Thunderstorm asthma

Professor Gennaro D’Amato discusses the effects and mechanisms of thunderstorm asthma during pollen season.

'Thunderstorm' asthma

Thunderstorm asthma is a particular phenotype of asthma that involves sensitisation to pollen. Outbreaks are induced usually in the first 50 minutes of a thunderstorm during pollen season, generally from March to June in Europe. To protect the airway, those with allergic asthma (to pollen) should avoid going outside before and during a thunderstorm in pollen season.
