Incense smoke can cause coughing and respiratory issues
Incense smoke contains particulate matter, gas products, and organic compounds that can be easily inhaled and may have negative health outcomes. The particulate matter in incense smoke is associated with an increased risk of respiratory problems and cardiovascular diseases. Ultrafine particles, in particular, have been linked to higher rates of hospital admissions, morbidity, and mortality due to respiratory issues.
Several studies have found a correlation between incense burning and respiratory issues such as coughing, phlegm, and dyspnea. For example, a study of temple workers in Taiwan found that they had higher rates of coughing, phlegm, and dyspnea than church workers, even after controlling for potential confounders. Another study in Hong Kong found that children exposed to incense burning were more likely to have respiratory issues such as coughing, wheezing, and asthma. However, it is important to note that not all studies have found a significant association between incense burning and respiratory problems.
The composition of incense smoke includes harmful constituents and deposition capacity in the body, which can lead to toxicities and adverse health effects. The smoke contains reactive oxygen species that can cause oxidative stress and associated inflammation, contributing to various unfavorable responses. Additionally, incense smoke has been linked to an increased risk of heart disease and issues with brain health in older adults.
The fragrance materials in incense are generally derived from plant extracts, with many types of fragrances originating from natural sources such as sage, resins, oils, and wood. However, incense makers also add synthetic materials to enhance their fragrance, ability to burn, and hold blend materials together, which can trigger allergic reactions in some individuals.

Asthma and incense burning: a study on adolescents in Taiwan
Incense burning is a popular cultural and religious practice, but the effects of incense smoke on lung function are not entirely clear. A study conducted in Taiwan investigated the association between lung function and incense burning exposure in adolescents who participated in a mass asthma-screening program. The study analyzed the lung function data of 5010 students aged 14-16 years in northern Taiwan, of whom 70.6% were exposed to incense smoke at home. The results of this study suggested that incense burning was associated with an increased risk of respiratory diseases and symptoms such as asthma, cough, and wheezing.
Another study by Wang et al. in 2011 specifically looked at the association between incense burning and asthma in children. They found that incense smoke exposure during pregnancy is a risk factor for elevated serum immunoglobulin E (IgE) in human umbilical cord blood, which is linked to the development of asthma and allergies in children.
The potential health risks of incense burning are not limited to respiratory issues. A study conducted in temples in central Taiwan found significantly increased concentrations of different particulate matter (PM) fractions during heavy incense burning episodes. Incense burning generates larger quantities of particulate matter ≤ 2.5 μm in diameter, which can remain in the air for hours and penetrate deeper into the lungs. Exposure to incense smoke has been associated with eye, throat, and skin irritation, as well as neurological problems such as headaches, forgetfulness, and difficulty concentrating.
While the studies suggest a correlation between incense burning and adverse health effects, it is important to note that the precise mechanisms and causative relationships are still being investigated. The composition of incense varies, and the health impact may depend on the specific ingredients and the duration and concentration of exposure. It is recommended that individuals with asthma or other respiratory issues consider alternatives to commercial incense, such as loose grain incense or natural, fragrance-free options, to reduce potential negative impacts on their health.

Health risks of incense: respiratory dysfunction and allergic reactions
Burning incense is a popular practice across the world, with a long history of use in religious and cultural contexts. However, despite its widespread use and pleasant aroma, incense smoke poses several health risks, particularly for those with respiratory issues and allergies.
Respiratory dysfunction is a significant concern associated with incense burning. Incense smoke contains particulate matter, including volatile organic compounds such as benzene, aldehydes, and polycyclic aromatic hydrocarbons. These compounds can be easily inhaled and have been linked to respiratory diseases, including asthma. The particulate matter in incense smoke can induce oxidative stress, disrupting tight junctions and impairing bronchial epithelial barrier integrity, leading to airway hyperresponsiveness. This can result in impaired lung function, as evidenced by increased airway hyperresponsiveness (AHR) and the recruitment of inflammatory macrophages in the lungs.
In addition to respiratory issues, the practice of burning incense has been associated with allergic reactions and dermatological sensitivity. The smoke contains various irritants and allergens, including carbon, sulfur, nitrogen oxides, and formaldehyde. These substances can trigger allergic responses, particularly in individuals with pre-existing allergies or asthma.
The health risks of incense burning are not limited to direct exposure. Similar to tobacco smoke, thirdhand incense smoke can linger on furniture, clothing, and other household items for months, affecting family members, including children, through secondhand smoke exposure.
While the benefits of incense burning in cultural and religious practices are acknowledged, it is important to be aware of the potential health hazards. Reducing incense use, improving ventilation during and after burning, and exploring alternative methods of fragrance delivery can help mitigate these risks.

Incense alternatives for asthmatics: electric incense, loose grain incense, etc
Burning incense can be harmful to people with asthma. The smoke released from burning incense contains particulate matter that can be easily inhaled and may have negative health consequences. In many cases, the smoke from burning incense can exacerbate asthma, causing coughing fits and making it hard to breathe.
If you have asthma and want to use incense, there are a few alternatives you can try. One option is to use loose grain incense, which can be mixed with water, heated over a tealight burner, and produce a scent without the smoke. Another option is to place frankincense crystals or other resins in a bowl with water and heat them over a heat source. You can also try using natural, fragrance-free incenses made from dried plant materials like sage or sweetgrass, which some people report having no reaction to.
If you're looking for an electric alternative, you can try using essential oils with a diffuser or making your own room spray using a carrier oil. You can also try using electric candles, which don't produce smoke but can still be used in rituals or meditation practices.
Finally, if you're using incense to represent the element of air, you can substitute it with symbolic items like feathers or a fan.
