Incense smoke contains carcinogens and irritants, which can lead to respiratory diseases
Incense is a smoke-emitting substance, and like anything else that emits smoke, it can be accidentally inhaled. Incense smoke contains particulate matter, which can be easily inhaled and may have negative health outcomes. The particulate matter in incense smoke contains carcinogens and irritants, which can lead to respiratory diseases.
A 2008 study of adults in Singapore found a long-term association between burning incense and an increased risk of developing squamous cell lung cancer. Similarly, a 1966 study by Sturton et al. reported a high incidence of nasopharyngeal carcinoma in Hong Kong in male patients who burn incense. They found that 74.5% of the studied nasopharyngeal cancer cases were exposed to incense smoke, suggesting a possible link between incense smoke and this malignant disease.
Burning incense has also been linked to triggering asthma attacks and respiratory allergies. A 2009 study of children in Oman found that incense burning triggered wheezing in asthmatic children, and a 2015 study found that incense smoke was toxic to cultured cells. While incense burning has not been associated with an increased prevalence of asthma, it can still trigger attacks in those who already have the condition.
In addition to the health risks mentioned above, incense smoke has been associated with an increased risk of heart disease and hypertension. A 2017 study in Chinese adults found that incense burning could contribute to a higher risk of high blood pressure, and studies have also shown that pregnant women exposed to burning incense during pregnancy had a higher risk of hypertensive disorders.
The specific ingredients in incense can vary by region and manufacturer, and different kinds of incense have different scents and materials, with some made from wood, resins, or powders. The combustible binding material found in incense allows it to ignite and produce smoke. This binding material typically includes a bamboo stick, paste, or powder, along with fragrance material and herbal or wood powder.

Burning incense may cause issues with brain health in older adults
Incense is a smoke-emitting substance that has been used for centuries for religious practices, meditation, and hygienic and spiritual purposes. It is typically made up of an aromatic material that produces a scent and a combustible binding material that holds it together in a particular shape. While incense has been associated with various benefits, recent research has also revealed certain health drawbacks.
Burning incense has been linked to several harmful effects, including an increased risk of cancer, respiratory issues such as triggering asthma attacks, and an increased risk of heart disease. A 2008 study in Singapore found a correlation between long-term incense burning and an increased risk of developing lung cancer. Additionally, a 2015 study indicated that incense smoke contains toxic components that can affect cultured cells.
Furthermore, studies have suggested that incense smoke can induce oxidative stress and inflammation, which can lead to vascular dysfunction. This inflammation is caused by the body's processing of particulate matter into metabolites, which can also contribute to overall inflammation in the body. While the precise mechanisms underlying these relationships need further investigation, the impact of incense burning on brain health, particularly in older adults, has been a growing area of interest.
A 2020 study found that burning incense may cause issues with brain health in community-dwelling older adults over the age of 65. This study suggested that long-term air pollution from incense burning could result in smaller brain and prefrontal cortex volumes. However, it is important to note that this study had certain limitations, including a reliance on self-reported data and a lack of real-time indoor air quality monitoring.
While the potential health risks associated with incense burning are concerning, it is worth noting that the correct use of incense to minimize these risks has not yet been fully explored. Additionally, the specific ingredients and types of incense used in studies may not be applicable to all types of incense available, as compositions vary by region and manufacturer. As such, while the health drawbacks of incense burning are important to consider, further research is needed to fully understand the precise mechanisms and extent of these negative effects.

Incense smoke contains particulate matter, gas products, and organic compounds
Incense burning is a common practice in Asian cultures, especially in countries where Buddhism and Taoism are mainstream religions. Incense smoke contains particulate matter, gas products, and organic compounds, which can have adverse health effects.
The particulate matter in incense smoke includes fine particles that can efficiently deposit in the lungs and extra-pulmonary organs, potentially triggering inflammatory reactions. These particles have a large surface area per unit mass, making them effective carriers for harmful inorganic and organic compounds, thereby increasing their toxicity. Studies have shown that incense smoke contains higher levels of particulates compared to cigarette smoke, with an average of 45 mg/g burned for incense versus 10 mg/g burned for cigarettes.
The gas products released from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and others. These gases can contribute to air pollution and have harmful effects on respiratory health.
Incense burning also produces volatile organic compounds (VOCs) such as benzene, toluene, xylenes, aldehydes, and polycyclic aromatic hydrocarbons (PAHs). These compounds are known to be toxic to the lungs and can cause respiratory dysfunction, allergic reactions, and skin and eye irritation. The specific organic compounds emitted can vary depending on the brand of incense sticks, with some containing musk ketones, musk xylenes, musk ambrette, diethylphthalate (DEP), and terpene alcohols.
Additionally, incense smoke has been associated with an increased risk of cancer, particularly upper respiratory tract carcinomas and lung carcinomas. A 2021 study found that incense smoke induced oxidative stress, disrupted tight junctions, and impaired bronchial epithelial barrier integrity in mouse lungs. Furthermore, the concentration of VOCs derived from incense pyrolysis was higher than the fragrance emission concentrations, indicating a significant presence of these harmful compounds in the smoke.

