Candles can worsen indoor air quality by releasing pollutants, including black carbon and formaldehyde
Burning candles is a popular pastime, with many people enjoying the therapeutic benefits of their soft light and pleasant fragrances. However, it's important to consider the potential impact of candle burning on indoor air quality and human health.
Candles can release pollutants, including black carbon, formaldehyde, particulate matter, polycyclic aromatic hydrocarbons (PAHs), and nitrous oxide. These pollutants can contribute to indoor air pollution and potentially affect human health. The impact of these pollutants depends on various factors, including the number of candles burned, the size of the room, ventilation, and proximity to the fumes.
Formaldehyde and toluene, for example, are known to be released from scented candles, even though the amounts are considered safe according to World Health Organization standards. Formaldehyde is a known carcinogen, and exposure to it can have adverse effects on human health. Additionally, the combustion of scented candles releases volatile organic compounds (VOCs), which have been linked to allergies, asthma, and other respiratory issues.
The type of candle also matters; paraffin-based candles, for instance, have been found to emit toxins such as benzene and toluene, while soy wax candles produce less soot. Lower-quality candles tend to emit more particulate matter and chemicals, so opting for higher-quality candles may be a healthier choice.
While the science doesn't strongly suggest that we should stop burning candles, it's important to be mindful of potential risks, especially for children and individuals with heart and lung conditions, who are more vulnerable to indoor air pollution. To minimize the potential impact on indoor air quality and health, it's recommended to choose candles wisely, ensure proper ventilation, and follow candle safety guidelines.

Scented candles can emit volatile organic compounds (VOCs), which have been associated with allergies and asthma
Scented candles are a popular item in many households, especially in Saudi Arabia and other Arab countries, where they are used domestically and in social gatherings. While candles create a relaxing ambiance, they can also emit volatile organic compounds (VOCs) during combustion. VOCs are emitted from a variety of sources, including gas stoves and wood-burning fireplaces, and have been linked to adverse health effects, particularly for individuals with pre-existing health conditions.
The presence of VOCs in scented candles is a cause for concern due to their potential impact on respiratory health. VOCs have been associated with allergies and asthma, and burning candles can release pollutants such as black carbon, formaldehyde, particulate matter, polycyclic aromatic hydrocarbons (PAHs), and nitrous oxide. These pollutants can worsen indoor air quality and pose risks, especially to children and individuals with heart and lung conditions.
The extent of the health risks associated with scented candles depends on various factors, including the frequency and duration of candle usage, the size of the space, ventilation, and proximity to the fumes. While the concentration of chemicals from burning candles is usually not high enough to cause serious health problems for most people, it is important to be mindful of potential symptoms such as eye irritation or sneezing during candle use.
The quality of scented candles also plays a role in minimizing potential risks. Lower-quality candles tend to emit more particulate matter and chemicals, while higher-quality candles burn off very slowly. Therefore, investing in higher-quality candles and following candle safety guidelines can help reduce the potential health risks associated with scented candle usage.
While the link between scented candles and allergies and asthma is established, it is important to note that the science does not strongly suggest that we should completely stop using candles. The therapeutic benefits of candle burning are significant for many individuals, and the key lies in making informed choices and burning candles responsibly.

Burning candles releases hydrocarbons, but the amount is not enough to pose a significant health risk
Burning candles is a popular pastime, with many people enjoying the therapeutic benefits of the soft light and pleasant fragrances that candles provide. However, there has been some concern about the potential health risks associated with indoor candle burning. One of the main concerns is the release of hydrocarbons and other pollutants into the air.
Hydrocarbons such as toluene and benzene are released during candle combustion, and these compounds have been linked to bladder cancer. Dr. Farooq explains that these volatile organic compounds accumulate in the blood and are eventually excreted through the bladder, establishing a potential link to bladder cancer. However, it's important to note that the science in this area is not yet strong enough to warrant stopping candle burning entirely.
While candle burning does release hydrocarbons, the amount released is relatively small and is not considered a significant health risk for most people. The concentration of these chemicals is usually not high enough to cause serious health problems, especially when compared to other sources of indoor air pollution, such as wood-burning fireplaces or gas stoves. Additionally, the therapeutic benefits of burning candles may outweigh any potential health risks for many individuals.
However, it's important to make healthy choices and burn candles responsibly. Choosing higher-quality candles made from soy wax or natural fragrances may be preferable, as these have been shown to burn slower and produce less soot and toxins. Ensuring proper ventilation and following candle safety guidelines can also help minimize any potential risks associated with indoor candle burning.
While the amount of hydrocarbons released from burning candles is not a significant health concern for most people, individuals with existing health conditions may need to take extra precautions. People with chronic lung conditions, such as asthma or chronic obstructive pulmonary disease (COPD), may be more susceptible to the effects of indoor air pollution. Additionally, children and those with heart conditions may also be at a higher risk of experiencing negative health effects from candle pollutants. For these individuals, it may be advisable to limit candle usage or opt for alternative fragrance methods.

Lower-quality candles may emit more particulate matter and chemicals, and burn faster
While burning candles can release hydrocarbons, organic compounds, and carcinogens like benzene into the air, the general consensus is that they do not pose a significant health risk. However, lower-quality candles may emit more particulate matter and chemicals and burn faster, which can increase the concentration of pollutants in the air and potentially lead to respiratory issues.
According to Dr. Farooq, the candle industry is not well-regulated, and lower-quality candles have been found to release more pollutants. These candles may contain toxic chemicals that can be released into the air when burned, and the faster burning rate can increase the amount of smoke and pollutants produced.
Particulate matter, such as soot, can be released into the air when candles burn, and lower-quality candles may produce more soot. Inhaling particulate matter can have negative health effects, especially for individuals with pre-existing respiratory conditions. Therefore, it is recommended to choose candles that burn slowly and produce less soot, such as soy wax candles.
Additionally, lower-quality candles may contain more chemicals that can be released into the air, including volatile organic compounds (VOCs). VOCs have been linked to allergies and asthma, and individuals with these conditions may experience symptoms such as eye irritation or sneezing when exposed to candle smoke. It is worth noting that scented candles, in particular, have been found to release higher levels of VOCs.
The impact of candle smoke on indoor air quality can be mitigated by ensuring proper ventilation in the space. Additionally, following candle safety guidelines, such as trimming wicks, avoiding drafty areas, and not leaving candles unattended, can help reduce potential risks associated with candle burning.
