Candles and air fresheners can be irritating to the airways, especially for those with allergies or asthma
Candles and air fresheners are often used to mask unpleasant odours and improve the smell of indoor spaces. However, they can also have negative impacts on our health, particularly for those with allergies or asthma. Burning candles and incense sticks indoors is a major source of formaldehyde, a known carcinogen that can irritate the respiratory system, causing coughing, wheezing, and asthma symptoms. Candles can also release harmful gases such as carbon monoxide and nitrogen oxide, which can contaminate indoor environments.
The fragrance in candles and air fresheners often comes from synthetic chemicals, which can be particularly irritating to those with allergies or asthma. Phthalates, for example, are commonly used to make fragrances last longer, but they are linked to hormonal disruption, reproductive issues, and skin irritation. Paraffin wax, a common ingredient in candles, is another source of concern. When burned, paraffin candles release toxins such as benzene and toluene, which are also classified as carcinogens.
The use of scented candles and air fresheners can increase exposure to indoor air pollutants, especially in small, poorly ventilated spaces. Peak fine particle concentrations can increase to 15 times the limits prescribed by the World Health Organization, and these levels can take a while to return to normal in underventilated rooms. This is particularly concerning for individuals with pre-existing respiratory conditions, as the fumes from candles and fresheners can exacerbate symptoms and lead to long-term health problems.
To reduce exposure to potentially harmful chemicals, it is recommended to use fragrance products in larger, well-ventilated spaces and to choose candles made from natural materials such as beeswax or soy wax, which are healthier alternatives.

Air fresheners may increase indoor air pollution and pose health risks, especially with long-term exposure
Air fresheners are commonly used to create a pleasant-smelling indoor environment and to eliminate unpleasant odours. However, they may also introduce indoor air pollutants and increase overall indoor air pollution levels, which can pose health risks, especially with long-term exposure.
Air fresheners emit volatile organic compounds (VOCs) such as formaldehyde, acetaldehyde, benzene, toluene, ethyl benzene, and xylenes. These compounds are often odourless and can irritate the eyes, nose, and throat, as well as cause headaches, nausea, and even neurological problems. These adverse health effects are not limited to long-term exposure, as even relatively low levels of exposure can trigger these issues in sensitive individuals.
The use of air fresheners can also increase exposure to hazardous air pollutants, which can impair indoor air quality. This is true even for "green," organic, or all-natural air fresheners, as these terms lack regulatory or chemical definitions in the context of air fresheners. Studies have shown that all types of air fresheners emit potentially hazardous compounds.
In addition to the health risks posed by the chemicals in air fresheners, there are also concerns about the secondary pollutants formed when these chemicals interact with the ozone in the air. Furthermore, air fresheners with flammable aerosol or automatic spray mechanisms pose a fire hazard and have been linked to unintentional injuries, including burns.
While the casual use of air fresheners may not cause significant health issues in generally healthy individuals, those with underlying allergies, asthma, or respiratory ailments may be more susceptible to adverse effects. It is recommended to limit the use of air fresheners, especially in close proximity to individuals with these conditions, and to prioritise proper ventilation and air circulation when using scented products.

Air fresheners can contain toxic chemicals, such as benzene and formaldehyde, which are carcinogens
Air fresheners are popular products used to improve the scent of indoor environments, such as homes, offices, and vehicles. While they are designed to create a pleasant indoor space, some air fresheners can contain toxic chemicals that may negatively impact human health and the environment.
One of the primary concerns regarding air fresheners is their potential to contain toxic chemicals, including benzene and formaldehyde. These chemicals are classified as carcinogens, known to have adverse effects on human health. Formaldehyde, in particular, has been detected at high levels in indoor air, especially when multiple scented products are used simultaneously. This can lead to increased exposure and potential health risks.
Benzene and formaldehyde are not the only toxic chemicals found in air fresheners. Studies have identified other harmful substances, such as volatile organic compounds (VOCs), toluene, m,p-xylene, phthalates, and secondary pollutants like acetaldehyde, acetone, and picric acid. These chemicals can be released into the air and absorbed by surrounding surfaces, leading to prolonged exposure even after the air freshener is no longer in use.
The potential health risks associated with exposure to these toxic chemicals include respiratory issues, migraine headaches, asthma attacks, mucosal symptoms, and infant illness. Additionally, people with underlying allergies or asthma may experience airway irritation and inflammation due to the chemicals released by air fresheners, even when used in normal amounts.
It is worth noting that not all air fresheners are created equal. While some may contain toxic chemicals, there are alternative options available, such as essential oils, VOC-free candles, incense, flowers, and herbs, which can provide a more natural and safer way to introduce fragrances into your home. It is recommended to prioritise proper ventilation and air filtration throughout the home, as fresh air remains the healthiest option.

