Incense smoke contains particulate matter, which can cause respiratory issues
Particulate matter in incense smoke can be classified as coarse particles or fine particles. Coarse particles are larger than 10 μm in diameter and do not enter the respiratory system, while fine particles, or PM10, are smaller than 10 μm and can accumulate in the respiratory system, causing potential harm. The gaseous phase of incense smoke consists of carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen dioxide, formaldehyde, polycyclic aromatic compounds, and volatile organic compounds. The organic compounds produced by burning incense include benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs).
These PAHs have been linked to cancer, and a 2021 study confirmed the presence of carcinogenic particulate matter in incense smoke. However, it is important to note that the largest study on incense use and cancer found that incense burning in normal amounts does not significantly increase the risk of cancer. Nevertheless, incense smoke has also been associated with an increased risk of heart disease and chronic inflammation in the body.
The effects of incense smoke exposure are not limited to respiratory issues. A 2020 study found that incense burning may negatively impact brain health in older adults, leading to delays in cognitive performance and decreased brain connectivity. Additionally, people working in temples, where incense burning is a daily practice, have a higher chance of developing throat and nose irritation compared to those working in churches. A cross-sectional study in China also linked incense burning to weekly symptoms in the eyes, throat, and skin.
Overall, while incense burning may have cultural, spiritual, and hygienic significance in many parts of the world, it is important to be aware of the potential health risks associated with inhaling incense smoke, particularly the respiratory issues that may arise from exposure to particulate matter.

It may also contain carcinogens, increasing the risk of cancer
Incense smoke contains particulate matter, which includes small particles that can be inhaled. A 2021 study confirmed that some of these particles are carcinogenic, suggesting that exposure to incense smoke could increase the risk of cancer.
The study found that incense smoke contains polycyclic aromatic hydrocarbons (PAHs), which have been linked to cancer. PAHs are produced by the incomplete combustion of organic materials, such as tobacco leaves, coal, or incense sticks. While the largest study on incense use and cancer concluded that the risk of cancer is very small, it did find a link between burning incense indoors and increased levels of PAHs.
In addition to the potential carcinogenic effects, incense smoke has been associated with an increased risk of respiratory problems, cardiovascular disease, and adverse effects on brain health. Multiple epidemiological studies have indicated the negative impact of incense burning on lung function, with exposure to incense smoke being linked to an increased risk of bronchitis, bronchiolitis, pneumonia, and wheezing.
Furthermore, a 2020 study found that long-term exposure to incense smoke may cause issues with brain health in older adults, including delays in cognitive performance and decreased brain connectivity. The study suggested that the air pollution caused by incense burning could lead to smaller brain and prefrontal cortex volumes.
It is important to note that the effects of incense smoke inhalation may depend on the type of incense and the amount of exposure. Some types of incense may contain higher levels of carcinogens or other harmful substances, and frequent or prolonged exposure to incense smoke could potentially increase the risk of developing health issues.

Burning incense produces air pollutants, which can cause indoor air pollution
Burning incense is a popular practice worldwide, with many cultures burning it for hygienic, spiritual, and health purposes. However, burning incense produces air pollutants, which can cause indoor air pollution and have harmful effects on health when inhaled.
Incense smoke contains particulate matter, including coarse particles greater than 10 μm in diameter and finer particles less than 10 μm in diameter (PM10). While the coarse particles are too large to enter the human respiratory system, the finer particles can accumulate in the respiratory system, causing respiratory dysfunction and irritation. In a prospective cohort study among school children in Hong Kong, exposure to incense burning was associated with increased risks of bronchitis, bronchiolitis, pneumonia, and wheezing. Similarly, a Taiwanese birth cohort study found that regular incense burning was the most critical risk factor among housing characteristics affecting health.
The gaseous phase of incense smoke includes carbon dioxide, carbon monoxide, sulfur dioxide, formaldehyde, nitrogen dioxide, and volatile organic compounds such as benzene, toluene, and xylenes. These gases contribute to indoor air pollution and can have harmful effects on human health. In addition, incense smoke releases polycyclic aromatic compounds and polycyclic aromatic hydrocarbons (PAHs), which have been linked to an increased risk of cancer. A 2021 study confirmed the presence of carcinogenic particulate matter in incense smoke, and multiple studies have found an association between incense use and a higher risk of cancer.
Furthermore, incense smoke has been associated with an increased risk of heart disease and potential issues with brain health in older adults. A 2020 study suggested that long-term exposure to incense smoke pollution could lead to smaller brain and prefrontal cortex volumes, resulting in delays in cognitive performance and decreased brain connectivity. However, more research is needed to fully understand the mechanisms behind these associations.
While the health risks associated with incense burning are concerning, it is important to note that the largest study on incense use and cancer, which tracked 61,000 people in Singapore, found that incense use is safe in normal amounts, and the risk of cancer is very small, if at all. Nonetheless, it is advisable to take precautions when burning incense, such as ensuring adequate ventilation and avoiding direct inhalation of the smoke, to minimize potential health risks.

Inhaling incense smoke can trigger chronic inflammation in the body
Incense is a smoke-emitting substance that is burned for hygienic, spiritual, and health purposes. It is a popular practice worldwide, with many different types of incense commercially available, including sticks, cones, coils, powders, and charcoal.
When incense is burned, it emits smoke containing particulate matter, gas products, and organic compounds. The particulate matter in incense smoke has been found to be carcinogenic, and there is an association between higher cancer risk and incense use. In addition, incense smoke has been linked to an increased risk of respiratory problems, cardiovascular disease, and even cancer.
Furthermore, studies suggest that incense smoke can trigger chronic inflammation in the body. This inflammation is caused by the body processing particulate matter into metabolites, which also leads to oxidative stress. Incense smoke has also been associated with an increased risk of heart disease and issues with brain health in older adults.
The organic compounds found in incense smoke include volatile organic compounds (VOCs) such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These compounds are known to have harmful effects on health and can be absorbed into the body through inhalation. While the precise mechanisms behind the health effects of incense smoke are still being studied, it is clear that inhaling incense smoke can have negative consequences on the human body.
