A good way to avoid allergies is to know what triggers yours. If you've had allergy tests, then you probably know that a certain tree or mold will cause a flare-up. If not, start keeping a list. Write down or make a note in your cell phone what lake you passed by or what field you were hiking through when you had an allergy attack. Location, air quality, time of day and the weather are all good factors to note.

"Most people agree that pollen is most irritating when it is dry and windy, which is most likely early afternoon," said Robert del Junco, medical director of the Nasal & Sinus Center at St. Joseph Hospital in Orange, Calif., according to Fox News.

"Pollen count is highest between 5 a.m. and 10 a.m., and again at dusk, so plan your workouts for other times of the day when pollen levels are lower," said Tonya Winders, CEO of the Allergy and Asthma Network, according to Fox News.

The perfect time for your run? Right after a rainstorm. The rain washes the pollen from the air, so pollen counts are lower after it rains. "It tends to be damper outside in the early morning and in the evenings," del Junco told Fox News.

You can check pollen count and air quality when you check the temperature on The Weather Channel or with The Weather Channel's Allergy Tracker. "If you go out during high-pollen times, you can wear a face mask designed to filter out pollens," Winders told Fox News.

Use allergy medications as prescribed by your doctor and be careful when using over-the-counter allergy medications. "You may experience low blood pressure and heart palpitations, as well as occasional periods where it feels like your heart is racing," del Junco told Fox News.

Other suggestions are to strip off your clothing as soon as you get indoors, take a shower and use a saline nasal irrigation system (like a NetiPot) to rinse pollen from your nose.
