Incense smoke contains particulate matter, gas products, and organic compounds
Incense is an aromatic biotic material that releases fragrant smoke when burnt. It is composed of aromatic plant materials, often combined with essential oils. The smoke released from burning incense contains particulate matter, gas products, and organic compounds.
The particulate matter in incense smoke is made up of fine particles, with sizes ranging from 10 to 500 nanometres. These particles can be inhaled and contribute to indoor air pollution, especially in enclosed spaces with poor ventilation. The combustion of incense is a major source of residential indoor particulate matter, and it produces significantly more particulate matter than the combustion of cigarettes.
The gas products released from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and other nitrogen and sulfur oxides. These gases can have harmful effects on respiratory health when inhaled, causing respiratory system dysfunction and potentially contributing to airway diseases.
In addition to particulate matter and gas products, incense smoke also contains volatile organic compounds (VOCs) such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These organic compounds are adsorbed onto the particulate matter, and their health effects can be challenging to isolate from those of the gaseous and particulate components. However, exposure to incense smoke has been associated with allergic contact dermatitis, elevated cord blood IgE levels, and potential mutagenic effects.
While incense has been traditionally used for aesthetic, religious, and ceremonial purposes, it is important to be aware of the potential health implications of inhaling the complex mixture of particulate matter, gas products, and organic compounds released during burning.

Burning incense can reduce bacterial counts and purify the air
Burning incense is a common practice in many cultures, often associated with religious ceremonies, spiritual practices, and aromatherapy. While it is believed to have various benefits, such as improving air quality and enhancing wellbeing, there are also concerns about its potential impact on health and indoor air pollution.
Several studies have demonstrated the antibacterial properties of incense. One notable study found that exposing aerial bacterial populations to incense smoke for just one hour resulted in a significant reduction of over 94% in bacterial counts. This purification effect persisted for up to 24 hours in a closed room, and the absence of pathogenic bacteria was observed even after 30 days. These findings suggest that burning incense can effectively eliminate harmful bacteria from the air within confined spaces.
The antibacterial effects of incense can be attributed to the release of certain organic compounds during burning. Incense smoke typically contains particulate matter, gas products, and organic compounds such as benzene, toluene, and xylenes. While these compounds can have antibacterial benefits, they may also contribute to indoor air pollution if not properly ventilated.
It is important to distinguish between high-quality and low-quality incense. Poor-quality incense, especially when burned indoors or in small spaces, can release toxic substances and act as a pollutant. Long-term exposure to such incense smoke can be harmful to the lungs and respiratory system. Therefore, it is recommended to use non-toxic, natural, and high-quality incense to ensure a pleasant and safe experience.
To mitigate the potential impact of incense smoke, some individuals opt for additional measures such as using air purifiers or handheld smoke filters. These devices can help capture and eliminate smoke and odours, improving indoor air quality and reducing the potential harm associated with incense burning.

Incense smoke may contain carcinogens and other harmful compounds
Incense smoke contains particulate matter, which can be easily inhaled and may have negative health outcomes. A 2021 study confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could cause cancer. In addition, incense smoke has been associated with an increased risk of heart disease and asthma.
The particulate matter in incense smoke contains toxic and irritant compounds, including volatile organic compounds (VOCs), carbonyls, aldehydes, and polycyclic aromatic hydrocarbons (PAHs). These compounds are typically characterized by their irritating properties. Exposure to formaldehyde, for example, a probable human carcinogen, can cause a burning sensation, bronchial constriction, choking, and coughing.
Diethylphthalate (DEP), a suspect carcinogen, is used extensively in the incense stick industry as a binder of perfumes. It can be emitted into the air during incense burning. A study by Sonde et al. found significantly altered lipid and enzyme levels in the liver and serum of rats fed with DEP.
The effects of incense smoke on health are difficult to study directly, and further research on humans is needed. However, several epidemiological studies have suggested that incense smoke causes health problems, particularly respiratory dysfunction.

Low-quality incense can be a pollutant and cause lung issues
Burning low-quality incense can be harmful to your health. Poor-quality incense is a pollutant, especially if burned indoors or in small spaces. It can cause lung issues if inhaled over a long period. To avoid this, opt for high-quality, non-toxic incense.
The smoke released from incense contains particulate matter, which can be easily inhaled and may lead to negative health outcomes. A 2021 study found that some of these particles were carcinogenic, and an association has been found between incense use and a higher risk of certain cancers, particularly of the upper respiratory tract and lungs. The smoke from incense also contains toxic and irritant compounds, which can cause respiratory issues such as asthma and other allergies.
In addition, incense smoke has been linked to morphological changes in alveolar pneumocytes and infiltration of neutrophils into alveolar lumena in experimental rats. This activation of inflammatory cells can lead to airway inflammation and remodeling, which may be pivotal to asthma pathogenesis.
The practice of burning incense is a popular cultural practice in many parts of the world, with incense burned daily in Asian countries where Buddhism and Taoism are mainstream religions. A typical composition of stick incense consists of herbal and wood powder, fragrance material, adhesive powder, and a bamboo stick. However, incense makers often add more materials to enhance their fragrance, ability to burn, and ability to hold their shape.
The smoke generated from burning incense contains pollutants that may cause inflammation in human lung cells. These pollutants include carbon monoxide, sulfur dioxide, oxides of nitrogen, and formaldehyde, which are similar to those found in cigarette smoke. Charcoal briquettes, often used to ignite and burn incense, add to the harmful levels of carbon monoxide and other pollutants.
While incense has been used for thousands of years with many reported benefits, recent research highlights potential health dangers, particularly from long-term exposure to indoor air pollution caused by incense burning.
