Incense smoke contains carcinogens and increases the risk of cancer
Incense smoke contains a multitude of carcinogens, including polycyclic aromatic hydrocarbons (PAHs), benzene, and carbonyls. These chemicals can cause mutations to DNA in human cells, leading to an increased risk of developing certain types of cancer, particularly those of the upper respiratory tract and lung.
A 12-year study published in the journal Cancer found that incense smoke contains cancer-causing chemicals, backing up previous research in this area. The study also noted that incense is often burned in enclosed spaces, leading to high levels of exposure to these carcinogens. Another study of 61,320 Singapore Chinese individuals who were cancer-free and aged 45-74 years found a link between long-term incense use and the development of squamous cell carcinomas of the respiratory tract.
Furthermore, the particulate matter in incense smoke can lead to respiratory diseases such as asthma and chronic inflammation in the body. It can also affect heart tissues and contribute to overall inflammation. A 2020 study also found that burning incense may negatively impact brain health in older adults over the age of 65.
While the carcinogenic properties of incense smoke are well-established, it is important to note that the precise mechanisms by which it affects human health are still being studied. Some studies have found no association between incense use and cancer development. However, given the high prevalence of incense use and the often involuntary nature of exposure, further research is necessary to clarify the role of incense smoke as a carcinogen and to establish safe usage guidelines.
To reduce potential health risks associated with incense use, it is recommended to limit exposure to the smoke, ensure proper ventilation during and after use, and explore alternative products such as electronic incense that do not produce smoke or aromatic simulation without the presence of smoke.

Burning incense may cause issues with brain health and cognitive performance
Burning incense has been linked to a variety of health issues, including respiratory problems, asthma, and cancer. Recent studies have also suggested that it may negatively impact brain health and cognitive performance, particularly in older adults.
A 2020 study found that long-term exposure to incense smoke was associated with reduced brain health in community-dwelling older adults over the age of 65. The study found that the fine particulate matter and air pollution caused by incense burning may lead to reduced brain and prefrontal cortex volumes, resulting in delays in cognitive performance and decreased brain connectivity.
While the precise mechanisms behind these associations remain unclear, the study highlights the potential risks of incense burning on brain health and cognitive function, particularly in the elderly. It is important to note that the study only found an association between incense burning and brain health issues, rather than a causal relationship. However, it adds to a growing body of evidence suggesting that incense smoke can have multiple adverse health effects.
The smoke released from burning incense contains particulate matter, volatile organic compounds, and chemical compounds that are small enough to inhale and can reach the deep lung tissues and even the bloodstream. These particles can cause respiratory problems, lung inflammation, and an increased risk of cancer, particularly in the upper respiratory tract and lungs.
To reduce the potential health risks associated with incense burning, it is recommended to keep the room well-ventilated and ensure proper air circulation to dilute indoor air pollutants. Additionally, electronic incense products are available as a safer alternative to traditional incense burning, offering visual and aromatic simulations without the presence of smoke.

Incense smoke is a source of indoor air pollutants and can cause respiratory problems
Incense is a smoke-emitting substance made from wood, resins, powders, and other natural materials. It has been used for centuries as part of religious ceremonies and for hygienic and spiritual purposes. However, the smoke released from burning incense contains particulate matter that can be easily inhaled and may have negative health outcomes.
The effects of incense smoke on health are becoming increasingly recognised, with a growing body of evidence reporting negative impacts on human well-being. For example, a 2020 study found that burning incense may cause issues with brain health in older adults over 65 years of age, including delays in cognitive performance and decreased brain connectivity. This may be due to long-term air pollution caused by incense burning.
To reduce the risk of exposure to indoor air pollutants from incense smoke, it is recommended to keep the room well-ventilated when burning incense. This will help to dilute the pollutants and reduce the potential health risks. Additionally, electronic incense products are available as an alternative to traditional incense burning, providing a way to experience the same religious or spiritual practices without the associated health risks.

Incense smoke may affect heart tissues and cause inflammation in the body
Incense burning is a common practice in many parts of the world, with various cultural and spiritual significance. However, recent inquiries have been made into the potential negative health impacts of incense smoke.
Incense smoke contains particulate matter, gases such as carbon monoxide, and volatile organic compounds. The particulate matter in incense smoke can be inhaled and may contain carcinogens and irritants, which have been associated with an increased risk of respiratory diseases, including asthma and even cancer.
Furthermore, incense smoke has been linked to an increased risk of heart disease. Studies have found that exposure to incense smoke can affect heart tissues and cause inflammation in the body. In vivo experiments have shown that incense smoke exposure may result in oxidative stress in rat heart tissues, leading to an increase in interleukin 6 (IL-6) and a decrease in NO synthesis. IL-6 plays a central role in the pathophysiology of cardiovascular diseases, and the dysfunction of endothelium due to decreased NO can lead to vascular issues and mortality.
Additionally, a 2020 study found that long-term exposure to incense smoke may negatively impact brain health in older adults, causing delays in cognitive performance and decreased brain connectivity.
While the underlying mechanisms of these health effects are still being studied, the current evidence suggests that incense smoke can have adverse effects on human health, particularly in the heart and respiratory system. It is important to note that the impact of incense smoke may vary depending on the type of incense and the duration and concentration of exposure. Reducing incense use and ensuring proper ventilation during and after burning incense can help lower the potential health risks.
