context_page_description: Thunderstorm asthma is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm. It has been proposed that during a thunderstorm, pollen grains can absorb moisture and then burst into much smaller fragments with these fragments being easily dispersed by wind. While larger pollen grains are usually filtered by hairs in the nose, the smaller pollen fragments are able to pass through and enter the lungs, triggering the asthma attack.
