Symptoms from these are frequently worse in the winter when the house is closed up. Mold spores cause at least as many allergy problems as pollens. Molds are present all year long and grow outdoors and indoors. Dead leaves and farm areas are common sources for outdoor molds. Indoor plants, old books, bathrooms, and damp areas are common sources of indoor mold growth.
Molds are also common in foods, such as cheese and fermented beverages.
Rid the home of indoor plants and other sources of mildew. Change feather pillows, woolen blankets and woolen clothing to cotton or synthetic materials. Enclose mattress, box springs and pillows in plastic barrier cloth. Use antihistamines and decongestants as necessary and as tolerated. Sleep with the head of the bed tilted upwards.