Incense has been used for centuries for religious and medicinal purposes
Incense is an aromatic biotic material that releases fragrant smoke when burnt. It has been used for centuries for religious and medicinal purposes. The term "incense" refers to either the material or the aroma. Incense is composed of aromatic plant materials, often combined with essential oils. The specific ingredients used in incense can vary by region and manufacturer.
The oldest textual source on incense is the Vedas, specifically the Atharvaveda and the Rigveda. Incense-bearing trees were imported from the Arabian and Somali coasts into ancient Egypt, where it was prominent in religious rituals. It was also used in ancient Babylon, Greece, and China. In ancient Egypt, incense was used at the daily liturgy before the cult image of the sun god Amon-Re and in mortuary rites, where it was believed to help the souls of the dead ascend to heaven. The Babylonians used incense extensively while offering prayers or divining oracles, and it was introduced into Israel before the Babylonian Exile (586–538 BC).
Incense has played a significant role in various religious traditions throughout history, including Hinduism, Buddhism, Christianity, and Shinto. In Hinduism and Buddhism, incense is used in rituals, domestic offerings, and daily rites. Buddhists burn incense at festivals, initiations, and rites. In Christianity, incense is used in worship and prayer, symbolising the ascent of the prayers of the faithful to heaven. It is also employed in the celebration of the Eucharist, funerals, and other religious services.
Aside from its religious uses, incense has also been used for medicinal purposes. The practice of using incense as a healing tool was assimilated into the religious practices of ancient times. It is considered the first phase of Ayurveda, where incense is used as an approach to healing. Incense has also been studied for its potential health benefits, with some research suggesting that certain compounds in incense resins may have anti-inflammatory and antidepressant effects.
However, it is important to note that recent studies have also raised concerns about the potential health risks associated with burning incense. Some research suggests that incense smoke contains particulate matter, including carcinogens and irritants, which could lead to respiratory issues and an increased risk of certain diseases. While burning incense is generally considered safe in normal amounts, further research is needed to fully understand its effects on human health.

Burning incense indoors may increase exposure to toxic chemicals
Burning incense is a practice that has been around for centuries, with ancient civilisations such as the Egyptians, Babylonians, and Greeks using it for religious and medicinal purposes. Even today, incense is widely used for a variety of reasons, including aromatherapy, meditation, and creating pleasant aromas. However, recent studies have raised concerns about the potential health risks associated with burning incense, especially indoors.
The smoke released from burning incense contains particulate matter, which refers to the tiny solid and liquid particles that make up the smoke. These particles can be easily inhaled, leading to possible negative health outcomes. The particulate matter in incense smoke includes irritants and carcinogens, which are substances that can cause cancer. While incense is not officially deemed a major public health risk, studies suggest that it can have harmful effects, especially with long-term exposure.
One of the main concerns with burning incense indoors is the release of toxic chemicals, specifically volatile organic compounds (VOCs). These compounds, including benzene and formaldehyde, can accumulate indoors and lead to poor air quality. A study published in the International Journal of Environmental Research and Public Health found that burning incense indoors produced levels of VOCs that exceeded the limits recommended by the World Health Organization (WHO). Prolonged exposure to these toxic chemicals has been associated with various health issues, including respiratory problems, increased risk of cancer, and even developmental delays in infants.
The combustion of incense also produces gas products such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and sulfur dioxide (SO2). Additionally, incense smoke contains polycyclic aromatic hydrocarbons (PAHs) and aldehydes, which have been linked to respiratory dysfunction and increased risk of respiratory diseases. The effects of these chemicals can be particularly harmful to vulnerable individuals, including children, pregnant women, and those with respiratory illnesses such as asthma or COPD.
While the use of incense can have potential health risks, it is important to note that the specific ingredients and effects can vary depending on the type of incense and the region where it is used. Some studies suggest that natural plant-based incense and adequate ventilation can help reduce exposure to harmful chemicals. However, further research is needed to fully understand the complex mixture of gaseous and particulate products released during incense burning and their specific health impacts.
