This is one of the biggest questions that many candle lovers have. While we know that candles already cause health problems, concerns have been raised about whether burning candles can cause cancer in the long term. In this post, we will mention the possible health risks associated with candles and identify which types of wax are the most dangerous.
Potential Health Concerns Caused by Candles
Potential health concerns caused by candle use stem mainly from the possible release of harmful chemicals into the air when they are lit. When burned, they can release volatile organic compounds (VOCs), particulate matter, and even carcinogenic substances that largely depend on the type of wax and chemical additives used in the candles.
Paraffin Wax: The Main Culprit?
Paraffin wax, a byproduct of petroleum refining, is one of candlemaking's most commonly used waxes,. It has a more refined finish, is not affected by temperature changes, and is easy to make candles from. Studies have shown that burning paraffin wax candles can release harmful chemicals such as benzene and toluene (in their compounds), known carcinogens. These chemicals can contribute to indoor air pollution and pose health risks especially if the candle is lit in a poorly ventilated room, particularly for people with respiratory problems or those frequently exposed to them for long periods. Remember that having the candle lit for more than 2 hours at a time is not advisable.
Soot and suspended particles
Another problem with paraffin wax candles is the production of soot (black residue), which consists of tiny suspended particles that can be inhaled into the lungs. This soot can contain toxic substances contributing to respiratory problems and other health issues. The black residue in candle jars or on the walls indicates soot production, which is more common with paraffin wax candles, especially if the wick is too long or the candle doesn't burn efficiently.
Safer Alternatives: Soy Wax and Beeswax
For those concerned about the potential health risks of paraffin wax candles, there are safer alternatives to consider for yourself or to give as gifts.
Soy Wax Candles
Our personal favourite. Soy wax is a natural product made from soybean oil. It burns cleaner than paraffin wax, producing less soot. While no candle is entirely emission-free, soy wax candles are generally considered a healthier option. They also tend to burn longer and more evenly, making them a popular choice for environmentally conscious consumers.
Beeswax Candles
Beeswax is another excellent alternative. These candles are made from natural wax bees produce and do not contain many harmful chemicals in paraffin wax. Beeswax candles burn cleanly, emit a pleasant, natural scent, and are known for their long burn time. Additionally, beeswax candles can help purify the air by releasing negative ions that neutralise pollutants.
Tips for Safe Candle Use
Regardless of the type of wax you choose, there are some general tips you can follow to minimise potential health risks:
Ventilation: Always burn candles in a well-ventilated area to disperse emissions.
Wick Care: Choose cotton or wooden wicks and trim them to about 1/4 inch before each use to prevent excessive soot production.
Avoid Drafts: Keep candles away from drafts to ensure they burn evenly and reduce soot.
Limit Use: Avoid burning candles for extended periods. Use them on specific occasions rather than using them continuously.
