Having asthma might be a burden for some because of its episodic nature. Exposure to certain elements may exacerbate the condition.
Common triggers may include: the presence of cigarette smoke, too much anxiety and stress, an ongoing viral or bacterial infection, strong scents like perfumes and colognes, air pollution, changes in the weather or quality of air.
There may be other factors called as allergic triggers like: the presence of dust mites or pollen, hair from pets or vermin, and molds.
Asthma may be triggered in more ways than one and appears to be different from person-to-person. Knowing what triggers your asthma may enable you to plan ahead to avoid it and keeping the symptoms from getting worse.
