Dust allergy is one of the most common triggers of asthma. If you are allergic to dust the following symptoms are noticed on exposure to dust:
For many individuals, suffering from asthma dust often triggers an attack of asthma. This could be due to dusts acting as a trigger from irritation of the nerve endings lining the airway tubes, as well as nostrils or an allergic reaction to different components of dust. Most of the dust particles are filtered and kept in the nose and sinuses and are thus prevented from entering the lower airway. Once trapped in the nose, sneezing is triggered resulting in forceful expulsion of dust particles. Sudden production of mucus is one way to wash away the dust particles trapped in the nasal passage. Further entry of dust particles is reduced by blockage of the nose due to swelling of the mucosal lining. Entry of dust particles in the upper airway and sinuses may induce a contraction of the lower airway leading to tightness of chest in those with asthma.
How to control symptoms due to dust allergy?
Avoid carpet floors if possible.
Reduce unnecessary cushions on furniture.
Reduce the number of stuffed toys in your child’s room.
Avoid Venetian blinds.
Keep book shelves clean and free of dust.
There are many measures you need to take in order to achieve a good control of asthma. Remember that asthma symptoms occur when the external environment forces the airway to contract (shrink). This is because the airway diameter can, at any time, based upon the exposure to offending agents, can change – this is in a way eliciting the protective mechanism to reduce the entry of offending agents into the airway.
