An October 2024 study by Gomeo Lam, BA, and others, published in the Annals of Allergy Asthma & Immunology said,

  • “Our patient was an 87-year-old woman with history of asthma and COPD, on oxygen therapy, who presented with unexplained shortness of breath,”

  • “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.”

  • “People who burn incense may not realize that family members, including children, who are exposed to secondhand smoke, face health consequences,”

  • “Similar to tobacco smoke, thirdhand incense smoke may linger in furniture, clothing, and other articles, dissipating for months afterward.”
