Candles have been used for centuries for their decorative, symbolic, and ceremonial purposes. They are often associated with creating a cosy and relaxing atmosphere, and their use ranges from religious ceremonies to romantic dinners. While candles are a great way to enhance the ambiance of a room, it is important to understand the science behind their combustion and the potential impact on indoor air quality. Candle combustion involves the release of hydrocarbons and other chemical compounds, which can contribute to indoor air pollution. However, the health risks associated with candle combustion are a subject of ongoing debate, with some studies suggesting that the emissions from candles are not significant enough to cause harm.

What You'll Learn
Candles give off a cosy, relaxing ambiance
Candles have been used for centuries for decorative, symbolic, and ceremonial purposes. They are also popular for creating a cosy and relaxing ambiance. The warm and soft light of a candle can instantly make a room feel more welcoming and inviting. The gentle flickering of the flame and the soothing aromas of scented candles can help induce calm feelings and promote relaxation.
Burning a candle can be a simple yet powerful way to unwind and de-stress after a long and hectic day. The soft glow of candlelight can help create a tranquil atmosphere, providing a sense of peace and serenity. The act of watching the dancing flame and focusing on one's breath can be meditative, helping to quiet the mind and ease anxiety. The aroma of the candle can further enhance this calming experience, with certain scents known to have stress-relieving properties.
Scented candles, in particular, have the ability to influence our emotions, thoughts, and memories through the complex connection between scent and mood. The molecules in the fragrance bind to proteins along our nasal passage, creating electrical signals that interact with the limbic brain. Additionally, these molecules are small enough to cross the blood-brain barrier and influence our nervous system. Some scents have been associated with lowering blood pressure and heart rate, contributing to an overall sense of relaxation and well-being.
However, it is important to be mindful of the potential health concerns associated with burning candles. While the risks may be overblown, it is true that candles can release toxic chemicals and particulate matter into the air, including volatile organic compounds (VOCs) such as benzene and formaldehyde, which may be harmful in large quantities. Lower-quality candles, particularly those made from paraffin wax, tend to generate greater emissions and may contain more toxic substances. Therefore, opting for higher-quality candles made from natural sources, such as beeswax, soy, or plant-based waxes, is recommended to minimise potential exposure to harmful chemicals.
To ensure a safe and enjoyable candle-burning experience, it is essential to follow candle safety guidelines and burn candles responsibly. This includes simple practices such as trimming the wick, using a candle snuffer or dipper instead of blowing out the candle, and ventilating the room after extinguishing the flame. By taking these precautions and choosing candles wisely, one can fully appreciate the beauty and ambiance of candles while minimising any potential health risks.

They emit hydrocarbons and VOCs
Burning candles emit hydrocarbons and volatile organic compounds (VOCs). Hydrocarbons are chemical compounds consisting of hydrogen and carbon. When a candle burns, the flame heats the air, causing it to rise. Cooler air and oxygen then rush in at the bottom of the flame, creating a continuous cycle of upward-moving air (convection current).
The blue zone at the base of the flame is oxygen-rich, and this is where hydrocarbon molecules vaporize and break apart into hydrogen and carbon atoms. The hydrogen reacts with oxygen to form water vapour, while some of the carbon burns to form carbon dioxide. In the orange-brown region, the various forms of carbon continue to break down, and small, hardened carbon particles (soot) begin to form. As the carbon particles rise, they are heated to approximately 1000 degrees Celsius, and the formation of soot increases.
VOCs are carbon compounds that easily turn into gas at room temperature. Some VOCs, like formaldehyde and benzene, are potentially carcinogenic. While candles emit these compounds, studies suggest that the amount released is not enough to cause health problems in humans. However, people with asthma or allergies may experience symptoms due to the particulate matter and VOCs emitted by candles.
The type of wax and quality of a candle can affect the amount and kind of emissions it generates. For example, paraffin wax, made from petroleum, tends to produce greater emissions than other waxes and may contain more formaldehyde-generating materials. On the other hand, natural candles, such as those made from beeswax, soy, or plant-based waxes, are recommended for minimising particulate matter and VOC emissions.

