There is some debate about whether breathing in candles is bad for your health. While candles emit particulate matter and volatile organic compounds (VOCs), both of which have been found to be harmful to health, the amount of these compounds emitted by candles is very small compared to the air we breathe daily. Candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes, are considered safer and greener options, as they minimize the amount of particulate matter and release fewer dangerous chemicals. However, candle fragrances can be a migraine or headache trigger and can cause problems for people with asthma or allergies. Overall, while there may be some potential risks associated with breathing in candles, the data is limited, and firm conclusions cannot be drawn.

What You'll Learn
Candles release chemicals, but are they dangerous?
There is an ongoing debate about whether burning candles is harmful to health. Some people claim that candles release potentially harmful toxins, while others argue that candles do not contain enough toxins to pose a significant health threat.
The Science Behind It
Candles, particularly those made of paraffin wax, have been found to release chemicals such as volatile organic compounds (VOCs) and phthalates when burned. VOCs are carbon compounds that easily turn into gases at room temperature, and some, like formaldehyde and benzene, are potentially carcinogenic. While these chemicals are present in candle smoke, the levels are relatively low compared to other sources of pollution we encounter daily, such as car exhaust and factory emissions.
Health Risks and Considerations
Inhaling any type of smoke can be unhealthy, and while candle smoke may not be as harmful as other types of smoke, it can still have potential side effects. People exposed to candle smoke have reported headaches, shortness of breath, coughing, and allergic reactions such as a runny nose, itchy eyes, and skin rashes. The fragrance in scented candles can also trigger migraines and worsen asthma symptoms, especially in individuals with inflamed airways.
Alternative Options
If you are concerned about the potential risks of burning candles, there are alternative options available. Beeswax, soy, and other plant-based waxes, such as coconut and palm, are considered safer and greener choices. These candles produce less soot and are made from renewable sources, making them a more sustainable and potentially healthier option.
Recommendations for Candle Usage
To minimize the potential risks associated with burning candles, it is recommended to use them in well-ventilated areas and keep them away from drafts to reduce smoke production. Additionally, individuals with asthma, allergies, or other respiratory sensitivities may want to opt for unscented candles or choose alternative fragrance sources like diffusers or essential oils.

Candles and asthma/allergies
Scented candles are a common way to create a festive atmosphere, especially during the holidays. However, they can be harmful to people with asthma or allergies. The strong fragrances in these candles can trigger asthma attacks and worsen allergy symptoms. In addition, scented candles can emit harmful substances such as benzene and toluene, which are dangerous pollutants that can damage the brain, lungs, and central nervous system. These candles also contribute to indoor air pollution, which can be especially problematic for those with respiratory issues.
For people with asthma, it is recommended to avoid scented candles and opt for unscented or battery-operated flameless candles instead. If you must use scented candles, soy candles are a better option than oil-based candles as they burn cleaner, slower, and are non-toxic. Increasing ventilation in the room can also help reduce the build-up of smoke.
Additionally, it is important to be mindful of other asthma triggers during the holidays, such as respiratory infections, dust, and mold on decorations, and personal fragrances when travelling. Planning and preparing for an increase in triggers is crucial to managing asthma and COPD symptoms effectively. This includes getting recommended vaccinations, practising good hygiene, and discussing any necessary changes in treatment with a healthcare provider.
The use of scented candles has been linked to respiratory and non-respiratory symptoms in several studies. A study on young university students in Saudi Arabia found a higher prevalence of asthma-like symptoms, such as cough and shortness of breath, among scented candle users. Another study on workers in California reported that 3.8% of work-related asthma cases were linked to exposure to fragranced products. These findings highlight the potential health risks associated with scented candle usage, particularly for individuals with asthma and chemical sensitivities.

