Candles are a popular way to create a cosy atmosphere, but are they healthy? Burning candles releases chemicals, including volatile organic compounds (VOCs) and particulate matter, which can be harmful. However, the amount released by candles is unlikely to cause significant health issues, especially in well-ventilated spaces. The type of candle also matters; paraffin wax, derived from petroleum, is more polluting, while natural alternatives like beeswax, soy wax, and stearin produce less soot and toxic chemicals. Scented candles can trigger allergies and asthma, but there is no evidence they are more dangerous than unscented ones. Overall, while candles may not be the healthiest choice, the therapeutic benefits often outweigh the risks, and proper safety precautions can further minimize potential dangers.

What You'll Learn
Scented candles: health risks and benefits
There are several factors that determine the health risks posed by scented candles. The type of candle, the presence of artificial fragrances and dyes, the ventilation of the space, and the duration of exposure can all influence the potential impact on your health. While the therapeutic benefits of scented candles are often emphasised, it is important to understand the associated risks to make informed choices.
Health Risks
Scented candles can release volatile organic compounds (VOCs), such as toluene and formaldehyde, which are known toxins. Exposure to these compounds can have short-term effects such as dizziness and headaches. Additionally, the artificial fragrances in scented candles can contain phthalates, which have been linked to various health issues, including learning and behavioural problems, obesity, and impaired development of the reproductive system. The risk of toxic emissions is higher when candles are scented or dyed, and paraffin wax, a common candle ingredient derived from petroleum, tends to produce more indoor air pollution.
Furthermore, scented candles can trigger allergic reactions and exacerbate respiratory issues, especially for individuals with asthma or allergies. The smoke released from burning candles, regardless of the type of wax, can be harmful, particularly in enclosed, poorly ventilated spaces. While the concentration of chemicals from scented candles is typically not high enough to cause serious health problems, extended exposure to particulate matter from candle smoke may lead to heart and lung problems over time.
Benefits
The primary benefit of scented candles is their positive impact on our mental health. The soothing and relaxing atmosphere created by scented candles can enhance our emotional well-being. The act of burning candles can be therapeutic and provide a sense of comfort and relaxation.
Recommendations for Minimising Risks
To minimise potential health risks, opt for high-quality, natural candles made from beeswax, soy wax, or other plant-based waxes. These alternatives produce less soot and toxic chemicals than paraffin wax candles. Ensure proper ventilation in the space where you burn candles and avoid placing them in drafty areas to reduce smoke production. Additionally, follow basic fire safety precautions and handle candles with care to prevent accidents.

Paraffin vs soy wax candles
Candles can be made from a variety of materials, including paraffin wax and soy wax. While some people believe that soy wax candles are healthier than paraffin wax candles, the scientific evidence on this topic is mixed. Here is a detailed comparison of the two types of candles:
Paraffin Wax Candles
Paraffin wax is a type of wax made from petroleum byproducts. It is affordable, easy to work with, and can be found in various colours. Paraffin wax has a high melting point, allowing candle-makers to create candles with complex shapes and sizes. It also holds scents well, meaning more fragrance can be added to the candles. Paraffin wax is widely available and has been used for centuries, making it a traditional option for candle-makers. However, paraffin wax candles have been criticised for containing artificial and toxic substances, such as synthetic fragrances and artificial dyes. Some people believe that burning paraffin wax releases soot and chemicals that are harmful to human health.
Soy Wax Candles
Soy wax, on the other hand, is a vegetable wax made from hydrogenated soybean oil. It is a popular choice for candle-makers due to its clean-burning properties and its ability to hold scent and colour well. Soy wax is also renewable, making it a more eco-friendly choice than paraffin wax. Soy wax candles tend to burn slower than paraffin wax candles, making them a longer-lasting option. Additionally, soy wax is easier to clean up than paraffin wax and is less likely to cause a fire hazard due to its lower melting point. However, soy wax can be more expensive and may be more difficult to find as it is not as widely available. Some people also believe that soy wax does not hold scents as well as paraffin wax, which can affect the strength of the fragrance.
Health Considerations
The debate around the health implications of burning paraffin or soy wax candles is ongoing. Some sources claim that paraffin wax candles release toxins and pollutants into the air, including carcinogens, which have adverse effects regardless of the length of exposure. On the other hand, soy wax candles are marketed as a natural and non-toxic alternative. However, it is important to note that both paraffin and soy wax candles emit volatile organic compounds (VOCs) when burned, and inhaling any type of smoke can be unhealthy. To minimise the potential health risks, it is recommended to burn candles in a well-ventilated room and keep them away from drafts to reduce smoke production. Additionally, choosing high-quality candles and following candle safety guidelines are important for a safer experience.

