Incense is a smoke-emitting substance that has been burned for centuries as part of religious ceremonies and cultural practices. It is also commonly used for hygienic purposes, to improve indoor scents, and even for mindfulness practices. However, the inhalation of incense smoke has recently come under scrutiny due to its potential negative health effects. The smoke from burning incense contains particulate matter, gas products like carbon monoxide, and organic compounds such as volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). These particles and compounds are small enough to be inhaled, reaching deep into the respiratory tract and even the bloodstream. Research has linked exposure to these substances with adverse health effects, including respiratory issues, asthma, lung inflammation, and an increased risk of certain types of cancer. While the precise mechanisms behind these associations are still being investigated, it is generally recommended to avoid directly inhaling incense smoke and to ensure proper ventilation when using incense.

Incense smoke contains particulate matter, which is linked to respiratory issues
Burning incense is a common practice in many cultures and religions. It is also used to improve the scent of indoor areas. However, recent research has revealed potential health risks associated with incense burning.
The size of the particles in the particulate matter is crucial in understanding their potential health impact. Particles smaller than 10 μm in diameter (PM10) are of particular concern as they can be inhaled and accumulate in the respiratory system. On average, incense burning produces particulates greater than 45 mg/g, which is significantly higher than the amount produced by cigarettes (10 mg/g).
In addition to particulate matter, incense smoke also contains gas products and organic compounds, such as carbon monoxide, formaldehyde, nitrogen dioxide, benzene, and polycyclic aromatic hydrocarbons (PAHs). Exposure to these gases and compounds can have harmful effects on health, including headaches, dizziness, weakness, and nausea, and aggravation of existing cardiovascular diseases.
While the health risks of incense burning are important to consider, it is worth noting that the addition of calcium carbonate to incense can reduce particulate emissions by up to 40%, potentially making it safer to use. It is also recommended to increase ventilation when burning incense by opening windows and doors to improve airflow and reduce the concentration of harmful compounds in the air.

The inhalation of incense smoke may cause lung inflammation and cancer
Burning incense is a popular practice across many cultures and religions. However, recent research has revealed some potential health drawbacks to inhaling incense smoke.
Incense smoke contains particulate matter (PM), gas products, and organic compounds. The particulate matter in incense smoke is small enough to be inhaled and can accumulate in the respiratory system, causing respiratory system dysfunction. These particles can travel deep into the respiratory tract, reaching the lungs and even the bloodstream. The gas products from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and volatile organic compounds (VOCs) such as benzene, toluene, and xylenes. Exposure to these gases can have harmful effects on health, with low concentrations of carbon monoxide causing headaches, dizziness, weakness, and nausea, and high concentrations being potentially fatal. Nitrogen dioxide and sulfur dioxide exposure can lead to reduced work capacity, aggravation of cardiovascular diseases, negative effects on pulmonary function, respiratory illnesses, lung irritation, and changes to the lung's defense system.
The organic compounds in incense smoke, such as benzene, toluene, and xylenes, are also cause for concern. These compounds are absorbed onto the particulate matter, and it is difficult to determine the specific health effects of each component in the complex mixture that is inhaled. However, studies have shown a correlation between incense use and certain health issues, including asthma, lung inflammation, and cancer.
A 2021 study confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could cause cancer. There is an association between higher cancer risk and incense use, particularly for upper respiratory cancers and squamous cell lung cancer. While the precise mechanisms behind these relationships are still being investigated, the available research suggests that inhaling incense smoke may contribute to lung inflammation and cancer, along with other respiratory and health issues.

