The best way to control your symptoms is to avoid being exposed to the allergens that trigger them.
If you have hay fever, during days or seasons when airborne allergens are high:
• Stay indoors and close the windows.
• Use an air conditioner in your home and car.
• Avoid using fans that draw in air from outdoors.
• Don't hang laundry outside to dry.
• Bathe or shower and change your clothes after being outside.
• Use a HEPA air filter in your bedroom.
If you have year-round allergies:
• Cover your pillows and mattress with dust mite covers.
• Remove carpet and install tile or hardwood floors. Use area rugs and wash them often in very hot water.
• Use blinds instead of curtains.
• Keep pets out of the bedroom.
• Use a HEPA filter on your vacuum.
• Use an air purifier.
• Wash bedding and toys, such as stuffed animals, in very hot water once a week.
There is evidence to suggest that exposure to infections, farm animals, and even domestic pets (like cats and dogs) during infancy and early childhood may reduce the risk of developing allergic rhinitis later in life. One study even suggest that premature babies have a lower risk of allergic rhinitis because of earlier exposure to pathogens.
