Dust mites are a common indoor trigger for people with allergies and asthma. They thrive in warm, humid spaces and are most often found in bedding, upholstered furniture, carpets and soft toys.
Symptoms can resemble seasonal allergies: sneezing, congestion, itchy eyes, coughing or worsening asthma. The mites themselves are too small to see easily; allergic reactions are generally caused by proteins in their waste and body fragments.
Regularly washing sheets, pillowcases and blankets in hot water is among the most practical steps households can take. Allergy-proof mattress and pillow covers can also create a barrier between sleepers and a major dust-mite habitat.
Reducing indoor humidity, vacuuming with a high-efficiency filter and minimizing clutter that collects dust can help. Curtains, rugs and upholstered furniture may require more frequent cleaning when allergy symptoms are persistent.
People with recurring symptoms should discuss them with a health professional, particularly if breathing problems, wheezing or sleep disruptions are involved. Cleaning can reduce exposure, but it does not replace medical evaluation or an asthma treatment plan.
