Incense is a product that creates a smell when burned, and it has been used for centuries as an integral part of religious ceremonies and cultural practices. While incense is widely used, there are concerns about its potential health risks. Studies have associated incense smoke with an increased risk of asthma, heart disease, and cancer, suggesting that it can trigger chronic inflammation in the body and cause issues with brain health in older adults. However, it is important to note that the existing studies only show a correlation and do not establish a causal relationship between incense and these diseases. While the occasional burning of incense in well-ventilated spaces is generally considered safe, regular and excessive exposure to incense smoke, especially in enclosed areas, can lead to high levels of indoor air pollutants and potentially negative health outcomes.

What You'll Learn
Incense smoke and air pollution
Burning incense is a popular practice worldwide, with a long history in many cultures and religions. However, recent studies have highlighted potential health risks associated with incense smoke, particularly concerning indoor air pollution.
Incense smoke releases 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 can accumulate in small, enclosed spaces, leading to high levels of indoor air pollution. The concentration of particulate matter in incense smoke can be up to 4.5 times higher than that of cigarette smoke, with incense producing over 45 mg/g compared to 10 mg/g for cigarettes.
The health risks associated with incense smoke include respiratory issues, increased cardiovascular mortality, and potential carcinogenic effects. A 2021 study found that some of the particulate matter in incense smoke is carcinogenic, and a high incidence of nasopharyngeal cancer was observed in a group of male patients in Hong Kong who were exposed to incense smoke. Additionally, incense smoke has been linked to respiratory system dysfunction, with higher exposure associated with increased cough symptoms in children.
Furthermore, incense burning has been identified as a potential risk factor for adverse cognitive and brain health, particularly in older adults. While the precise mechanisms are still being investigated, studies suggest that incense smoke can induce oxidative stress and inflammation, leading to vascular dysfunction.
To mitigate the potential health risks associated with incense burning, it is recommended to improve ventilation by opening windows and doors, choose incense made from natural, plant-based ingredients without harmful chemicals, and consider smokeless or low-smoke alternatives.

Incense poisoning
Incense is a product that creates a smell when burned. Incense poisoning can occur when someone inhales or swallows liquid incense, either by accident or on purpose. Solid incense is not considered poisonous.
The signs and symptoms of incense poisoning vary from person to person and depend on the type of chemical involved. The affected body systems include the digestive system, respiratory system, vascular system, skin, and ENT. Symptoms may include burning and associated pain in the mouth and throat, which may also affect the nose, ears, and eyes. Respiratory difficulties can occur if a substantial amount of incense fumes are inhaled. In more severe cases, there may be a bluish discolouration of the skin beneath the fingernails and on the lips.
If liquid incense comes into contact with the skin or eyes, flush the affected area with water for at least 15 minutes. If someone has swallowed liquid incense, give them water or milk right away, unless advised otherwise by a healthcare professional. Do not give anything to drink if the person has symptoms that make it difficult to swallow.
The prognosis of incense poisoning depends on the amount of substance consumed, the time between consumption and treatment, the severity of the symptoms, and the general health status of the patient. If the individual can recover from the symptoms with appropriate medication and early support, the outcome is generally good. However, swallowing large quantities of liquid incense can result in severe symptoms and complications and can even be fatal.
To reduce the negative effects of incense burning, it is recommended to increase ventilation by opening windows and doors to improve airflow. Switching to a safer type of incense made from natural, plant-based ingredients without harmful chemicals can also help reduce air pollutants.

