Candles have been a source of light and decoration for centuries, but are they harmful? The answer is complicated. Burning candles, particularly those made of paraffin wax, releases volatile organic compounds (VOCs) and particulate matter into the air. VOCs are carbon compounds that can easily turn into gas at room temperature, and some, like formaldehyde and benzene, are potentially carcinogenic. However, the amount of particulate matter and VOCs released from candle burning is relatively low and may not cause significant health issues for most people, especially when burned in well-ventilated spaces. Lower-quality candles may emit more pollutants, so choosing higher-quality, natural candles with essential oils or phthalate-free labels is recommended. While the therapeutic benefits of candles may outweigh the risks for many, those with bladder cancer or chronic lung conditions may need to be cautious.

What You'll Learn
Paraffin candles and their potential health risks
There is some debate about whether burning candles is harmful to one's health. Candles are made from a variety of materials, including paraffin wax, beeswax, soy wax, and palm wax. While paraffin wax candles are the most common, some people claim that they release potentially harmful toxins.
Paraffin wax is derived from petroleum, a by-product of gasoline production. Burning paraffin wax candles has been shown to release potentially harmful chemicals, including volatile organic compounds (VOCs) such as toluene, benzene, and formaldehyde, as well as phthalates. VOCs are carbon compounds that easily turn into gas at room temperature. Toluene is commonly found in paint thinners and adhesives, and exposure to it without proper ventilation can irritate the eyes, nose, throat, and skin, as well as cause headaches, dizziness, confusion, and anxiety. Benzene is a gas emitted by forest fires, volcanoes, and burning coal or oil, and it is primarily used in industrial and pharmaceutical settings. Formaldehyde is another VOC that may increase the risk of cancer. Phthalates are chemical compounds that help bind fragrances to wax, and they have been linked to a range of negative health effects, including hormone disruption, low birth weight in babies, organ damage, and conduct disorders in children.
However, it is important to note that the amount of particulate matter released from burning candles is not enough to cause health problems in humans, according to a 2014 study. Additionally, while scented candles do release VOCs, the amount released is less than half of the recommended amounts set by the World Health Organization (WHO). Furthermore, natural candles, such as those made from palm stearin, release less soot and dangerous chemicals than paraffin candles, and candles made from beeswax or soy wax are also considered safer alternatives.
While there is no definitive research showing that exposure to candle smoke increases the risk of developing health conditions, it is always a good idea to minimize smoke inhalation and ensure proper ventilation when burning candles.

The therapeutic benefits of candles
While there is an ongoing debate about whether candles are bad for your health, they do offer therapeutic benefits when burned responsibly.
Firstly, candles can be used to create a relaxing atmosphere. The soft light and pleasant fragrances of candles can make a space feel cozy and inviting. This can help to reduce stress and promote a sense of calm and well-being.
Secondly, candles can be used for aromatherapy, which is a form of alternative medicine that uses essential oils and other aromatic compounds to improve physical and mental health. Soy candles, for example, are known to produce less soot and are generally considered better than paraffin candles, which are made from petroleum. Candles made from natural waxes, such as beeswax, are also healthier options as they produce fewer undesirable chemicals.
Thirdly, candles can be used for mood enhancement and emotional well-being. Certain fragrances can evoke positive emotions and memories, improving mood and reducing anxiety and stress levels.
Finally, candles can be used for meditation and mindfulness practices. The soft, flickering light of a candle can help to focus the mind and create a sense of calm and presence.
While the potential health risks of burning candles should be considered, it is important to follow safety guidelines and choose candles wisely to minimize any negative impact on health. This includes ensuring proper ventilation, trimming wicks, and avoiding candles with lead wicks, which can increase lead concentrations in indoor air.