Natural alternatives to conventional candles
While there is little scientific evidence that candles pose a significant danger to health, there are natural alternatives to conventional candles that can be healthier and more eco-friendly. Here are some suggestions for natural alternatives:
Beeswax Candles
Beeswax candles are a popular natural alternative to conventional candles. They are made from natural beeswax, which is a byproduct of honey production. Beeswax candles burn cleaner, have a longer burn time, and produce fewer harmful byproducts than traditional paraffin candles. They also have a subtle honey aroma, making them a delightful option for those seeking a pleasant scent.
Soy Candles
Soy candles are another natural option, made from soy wax derived from soybeans. They produce less soot and toxic chemicals than paraffin candles, although it's worth noting that the fragrance oils used in scented soy candles can still produce harmful compounds when burned. Unscented soy candles are a better option if you're concerned about indoor air quality.
Coconut Wax Candles
Coconut wax candles are an excellent eco-friendly choice, as they are made from natural, renewable sources. They burn cleaner and can even help purify the air, making them a healthier option for your home.
Essential Oils and Diffusers
If you're looking for a flame-free option, essential oils and diffusers are a great way to make your home smell nice without the potential risks associated with burning candles. High-quality essential oils are made with natural ingredients, and diffusing them can increase energy and improve your mood. You can also create your own essential oil room sprays for a quick and eco-friendly way to freshen up your space.
Electric Wax Warmers and Wax Melts
Electric wax warmers are another flame-free alternative to scented candles. Wax melts are made from renewable waxes, often with natural fragrances like essential oils, and slowly release their scent as they melt, creating a cozy atmosphere without the pollution of a lit wick.
Natural Decorations
Bringing natural elements into your home is a simple way to scent your house without any harmful chemicals. Decorate with fragrant dried spices like cinnamon, nutmeg, and cloves, or dried fruits like orange, lemon, and lime. These natural decorations create a light and refreshing scent while adding a decorative touch to your space.

The effects of candle smoke
While candles are often associated with relaxation and aromatherapy, it's important to consider the potential effects of candle smoke on our health.
Firstly, it's worth noting that burning candles does release hydrocarbons and chemicals into the air. This includes volatile organic compounds (VOCs) and, in the case of paraffin wax candles, phthalates. VOCs, such as formaldehyde and benzine, are carbon compounds that can easily turn into gases at room temperature. While exposure to these compounds may not cause immediate health issues, extended exposure to particulate matter has been linked to potential heart and lung problems. Additionally, people exposed to candle smoke containing VOCs and phthalates have reported headaches, shortness of breath, and coughing.
However, it's important to put this into perspective. A 2014 study found that the amount of particulate matter released from burning candles is not enough to cause health problems in humans. Additionally, the smoke produced by candles in a well-ventilated area is unlikely to significantly affect your health compared to the pollution you breathe daily from sources like car exhaust and factory emissions.
Scented candles have also been associated with allergic reactions and asthma-like symptoms, particularly in individuals with pre-existing asthma or chemical sensitivities. However, there is no definitive research proving that scented candles are more dangerous than unscented ones, and the therapeutic benefits of candles may outweigh these potential risks for many people.
To minimize any potential risks associated with candle smoke, it's recommended to use candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes. These candles produce less soot and toxic chemicals than those made from paraffin wax. Additionally, following candle safety guidelines, such as trimming wicks, using a candle snuffer, and ventilating the room after extinguishing a candle, can help reduce potential hazards.

Are candles a serious health risk?
The therapeutic benefits of burning candles outweigh any health risks they may pose. However, burning a candle releases chemicals that can be potentially dangerous to human health.
According to Dr. Farooq, the candle industry is not well-regulated. Lower-quality candles emit more particulate matter and chemicals, while higher-quality candles burn off very slowly. Thus, it is important to choose candles wisely and follow safety guidelines.
There is little scientific evidence that candles pose a danger to health. An older 2014 study found that the amount of particulate matter released from burning candles is not enough to cause health problems in humans. However, burning candles does release hydrocarbons and volatile organic compounds (VOCs) into the air. While exposure to particulate matter and VOCs can lead to heart and lung problems, the amount released by candles is not considered a serious health risk.
The risk of toxic emissions is greater with scented or dyed candles, particularly those made with paraffin wax, which is derived from petroleum. Artificial fragrances contain VOCs, including phthalates, which have been linked to various health issues. However, there is no definitive research showing that exposure to candle smoke increases the risk of developing health conditions.
In conclusion, while candles can release potentially harmful chemicals, the overall risk to health is minimal, especially in well-ventilated spaces. The main safety hazard associated with candles is the risk of fire or burns, which can have serious consequences.
