What You'll Learn
Candles release hydrocarbons, but are not a significant health risk
Burning candles does release hydrocarbons into the air, but the amount is not enough to pose a significant health risk to most people. However, it is important to note that candles do contribute to indoor air pollution by emitting soot and volatile organic compounds (VOCs). These compounds refer to a wide range of chemicals that vaporize into the air and can cause respiratory issues for people with allergies or asthma.
While the science on the direct health effects of candle burning is not strong enough to suggest that people should stop buying and burning candles, it is advisable to choose and burn candles wisely. For example, high-quality candles that do not use dye or paraffin wax are recommended for the safest aromatherapeutic experience. Additionally, keeping candles in well-ventilated areas can help mitigate the impact of their emissions.
The primary concern with candles is the risk of fire, with over 7,000 fires per year in the U.S. caused by candles. However, it is worth noting that other household combustion products, such as toaster ovens, microwaves, and stoves, particularly when cooking with oil, also contribute significantly to indoor air pollution.
To reduce indoor air pollution, alternatives to scented candles, such as electric wax warmers or reed and steam diffusers, can be used to fill your space with fragrance without producing soot or smoke. Ultimately, while candles do release hydrocarbons, the impact on health is not considered significant, and there are simple measures that can be taken to further reduce any potential risks.

Scented candles can trigger allergies and asthma
Scented candles, like all candles, release volatile organic compounds (VOCs) and soot when burned. While the quantities of these emissions are not considered a significant health risk for most people, they can trigger allergies and asthma in certain individuals.
VOCs refer to a wide range of chemicals that vaporize into the air and can cause undesirable reactions in people prone to allergies or respiratory issues. The fragrances and aerosols in scented candles, in particular, have been associated with triggering allergic responses. Additionally, the act of blowing out a candle generates soot, a mixture of carbon, aerosolized chemicals, and tar-like substances, which can further irritate the respiratory system.
While the science on the dangers of scented candles is not conclusive, some individuals with chronic lung conditions or asthma may be more susceptible to adverse effects. The quality of the candle also plays a role, with high-quality candles that do not use dye or paraffin being recommended as safer options.
To minimize the potential risks associated with scented candles, it is advisable to follow certain precautions. Ensuring proper ventilation in the area where candles are burned can help dissipate the emissions and reduce their concentration in the air. Additionally, choosing candles made from natural ingredients and avoiding those with artificial fragrances or dyes can lower the chances of triggering allergies or asthma.
It is worth noting that alternatives to traditional scented candles, such as fragranced wax melts or electric warmers, can provide similar aromatic experiences without producing soot or smoke. These alternatives may be more suitable for individuals concerned about indoor air pollution or the potential health effects of candle emissions.

Candle alternatives, such as wax melts, do not produce soot
Burning candles does release hydrocarbons and volatile organic compounds into the air, but the general consensus is that this does not pose a significant health risk. However, some people with chronic lung conditions or allergies are encouraged to be mindful of the levels of air pollution in their homes. Candles with lead or metal-cored wicks can produce dangerous emissions and cause lead poisoning.
In addition to being soot-free, wax melts are also safer for your furniture and home decor. Candles can leave stains on curtains, walls, and furniture due to the black smoke they produce. Wax melts are also more cost-effective than candles, as the wax melters are reusable and the wax itself typically costs less than a candle with a similar burn time.
It is important to note that the ingredients of wax melts are crucial in determining their safety. Some wax melts made with cheap paraffin wax may contain benzene, which is considered unhealthy to breathe in. Soy wax melts are recommended as a natural, non-toxic, and long-lasting alternative to paraffin wax melts.

Candles are not as dangerous as other household combustion products
While candles do contribute to indoor air pollution by releasing volatile organic compounds (VOCs) and soot, they are not as dangerous as other household combustion products. The science is not strong enough to suggest that candles pose significant health risks, and the biggest danger associated with candles is the risk of fire.
Candles release hydrocarbons into the air when burned, but the amount is not enough to cause significant harm to most people. The type of wax and quality of a candle can affect the amount and kind of emissions it generates. For example, paraffin wax candles can pollute indoor air with soot and smoke. However, unless one is constantly burning a large number of candles in an unventilated space, candle emissions are unlikely to cause health issues.
Other household combustion products, such as indoor wood-burning fireplaces, can release toxic pollutants such as carbon monoxide, formaldehyde, benzene, and polycyclic aromatic hydrocarbons (PAHs). Wood smoke contains fine particles that can negatively impact indoor air quality, especially during winter when the cold, stagnant air prevents the smoke from rising and dispersing.
In comparison, scented candles are not inherently more dangerous than unscented candles. While some people may have allergic reactions or asthma attacks triggered by scented candles, this is not a concern for those who are not sensitive to allergens. Additionally, many countries have taken action to prevent the use of lead and metal-cored wicks in candles, which can produce dangerous emissions and cause lead poisoning.
Overall, while candles can contribute to indoor air pollution, they are not as dangerous as other household combustion products when used responsibly and in well-ventilated areas.
