What You'll Learn
Burning incense and cancer risk
Burning incense is a popular practice across the world, especially in the Eastern regions, for various purposes, including religious and spiritual reasons, meditation, aromatherapy, and deodorising. However, recent studies have suggested that burning incense may have negative health effects and could be linked to cancer.
A 2021 study confirmed the presence of carcinogens in the particulate matter released from burning incense. The particulate matter, which is easily inhalable, contains toxic and irritant compounds alongside aromatic compounds. These toxic compounds include polyaromatic hydrocarbons (PAHs), carbonyls, and benzene. PAHs are produced by burning any organic material, including tobacco leaves, coal, or incense sticks.
Several studies have found an association between long-term incense use and an increased risk of developing squamous cell carcinomas of the respiratory tract. The influence of incense on the risk of cancer was found to be dependent on the histological subtype, with the most pronounced effects observed for carcinomas of the upper respiratory tract. This is consistent with studies showing that particulate matter from incense burning predominantly deposits in the upper airways.
However, it is important to note that the link between incense burning and cancer is not yet fully understood. Some studies have found conflicting results, with certain research showing no overall effect of incense use on lung cancer. Furthermore, the largest study to date, tracking the health of 61,000 people in Singapore, concluded that incense use is generally safe in normal amounts, and the risk of cancer is very small, if at all.
While the potential health risks associated with incense burning cannot be ignored, more research is needed to fully understand the mechanisms and implications of incense smoke on human health.

Incense smoke and respiratory issues
Burning incense is a popular practice across the world, with a long history in many cultures and religions. However, recent research has revealed that there could be some health drawbacks to this practice.
Incense smoke contains various irritants and toxic compounds, which can be easily inhaled and may lead to respiratory issues. These include respiratory allergies, asthma, and other respiratory diseases. A study in 2021 confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could cause cancer. This is supported by the fact that most cancers associated with incense use are upper respiratory tract carcinomas or lung carcinomas.
Burning incense has also been linked to an increased risk of hospital admissions, morbidity, and mortality, mainly due to respiratory problems. The smallest particles in incense smoke, known as ultrafine particles, are thought to be particularly harmful in this regard.
Furthermore, incense smoke can trigger chronic inflammation in the body, which stems from the body processing particulate matter into metabolites, causing oxidative stress. This can lead to an increased risk of cardiovascular diseases and even cancer.
While the precise mechanisms behind these health issues are still being studied, it is clear that burning incense may pose health risks, particularly to those with pre-existing respiratory conditions. As such, it is important to be cautious and consider alternative ways to freshen indoor spaces or achieve spiritual purposes.

Incense as an air pollutant
Burning incense is a traditional practice in many parts of the world, especially in the Eastern regions, for various purposes, including religious rituals, aromatherapy, and meditation. However, recent studies have raised concerns about the potential health risks associated with incense smoke, suggesting that it may contribute to indoor air pollution and have negative health consequences.
The smoke released from burning incense contains particulate matter, including ultrafine particles, that can be easily inhaled and lead to respiratory issues. These particles are small enough to enter our bloodstream and organs, potentially causing long-term harm. The frequency and duration of incense burning directly impact the concentration of pollutants, with higher exposure leading to increased risks. The smoke also contains volatile organic compounds (VOCs), such as benzene, formaldehyde, acetaldehyde, and acrolein, which have been linked to severe health effects, including carcinogenic, mutagenic, and reprotoxic impacts.
The incomplete combustion of incense results in the emission of harmful constituents, including toxicants and irritants, which can cause oxidative stress and inflammation in the body. This inflammation is caused by the body's processing of particulate matter, leading to potential respiratory conditions, cardiovascular issues, and even an increased risk of cancer. While some studies suggest a correlation between incense use and cancer, it is important to note that the direct causation has not been conclusively established.
To mitigate the potential health risks associated with incense burning, it is recommended to reduce the burning time, frequency, and quantity of incense used. Additionally, improving ventilation and using air purifiers with HEPA filters and carbon filters can help reduce the concentration of pollutants and dangerous gases released from incense burning.
While incense burning has cultural and religious significance, it is important to be aware of the potential health risks and take appropriate measures to ensure safe use. Further research is also necessary to fully understand the mechanisms and implications of incense burning on human health.

Incense and brain health
Burning incense is a common practice in many parts of the world, especially in the East, for various purposes, including religious and spiritual rituals, meditation, aromatherapy, and deodorizing. While it is known for its pleasant fragrance, recent studies have highlighted certain health risks associated with incense burning, particularly concerning cognitive functions and brain health.
Several studies have indicated that burning incense releases pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), volatile organic compounds, aldehydes, and polycyclic aromatic hydrocarbons (PAHs). These pollutants contribute to indoor air pollution, with the amount of PM generated by incense being up to 4.5 times higher than that produced by cigarettes. While the specific mechanisms require further investigation, the pollutants emitted from incense smoke have been linked to potential adverse effects on cognitive functions and brain health.
One study found that incense burning was associated with poorer cognitive performance over three years, decreased brain connectivity, and an interaction with vascular disease, which further predisposed individuals to poor cognitive performance. Another study reported that incense smoke could induce oxidative stress and inflammation, leading to reduced vascular nitric oxide levels and increased levels of inflammatory mediators, resulting in vascular dysfunction. These changes can have detrimental effects on brain health and cognitive function.
It is important to note that the type of incense and the presence of adequate ventilation play crucial roles in mitigating the potential risks associated with incense burning. Japanese-style incense, for example, is known to release fewer particulates compared to other types. Additionally, ensuring proper ventilation and avoiding inhaling smoke directly can help minimize the potential negative impacts on brain health.
While the research suggests correlations between incense burning and cognitive decline, it is important to consider other factors that may contribute to these findings. For instance, lower education, socioeconomic status, or a sedentary lifestyle could be potential confounders in the relationship between incense burning and cognitive function. Further research is needed to establish causal relationships and fully understand the impact of incense burning on brain health.

Incense and viruses
Burning incense has been a traditional practice in many parts of the world, especially in the East, for various purposes since ancient times. It has been used for hygienic, spiritual, and religious reasons. For example, in Asian countries where Buddhism and Taoism are mainstream religions, burning incense is a daily practice.
However, recent studies have revealed that burning incense may have negative health effects. The smoke released from burning incense contains particulate matter, which can be easily inhaled and may lead to respiratory issues. The particulate matter in incense smoke contains carcinogens and irritants, which have been linked to an increased risk of respiratory cancers and asthma. Burning incense has also been associated with an increased risk of heart disease and a 2020 study found that it may cause issues with brain health in older adults.
In addition, burning incense has been found to increase the levels of volatile organic compounds (VOCs) in the air, such as benzene and formaldehyde, which are associated with a host of health problems. A 2020 study also found that burning incense indoors can facilitate the transmission of the SARS-CoV-2 virus by releasing coarse and fine particles into the air.
While some studies have shown that burning certain botanicals, such as sage, can have antiviral properties, there is no evidence that burning incense will kill viruses. In fact, burning incense may increase the transmission of viruses due to the release of particulate matter into the air. Therefore, it is important to rely on scientifically researched practices, such as hand washing and proper cleaning, to prevent the spread of viruses.
