Incense smoke may cause respiratory issues
Incense is a smoke-emitting substance that has been burned for centuries for various purposes, including religious, hygienic, and spiritual reasons. While it is a popular practice, recent research has revealed potential health drawbacks associated with incense burning.
One of the main concerns is the impact of incense smoke on respiratory health. The smoke released during the burning process contains particulate matter, including microscopic particles that can be inhaled. These particles can enter the respiratory system and cause dysfunction. Incense smoke has been linked to respiratory problems, with evidence suggesting it may be even more harmful than passive smoking. It can also cause allergic contact dermatitis and has been associated with neoplasm.
The composition of incense varies, but it typically includes herbal and wood powder, fragrance material, adhesive powder, and a bamboo stick. However, some incense contains natural and unnatural ingredients, such as resins, which are known lung irritants and carcinogens. The emission of smoke and its harmful constituents, including volatile organic compounds, can lead to indoor and outdoor air pollution, contributing to respiratory issues.
To reduce the potential risks associated with incense burning, it is recommended to limit exposure and improve ventilation. Opening windows during or after burning incense can help reduce exposure to smoke. Additionally, exploring alternatives to incense or opting for safer types of incense with natural ingredients can be considered.
While the impact of incense smoke on respiratory health is a concern, more research is needed to fully understand the underlying mechanisms and the specific types of incense that pose the greatest risks. It is also important to note that the level of risk may depend on the volume of smoke and the frequency of exposure.

Burning incense is linked to air pollution
Burning incense is a popular practice across the world, with a global consumption exceeding 200 million tons per year. It is a religious ritual commonly practised in many cultures, especially in Asia, where it is a daily practice in Buddhism, Taoism, and Hinduism. Incense is also burnt for hygienic, spiritual, and aromatherapy purposes.
However, burning incense is considered a major source of indoor air pollution. The smoke released during the burning process contains particulate matter (PM), gas products, and many organic compounds. On average, incense burning produces more particulates per gram burned compared to cigarettes. 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, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs).
The frequency and duration of incense burning, as well as the quantity of products used, directly impact the concentration of pollutants in the air. Higher concentrations of these pollutants can have harmful effects on health. Studies have found associations between exposure to incense smoke and increased risks of respiratory problems, cardiovascular diseases, and even cancer. Additionally, long-term exposure to incense smoke has been linked to cognitive issues and changes in brain functionality in older adults.
To reduce exposure to incense smoke, it is recommended to limit the burning time, burn it as infrequently as possible, and improve ventilation in the space by opening windows.

Incense can contain carcinogens
Incense burning has been a traditional practice in many parts of the world, especially in the East, for various purposes since ancient times. It is an integral part of daily life in large parts of Asia and is used in places of worship and at home. The incense used in Asian countries is made of plant material mixed with essential oils, forming a combustible mixture that releases fragrant smoke when burned.
However, incense smoke contains a multitude of harmful constituents, including polycyclic aromatic hydrocarbons (PAHs), benzene, and carbonyls, which are known carcinogens. These harmful constituents are released into the air during the burning process and can be inhaled into the human body. The particulate matter in incense smoke contains carcinogens and irritants, which could lead to respiratory diseases such as asthma. In fact, a 2021 study confirmed that some of the particulate matter in incense smoke was carcinogenic, meaning it could cause cancer.
The burning of incense has also been linked to increased levels of chemicals called polycyclic aromatic hydrocarbons (PAHs), which have been associated with cancer. While the carcinogenic properties of incense smoke are well-established, no epidemiological studies have established a direct link between incense use and an increased risk of cancer in the respiratory tract. However, there is growing evidence of an association between exposure to incense smoke and an increased risk of various health issues, such as respiratory problems, cardiovascular diseases, and even cancer.
To reduce potential health risks, it is recommended to limit incense use and exposure to its smoke. Opening windows during or after burning incense can help reduce exposure. Additionally, exploring alternatives to incense is an option for those concerned about the potential risks.

Incense burning has been a traditional practice in many parts of the world, especially in the Eastern regions, for various purposes since ancient times. It is an indispensable ritualistic practice in some religions, such as Buddhism, Taoism, and Hinduism. In Asian countries where Buddhism and Taoism are the mainstream religions, such as China, Thailand, and Taiwan, burning incense is a daily practice.
However, recent studies have shown that inhaling incense smoke is comparable to passive smoking and may have adverse effects on human health. Incense smoke contains particulate matter (PM), gas products, and many organic compounds. On average, incense burning produces more particulates than cigarettes, with 45 mg/g burned compared to 10 mg/g burned for cigarettes. The gas products from burning incense include CO, CO2, NO2, SO2, and others. Incense burning also produces volatile organic compounds, such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These chemicals have been linked to an increased risk of numerous health issues, including respiratory problems, cardiovascular diseases, and even cancer.
The toxicities of incense smoke come directly from its harmful constituents and deposition capacity in the body. Incense smoke can cause respiratory system dysfunction and has been associated with neoplasm and allergic contact dermatitis. It is considered a major source of both outdoor and indoor air pollution, contributing to the pervasive use of incense in modern societies.
To reduce the potential health risks associated with incense burning, it is recommended to limit incense use and exposure to the smoke. Opening windows during or after use can help reduce exposure, and exploring alternatives to incense is also an option for those concerned about the risks. While some studies suggest that incense use is safe in normal amounts, with a very small risk of cancer, if any, it is important to note that the precise mechanisms of the adverse effects of incense burning are still being investigated.
