What is an Asthma Trigger?
An asthma trigger is anything which causes the inflammation of the airways, leading to the symptoms of coughing, wheezing or shortness of breath, that you normally would associate with asthma. Your triggers can be numerous and varied. They can be in the form of an allergen or an environmental exposure to an irritant.
Common allergens at this time of year can include many of the spring pollens. Did you know that the tree pollens become active as early as the end of February? Tree and grass pollens are some of the more common allergens which trigger asthma. Also, did you know that asthma and hay fever often co-exist? Interestingly, Hay fever alone can be an independent risk factor in the development of asthma.
Some research suggests that when hay fever and asthma co-exist, treating the hay fever with nasal inhaled steroids can effectively control the asthma at the same time.
