The American College of Allergy, Asthma, and Immunology reports that 10 percent of the U.S. population has an allergy to exotic or household animals. Although dog and cat allergies are the most common animal-related allergy, an allergy to feathers or down can cause mild to severe asthma-like symptoms. Down feather allergies can be managed through medication and lifestyle changes.
Allergies are common when plants are in bloom and pollen is in the air. But allergies can also be caused by pets, including birds. Down feather allergies are created from bird dander known as feather dust. Feather dust comes from a certain type of bird known as a powder down. This bird has special down feathers that emit feather dust into the air.
Allergies to feather pillows are one of the most commonly reported allergies. Symptoms that include sneezing, sniffling and clearing your throat can easily ruin a good night's sleep.
