Burning incense may cause issues with brain health in older adults
Burning incense is a religious ritual practised in many cultures and is especially popular among older adults. Incense is made from a mixture of fragrance materials and herbal, wood, and adhesive powders. When incense is burnt, it releases pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), volatile organic compounds, aldehydes, and polycyclic aromatic hydrocarbons (PAHs). Incense burning is considered a major source of indoor air pollution, with PM levels generated by incense being up to 4.5 times higher than those produced by cigarettes.
Several studies have found that indoor incense burning may negatively impact the brain health of older adults. For instance, a study in Hong Kong associated indoor incense burning with poorer cognitive performance and reduced brain connectivity in older adults. Another study of 515 community older adults without stroke or dementia found that indoor incense burning may induce functional changes in the brain, reducing cognitive resilience and increasing vulnerability to future cognitive decline. These findings suggest that indoor incense burning could be a risk factor for vascular cognitive impairment (VCI), especially given the high prevalence of vascular burden in older adults.
The potential negative impacts of incense burning on brain health in older adults may be due to the increased levels of indoor air pollution it causes. The pollutants released by burning incense have been linked to carcinogenicity, increased cardiovascular mortality, and respiratory conditions. While there is currently a lack of direct evidence linking incense burning to cognitive and brain health issues, the high levels of air pollution it generates are concerning.
Given these potential risks, it is recommended that older adults practise caution when burning incense indoors. Safer alternatives to traditional incense, such as electric incense burners, may be preferable to reduce the potential negative impacts on brain health. Further longitudinal studies are needed to fully understand the precise mechanisms by which incense burning may affect brain health in older adults.

Incense smoke may increase the risk of respiratory symptoms
Incense smoke may pose health risks, but it is not officially deemed a major public health risk comparable to smoking tobacco. However, recent studies have found that incense smoke may increase the risk of respiratory symptoms.
Burning incense releases particulate matter that can be easily inhaled and may have negative health outcomes. This particulate matter contains carcinogens and irritants, which could lead to respiratory diseases such as asthma. Research has also associated incense smoke with the development of respiratory allergies and chronic inflammation in the body.
A cross-sectional health survey among temple workers in Taiwan found that chronic respiratory symptoms, including cough, phlegm, and dyspnea, were more common among them compared to church workers. Even after controlling for potential confounders, cough symptoms remained significantly more prevalent in the temple worker group, suggesting that exposure to incense smoke may increase the risk of respiratory issues.
In addition to the Taiwanese study, a cross-sectional population-based study in China found that incense burning was associated with weekly symptoms of eye, throat, and skin irritation. Furthermore, previous population-based studies among children indicated that incense burning was linked to an increased risk of respiratory symptoms such as asthma, cough, and wheezing. However, it is important to note that another cross-sectional investigation among primary school children in Hong Kong found no significant relationship between incense burning and respiratory problems, suggesting that personal exposure to household incense smoke may be relatively low in terms of concentration and duration.
While the health risks associated with incense burning are a cause for concern, it is worth noting that the correct use of incense to minimize these risks has not yet been fully explored.

Burning incense indoors increases levels of chemicals linked to cancer
Burning incense is a common practice in many parts of the world, especially in Eastern regions, for various purposes, including spiritual and hygienic reasons. However, recent studies have indicated that burning incense indoors increases levels of chemicals that have been linked to cancer.
The smoke released from burning incense contains particulate matter that can be easily inhaled and may have negative health outcomes. While incense is not officially deemed a major public health risk comparable to smoking tobacco, its long-term use has been associated with an increased risk of certain types of cancer. For example, a study in 2021 confirmed the presence of carcinogenic compounds in incense smoke, which could contribute to cancer development.
The combustion of incense generates particulate matter in the 2.5 μm size range and below, which is known to cause lung and respiratory illnesses above certain concentrations. Additionally, incense smoke has been associated with neoplasm, and extracts of particulate matter from incense smoke have been found to be mutagenic. This means that incense smoke has the potential to damage cells and their genetic contents, which is linked to the development of cancers.
Furthermore, the use of incense has been linked to an increased risk of respiratory symptoms, including cough, phlegm, and dyspnea. A study comparing temple workers to church workers in Taiwan found that chronic respiratory symptoms were more prevalent in the group exposed to incense smoke. While the precise mechanisms behind these associations are still being investigated, the current evidence suggests that burning incense indoors can increase levels of chemicals linked to adverse health effects, including cancer.
It is important to note that the health risks associated with burning incense may depend on the type of incense, the frequency of use, and the ventilation of the indoor space. Further research is needed to fully understand the impact of incense smoke on human health and to determine guidelines for correct and safe use.

Incense smoke contains toxic compounds and particulate matter
Incense burning is a common practice in many parts of the world, especially in the East, for various purposes, including religious, hygienic, and spiritual reasons. However, recent studies have revealed potential health drawbacks associated with the practice.
Incense smoke contains particulate matter that can be easily inhaled and may have negative health outcomes. The combustion of incense generates particulate matter in the 2.5 μm size range and below, which is known to cause lung and respiratory illnesses above certain concentrations. These fine particles have been linked to respiratory symptoms such as cough, phlegm, and dyspnea, and can lead to respiratory system dysfunction and allergic contact dermatitis.
Furthermore, incense smoke has been found to contain toxic compounds, including volatile organic compounds such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). PAHs are produced by burning any organic material, including tobacco leaves, coal, or incense sticks, and have been linked to cancer. While the precise mechanisms behind these associations are still being investigated, the existing evidence suggests that long-term exposure to incense smoke may contribute to an increased risk of cancer and other health issues.
It is important to note that the health risks associated with incense burning depend on various factors, including the type of incense, the frequency of use, and the ventilation of the indoor environment. While some studies suggest that normal amounts of incense burning do not pose a significant risk, others indicate that chronic and high-quantity exposure to the chemicals in incense smoke can have adverse effects.

Incense smoke may be more harmful than cigarette smoke
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 used for divine worshipping, ancestor veneration, and even for hygienic purposes. However, recent studies have shown that incense smoke may be more harmful than previously thought and could potentially be more harmful than cigarette smoke.
A growing body of epidemiological and experimental evidence has reported the negative effects of incense use on human well-being. Incense smoke contains particulate matter that can be easily inhaled and can have negative health outcomes. The combustion of incense produces fine particles that are known to cause lung and respiratory illnesses above certain concentrations. These particles are smaller than 10μm and especially smaller than 2.5μm in size, which is associated with respiratory morbidity.
The burning of incense also produces volatile organic compounds such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These chemicals are released into the air and can cause respiratory system dysfunction when inhaled. Incense smoke has been associated with an increased risk of heart disease, asthma, and cancer. A 2021 study also confirmed that some of the particulate matter in incense smoke was carcinogenic.
While the direct link between incense burning and cancer is still being debated, a study in Singapore found that incense use is generally safe in normal amounts, and the risk of cancer is very small, if at all. However, another study showed that incense smoke is more cytotoxic and genotoxic than cigarette smoke, meaning it is potentially more toxic to cells and their genetic contents. This could be due to the fact that incense smoke consists almost exclusively (99%) of ultrafine and fine particles, which are likely to have adverse health effects.
In conclusion, while the direct comparison between incense smoke and cigarette smoke is complex due to different usage patterns and frequencies, the evidence suggests that incense smoke may be more harmful than previously believed and could pose serious health risks, especially with long-term exposure.
