If you are allergic to pollen, make note of the local pollen forecast, which you can easily check online. During these peak pollen times, close the windows of your house to make sure the allergens don't get in.

And if you like to exercise outside, timing is everything. "Try not to run early in the morning, when pollen levels are high," says Stokes. To prevent the allergens from getting into your body, you can try to exercise with a mask that covers your nose and mouth, and goggles to protect your eyes. Taking antihistamines 30 to 60 minutes before you exercise outside can also help, adds Riedl. Choosing to exercise in the city instead of nature probably won't make much of a difference. You may be exposed to less pollen if you work out in the inner city compared with the woods, but you will breathe in more mold particles; and the city won't save you completely from pollen because the allergens can travel for miles.