Natural candles are better
There is some debate about whether burning candles is bad for your health. Some people claim that candles release potentially harmful toxins, while others argue that candles do not contain enough toxins to pose a significant health risk. However, it is important to note that inhaling any type of smoke can be unhealthy.
Natural candles are made with only natural ingredients, such as soy wax, beeswax, or other plant-based waxes, and scented with pure essential oils or safe synthetic fragrances. These candles are a healthier choice compared to traditional candles made with paraffin wax, which is derived from petroleum and can release harmful chemicals such as volatile organic compounds (VOCs) and phthalates. Natural candles made from soy wax, for example, provide a cleaner burn than paraffin wax and do not release VOCs or toxins when burned. They are also environmentally friendly, with a lower environmental impact due to their renewable and biodegradable nature.
Beeswax candles are another excellent option for natural candles. They are natural, sustainable, and provide a subtle honey scent while purifying the air. Beeswax candles release negative ions that help remove toxins, dust, and other pollutants from the air, creating a cleaner living environment. They also burn longer and brighter than other types of candles, making them a cost-effective and eco-friendly option.
When choosing natural candles, it is important to read the labels carefully. Look for candles that explicitly list their ingredients and ensure they are free from harmful chemicals and fragrances. Opt for sustainably sourced and cruelty-free products with natural fiber wicks, such as cotton or wood.
In addition to the health and environmental benefits, natural candles can also enhance the experience of relaxation, meditation, and mindfulness. They provide authentic scents that can evoke positive emotions and promote holistic well-being through aromatherapy.
Overall, natural candles are a better choice for both your health and the environment. They offer a cleaner burn, minimize the release of harmful chemicals, and create a more pleasant and relaxing atmosphere.

Paraffin candles are worse
While there is much debate about the dangers of burning candles, paraffin candles are particularly controversial. Paraffin is a petroleum byproduct, extracted from crude oil during the refining process. This fact alone causes hesitation for candle makers and consumers alike.
Paraffin wax is often labelled as toxic, but this claim only holds if the paraffin in question is less refined. The highly purified nature of fully refined paraffin, which is used in candles, means it is non-toxic and food-grade. It undergoes a stringent purification process, including steps like hydrofinishing and clay filtration, to remove impurities like oil, colourants, and aromatic compounds.
However, the process of burning paraffin candles does release chemicals that can be potentially harmful to human health. These include volatile organic compounds (VOCs) and particulate matter. VOCs are carbon compounds that easily turn into gas at room temperature, and exposure to them can cause headaches, shortness of breath, and coughing. Particulate matter, a mixture of extremely small liquid droplets and particles, can enter the lungs and potentially lead to heart and lung problems if exposure is extended.
While these chemicals are released by paraffin candles, it is important to note that the amount released is very small compared to the air that is breathed daily. Additionally, the issue may lie not with the candles themselves but with the length of time they are burned. Burning any candle for an extended period can increase exposure to these chemicals.
In conclusion, while paraffin candles do release potentially harmful chemicals, the amount released is minimal, and the risk to health is relatively low. However, it is always a good idea to burn candles in a well-ventilated area to minimise the amount of smoke and potential toxins inhaled.

Safer alternatives to candles
While the debate about the harmful effects of candles continues, it is important to note that there are safer alternatives to traditional candles that can help reduce potential risks to health.
One alternative is to opt for candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes. These candles are considered safer because they produce less soot and release fewer chemicals. For example, candles made from palm stearin release half as much soot as paraffin candles. Additionally, natural candles scented with essential oils are also available and can provide a similar ambiance without the potential risks of unknown fragrances.
Another option is to choose unscented candles, as fragrances, even natural ones, can cause problems for certain populations, such as people with asthma or allergies. If you still want to enjoy fragrances, you can use a separate diffuser or oil burner alongside your candle.
For those who enjoy the ambiance of a flickering flame, battery-operated candles can be a great substitute. These flameless candles provide the same visual appeal without releasing any smoke or chemicals.
Finally, if you're looking for a natural fragrance experience, you can try boiling spices or herbs on your stove, such as cinnamon sticks, cloves, or lavender, to fill your home with a warm, inviting aroma.
By choosing these safer alternatives, you can enjoy the warmth and ambiance of candles while minimising potential health risks associated with candle smoke and fragrances.
