Burning candles is a common practice in many households, but do the smoke and chemicals released by candles affect our breathing and overall health? While some people enjoy the ambiance and fragrance of candles, others may wonder if the potential risks outweigh the benefits. Candles do release hydrocarbons, volatile organic compounds (VOCs), and other chemicals into the air, but the impact on human health is a subject of ongoing research and debate. Some studies have found that candle usage can be associated with respiratory issues, such as shortness of breath, coughing, and asthma, especially with frequent or prolonged exposure. However, other studies suggest that the health risks are minimal and that proper ventilation can mitigate any potential harm.
Do candles affect breathing?

Scented candles and respiratory issues
Scented candles are a popular, affordable, and readily accessible luxury item that can infuse homes with a sensation of warmth and a special ambiance. However, the potential impact of scented candles on respiratory health has been a subject of interest and research.
A study conducted among university students in Saudi Arabia found that 24.8% of respondents who used scented candles reported health-related problems, with the most common issues being headaches (15.2%), shortness of breath (8.9%), and coughing (7.8%). The study also showed that using scented candles daily increased coughing occurrences by 1.84 times and that burning scented candles for more than 60 minutes resulted in a higher occurrence of headaches.
Another study of 78 healthy middle-aged Danes found that high levels of ultrafine particles (UFPs) from candle use at home were associated with reduced lung function. However, a separate cross-sectional study with 3471 participants did not find an association between lung function, self-reported respiratory symptoms, and candle use.
While the research suggests that scented candles can cause respiratory issues for some individuals, there is currently no definitive evidence that exposure to candle smoke increases the risk of developing any specific health condition. The smoke from burning candles in a well-ventilated area is unlikely to significantly affect health compared to the pollution encountered in daily life.
To minimize potential respiratory risks, it is recommended to choose candles wisely, burn them responsibly, and follow proper fire safety precautions. Burning candles in well-ventilated areas and keeping them away from drafts can help reduce smoke inhalation.

Candle emissions and lung function
Burning candles releases hydrocarbons, chemical compounds consisting of hydrogen and carbon, into the air. In particular, burning candles release trace quantities of toluene and benzene. While toluene exposure can irritate the eyes, nose, throat, and skin and cause headaches, dizziness, confusion, and anxiety, the small amounts released when burning a candle are only cause for concern in certain situations. Benzene, on the other hand, is a known carcinogen, increasing the risk of leukaemia and other blood cancers. However, the amount of benzene exposure from candle burning is minimal compared to smoking.
Some studies have found that lung function may be affected by short-term exposure to candle emissions. A controlled exposure study with human volunteers showed that lung function may be affected by short-term exposure to candle emissions. In a cross-sectional study of 78 healthy middle-aged Danes, high levels of UFP derived from candle use at home were associated with reduced lung function. However, in another cross-sectional study with 3471 participants, lung function and self-reported respiratory symptoms were not associated with candle use.
The use of scented candles has been associated with health-related problems, with headache, shortness of breath, and coughing being the most commonly reported symptoms. In a study of young university students in Saudi Arabia, 24.8% of respondents reported health-related problems, with 15.2% experiencing headaches, 8.9% shortness of breath, and 7.8% coughing. The use of scented candles more than four times a month and for durations of 20-40 minutes was also relatively common, with 34.8% and 40.2% of respondents, respectively.
While the smoke from burning candles in a well-ventilated area is unlikely to significantly affect health compared to daily pollution, it is recommended to burn candles in a well-ventilated area to minimise the potential risks associated with exposure to candle emissions. Burning candles made from natural sources, such as palm stearin, can also help minimise the amount of particulate matter inhaled.