Incense and respiratory health
Burning incense is a popular practice across many cultures and religions. It is also used in mindfulness practices like yoga and meditation. However, recent research has revealed some health drawbacks, particularly concerning respiratory health.
Incense smoke contains particulate matter, which can be easily inhaled and may lead to negative health outcomes. The particulate matter in incense smoke has been found to contain carcinogens and irritants, which could lead to respiratory diseases such as asthma. Burning incense has also been associated with an increased risk of developing respiratory allergies and childhood asthma. Additionally, a 2020 study found that burning incense may cause issues with brain health in older adults over 65, including delays in cognitive performance and decreased brain connectivity. This is thought to be linked to long-term air pollution caused by incense burning.
Furthermore, incense smoke has been found to increase indoor air pollutants, especially when burned in small, enclosed spaces. The smoke contains gases such as carbon monoxide, nitrogen dioxide, and sulfur dioxide, as well as volatile organic compounds like benzene, aldehydes, and polycyclic aromatic hydrocarbons (PAHs). PAHs have been linked to cancer, particularly of the upper respiratory tract and lungs. However, it is important to note that the largest study to date, tracking 61,000 people in Singapore, found that incense use is safe in normal amounts and the risk of cancer is very small, if at all.
To reduce the potential health risks associated with incense burning, it is recommended to increase ventilation by opening windows and doors to improve airflow. Switching to a safer type of incense made from natural, plant-based ingredients without harmful chemicals can also help reduce air pollutants. Smokeless or low-smoke incense is another alternative to consider. Additionally, using an indoor air purifier can help reduce the accumulation of pollutants, but it may not completely eliminate them.

Incense and brain health
While incense has been used for centuries as part of religious ceremonies and cultural practices, recent studies have raised concerns about its potential impact on brain health. The burning of incense releases various pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen dioxide (NO2). These pollutants contribute to indoor air pollution and have been linked to respiratory conditions, cardiovascular issues, and increased risk for Alzheimer's disease and vascular dementia.
Several studies have found a correlation between incense burning and cognitive decline, particularly in older adults. One study reported that indoor incense burning was associated with poorer cognitive performance over three years, decreased brain connectivity, and an interaction with vascular disease that predisposed participants to poor cognitive performance. However, it is important to note that the study had limitations, including potential reporting bias as incense use habits were self-reported.
The mechanisms underlying the relationship between incense burning and cognitive changes are not yet fully understood. While the exact causal link between incense burning and brain health remains to be established, the pollutants released during incense burning have been associated with accelerated cognitive aging and intellectual decline. The impact of incense smoke on vascular health is particularly noteworthy, as it can induce oxidative stress and inflammation, leading to vascular dysfunction.
To mitigate the potential risks associated with incense burning, it is recommended to improve ventilation by opening windows and doors, ensuring adequate airflow, and avoiding direct inhalation of smoke. Additionally, switching to safer types of incense made from natural, plant-based ingredients without harmful chemicals can help reduce the release of air pollutants. Smokeless or low-smoke incense options are also available. For those who regularly burn incense, using an indoor air purifier can help reduce the accumulation of pollutants, although it may not completely eliminate them.
While the findings suggest a correlation between incense burning and cognitive decline, more research is needed to establish a direct causal relationship. The cultural and religious significance of incense burning must also be considered, and alternative practices or safer incense alternatives may be recommended to reduce potential health risks. Overall, while incense burning may have some negative impacts on brain health, further investigations are required to fully understand the underlying mechanisms and develop effective mitigation strategies.

Incense and heart disease
Burning incense is a common practice worldwide, with a long history of use in religious ceremonies and for spiritual purposes. However, recent inquiries have raised concerns about its potential health risks.
Incense smoke contains volatile organic compounds and particulate matter, which can be easily inhaled and have negative health outcomes. The particulate matter in incense smoke includes carcinogens and irritants, which are linked to respiratory issues and may also affect the heart. While the research does not show a direct causal relationship, studies have found an association between incense use and an increased risk of heart disease.
A 2014 study by Pan et al. specifically examined the link between incense use and cardiovascular mortality in a cohort of 63,257 Singaporean Chinese individuals aged 45-74. The researchers found that 8% of deaths from coronary heart disease and 12% of deaths from stroke could be attributed to long-term exposure to incense smoke. This study is notable for its cohort design, which provides evidence that the incense exposure preceded the health outcomes.
The mechanisms by which incense smoke may contribute to heart disease are not fully understood, but it is thought to involve inflammation and the deposition of harmful substances in the body. Additionally, the impact of incense smoke on heart health may be influenced by other factors such as cigarette smoking, as the association between incense use and cardiovascular disease was found to be weaker in smokers.
To reduce the potential risks associated with incense burning, it is recommended to improve ventilation by opening windows and doors, use natural, plant-based incense without added chemicals, and consider smokeless or low-smoke alternatives.
