Winter is typically not considered allergy season, yet flare-ups occur just as commonly for people who suffer from indoor allergies as any other season. The Academy of Allergy, Asthma and Immunity reports as many as 50 million Americans suffer from allergies. Allergy sufferers suffer from the condition year round showing symptoms of itchy eyes, sneezing, congestion and fatigue. Symptoms have similarities to the common cold. Unlike the common cold, symptoms occur all at once and continue while exposure to allergens is present reports the Cleveland Clinic. Winter allergies can result from several indoor pollutants that become airborne once a home's furnace system is turned on, as well as decreased ventilation during the cold season.
Dust Mites
Dust mites are microscopic bugs which feed on plant and animal particles. They cannot be seen with the naked eye, explains the Asthma and Allergy Foundation of America. The foundation adds nearly 20 million Americans suffer from dust mite allergy. Dust might droppings contain proteins which cause asthma symptoms to occur, explains Berkley University. Dust mites are found throughout a home, but will most likely exist in humid areas or where large amounts of human dander, or dry skin flakes, are found, such as in the bedroom, suggests the university.
Reduce dust mites during the winter season, as well as year round, by placing plastic covers over pillows and mattresses. Decrease the amount of stuffed animals in a home, or wash the toys in hot water weekly suggests Berkley University. Vacuuming once or twice a week as well as keeping indoor humidity at 50 percent decreases dust mite growth.
Mold
Mold is made up of allergy-causing spores which cause allergies. The spores are commonly found in high humid areas such as basements, bathrooms and kitchens. Water-damage also causes mold to grow. Many people use vaporizers during the winter cold and flu season. Ensure the vaporizers are properly cleaned by changing water daily, and cleaning the device with bleach weekly. Place a dehumidifier in humid rooms to reduce mold growth. Remove moldy firewood stored near indoor fireplaces. Mold often grows on live plants; limit the home to only a few houseplants suggests the Asthma and Allergy Foundation of America.
Pets
Many people believe pet fur causes allergies; however, the allergen actually lies in the protein dander from a pet's skin. Berkley University reports most people who suffer from allergens have reactions to the cat and dog dander as well as dried saliva.
Due to cold weather and snow, pets spend more time indoors during the winter. Keep pets in one area of the home, and avoid allowing them to sleep in the bedroom, suggests the Asthma and Allergy Foundation of America. Giving pets weekly baths will decrease the amount of dander and dried saliva on the pet.
