A dust allergy is your immune system reacting to proteins found in dust-mite debris. Indoors, it usually shows up as a mix of respiratory and skin symptoms.
If sneezing or congestion hits the moment you wake up, or while you clean, dust is very likely the trigger.
Sweeping, vacuuming or shaking out bedsheets stirs particles into the air, which often leads to sudden dry coughing fits.
In more severe cases dust-mite allergy triggers asthma-like symptoms — wheezing, chest tightness and shortness of breath.
Sudden itching or a crawling feeling at night in bed is a strong indicator of mites in the mattress or pillows.
Prolonged contact with mite-infested fabrics can cause eczema flare-ups, redness and clusters of small itchy bumps.
