Allergens can trigger the various hay fever symptoms by attaching themselves through the air to clothes and furniture. Every time someone becomes exposed to these garments and furniture around the home, they can initiate an allergic reaction. If you have pets they can attract grass or ragweed pollen and transfer them to the furniture. The best way to prevent Hay fever reaction is to take off clothes before entering the bedroom. Changing inside the bedroom will transfer the outside allergens attached to your clothes into the area where you sleep. Various combat products are available around the house, which make it easier to prevent the symptoms such as pet shampoos, Allergy detergents and anti allergy sprays
