Thunderstorm Asthma: Thunderstorms are known to cause destruction to life and property, but they are also infamous for causing thunderstorm asthma in certain cases which can lead to triggering respiratory symptoms in individuals.
The largest such event occurred in 2016 in Melbourne which caused 10000 people to be affected by it. It also caused around 10 deaths due to the same.
Let us learn about Thunderstorm Asthma and its causes, and symptoms here.
What is Thunderstorm Asthma?
Thunderstorm asthma is a type of asthma that is triggered by the bursting of pollens during thunderstorms, it causes breathing problems, runny or stuffy nose and itchy eyes.
It is mainly seen in dry and dusty areas like Australia, and Kuwait. But, it is not restricted to only these areas, it is also seen in England, Iran etc.
What causes Thunderstorm Asthma?
Thunderstorm asthma is caused due to the pollen grains that burst when they absorb moisture from the environment. Upon bursting the pollens release smaller pollen grains which can invade the respiratory system.
Due to this respiratory symptoms are triggered which have symptoms like wheezing, coughing, itchiness of the eyes and hay fever.
Thunderstorm asthma is caused mainly due to the bursting of rye grass pollen grains. The rye grass pollen grains can release up to 700 smaller pollen grains on bursting.
