May 15 marked the start of the festival of Lag BaOmer, a joyful celebration that blends Jewish tradition with the community. However, for individuals with asthma and other respiratory conditions, the tradition of lighting bonfires poses a serious health risk—especially for vulnerable populations.
This year, Lag BaOmer coincided with Asthma Awareness Week, offering an opportunity to raise awareness about the dangers of smoke exposure and how to mitigate them. Dr. Jasmin Khatib-Atallah, a pulmonary specialist, head of the Severe Asthma Clinic, and deputy director of the Pulmonary Institute at Rambam Health Care Campus (Rambam), emphasizes the health risks associated with bonfire smoke and shares ways to stay safe.
Bonfire smoke contains harmful particles and gases that can worsen asthma symptoms and cause breathing difficulties. “Even brief exposure can cause serious complications—especially in young children, older adults, and pregnant women with asthma,” explains Khatib-Atallah. “Research shows a 30% increase in emergency room visits and hospitalizations due to smoke-related asthma flare-ups.”
Asthma is a chronic condition caused by a combination of genetic and environmental factors, leading to inflammation and heightened sensitivity in the bronchial tubes and making them especially reactive to smoke, dust, cold air, and other irritants. Common triggers—such as air pollution, physical exertion, or allergens—can spark asthma attacks. Symptoms include shortness of breath, chest tightness, coughing, and wheezing, and are typically managed with inhalers and medications.
Smoke exposure can lead to increased use of oral or intravenous steroids and may trigger a rapid decline in lung function—often appearing within an hour and lasting for several days. Among those most at risk are children under age 5 and adults over 65. Additionally, pregnant women with asthma face an 18% increased risk of preterm birth. Low birth weight is also a possible complication.
To reduce the health risks associated with bonfire smoke, individuals—especially those with asthma—should take several precautions: stay as far away from bonfires as possible, as clean air significantly lowers the risk of respiratory issues and keep windows closed to prevent smoke from entering indoor spaces. Asthmatics should carry a rescue inhaler for immediate symptom relief. If exposure is unavoidable, consult a pulmonologist in advance and consider using a preventive inhaler. Wearing an N95 or other filtered face mask can also help reduce inhalation of harmful particles. Avoid physical activity near bonfire smoke, since increased air intake can worsen symptoms by drawing more pollutants into the lungs.
Consult with a physician if you experience severe breathing difficulties, an increased reliance on inhalers, persistent wheezing, chest tightness, or unexplained fatigue.
Bonfires are a beautiful tradition but we urge the public—especially those with chronic lung conditions—to be aware of the risks.
