Asthma can get triggered due to materials, conditions or activities that certainly worsen the asthma symptoms or cause an asthma flare-up. The allergy triggers which leads to asthma include but are not limited to dust mites, animal dander (especially from cats and dogs), mould spores which get worse at certain times of the years, pollen from grass, weeds, and trees, workplace substances such as latex, wood dust or flour. In order to avoid an asthma attack, it is important for the sufferer to determine the triggers in their case. However, in the case of multiple symptoms, it certainly gets difficult to avoid them all.
