Mowing the lawn or raking leaves can make you very sick if you are allergic to pollen from grains, trees or weeds. It's a problem if you are allergic to molds, too. Keep windows and doors shut and stay inside when the pollen count or humidity is high.

Put an air conditioner or air cleaner in your house, especially in your bedroom. Be sure to clean the filter often. Dust and vacuum your home often. Take carpets and drapes out of your bedroom. Cover your mattress with a plastic cover.
