Incense smoke contains carcinogens and irritants, which can lead to respiratory diseases
Incense has been used for centuries and is associated with religious practices and meditation. However, recent studies have highlighted potential health risks associated with burning incense, particularly indoors.
Incense smoke contains a variety of 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). These pollutants contribute to indoor air pollution, with incense generating up to 4.5 times more PM than cigarettes.
The presence of these pollutants in incense smoke has been linked to several adverse health effects. One of the most concerning findings is the association between incense smoke and respiratory diseases. The particulate matter in incense smoke contains carcinogens and irritants, which can lead to respiratory issues and an increased risk of respiratory tract carcinomas or lung carcinomas. A 2008 study in Singapore found a link between long-term incense burning and an increased risk of developing squamous cell lung cancer.
Additionally, incense burning can trigger asthma attacks, as evidenced by a 2009 study in Oman that reported wheezing in asthmatic children exposed to incense smoke. While incense burning is not associated with an increased prevalence of asthma, it can aggravate existing respiratory conditions.
The adverse effects of incense smoke are not limited to the respiratory system. Studies have also found associations with increased cardiovascular mortality and neurological impacts. Incense burning has been linked to accelerated cognitive aging, intellectual decline, and an increased risk for Alzheimer's Disease and vascular dementia. Furthermore, regular indoor incense burning has been associated with poorer performance across multiple cognitive domains and decreased brain connectivity, particularly in older adults.
While the potential health risks of incense burning are concerning, it's important to note that some studies suggest possible benefits as well. Certain compounds in incense resins, such as frankincense and myrrh, have shown antidepressant and anti-inflammatory effects in mice. However, more research is needed to fully understand the complex effects of incense on the brain and overall health.

Incense smoke releases pollutants, which are associated with accelerated cognitive ageing and an increased risk of Alzheimer's
Burning incense is a popular practice across many cultures and religions. However, recent research has revealed potential health drawbacks. Incense smoke releases various 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). These pollutants are associated with adverse health effects, such as respiratory conditions, cardiovascular issues, and an increased risk of certain types of cancer.
Several studies have linked indoor incense burning to cognitive and brain health impacts in older adults. Specifically, regular indoor incense burning has been associated with poorer performance across multiple cognitive domains over a three-year period. While structural brain changes were not evident in these studies, a subtle impact on the functional connectivity of the default mode network (DMN) was observed. The DMN is active during rest and self-referential processing, and its proper functioning is crucial for various cognitive processes. Disruption of the DMN has been linked to neurological and psychiatric conditions, including attention-deficit/hyperactivity disorder, autism spectrum disorder, and schizophrenia.
Furthermore, the pollutants released from incense smoke are associated with accelerated cognitive ageing, intellectual decline, and an increased risk of Alzheimer's Disease (AD) and vascular dementia. This is particularly relevant for older adults, as the potential links between incense burning and cognitive decline could have far-reaching public health implications for cultures that widely use incense in worship rituals. Therefore, the findings from these studies emphasize the importance of adopting safer practices when burning incense, such as avoiding indoor burning or exploring alternative options.
While the direct impact of incense smoke on brain structure requires further investigation, the existing research highlights the complex relationship between incense burning, air pollution, and its potential effects on cognitive health. It is crucial to approach incense burning with caution and be mindful of the potential risks associated with prolonged exposure to its pollutants. Understanding these risks can help individuals make informed decisions about their incense use and implement safety measures to minimize any adverse health consequences.

Incense smoke may cause a response similar to antidepressants and activate receptors associated with warmth
Burning incense has been a common practice across various cultures and for various purposes, including religious practices and meditation. While incense burning is considered a major source of indoor air pollution, with pollutants such as particulate matter (PM), carbon monoxide (CO), and volatile organic compounds being released into the air, there are also some potential benefits associated with the practice.
A 2008 study in cell cultures and mice identified a compound in frankincense resin that could cause a response similar to an antidepressant. This compound activated receptors in the brain associated with a feeling of warmth and affected areas of the brain associated with anxiety and depression. Additionally, a 2017 study found that some compounds isolated from frankincense and myrrh resins exhibited an anti-inflammatory effect in mice. These findings suggest that incense smoke may have some positive effects on brain function and mental health.
However, it is important to consider the potential drawbacks as well. Several studies have linked incense burning to negative health effects, particularly respiratory issues and cancer. A 2008 study in Singapore found that long-term incense burning was associated with an increased risk of developing squamous cell lung cancer. Incense smoke contains carcinogens and irritants that can lead to respiratory diseases, and a 2009 study found that it triggered wheezing in asthmatic children. Additionally, incense burning has been associated with increased cardiovascular mortality and an increased risk of high blood pressure.
While the potential risks of incense burning cannot be ignored, it is important to note that some of these risks may be mitigated by practising safer incense burning techniques, such as avoiding burning incense indoors or using alternative methods that produce fewer pollutants. Overall, while incense burning may offer some potential benefits to brain function and mental health, it is important to weigh these against the potential health risks associated with the practice.
