Incense is a popular way to add fragrance to homes and temples, but it is important to use it safely. Burning incense produces particulate matter, including volatile organic compounds like benzene, toluene, and polycyclic aromatic hydrocarbons (PAHs), which are hazardous chemicals that can cause respiratory problems, eye irritation, and nausea. Studies have also found associations between incense use and cancer, asthma, and heart disease, although causation has not been established. To reduce the risks associated with incense, it is recommended to burn it in a well-ventilated area and avoid sleeping with it burning in the bedroom.

Incense smoke contains carcinogens and irritants, which can lead to respiratory issues like asthma
Incense has been used for thousands of years for hygienic, spiritual, and aesthetic purposes. However, recent studies have found that incense smoke contains particulate matter, including carcinogens and irritants, which can lead to respiratory issues, particularly for those who already have asthma.
A typical composition of stick incense consists of herbal and wood powder, fragrance material, adhesive powder, and a bamboo stick. The burning of incense produces particulate matter, gas products, and organic compounds. On average, incense burning produces more particulates than cigarettes (45 mg/g burned compared to 10 mg/g burned). The gas products from burning incense include CO, CO2, NO2, and SO2, as well as volatile organic compounds such as benzene, toluene, and xylenes, which are hazardous chemicals that can cause respiratory issues.
The smoke released from incense has a pleasant smell, but it can also contain small, inhalable particulate matter that can have negative health outcomes. A 2021 study confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could cause cancer. While there is only a correlation between incense use and cancer, with no causal relationship established, the use of incense has been associated with an increased risk of upper respiratory tract and lung carcinomas.
In addition to the health risks, burning incense indoors can also increase the risk of fires, especially if the incense is not properly extinguished or if it is burned on flammable surfaces. To reduce the risks associated with incense use, it is recommended to burn incense in a well-ventilated area, open windows to disperse smoke, and explore alternative ways to enjoy the scent of incense, such as oil diffusers.

Burning incense indoors increases the levels of chemicals called polycyclic aromatic hydrocarbons (PAHs), which have been linked to cancer
Burning incense is a popular way to add fragrance to indoor spaces. However, it is important to be aware of the potential health risks associated with it. Burning incense indoors increases the levels of chemicals called polycyclic aromatic hydrocarbons (PAHs), which have been linked to cancer.
PAHs are organic compounds that are released into the air when organic materials such as incense, tobacco, or coal are burned. These compounds can have harmful effects on human health, and their presence in the air has been documented to cause respiratory system dysfunction. A 2021 study confirmed that some of the particulate matter in incense smoke, including PAHs, is carcinogenic, meaning it could lead to cancer.
The smoke from burning incense also contains other hazardous chemicals and pollutants, such as benzene, toluene, aldehydes, and volatile organic compounds. These chemicals can cause a range of health issues, including respiratory problems, eye irritation, nausea, and allergies. Burning incense has also been associated with elevated cord blood IgE levels and allergic contact dermatitis.
It is worth noting that the largest study on incense use and cancer, which tracked 61,000 people in Singapore, found that incense use is generally safe in normal amounts and the risk of cancer is very small, if at all. However, it is still advisable to take precautions when burning incense indoors. To reduce exposure to hazardous chemicals, it is recommended to burn incense in a well-ventilated area and to open windows or use a fan to disperse the smoke.