Burning incense produces volatile organic compounds, which are harmful
Burning incense is a common practice in many cultures and religions. However, recent research has revealed potential health risks associated with incense smoke inhalation. One significant concern is the presence of volatile organic compounds (VOCs) emitted during incense burning. These compounds, including benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs), pose a threat to human health when inhaled.
The smoke produced by burning incense contains particulate matter, which refers to small particles that can be inhaled and accumulate in the respiratory system. These particles can be as small as 10 μm in diameter or less, allowing them to penetrate deep into the respiratory tract, reaching the lungs and even the bloodstream. This particulate matter has been linked to respiratory issues, including asthma and lung inflammation.
Additionally, the volatile organic compounds released during incense burning contribute to indoor air pollution and can have harmful effects on overall health. The complex mixture of particulate matter, gas products, and organic compounds in incense smoke makes it challenging to isolate the specific health impacts of each component. However, studies have found associations between incense use and increased cancer risk, as well as other health issues.
For example, a 2020 study suggested that long-term exposure to incense smoke may negatively impact brain health in older adults over 65 years of age. The study reported delays in cognitive performance and reduced brain connectivity, potentially due to the air pollution caused by incense burning. While further research is needed to fully understand the mechanisms behind these associations, the existing evidence suggests that caution should be exercised when using incense.
It is worth noting that the composition of incense varies, and different types of incense may have different health effects. Some studies have used specific types of incense, so the results may not be generalizable to all varieties. Additionally, many studies on incense burning and its health effects have been conducted on animals, primarily rats, rather than humans. Therefore, while the potential risks of inhaling incense smoke are concerning, more comprehensive human-based research is required to definitively conclude the impact of incense smoke on various health conditions.

Incense smoke contains natural and unnatural ingredients, some of which are carcinogenic
Burning incense is a popular practice worldwide, with many cultures burning incense for hygienic, spiritual, and health purposes. Incense smoke contains a mixture of natural and unnatural ingredients, which, when burned, release particulate matter that can be easily inhaled and may lead to negative health outcomes.
Incense is usually made from natural materials such as sage, resins, oils, and wood. However, incense makers have started adding more materials to enhance fragrance, improve burnability, and help hold the incense blend materials together. These additional ingredients can include unnatural substances, such as glues and other chemicals, which may release harmful toxins when burned.
A 2021 study confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could cause cancer. Burning incense has also been associated with an increased risk of developing respiratory allergies, asthma, heart disease, and brain health issues in older adults. The particulate matter in incense smoke contains carcinogens and irritants, which are harmful to the respiratory system and can trigger chronic inflammation in the body.
While the largest study on the topic, which tracked 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, it is still important to be cautious. To reduce the potential risks associated with burning incense, it is recommended to limit incense use and exposure to the smoke, ensure proper ventilation during and after use, and explore alternative options if you are concerned about the potential health implications.

Incense smoke has been associated with an increased risk of heart disease
Burning incense is a popular practice worldwide, with a long history in many cultures and religions. Incense smoke contains particulate matter that can be easily inhaled and may have negative health outcomes. While incense has been associated with various health benefits, recent studies have also revealed potential health drawbacks.
Several studies have found a correlation between incense smoke and an increased risk of heart disease. For example, a study of 50 households in Taipei found that incense burning was associated with increased indoor levels of PM2.5, which can affect heart rate variability and increase the risk of cardiovascular diseases (CVDs). Another large population-based cohort study of middle-aged and elderly Chinese individuals in Singapore found that chronic exposure to daily incense burning for over 20 years was associated with a 12% increased risk of cardiovascular mortality, including a 10% higher risk of coronary heart disease and a 19% increased risk of stroke, compared to former or never users.
Animal studies have also provided evidence of the adverse effects of incense smoke on heart health. Experiments on rats exposed to incense smoke observed metabolic changes, ultrastructural alterations in heart muscle tissue, and cardiac hypertrophy, indicating potential damage to cardiac tissue. Furthermore, incense smoke exposure was linked to increased levels of inflammatory molecules and oxidative stress in rat heart tissues, which are known contributors to cardiovascular diseases.
The particulate matter in incense smoke contains irritants and carcinogens, which can lead to respiratory issues and potentially trigger asthma. It is important to note that the studies suggest an association between incense use and health risks, but they do not establish a direct causal relationship. However, the presence of carcinogens and the potential for respiratory problems underscores the importance of further research to fully understand the health implications of incense smoke exposure.
