Incense smoke contains particulate matter, gases, and organic compounds that can be inhaled
Incense is a smoke-emitting substance that is burned for hygienic, spiritual, aesthetic, religious, aromatherapy, and ceremonial reasons. It is composed of aromatic plant materials, often combined with essential oils. The smoke released has a sweet, pleasant smell. However, it also contains particulate matter, gases, and organic compounds that can be inhaled and may have negative health outcomes.
The particulate matter in incense smoke includes solid particles ranging from 10 to 500 nanometres (4×10^-7–2×10^-5 inches) in diameter. Particles less than 10 μm in diameter (PM10) can accumulate in the respiratory system, with smaller particles able to penetrate deeper. Ultrafine particles less than 0.1 μm are believed to pose the largest health risks as they can reach the alveoli. While there have been no direct reports of the ill effects of incense smoke particles on human health, the composition of incense smoke in terms of pollutants and toxicological effects is important to understand.
The gaseous products from burning incense include carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx), sulfur oxides (SOx), and other volatile organic compounds (VOCs) such as benzene, toluene, musk ketones, and xylenes. Carbon monoxide is poisonous and can cause headaches, dizziness, weakness, and nausea in low concentrations, while high concentrations can be fatal. Sulfur dioxide, nitrogen dioxide, and VOCs can also have harmful health effects, including respiratory illnesses, lung irritation, and alterations to the lung's defence system.
Additionally, incense smoke contains organic compounds such as polycyclic aromatic hydrocarbons (PAHs), aldehydes, musk xylenes, musk ambrette, diethylphthalate (DEP), and toxic metals. These compounds have been linked to respiratory system dysfunction and increased risk of respiratory diseases, allergies, and asthma. Some organic compounds in incense smoke, such as aldehydes and PAHs, are also carcinogenic and mutagenic. While incense is not deemed a major public health risk, studies suggest that it can pose certain health dangers, especially with prolonged exposure and inadequate ventilation.

Inhaling incense smoke may cause respiratory issues and increase the risk of cancer
Burning incense is a popular practice worldwide, but it is important to use it safely. While incense smoke contains aromatic compounds, it also contains many toxic and irritant compounds. These compounds are released into the air when incense is burned and can be easily inhaled, potentially causing respiratory issues and increasing the risk of cancer.
The smoke released from burning incense contains particulate matter, gas products, and organic compounds. Particles less than 10 μm in diameter (PM10) can accumulate in the respiratory system, with particles less than 2.5 μm (PM2.5) believed to pose the most significant health risks as they can reach the alveoli. While there are no direct reports of the negative health effects of incense particles, the complex mixture of pollutants in incense smoke can cause respiratory issues.
Inhaling incense smoke can lead to respiratory dysfunction and trigger asthma and other respiratory allergies. A 1966 study by Sturton et al. found a high incidence of nasopharyngeal carcinoma in Hong Kong patients who burned incense, suggesting a possible link between incense smoke and malignant diseases. Additionally, incense smoke has been associated with an increased risk of heart disease and potential issues with brain health in older adults.
The effects of inhaling incense smoke can be similar to those of cigarette smoke, including dizziness, high blood pressure, and anxiety. Carbon monoxide, a poisonous gas formed during the incomplete combustion of incense, can cause headaches, dizziness, weakness, and nausea in low concentrations, and can be fatal in high concentrations. It is important to note that incense ash can also be harmful if inhaled, so it is recommended to wash your hands after handling incense and to keep pets away from the smoke.
While some studies suggest that burning incense may increase the risk of cancer, particularly upper respiratory tract and lung carcinomas, other research indicates that incense use is safe in normal amounts, and the risk of cancer is very small. Consumers should be cautious when interpreting studies, as many rely on animal subjects or burning incense in enclosed spaces, which may not accurately represent the risks for humans in well-ventilated areas.

Incense ash can be harmful if inhaled or ingested, causing skin irritation
Incense has been used for thousands of years, and it is a popular way to add fragrance to your home. However, it is important to use it safely. Incense smoke contains a complex mixture of particulate matter, gaseous products, and organic compounds. These include volatile organic compounds (VOCs), musk ketones, musk xylenes, musk ambrette, aldehydes, polycyclic aromatic hydrocarbons, and diethylphthalate (DEP). Many of these compounds are toxic and can have negative health outcomes when inhaled.
Particulate matter in incense smoke can contain carcinogens and irritants, which could lead to respiratory diseases such as asthma. Burning incense may also trigger asthma attacks and has been associated with an increased risk of developing respiratory allergies and childhood asthma. In 1966, a study by Sturton et al. reported a high incidence of nasopharyngeal carcinoma in male patients who burned incense. The study suggested that incense smoke may be a factor in the development of this malignant disease.
In addition to the health risks associated with inhaling incense smoke, the ash produced by burning incense can also be harmful if inhaled or ingested. It is important to wash your hands after handling incense ash, as it can irritate the skin. When burning incense outdoors, be mindful of the wind direction, as the ash can be blown into your face or eyes and cause irritation. Incense ash can also damage surfaces such as wood, furniture, or floors, and cause discolouration.
To minimize the risks associated with burning incense, it is recommended to use high-quality incense sticks made from natural materials such as wood, bamboo, or spices. These materials are less likely to produce harmful smoke when burned. Always use an incense holder or stand to keep the sticks upright and prevent fires. Look for holders made from heat-resistant materials such as crystal, metal, or ceramic, as these are safer to use.

Burning incense produces carbon monoxide, which can be dangerous at high concentrations
Burning incense produces smoke that contains particulate matter, volatile organic compounds, and carbon monoxide. While the practice of burning incense has been popular for thousands of years, it is important to understand the potential health risks associated with inhaling incense smoke.
Carbon monoxide (CO) is a colourless, odourless, and tasteless gas that is formed during the incomplete combustion of organic substances, such as wood, incense, and cigarettes. CO has a high affinity for haemoglobin, reducing the blood's capacity to transport oxygen. Inhalation of CO can have adverse health effects, depending on the duration and intensity of exposure. At low concentrations, CO can cause headaches, dizziness, weakness, and nausea. These symptoms are similar to those experienced by individuals who reported inhaling incense smoke directly.
At high concentrations, carbon monoxide can be dangerous and even fatal. A study investigating carbon monoxide levels in homes found that burning incense sticks can lead to CO concentrations above the World Health Organization (WHO) guideline levels. Each joss stick can produce up to 557mg of CO, compared to 60mg from a typical cigarette. Burning just two incense sticks in a sealed room can exceed the WHO's 1-hour guideline level for CO within an hour.
Therefore, it is essential to take precautions when burning incense. Ensure proper ventilation and avoid inhaling the smoke directly. Keep the room well-ventilated and avoid allowing the smoke to build up. It is also important to be mindful of the potential health risks associated with incense smoke, particularly the presence of carbon monoxide, and take steps to mitigate these risks.
