Typical symptoms include blocked nose, especially at night and in the morning after exposure to the mites that live in our bedding. 

Year-round disease

People suffering from house dust mite allergy often feel tired and fatigued. They sleep restlessly and are often woken by breathing difficulties. Many also snore and experience a dry mouth and throat, or they wake up coughing.

Unlike pollen allergies, which are seasonal, house dust mites are present all year round, making them hard to avoid.
