Incense smoke may be carcinogenic
Burning incense is a popular way to add fragrance to homes and has been used for hygienic, spiritual, and religious purposes for centuries. However, recent studies have suggested that incense smoke may be carcinogenic and could cause cancer.
Incense smoke contains particulate matter (PM), gas products, and organic compounds. On average, incense burning produces more particulates than cigarettes, with an average of 45 mg/g compared to 10 mg/g for cigarettes. The gas products from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and sulfur dioxide (SO2). In addition, incense burning produces volatile organic compounds such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons. These compounds can be toxic and have adverse effects on human health.
A 2021 study confirmed that some of the particulate matter in incense smoke was carcinogenic. There is also an association between higher cancer risk and incense use. The toxicities of incense smoke come directly from its harmful constituents and deposition capacity in the body. In addition, the oxidative stress and inflammation caused by incense smoke may also contribute to its carcinogenic effects.
It is important to note that the specific mechanisms by which incense burning causes these health issues are still not fully understood and further research is needed, especially on humans. However, the current evidence suggests that prolonged inhalation of incense smoke may be harmful and could increase the risk of cancer. As such, it is advisable to reduce exposure time when in places with heavy incense smoke and to ventilate rooms when burning incense at home.

Incense smoke is an air pollutant
Incense burning has been a traditional practice in many parts of the world, especially in the Eastern regions, for various purposes since ancient times. In Asian countries where Buddhism and Taoism are mainstream religions, such as China, Thailand, and Taiwan, burning incense is a daily practice. However, incense smoke released during the burning process contains particulate matter (PM), gas products, and many organic compounds, making it an air pollutant.
The smoke released from burning incense has a sweet, pleasant smell. However, it can also contain particulate matter that can be easily inhaled and potentially lead to negative health outcomes. The particulate matter from incense smoke has been found to be mutagenic in tests, and there is a documented association between incense smoke and respiratory system dysfunction. In addition, incense smoke has been linked to an increased risk of respiratory problems, including childhood asthma and the development of respiratory allergies.
The gas products from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and sulfur dioxide (SO2). Incense burning also produces volatile organic compounds (VOCs) such as benzene, toluene, and xylenes, which are known to have adverse effects on human health. These compounds can contribute to indoor and outdoor air pollution, especially in densely populated areas where incense burning is a common practice.
Furthermore, recent research has suggested that incense smoke may have overlooked health dangers. Studies have found associations between incense burning and an increased risk of cancer, asthma, and heart disease. However, it is important to note that these studies have primarily been conducted on animals, and further research on humans is necessary to confirm these findings. Additionally, the specific mechanisms by which incense smoke may cause these health issues require further investigation.

Incense is made from flammable materials
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 forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing uses. Incense can be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Direct-burning incense, or "combustible incense", is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance.
Incense sticks are made of highly flammable materials. If one were to tip over, it could easily start a fire. The combustible base of a direct-burning incense mixture binds the fragrant material together and allows the incense to burn with a self-sustained ember, which propagates slowly and evenly through the entire piece of incense. Commercially, two types of incense base predominate: fuel and oxidizer mixtures. Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base before or after shaping, depending on whether they are in powder form or essential oils.
A typical composition of stick incense consists of 21% (by weight) of herbal and wood powder, 35% of fragrance material, 11% of adhesive powder, and 33% of bamboo stick. Incense smoke contains particulate matter, gas products, and many organic compounds. On average, incense burning produces more particulates than cigarettes. The gas products from burning incense include CO, CO2, NO2, and SO2. Incense burning also produces volatile organic compounds, such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs).
Burning incense may trigger asthma and has been associated with an increased risk of respiratory allergies, heart disease, and cancer. Studies suggest that incense smoke can also trigger chronic inflammation in the body. However, further research is necessary on humans, as many studies have only been conducted on rats.

Incense smoke may cause inflammation
Burning incense is a traditional practice in many parts of the world, especially in Asia, for various purposes, including religious rituals, aromatherapy, and meditation. While it is known for its fragrant smoke and ability to enhance the scent of indoor areas, recent studies have highlighted potential health risks associated with inhaling incense smoke.
Incense smoke contains particulate matter, which refers to small particles that can be easily inhaled and can have negative health outcomes. These particles are a mixture of solid and liquid droplets that can enter the respiratory system and cause harm. The particulate matter in incense smoke has been found to be greater than 45 mg/g burned, which is significantly higher than the amount produced by cigarettes, which is around 10 mg/g burned.
The gas products released from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and volatile organic compounds such as benzene, toluene, and xylenes. These gases can contribute to indoor and outdoor air pollution and have adverse effects on human health.
One of the potential health risks associated with incense smoke is the development of chronic inflammation in the body. This inflammation is caused by the body's response to processing particulate matter into metabolites, which also leads to oxidative stress. The reactive oxygen species-driven oxidative stress and associated inflammation are believed to be underlying mechanisms for various unfavorable health responses. However, it is important to note that further research is needed to fully understand the impact of incense smoke on human health.
The health risks associated with incense smoke exposure include respiratory problems, an increased risk of asthma and other respiratory allergies, and a potential link to cancer. Additionally, there may be issues with brain health in older adults, including delays in cognitive performance and decreased brain connectivity. However, it is important to note that the studies showing these associations do not necessarily prove causation, and further research is required to establish direct links between incense smoke and specific health conditions.