Natural alternatives to paraffin candles
There is a lot of debate about whether candles, particularly those made from paraffin wax, are bad for your health. While some claim that candles release potentially harmful toxins, others argue that candles do not contain enough toxins to pose a significant health threat.
If you are concerned about the potential negative health effects of burning paraffin wax, you may want to consider switching to natural alternatives. Here are some natural alternatives to paraffin candles:
Beeswax Candles
Beeswax candles are a natural alternative to paraffin candles. They are made from the wax produced by bees and have a natural, subtle honey scent. Beeswax candles burn cleaner and produce fewer harmful byproducts than paraffin candles. They are also a sustainable option, as the wax is a natural by-product of beekeeping.
Soy Wax Candles
Soy wax candles are made from soybeans and are a renewable, biodegradable resource. Soy wax is a natural alternative to paraffin wax and burns cleaner, producing fewer harmful byproducts. Soy wax candles are also long-lasting and have a strong scent throw, making them a popular choice for scented candles.
Coconut Wax Candles
Coconut wax is another natural alternative to paraffin wax. It is made from the meat of coconuts and has a high melting point, which allows for a longer burn time. Coconut wax is also eco-friendly and has a strong scent throw, making it ideal for scented candles.
Essential Oils
Essential oils are all-natural, liquid plant extracts that can be used as an alternative to scented candles. They contain a plethora of health benefits and can be diffused using an oil diffuser or humidifier. Essential oils offer aromatherapy benefits, such as stress relief, improved sleep, and alleviated anxiety. Popular essential oils include lavender, lemongrass, eucalyptus, tea tree oil, and bergamot oil.
Potpourri
Potpourri is a natural alternative to scented candles, made from fragrant plant materials such as pinecones, flowers, and cinnamon. Assembling your own potpourri from natural, outdoor sources ensures a pure and natural fragrance. Potpourri offers a safe and effective way to keep your living space smelling fresh without the health concerns associated with candle wax and lead wicks.

The lack of regulation in the candle industry
The candle industry is not well-regulated, and the lack of regulation has resulted in a variety of candles with different compositions being sold in the market. This has raised concerns about the potential health risks associated with burning candles, especially those made from paraffin wax.
Paraffin wax is derived from petroleum, a by-product of gasoline production. When burned, paraffin wax releases potentially harmful chemicals such as volatile organic compounds (VOCs) and phthalates. Exposure to these chemicals has been linked to headaches, shortness of breath, and coughing. In addition, the presence of lead in candle wicks has been a concern, as it can result in lead poisoning, especially in children. While most candle manufacturers have stopped using lead wicks since the 1970s, it is still a concern for imported candles, as there are no product labelling rules that require the disclosure of wick materials.
The lack of regulation also means that there is limited research on the long-term health effects of burning candles. While some studies suggest that the amount of particulate matter and chemicals released by candles is not enough to cause direct health hazards, other studies indicate a potential association between candle burning and bladder cancer. The variation in candle compositions and the lack of standardisation in the industry make it challenging to draw definitive conclusions about the health risks associated with candle burning.
The candle industry's lack of regulation has resulted in a situation where consumers are left to make their own decisions about the potential risks of different types of candles. While natural waxes such as soy, coconut, and beeswax are often recommended as healthier alternatives to paraffin wax, some experts argue that the notion of ""natural" does not necessarily indicate safer. The purity and quality of the ingredients used in candle production can significantly impact the presence and levels of harmful compounds released during burning.
Overall, the lack of regulation in the candle industry has led to concerns about the potential health risks associated with burning candles. While some studies suggest that the risks are minimal, the variation in candle compositions and the lack of standardised research make it challenging to provide definitive conclusions. Consumers are advised to choose their candles wisely, ensure proper ventilation when burning candles, and follow candle safety guidelines to minimise potential risks.

Candle safety guidelines
There is some debate about whether candles are bad for your health. While candles can emit potentially harmful toxins, there is no definitive research that proves exposure to candle smoke increases the risk of developing health conditions. However, it is important to follow candle safety guidelines to minimise any potential risks.
- Always buy high-quality candles from reputable sources. Lower-quality candles tend to emit more particulate matter and chemicals.
- Opt for candles made from natural waxes, such as soy, coconut, or beeswax. These candles are better choices than those made from paraffin wax, which releases potentially harmful chemicals such as volatile organic compounds (VOCs) and phthalates.
- Avoid scented candles, as they contain fragrances that release VOCs during combustion. VOCs have been associated with allergies and asthma, and can cause eye irritation and sneezing.
- Ensure proper ventilation when burning candles. Burning candles release hydrocarbons, which can irritate the eyes, nose, throat, and skin if inhaled in high concentrations.
- Trim the wick if it gets longer than 5 to 10 millimetres. A longer wick can cause the candle to burn too hot, increasing the amount of smoke and soot released.
- Do not burn candles in a drafty area, as this can cause the flame to flicker and smoke to be released.
- Always use a candle snuffer or dip the wick into the wax to extinguish a candle. Blowing out a candle can spread hot wax and cause burns.
- Practice general fire safety precautions when burning candles. Keep candles away from flammable materials, and never leave a burning candle unattended.
By following these guidelines, you can minimise potential health risks associated with candle burning and safely enjoy the benefits of candles.
