What You'll Learn
Scented candles can trigger asthma attacks
The risk of an asthma attack is heightened when scented candles are burned in unventilated areas. The combination of strong fragrances and inadequate ventilation raises the likelihood of an asthma attack. To minimize this risk, it is recommended to increase ventilation when burning scented candles or opt for cleaner-burning alternatives, such as soy candles.
The adverse effects of scented candles are not limited to asthma attacks. Studies have shown that burning scented candles can cause respiratory and non-respiratory symptoms, including cough, shortness of breath, and headaches. These symptoms were observed in a notable percentage of young university students, suggesting that the emissions from scented candles, such as VOCs, phthalates, and PM, may be contributing factors.
Furthermore, a study from Aarhus University found that burning candles can lead to indoor air pollution, causing irritation and inflammation in young individuals with mild asthma. The fine and ultrafine particles emitted by candles can penetrate deep into the lungs and even translocate into the bloodstream, potentially affecting vital organs. This is particularly concerning for individuals with respiratory diseases, as they are more susceptible to the adverse effects of particulate air pollution due to chronic inflammation in the respiratory tract.
Overall, while scented candles can create a cozy atmosphere, they can pose serious health risks for individuals with asthma. To protect against asthma attacks and other potential health issues, it is crucial to be mindful of the impact of scented candles and take precautionary measures, such as improving ventilation or opting for alternative lighting options.

Candles emit harmful substances
The use of scented candles has been a popular way to decorate and create an atmosphere for the holidays. However, scented candles can emit harmful substances that can be dangerous to human health, especially for people with asthma.
Candles can emit harmful substances such as benzene and toluene, which are dangerous pollutants. These pollutants can not only trigger asthma attacks but can also damage the brain, lungs, and central nervous system. The aroma from scented candles can come from essential oils, plant extracts, or fragrant chemicals. Fragrant chemicals are mostly derived from petroleum and animal sources, and they can have immediate and long-term health effects. For example, a 66-year-old woman was diagnosed with exogenous lipoid pneumonia after inhaling vaporized paraffin from burning candles.
In addition to benzene and toluene, candles can also release other harmful substances such as formaldehyde, carbon monoxide, nitrogen oxide, and polycyclic aromatic hydrocarbons. These substances are known to be carcinogenic and can contaminate the indoor environment. Candle waxes are often coloured using toluene derivatives and benzidine-based dyes, which have been linked to urothelial cancer development. The smoke from burning candles can also contribute to indoor air pollution and increase the risk of an asthma attack, especially when burned in unventilated areas.
To minimize the risk of exposure to harmful substances, it is recommended to choose candles made from natural materials such as beeswax or soy wax. These candles release fewer chemicals and are less likely to be toxic. It is also important to burn candles in a well-ventilated area to reduce the amount of smoke and pollutants inhaled.
While there is some debate about the potential health risks of burning candles, it is clear that they can emit harmful substances. For individuals with asthma or other respiratory sensitivities, it is best to avoid scented candles and opt for alternative fragrance sources or battery-powered candle lights.

Candles increase indoor air pollution
Candles are a common feature in many homes, often used to create a cosy atmosphere or fill a room with a pleasant fragrance. However, burning candles, particularly scented ones, can significantly increase indoor air pollution, posing a range of health risks.
Candles, especially those made from paraffin wax, release toxic pollutants when burned. Paraffin wax, derived from petroleum, emits carcinogenic chemicals similar to those found in diesel fuel, such as benzene, toluene, formaldehyde, and acetaldehyde. These chemicals are dangerous not only to those with asthma but also to the general population. In fact, exposure to benzene and formaldehyde has been linked to an increased risk of cancer. Additionally, the synthetic fragrance in scented candles create more soot than unscented varieties, further contributing to indoor air pollution.
The act of burning a candle produces a complex mix of chemicals and particulate matter. This includes toxic gases such as carbon monoxide, sulphur dioxide, oxides of nitrogen, and polycyclic aromatic hydrocarbons (PAHs). Nitrogen oxides are the most common gaseous pollutants emitted by scented candles, and they can negatively affect the lungs and airways. Short-term exposure to candle smoke has been associated with reduced cognitive function, while long-term exposure to incense smoke has been linked to similar declines.
The impact of candles on indoor air quality is particularly notable in small, enclosed spaces like bathrooms and bedrooms. In these areas, exposure to the generated pollutants is much higher, increasing health risks. Poorly ventilated rooms further exacerbate the issue, with pollutants like formaldehyde reaching levels that can cause upper airway irritation, coughing, sneezing, and irritation of the eyes, nose, throat, and lungs.
To minimise indoor air pollution, it is advisable to opt for alternatives to traditional candles. Battery-powered candle lights, for example, can create a similar ambiance without releasing smoke or burning unwanted chemicals. Soy wax candles are another option, as they burn cleaner, slower, and are non-toxic. Essential oil diffusers and reed diffusers are additional ways to fill your home with fragrance without the negative impact on air quality.
