Burning incense is a centuries-old practice with roots in religious and spiritual rituals, as well as in masking unwanted odours. However, the smoke and fumes released by incense are considered air pollution and can have negative health effects. The smoke contains particulate matter (PM), gaseous products, and organic compounds, which can cause respiratory issues and increase the risk of certain types of cancer. With this in mind, it is reasonable to consider that burning incense may cause air filters to become dirtier, resembling the effects of smoking.

Incense smoke contains particulate matter, gas products, and organic compounds
Incense burning is a common practice in many cultures and religions, such as Buddhism and Taoism, and is often used for spiritual or hygienic purposes. However, the smoke produced by burning incense contains particulate matter, gas products, and organic compounds that can have negative health effects.
The particulate matter in incense smoke includes small, inhalable particles that can be carcinogenic. These particles can enter the respiratory system and cause dysfunction. The size of the particles varies, with coarse particles being greater than 10 μm in diameter, while fine particles are in the 2.5 μm size range and below. The combustion of incense is a major source of residential indoor particulate matter, and it produces more particulates than cigarettes, with an average of 45 mg/g burned compared to 10 mg/g burned for cigarettes.
The gas products released from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and others. These gases can contribute to air pollution and have harmful effects on health. Incense burning is a significant indoor pollutant and can aggravate the risk of respiratory issues such as asthma and allergic rhinitis.
In addition to particulate matter and gas products, incense smoke also contains volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). These include benzene, toluene, xylenes, aldehydes, polycyclic aromatic hydrocarbons (PAHs), musk ketones, musk ambrette, diethylphthalate (DEP), and more. The organic compounds in incense smoke are toxic to the lungs and can cause allergic contact dermatitis, as well as being allergenic to the skin and eyes. They have also been associated with an increased risk of certain types of cancer, heart disease, and brain health issues in older adults.
While the specific health effects of each component in incense smoke are difficult to isolate, the complex mixture of pollutants has been shown to have detrimental impacts on human health. It is important for people who burn incense to be aware of these potential risks and take steps to reduce exposure and improve ventilation when using incense.

Burning incense is a significant indoor pollutant
Burning incense is a significant source of indoor air pollution, with adverse health effects. The smoke released from burning incense contains particulate matter (PM), including PM10 and PM2.5, which can be detrimental to respiratory health. The combustion of incense also produces gaseous products, such as carbon monoxide, isoprene, benzene, and volatile organic compounds (VOCs), which are known to be harmful.
Incense smoke has been associated with an increased risk of respiratory problems, including airway hyperresponsiveness, asthma, and allergic rhinitis. It can also cause respiratory system dysfunction, with effects on the bronchial epithelial barrier and oxidative stress. The particulate matter in incense smoke is inhalable and can have negative health outcomes, including potential carcinogenic effects. While the precise mechanisms are still under investigation, studies have found links between long-term incense burning and cognitive decline, particularly in older adults.
The impact of incense burning on indoor air pollution is especially notable in Taiwanese Buddhist and Taoist residents, who burn incense as part of their religious practices. Studies have shown that the accumulation of fine particulate matter (PM2.5) due to incense burning in Taiwanese temples and homes can be significantly higher than recommended air quality levels, leading to potential adverse health risks for occupants.
To mitigate the indoor air pollution caused by burning incense, it is essential to increase ventilation by opening windows during and after burning. Reducing exposure time and ensuring proper airflow can help decrease the concentration of contaminants and lower the associated health risks.

Incense smoke is associated with an increased risk of heart disease, cancer, and asthma
Incense smoke contains particulate matter, including carcinogens and irritants, that can be easily inhaled and may lead to respiratory diseases such as asthma. The particulate matter in incense smoke has been found to be mutagenic in the Ames Salmonella test with TA98 and activation. It has also been associated with neoplasm.
Burning incense produces more particulates than cigarettes, with an average of 45 mg/g burned compared to 10 mg/g burned for cigarettes. The combustion of incense also generates hazardous volatile organic compounds (VOCs) such as benzene, toluene, xylenes, and isoprene, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These compounds are known to cause acute symptoms such as eye irritation, nose irritation, throat irritation, headaches, nausea/vomiting, dizziness, and asthma exacerbation. Chronic exposure to these compounds can lead to cancer, liver damage, kidney damage, and central nervous system damage.
The smoke released from burning incense has a sweet, pleasant smell, but it can be a significant source of indoor air pollution and is considered comparable to or even more harmful than passive smoking. Studies have found a positive correlation between incense smoke exposure and the increased risk of numerous health issues, including respiratory problems, cardiovascular diseases, and cancer.
In addition to the respiratory and cardiovascular risks, incense smoke has also been associated with an increased risk of heart disease and issues with brain health in older adults. A 2020 study found that long-term exposure to incense smoke may cause cognitive performance delays and decreased brain connectivity in community older adults over 65 years of age.
While the direct causal relationship between incense burning and these diseases has not been established, the correlation and potential health risks are significant enough to warrant caution and further research.

Incense smoke may cause issues with brain health in older adults
Burning incense emits smoke, which contains natural and unnatural ingredients that create small, inhalable particulate matter. These particles can cause respiratory system dysfunction and have been indicated to cause allergic contact dermatitis. A 2021 study also confirmed that some of these particles were carcinogenic, meaning they could cause cancer.
In addition to the particulate matter, incense smoke also contains gaseous products, including carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen dioxide, and volatile organic compounds. These gases can have negative health effects when inhaled, especially in indoor environments where ventilation is limited.
While the specific mechanisms are still being investigated, recent studies have found that incense burning may cause issues with brain health in older adults. A 2020 study by Wong et al. specifically looked at the impact of indoor incense burning on community older adults and found that it impacted cognitive functions and brain functional connectivity. The study suggested that this could be due to long-term air pollution caused by burning incense, resulting in smaller brain and prefrontal cortex volumes.
Another study by Lee et al. in 2021 also found that incense smoke induced oxidative stress and inflammation, which can lead to vascular dysfunction. This was supported by an earlier study in 2018, which assessed the long-term household incense smoke exposure of Thai-Vietnamese subjects and found it to be a risk factor for cardiovascular disease.
Overall, while the direct link between incense burning and cognitive and brain health issues needs further investigation, the current research suggests that incense smoke may indeed cause issues with brain health in older adults, especially those who have been exposed to it for many decades.
