Burning incense can pose health risks for those with allergies and asthma

(Press-News.org) BOSTON (Oct. 24, 2024) – In many cultures, it is common to burn incense for religious and cultural practices, including meditations, celebrations and spiritual and ancestral worship. A new medically challenging case being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston warns that, for those with allergies and asthma, health problems from burning incense can be a significant risk to adults and children.

“Our patient was an 87-year-old woman with history of asthma and COPD, on oxygen therapy, who presented with unexplained shortness of breath,” says Gomeo Lam, BA, lead author on the paper. “A detailed history revealed daily incense burning. We recommended she stop burning incense, which the patient did not want to do as burning joss stick incense daily allowed her to express homage and veneration for ancestors. We then advised she use electric incense devices, which resulted in improvement of her symptoms.”

The paper points out that burning incense poses health risks including headaches, respiratory dysfunction, dermatologic sensitivity and allergic reactions. Incense fumes contain carbon, sulfur, nitrogen oxides as well as formaldehyde, and other polycyclic aromatic volatile compounds which are carcinogenic. Per gram burned, particulate matter generated from incense is 45 mg versus 10 mg from cigarettes. 

“People who burn incense may not realize that family members, including children, who are exposed to secondhand smoke, face health consequences,” says allergist Mary Lee-Wong, senior author of the study and ACAAI member. “Similar to tobacco smoke, thirdhand incense smoke may linger in furniture, clothing, and other articles, dissipating for months afterward.”

The authors point out that, besides health implications, incense combustion contributes to air pollution and can be a fire hazard. They recommend that when counseling patients who burn incense, health practitioners consider the sacred significance of incense burning, but also recognize that health risks from this practice cannot be overlooked. After screening patients for incense use, healthcare practitioners can recommend replacement with electric or aromatic vapors; simulated visuals; improved ventilation; and limiting burn time as approaches to mitigate harms and improve symptoms.

Introduction: Incense, as coils, cones, powders and sticks, is widely used for religious and cultural practices. Usage includes meditations, celebrations, deodorizations, in addition to spiritual and ancestral worship. Health problems from incense burning are numerous. 

Case Description: An 87-year-old woman with history of asthma and COPD, on oxygen therapy, presents with unexplained shortness of breath. Detailed history taking disclosed temporal relationship with incense burning. Recommendation to stop burning incense was denied as burning joss stick incense daily allows patient to express homage and veneration for ancestors. Subsequently, advice to use electric incense devices resulted in improvement of patient's symptoms.

Discussion: Burning incense poses health risks including headaches, respiratory dysfunction, dermatologic sensitivity and allergic reactions. Incense fumes contain carbon, sulfur, nitrogen oxides as well as formaldehyde, and other polycyclic aromatic volatile compounds which are carcinogenic. Per gram burned, particulate matter generated from incense is 45 mg versus 10 mg from cigarettes. Studies report family members, including children, exposed to incense burning suffer from secondhand smoke health consequences. Like tobacco smoke, thirdhand incense smoke may linger in furniture, clothing, and other articles, dissipating for months afterwards. Besides health implications, incense combustion contributes to air pollution and can be a fire hazard. Understanding the role, cultural sensitivity and sacred significance of incense burning is vital but health risks from burning incense cannot be overlooked. Screening patients for incense use, in addition to replacement with electric or aromatic vapors, simulated visuals, improved ventilation, and limiting burn time can be explored with impacted patients.