Burning incense may negatively impact brain health in older adults
Burning incense is a popular activity worldwide, with a long history of use in spiritual practices and for hygienic purposes. However, recent studies have suggested that burning incense may negatively impact brain health, particularly in older adults.
A 2020 study found a link between burning incense and brain health issues in older adults over 65 years of age. The study reported delays in cognitive performance and a decrease in brain connectivity, with long-term incense use potentially resulting in reduced brain and prefrontal cortex volumes. These findings indicate that incense burning may contribute to cognitive decline and impaired brain function in older individuals. While the precise mechanisms behind these associations require further investigation, the study highlights potential health risks associated with incense use.
The negative impact of incense smoke on brain health may be attributed to the release of pollutants during burning. Incense smoke contains 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 and have been linked to adverse health effects. The high levels of PM generated by incense burning, up to 4.5 times that of cigarettes, are particularly concerning.
Additionally, incense smoke has been associated with increased cardiovascular mortality and respiratory conditions. It can induce oxidative stress and inflammation, leading to vascular dysfunction. The water-soluble factions in particulate matter can accelerate membrane lipid peroxidation, further contributing to health issues. These health risks are supported by a Chinese cohort study, which found a positive association between prenatal exposure to incense burning and early-onset hyperactive behaviors in preschoolers.
While the use of incense is not officially deemed a major public health risk comparable to smoking tobacco, the growing body of evidence suggests that it may have detrimental effects on brain health, particularly in older adults. Further research is needed to fully understand the mechanisms behind these associations and to determine the specific health risks posed by different types of incense. In the meantime, it is advisable to reduce exposure to incense smoke and ensure proper ventilation when using it.

Burning incense in a poorly ventilated room can cause a hazardous build-up of smoke
Burning incense has been a common practice for thousands of years, with many cultures burning it for spiritual, hygienic, and aesthetic purposes. While it can make your home smell wonderful and create a relaxing atmosphere, it's important to be aware of the potential health risks associated with inhaling incense smoke.
The smoke from burning incense contains a variety of hazardous chemicals, including benzene, toluene, and polycyclic aromatic hydrocarbons (PAHs). These chemicals are released into the air and can be inhaled, potentially causing respiratory problems, eye irritation, and nausea. In addition, a 2021 study confirmed that some of the particulate matter in incense smoke is carcinogenic, meaning it could lead to cancer, specifically upper respiratory tract carcinomas or lung carcinomas.
When incense is burned in a poorly ventilated room, the concentration of these hazardous chemicals can build up, posing a serious health hazard. The lack of airflow prevents the smoke from dispersing, increasing the amount of smoke and harmful chemicals that are inhaled. This is particularly dangerous for individuals with asthma, as the smoke can trigger an attack.
To reduce the risks associated with burning incense, it is recommended to always burn incense in a well-ventilated area. Opening a window or turning on a fan can help disperse the smoke and reduce your exposure to hazardous chemicals. Burning incense on a heat-resistant surface and using an incense holder to keep it upright can also help prevent fires. Additionally, individuals with asthma or allergies should be cautious and stop burning incense if they experience any negative symptoms.

Burning incense near flammable surfaces can be a fire hazard
Incense burning has been a common practice for centuries, especially in Asian countries where Buddhism and Taoism are mainstream religions. While incense can create a pleasant fragrance and serve various purposes, it is important to be cautious when burning it due to the potential health and safety hazards it poses.
One significant concern is the fire hazard associated with burning incense near flammable surfaces. It is crucial to remember that both the burning incense and the resulting ash can easily ignite flammable materials nearby. This includes surfaces made of wood or fabric, which should be avoided when placing incense. Always use a heat-resistant surface to burn incense and ensure that any holders or burners are specifically designed for this purpose. A simple holder can be made safer by placing a ceramic dish or plate underneath to catch any falling ash.
Additionally, be cautious when burning multiple incense sticks. It is a common cause of fires when one stick accidentally lights another, causing it to burn through and fall outside the holder with its tip still lit. Always ensure that the ash from one stick does not fall onto another, and be mindful of the potential for sticks to topple over and start a fire.
Proper burning and disposal techniques are essential to minimise the fire risk. Never leave incense unattended, and always ensure it is fully extinguished before disposal. Bending the stick until it snaps in half or blowing it out are effective methods of extinguishing incense sticks. Remember, even after extinguishing, there may still be hot embers that can cause burns or start a fire if not properly cooled.
By following these safety precautions, you can enjoy the benefits of burning incense while significantly reducing the risk of fire hazards.
