Winter allergies are sometimes called seasonal allergies. KeepKidsHealth.com points out that allergies are unrecognized due to colds and flus also being common during the winter months. Symptoms of common allergies in the winter can include a runny nose, water eyes, sneezing and a cough. Certain allergens such as molds can be present year-round but are more prominent during the winter months.
Mold and Mildew Spores
Mold and mildew spores are a common source of winter allergies, states the University of California Berkeley. When the climate becomes colder, people are more likely to spend time indoors, increasing their exposure to the mold spores. These allergens can be spread throughout the air when the home heating unit is run. Mold and mildew can develop in warm and wet areas in the home, including the basement, bathroom and water-damaged areas. Holiday trees, also called Christmas trees, are often brought indoors during the winter months for holiday celebrations. KeepKidsHealthy.com explains that mold can already be present or grow on the tree once it is indoors.
Microscopic Bugs
Microscopic bugs called dust mites are found throughout homes. These tiny beings feed on plant and animal particles, including skin flakes, states the University of California Berkeley. The fecal matter from the bugs can trigger allergic reactions and increased asthma flare-ups. Dust mite allergies can increase in the winter months because windows are kept closed and the same household air is recirculated throughout the house allowing the mites to thrive and spread. Similar to mold, dust mites can thrive in holiday decor like trees and other ornaments that may have been stored through the year, states KeepKidsHealthy.com.
Pet Proximity
Pet allergies are most likely present year-round, but the winter months may increase the adverse effects of dander exposure. Pets are more likely to be kept indoors due to the cold climate, torturing allergic owners, states KeepKidsHealthy.com. Allergy-triggering dander is found in pet skin cells and saliva.
