7 Surprising Triggers of Lung Trouble
Over the years there have been scattered reports of fireworks causing asthma attacks. In one especially chilling incident, detailed in 2000 in Annals of Allergy, Asthma & Immunology, a 9-year-old girl with moderate asthma suffered a severe asthma attack and died after playing with sparklers at a Fourth of July picnic.
When lit, Roman candles, bottle rockets, sparklers, and other fireworks release numerous chemicals, including sulfur dioxide, which can exacerbate asthma when inhaled in concentrated amounts.
In large-scale firework displays, even the smoky fallout, which contains barium aerosols, could potentially exacerbate asthma, a 2008 study suggested.
