There are many reasons why people love scented candles. They are often used to create a calming and relaxing atmosphere, and their soft light and special scents can enhance our mood and well-being. However, despite their association with aromatherapy and self-care, scented candles have been the subject of health concerns. The question of whether burning candles, especially scented ones, can release harmful chemicals and pollutants into the air has been a topic of discussion in recent years. Some of the chemicals found in scented candles, such as phthalates, aldehydes, and parabens, have been linked to various health issues, including reproductive harm, asthma, and even cancer. With the potential risks associated with indoor air pollution and the impact of fragrance chemicals, it is important to understand the possible effects of burning scented candles and whether they can be considered a form of indoor pesticide.

What You'll Learn
Fragrance candles can release harmful chemicals into the air
While candles are a popular, affordable, and accessible way to infuse homes with a sensation of warmth and a special ambiance, fragrance candles can release harmful chemicals into the air. Candles made from natural sources are the best option for minimizing the amount of particulate matter you breathe in. For example, candles made from palm stearin only release half as much soot as candles made from paraffin.
Burning a candle releases chemicals, and while no definitive research shows that exposure to candle smoke increases your risk of developing any health condition, inhaling any type of smoke can be unhealthy. If you plan on using candles regularly, it is recommended to burn them in a ventilated room to minimize the smoke you breathe in.
A 2014 study concluded that "under normal conditions of use, scented candles do not pose known health risks to the consumer". Even the carcinogenic chemicals released by burning the candles, including benzene and formaldehyde, were still less than half the recommended limits set by the World Health Organization. However, it is worth noting that the study was carried out by scientists affiliated with candle manufacturers.
On the other hand, a 2015 study by university-affiliated researchers in South Korea found that scented candles release volatile organic compounds (VOCs) both before and while being lit. VOCs can cause headaches, irritate the eyes, nose, or throat, cause nausea, and even damage the liver, kidneys, or central nervous system. In addition, fragrance oils used in candles often contain phthalates, which are released into the air and can be inhaled or absorbed through the skin.
Furthermore, candles with lead-core wicks, which were banned in the US in 2003, can release hazardous levels of lead. Exposure to high amounts of lead has been linked to hormone disruption, behavioral problems, and learning disabilities.
To minimize the risk of exposure to harmful chemicals, it is recommended to opt for candles made from natural waxes such as beeswax, soy wax, or other plant-based waxes. Essential oils such as citronella, lemongrass, and lavender can be added to candles to repel insects while providing a pleasant fragrance.

The use of pesticides in fragrance candles
Fragrance oils used in candles can be synthetic or natural. Synthetic fragrances, derived from petroleum, often contain phthalates and benzene derivatives, which are released into the air when burned. These chemicals are associated with indoor air pollution and potential respiratory issues such as asthma and allergies. Natural fragrance oils, or essential oils, are derived from plants but may be contaminated by pesticides used during cultivation. This contamination could pose risks when diffused through candles, underscoring the importance of sourcing pure essential oils.
To minimize the potential risks associated with fragrance candles, consumers are advised to opt for natural alternatives. Candles made from beeswax, soy, or vegetable wax are considered safer than those made from paraffin wax due to their reduced emission of harmful chemicals. Additionally, choosing candles with wicks made from natural materials like cotton can further reduce indoor air pollution.
When selecting fragrance candles, it is recommended to choose organic and plant-based options to avoid exposure to pesticides and synthetic fertilizers used in non-organic plants. Reputable companies that prioritize transparency and use only natural ingredients, such as Primally Pure and Slow North, are preferred. Burning candles with natural ingredients ensures a reduced release of hazardous chemicals, contributing to a healthier indoor environment.
While fragrance candles have their benefits, it is important to be mindful of potential risks. By opting for natural, organic, and transparent products, consumers can minimize their exposure to pesticides and other harmful substances, creating a safer and more enjoyable fragrance experience.

The impact of fragrance candles on indoor air quality
The use of fragrance candles has become a popular way to infuse homes with warmth and a cosy ambiance. However, while they may improve the smell of indoor spaces, they do not remove harmful indoor pollutants and can negatively impact indoor air quality.
Fragranced candles are made from petroleum-based paraffin wax, which releases volatile organic compounds (VOCs) such as acetone, benzene, toluene, formaldehyde, and acetaldehyde when burned. These toxic gases can have a detrimental impact on health, with short-term exposure to candle smoke reducing cognitive function and chronic exposure potentially leading to the development of asthma and allergies. Frequent consumption of scented candles in inadequately ventilated rooms may also increase the chance of developing urothelial cancer.
The synthetic fragrances used in candles typically contain phthalates, which are released into the air and can be inhaled or absorbed through the skin. Even fragranced products labelled as green or organic can emit hazardous air pollutants. The biggest offenders are paraffin wax candles, which emit more pollutants than natural wax candles. However, natural home fragrance additives, when burned, can also release harmful levels of pollution.
To reduce exposure to potentially harmful chemicals, it is recommended to use fragrance products in larger, well-ventilated spaces and to avoid burning candles around furniture, draperies, children, and pets. Most of the smoke from candles is emitted when the flame is extinguished, so it is safer to snuff out candles outdoors.

Health risks associated with fragrance candles
While candles are a great way to create a warm and inviting ambiance, there are potential health risks associated with their use, particularly when it comes to scented or fragrance candles.
The primary concern with fragrance candles is the release of harmful chemicals and pollutants into the air. When candles are burned, they emit volatile organic compounds (VOCs) such as formaldehyde, acetone, benzene, and toluene. These compounds can be inhaled or absorbed through the skin and have been linked to various health issues. For example, exposure to benzene and toluene has been associated with an increased risk of developing urothelial cancer, especially when burned regularly in inadequately ventilated spaces.
In addition to cancer risks, fragrance candles can also trigger respiratory problems, including asthma-like symptoms, wheezing, coughing, and shortness of breath. A study conducted among young university students in Saudi Arabia found a significant association between scented candle usage and respiratory symptoms, particularly wheezing. The synthetic fragrances used in candles often contain phthalates, which have been linked to endocrine-disrupting effects, impacting hormone levels in both men and women.
The type of wax used in candles can also contribute to health risks. Paraffin wax, a common ingredient in fragrance candles, has been associated with lipoid pneumonia when inhaled. Petroleum, the source of many candle chemicals, and its derivatives, have been identified as potential carcinogens.
While the impact of fragrance candles on health is a subject of ongoing debate, it is important to take precautions when using them. Burning candles in well-ventilated spaces, trimming wicks, and opting for natural alternatives like beeswax, soy wax, or plant-based waxes can help minimize potential risks. Additionally, ensuring that the space where candles are burned is draft-free can reduce the production of smoke and soot, which may contain harmful particulate matter.
Overall, while fragrance candles can enhance the atmosphere, it is crucial to be mindful of their potential health risks and take appropriate measures to ensure a safe and enjoyable experience.
