Q. WHAT IS THUN­DER­STORM ASTHMA?

Good Health Choices - - Be Informed -

A. Thun­der­storm asthma is thought to be trig­gered by thun­der­storms that have rapid changes in wind, tem­per­a­ture and hu­mid­ity. These changes can cause pollen grains to ab­sorb mois­ture, burst open and re­lease large amounts of small pollen-al­ler­gen par­ti­cles that can pen­e­trate deep into the small air­ways of the lung. Peo­ple af­fected by thun­der­storm asthma have usu­ally had se­vere hay fever and have been found to be al­ler­gic

to rye­grass pollen.