Candles and air fresheners can cause indoor air quality issues by adding pollutants and chemicals to the air
Candles and air fresheners are popular items used to improve the scent of indoor spaces. However, their use can also lead to indoor air quality issues by releasing chemicals and pollutants into the air.
Candles, particularly scented candles, are known to release chemicals when burned. A 2014 study found that scented candles emit non-fragrance combustion chemicals such as benzene and formaldehyde, which are considered carcinogens. While the levels detected in the study were below the concentration limits set by the World Health Organization, the presence of these chemicals in indoor air still poses a potential health risk.
In addition to the chemicals released by scented candles, certain candle ingredients, such as paraffin wax and synthetic fragrances, can also release harmful pollutants when burned. These pollutants can contribute to poor indoor air quality and have negative health effects, especially for individuals with respiratory ailments, allergies, or asthma.
Air fresheners, which are designed to mask or neutralize unpleasant odours, can also contribute to indoor air quality issues. They often contain synthetic fragrances designed to mimic natural scents, and these fragrances can linger in the air for extended periods. Like candles, air fresheners can release chemicals into the air, including formaldehyde, which is a known carcinogen. The use of aerosol sprays as a dispersal method for air fresheners can further irritate the airways, particularly for individuals with allergies or asthma.
Overall, while candles and air fresheners can enhance the scent of indoor spaces, their use can also introduce chemicals and pollutants into the air, leading to potential health issues for susceptible individuals. To mitigate these risks, it is recommended to limit the use of scented candles and air fresheners, ensure proper ventilation, and opt for natural alternatives like essential oils or plants.

Some air fresheners may be unsafe for children, especially if they contain evaporating beads or reed diffuser solutions
While scented candles and air fresheners are popular items used by many families inside their homes, there are concerns about their potential harm. Some reports on the internet regarding this issue are exaggerated or misconstrued, but others are more accurate.
Air fresheners and scented candles contain a wide variety of different chemicals. Exposure to these chemicals, even in normal situations, can be irritating to the airways, particularly for people with underlying allergies or asthma. This is especially true for aerosol sprays, which use propellants and chemicals to disperse small particles into the air. These products contain volatile organic compounds (VOCs) and formaldehyde, which can be hazardous to health. Formaldehyde, for example, has been linked to cancer, headaches, and lung difficulties.
Evaporating beads and reed diffuser solutions pose a particular risk to children. They are dangerous because it is very easy to ingest large amounts of them. Evaporating beads are slippery and tiny, making them easy to swallow by a child. Plugin-style air fresheners usually have a top that easily screws off to expose a liquid that could be ingested as easily as taking a sip of a drink. The beads are also dangerous because they contain enough VOCs to cause serious effects, and they slowly dissolve in the intestine, causing a prolonged release of these toxic chemicals. Swallowing the gel-type evaporative beads can cause serious effects, including vomiting, drowsiness, tremors or seizures, stomach upset, and mouth irritation.
Reed diffusers also contain ingredients that can be harmful if swallowed, such as isopropyl alcohol (rubbing alcohol) and essential oils like lavender oil and eucalyptus oil. If swallowed, these can cause drowsiness, tremors or seizures, stomach upset, and mouth irritation. The slender sticks used in reed diffusers could also cause injury.
To ensure the safe use of reed diffusers, they should be placed in a location with excellent ventilation, away from heat sources, and out of children's and pets' reach. It is also important to follow the manufacturer's usage guidelines.