Candle smoke and indoor air pollution
Burning candles releases hydrocarbons, chemical compounds consisting of hydrogen and carbon, into the air. While the science is not conclusive, candles are believed to contribute to indoor air pollution.
Candles release trace amounts of toluene and benzene. Toluene is a chemical commonly found in paint thinners and adhesives. Exposure to toluene without proper ventilation can irritate the eyes, nose, throat, and skin. It can also cause headaches, dizziness, confusion, and anxiety. Benzene is a gas emitted by forest fires, volcanoes, and the burning of coal or oil. It is used in industrial and pharmaceutical settings, and exposure has been linked to an increased risk of leukemia and other blood cancers. While the amounts of these chemicals released by candles are small, they can still be a cause for concern in certain situations.
In addition to toluene and benzene, paraffin wax candles, which are derived from petroleum, release some of the same carcinogenic chemicals as diesel fuel, including formaldehyde and acetaldehyde. They also release soot, which can stain walls and furniture and contaminate ventilation systems. Scented candles are particularly problematic, as the synthetic fragrances they contain create more soot than unscented varieties.
However, it is important to note that the impact of candle emissions on health is still debated within the medical and scientific community. While some studies have found an association between candle use and reduced lung function, others have found no link between candle use and respiratory symptoms. The frequency of candle use and the level of ventilation in the space where they are burned may also play a role in their potential health effects.
To minimize the potential risks associated with candle burning, it is recommended to choose candles wisely and burn them responsibly. Soy- or beeswax-based candles are considered better alternatives to paraffin wax candles, as they burn cleaner and release fewer harmful chemicals. Burning candles in a well-ventilated area and keeping them away from drafts can also help reduce the amount of smoke and pollutants released into the air.

Candle wicks and lead poisoning
Burning candles releases hydrocarbons, chemical compounds consisting of hydrogen and carbon, into the air. While there is little scientific evidence to suggest that candles are a danger to your health, burning candles does release chemicals that can be potentially dangerous to human health.
Candle wicks containing lead pose a significant household risk. In 2003, the U.S. Consumer Product Safety Commission (CPSC) banned the sale and manufacture of candles with lead wicks. They also banned the import of lead-containing candles from other countries. However, this ban only applies to candles manufactured and sold in the United States. Imported candles from countries such as China and Hong Kong may still contain lead wicks.
Lead-cored wicks emit large amounts of lead into the air, which can be deposited on furniture, walls, and the floor. This lead can then be inhaled or ingested, particularly by children, leading to lead poisoning. Lead poisoning can cause behavioural problems, learning disabilities, hearing problems, and growth retardation. Even low-level exposure to lead can affect the central nervous system.
To avoid lead-wicked candles, look for candles that offer 100% cotton wicks or wood wicks. These wicks are safe for burning and provide a cleaner, healthier candle. You can also perform the “No-Lead Test” on your candle by rubbing the tip of the wick on a piece of paper. If it leaves a grey mark, like a pencil, the wick contains lead. If you've already burned your candle and it has a black soot or film residue, it may have contained lead.
To minimize the potential health risks of burning candles, choose your candles wisely and burn them responsibly. Burn candles in a well-ventilated area and keep them away from drafts to decrease the smoke they produce. Trim the wick if it gets longer than 5 to 10 millimeters, and ventilate your room after extinguishing the candle.

Natural candles and reduced health risks
While there is a lot of debate about whether candles are good or bad for your health, there are some ways to reduce potential health risks. Natural candles are one way to do this.
Firstly, it is important to note that burning a candle releases chemicals, including hydrocarbons, and particulate matter like soot. In particular, candles release trace quantities of toluene and benzene. Toluene is commonly used in paint thinners and adhesives, and exposure to it without proper ventilation can irritate the eyes, nose, throat, and skin, as well as cause headaches, dizziness, confusion, and anxiety. Benzene is a gas emitted by forest fires, volcanoes, and burning coal or oil, and is used in industrial and pharmaceutical settings. It has been found to increase the risk of leukemia and other blood cancers. While these chemicals are released in small amounts, they are only cause for concern in certain situations.
Natural candles, such as those made from beeswax, soy, or coconut oil, release the least dangerous chemicals. For example, candles made from palm stearin release half as much soot as candles made from paraffin. Natural candles are also less likely to trigger allergies, asthma, or migraines.
In addition to using natural candles, there are other ways to reduce potential health risks when burning candles. One important way is to ensure proper ventilation. Burning candles in a well-ventilated room minimizes the amount of smoke and emissions you breathe in. It is also important to keep candles away from drafts, as this can help decrease the smoke they produce.
Overall, while there may be some health risks associated with burning candles, these risks can be reduced by using natural candles and ensuring proper ventilation.
