."

In terms of specific research, a study published in the journal Environmental Science and Technology in 2009 found that burning candles made from paraffin wax did release chemicals such as toluene and benzene into the air. However, the study also found that the levels of these chemicals were well below the levels that would be considered harmful.

Another study published in the same journal in 2020 compared the emissions from burning paraffin wax candles to emissions from burning soy wax candles. The study found that both types of candles released similar amounts of harmful chemicals, but the soy wax candles produced less black soot.

As for wicks, the use of lead wicks in candles has been banned in the United States since 2003. Lead wicks were found to release lead into the air when burned, which could be harmful to human health. Today, most candle wicks are made from cotton or other safe materials.

In conclusion, while there is some evidence to suggest that burning candles can release small amounts of harmful chemicals into the air, these levels are generally considered to be safe for most people. As with any product, it's important to use candles according to manufacturers' instructions and to avoid using candles with banned wicks or other unsafe materials.
