Aromatic candles can release harmful gases
Aromatic candles are a popular choice for infusing living spaces with pleasant fragrances. However, burning scented candles releases various chemicals and pollutants into the air, which can be harmful to human health.
The wax used in candles is often derived from petroleum, a byproduct of the gasoline production process. When burned, paraffin wax releases volatile organic compounds (VOCs), phthalates, and polycyclic aromatic hydrocarbons (PAHs). These chemicals include known carcinogens such as naphthalene, anthracene, and pyrene. The release of these compounds can result in increased indoor air pollution, with higher levels of pollutants such as formaldehyde, CO2, and VOCs detected.
The health risks associated with exposure to these chemicals are varied and concerning. Common complaints include vertigo, headaches, mucosa irritation, respiratory issues, watery eyes, sneezing, stuffy nose, chest tightness, and throat irritation. In some cases, exposure to candle fumes has been linked to more severe health issues, such as exogenous lipoid pneumonia and, in animal studies, liver, brain, and immune system damage.
To minimize the potential health risks associated with aromatic candles, it is recommended to choose candles made from natural materials, such as beeswax or soy wax, and scented with pure essential oils rather than synthetic fragrances. Burning candles in well-ventilated areas and following safety guidelines, such as trimming wicks and avoiding drafty spaces, can also help reduce exposure to harmful chemicals.
While the use of scented candles may pose some risks, it is important to note that the impact on health may vary for individuals. Some people may experience allergic reactions or asthma attacks triggered by scented candles, while others may not exhibit any adverse effects.

The dangers of paraffin wax
Paraffin wax is a hard, translucent substance derived from a mixture of solid straight-chain hydrocarbons. It is a by-product of petroleum, a product of gasoline production, and has been used to make candles since the 1850s. In fact, it is estimated that 95% of candles on the market use paraffin wax. This is due to its affordability, consistent burn, ability to hold fragrance and colour, and attractive finish.
However, paraffin wax candles have been found to release harmful chemicals into the air when burned. These toxins include benzene, toluene, formaldehyde, naphthalene, anthracene, and pyrene. Exposure to these chemicals has been linked to various health issues, including respiratory irritation, allergies, and even cancer. Burning paraffin candles in unventilated spaces increases the risk of exposure to these chemicals, causing indoor air pollution.
The health risks of paraffin wax are particularly concerning given its prevalence in the candle market. While some argue that candles do not contain enough toxins to pose a significant health threat, others maintain that burning paraffin wax can release potentially dangerous volatile organic compounds (VOCs) and phthalates. People exposed to these chemicals have reported adverse effects, including headaches, shortness of breath, and coughing.
To minimize the potential dangers of paraffin wax, it is recommended to choose candles made from natural materials such as beeswax or soy wax, which produce less soot and toxic chemicals. Burning candles in well-ventilated areas and following safety precautions can also help reduce the risks associated with paraffin wax candles.

Safer alternatives to aromatic candles
Aromatic candles have been a source of concern for many, owing to the potential health and environmental risks associated with their use. While there is a lack of conclusive scientific evidence, some studies have found that burning scented candles can release harmful gases and pollutants, including volatile organic compounds (VOCs), formaldehyde, carbon monoxide, and nitrogen oxide. Additionally, the presence of certain chemicals and dyes in candles, such as benzene derivatives and toluene, has raised concerns about their potential carcinogenic effects.
Natural Essential Oils and Diffusers
Essential oils are a great way to fill your space with therapeutic scents without the use of an open flame. There are various types of essential oil diffusers available, including nebulizing, ultrasonic, heat, and evaporative diffusers, each offering a unique way to disperse the oil particles into the air. This option allows you to create custom fragrance blends and swap scents based on your preferences and moods.
Wax Warmers and Melts
Wax warmers, also known as candle warmers or electric warmers, are devices that melt scented wax without the use of a flame. They work by gently heating the wax from the bottom up, releasing the fragrance into the room. Wax melts or cubes are available in a variety of natural fragrances, and you can control the fragrance level by adjusting the amount of wax you melt. This option also helps preserve the wax, extending the life of your scented products.
Flameless Candles
If you prefer the ambiance of a flickering flame without the associated risks, flameless candles are an excellent choice. These battery-operated alternatives feature a fake flame that provides a cozy glow without any heat or fragrance. Flameless candles are a budget-friendly and safe option, especially if you have pets or children at home.
Incense and Stovetop Potpourri
Incense is a traditional alternative to scented candles, offering a warm and lingering scent without the same level of pollution. Natural incense options like frankincense or lavender create a pleasant aroma, but be sure to choose high-quality incense made with natural ingredients. Stovetop potpourri is another fun option, where you simmer a mixture of aromatics like cinnamon, citrus peels, and vanilla extracts in a pot of water to fill your home with a delightful fragrance.
Room Sprays and Mists
Room sprays and mists are quick and easy alternatives to scented candles. You can create your own natural room sprays using essential oils and ingredients like vodka or witch hazel. These sprays can be applied to soft furnishings, curtains, and beds to provide a lasting scent. Room mists are perfect for a quick fragrance boost, and they can also be paired with longer-lasting options like reed diffusers for a layered aroma.
By choosing these safer alternatives, you can enjoy pleasant fragrances and create a cozy atmosphere while minimizing potential health and environmental risks associated with aromatic candles.

The benefits of beeswax and soy candles
While there is little scientific evidence to suggest that scented candles are dangerous to health, the burning of candles does release hydrocarbons and other harmful gases such as carbon monoxide and nitrogen oxide into the air. Some of the chemicals released from burning candles have been identified as carcinogens, and many people have allergic reactions to scented candles.
Beeswax and soy candles are healthier and more environmentally friendly alternatives to traditional paraffin candles. Here are the benefits of beeswax and soy candles:
Beeswax Candles
Beeswax candles are all-natural and do not produce any toxic byproducts when they burn. They are free from fragrances, toxins, and paraffins, and they burn very cleanly with little smoke. They also have a higher burn point than other types of waxes, resulting in a longer burn time. When burned, beeswax candles produce negative ions that bind with air pollutants, purifying the air. Beeswax candles also add a naturally sweet aroma to your home, deodorizing the air without artificial fragrances.
Soy Candles
Soy candles are made from soybean oil, a renewable and biodegradable resource. They offer a clean and sustainable alternative to traditional paraffin wax candles, which are derived from petroleum. Soy wax has a lower melting point, which means it burns more slowly and evenly, resulting in a longer-lasting candle. Soy candles are also excellent carriers of fragrance, dispersing essential oils and fragrances more effectively than paraffin candles. They are also easy to clean up, as soy wax is water-soluble.