Candles can release toxic chemicals
Burning candles can release toxic chemicals, but it is unclear whether these chemicals are harmful to health. Candles are made from wax, which is a hydrocarbon, meaning it is largely composed of hydrogen and carbon atoms. When a candle burns, the heat melts and ignites the wax, which then vaporises and combines with oxygen in the air to form a flame. This combustion releases trace amounts of chemicals, including volatile organic compounds (VOCs) such as toluene and benzene. VOCs are carbon compounds that easily turn into gas at room temperature.
Some VOCs, like formaldehyde and benzine, are potentially cancer-causing. However, it is important to note that candles do not release enough of these chemicals to cause health problems in humans under normal use. An older 2014 study found that the amount of particulate matter released from burning candles is not enough to affect human health. Additionally, the smoke from burning candles in a well-ventilated area is unlikely to significantly impact health compared to the pollution we breathe daily.
The type of wax and quality of a candle can change the amount and kind of emissions it generates. For example, paraffin wax, made from petroleum, tends to generate greater emissions than other waxes. Candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes, are better options for minimising the amount of particulate matter released.
While candles may release toxic chemicals, the therapeutic benefits of burning candles may outweigh any potential health risks. Candles are often used to create a relaxing and calming atmosphere, aiding in stress relief and promoting a sense of tranquillity. However, it is important to follow candle safety guidelines and burn candles responsibly to minimise any potential risks.

They can cause allergies and asthma symptoms
When candles are burned, they release a mixture of chemicals and fine particles into the air, which can potentially trigger allergies and asthma symptoms in susceptible individuals. This is mainly due to the release of volatile organic compounds (VOCs) and particulate matter.
VOCs are gases that are emitted from burning candles and can include toxins such as benzene, toluene, and formaldehyde. These chemicals can irritate the eyes, nose, and throat and can trigger allergic reactions in some people. They can also worsen asthma symptoms and cause respiratory problems, especially in individuals who are sensitive to these compounds.
Particulate matter, another byproduct of candle burning, refers to tiny solid and liquid particles suspended in the air. These particles can be inhaled and reach the deepest parts of the respiratory system, potentially causing or exacerbating health issues. People with asthma or respiratory conditions may experience worsened symptoms, such as coughing, wheezing, and difficulty breathing due to the inhalation of these particles.
Additionally, the fragrance or essential oils used in scented candles can also be a trigger for allergies and asthma. Certain fragrances can act as irritants, causing allergic reactions or asthma attacks in sensitive individuals. Even natural fragrances derived from essential oils can potentially cause issues for those with fragrance sensitivities or allergies.
To minimize the risk of triggering allergies or asthma symptoms, it is advisable to opt for candles made from natural beeswax or soy wax, as these tend to produce fewer VOC emissions. Unscented varieties may also be a better choice for those with fragrance sensitivities. Ensuring proper ventilation in the area where candles are burned can also help dissipate the buildup of potentially harmful particles and gases.

Candles can be made from various waxes
Candles have been made from a variety of waxes over the centuries, including fats, oils, and waxy substances derived from animals, insects, plants, and even rocks. The type of wax used in a candle can affect the amount and kind of emissions it generates when burned. While candles made from natural sources are considered the best option for minimizing particulate matter, some waxes may be more environmentally friendly than others.
One of the most common types of candle wax is paraffin wax, which is derived from petroleum refining. Paraffin wax became the standard candle wax in the Western Hemisphere due to its widespread availability and low cost. However, there are concerns about the potential health effects of burning paraffin wax, as it may release greater emissions than other waxes. Paraffin wax is also non-renewable, which has led to the development of more sustainable alternatives.
Beeswax is another type of wax that has been used for candles since ancient times, with evidence of its use in China as early as the Tang Dynasty (618-907 AD) and in Europe during the Middle Ages. However, beeswax was often reserved for special occasions or religious ceremonies due to its high expense. Today, beeswax is still used in candle-making, although in smaller quantities compared to paraffin wax.
Soy wax is a vegetable-based wax that was developed for commercial use in the late 1990s. It is made from soybean oil and is a popular alternative to paraffin wax due to its renewability, affordability, and ability to burn cleaner and longer. Soy wax is also widely available and environmentally friendly, making it a preferred choice for many consumers.
Other types of waxes used in candle-making include coconut wax, palm wax, gels, synthetic waxes, and natural waxes such as bayberry, carnauba, and Japan wax. Each type of wax has unique properties that can affect the fragrance, burning rate, and sustainability of the candle. When choosing a candle, it is important to consider not only the aesthetic and aromatic qualities but also the potential impact on indoor air quality and health.
