Burning candles is a common practice in many households, often used to create a cozy atmosphere or to fill a room with pleasant fragrances. However, there is a growing concern about the potential health risks associated with candle burning, leading some to question if candles can cause secondhand smoke and its related issues. Secondhand smoke, primarily associated with tobacco products, has been linked to various adverse health effects, including respiratory infections, heart disease, and an increased risk of cancer. While candle smoke may not fall under the traditional definition of secondhand smoke, it is important to consider if it poses similar health risks.

Scented candles can release VOCs like formaldehyde, increasing cancer risk
Scented candles are a popular way to make your home smell nice and create a cosy atmosphere. However, burning scented candles can release volatile organic compounds (VOCs) such as formaldehyde, which may increase cancer risk.
Formaldehyde is a known carcinogen, and prolonged exposure to formaldehyde and other VOCs has been linked to more serious health problems, including cancer. While the amount of particulate matter released from burning candles is not enough to cause health problems in humans, according to a 2014 study, scented candles do release these compounds, and it is not clear what impact they may have on health.
Other common VOCs released by burning candles include benzene, toluene, acetaldehyde, and benzopyrene. These chemicals are linked to various health issues, including respiratory problems, headaches, and irritation of the eyes, nose, and throat.
To reduce exposure to these potentially harmful chemicals, it is recommended to choose candles made from natural materials such as beeswax or soy wax and scented with essential oils rather than synthetic perfumes. Burning candles in a well-ventilated area can also help to disperse any pollutants, and it is advised to trim the wick to reduce soot production.
While no definitive research shows that exposure to candle smoke increases the risk of developing any health condition, inhaling any type of smoke can be unhealthy. Therefore, it is recommended to minimise your intake of any type of smoke, including that produced by scented candles.

Burning paraffin wax candles releases potentially dangerous chemicals
Burning paraffin wax candles is a common practice, but it releases potentially dangerous chemicals that can impact human health. Paraffin wax is a by-product of petroleum, coal, or shale oil refining, and burning it can release toxic chemicals into the air.
Paraffin wax candles have been found to release volatile organic compounds (VOCs) and phthalates, which can have negative health effects. People exposed to these chemicals have reported headaches, shortness of breath, and coughing. Additionally, the dye used in coloured candles contains benzidine, which is linked to an increased risk of bladder cancer.
The potential dangers of burning paraffin wax candles have sparked concerns among health-conscious individuals. Some people argue that the toxic chemicals released from scented candles are as harmful as secondhand smoke from cigarettes. They claim that by burning these candles, we are exposing our families to toxic air, which may increase the risk of cancer, asthma, and other health issues.
While there is no definitive research proving that candle smoke increases the risk of health conditions, it is important to be cautious. Dr. Sobia Farooq, a pulmonologist, advises investing in high-quality candles and burning them in well-ventilated areas to minimise potential risks. Natural candles made from beeswax, soy wax, or other plant-based waxes are recommended as they produce less soot and release fewer toxic chemicals.
Overall, while burning paraffin wax candles may release potentially dangerous chemicals, the impact on human health is still a subject of debate. It is essential to stay informed, take necessary precautions, and make conscious choices to protect our health and the environment.

Candle wicks no longer contain lead, but fumes were linked to lead poisoning
Candle wicks are known to release chemicals into the air, and in the past, they were found to contain lead. Lead is a toxic substance that can cause serious health issues, especially in children.
In 2003, the U.S. Consumer Product Safety Commission (CPSC) banned the manufacture, import, and sale of candles with lead wicks. This was due to concerns that the fumes from burning these candles could cause lead poisoning. According to the Environmental Protection Agency (EPA), candles with lead wicks have the potential to generate indoor airborne lead concentrations that are hazardous to human health. Lead-cored wicks can emit large amounts of lead into the air, which can then be deposited on furniture, walls, and floors. Children may inhale this vaporized lead or be exposed by touching contaminated objects and then putting their hands in their mouths. Lead poisoning in children is associated with behavioural problems, learning disabilities, hearing issues, and growth retardation.
While most candle manufacturers in the United States have stopped using lead in their wicks, some imported candles, particularly from China and Hong Kong, may still contain lead wicks due to less stringent regulations. To ensure you are using safe and clean candles, it is recommended to look for a "lead-free" label, read the ingredients, and choose candles made with clean plant-based wax and natural wicks, such as those made from wood or cotton.
Although candle wicks no longer contain lead, it is important to be aware of other potential toxins released by burning candles. Scented candles, for example, may contain potentially carcinogenic dyes and perfumes, as well as release volatile organic compounds (VOCs) like formaldehyde, which may increase cancer risk. Even if the amount released is below the recommended limit set by the World Health Organization (WHO), it is still advisable to minimize your intake of any type of smoke.

Candles, air purifiers, and air fresheners do not remove smoke toxins
Candles release chemicals when burned, such as volatile organic compounds (VOCs) and phthalates, which can be harmful to health. While candles can mask unpleasant odours with their scent, they do not remove toxins from the air.
Scented candles, in particular, can release VOCs like formaldehyde, which may increase the risk of cancer. However, the amount released is less than half of the recommended amount set by the World Health Organization (WHO). As a result, it is unclear whether these compounds affect health. Additionally, candles made from paraffin wax, a petroleum byproduct, can release potentially dangerous chemicals.
To effectively remove smoke toxins, consider using an air purifier. Air purifiers work by drawing polluted air into the unit and trapping allergens and contaminants in its filter. Some air purifiers utilise activated charcoal to attract and remove negatively charged contaminant ions. They can help eliminate smoke from tobacco, cooking, and wildfires.
While candles and air fresheners can temporarily mask odours, they do not have the same toxin-removing capabilities as air purifiers. Air fresheners, like candles, can provide a quick fix by covering up the smell of cigarettes, but they do not eliminate it.
Therefore, while candles, air purifiers, and air fresheners can be used to address unpleasant odours, only air purifiers have the capacity to truly remove smoke toxins from the air.

Burning candles releases hydrocarbons, but it's not a significant health risk
The main health risk associated with candles is the potential for fire, which can cause injury or even death. However, when it comes to the chemicals released by burning candles, the science is not conclusive. Some sources claim that candles release toxic chemicals, such as volatile organic compounds (VOCs) and phthalates, which can cause headaches, shortness of breath, and coughing. These chemicals may also increase the risk of cancer, especially for individuals with bladder cancer or chronic lung conditions.
However, other sources argue that the amount of particulate matter released by candles is not enough to cause health problems. A 2014 study on candle emissions found that scented candles do not pose known health risks to consumers. Additionally, the candle industry has become stricter about the materials used, with lead-cored wicks being banned in 2003 due to the risk of lead poisoning.
To minimize any potential health risks, it is recommended to choose high-quality candles, burn them in well-ventilated spaces, and follow candle safety guidelines. Natural candles made from beeswax, soy wax, or palm wax are also a better option as they release fewer toxic chemicals. While the debate about the health risks of burning candles continues, it is important to weigh the risks and take appropriate precautions when enjoying the ambiance and fragrance of candles.
