Spring is full of new beginnings.

Flowers are in bloom, green grass reappears, and once-barren trees become leafy and full again. Unfortunately, as many plants come back to life, spring allergies blossom as well. Make sure you avoid becoming a victim of irritating and often painful symptoms.

An estimated 36 million Americans are affected by allergic rhinitis, or hay fever, in the spring. These allergies are triggered by substances such as tree pollens, grasses, and molds, and result in symptoms ranging from itchy, watery eyes and sneezing to a runny nose, sore throat, and headaches. Luckily, you don't need to wait until summer to find relief from the misery. Here are some ways to stay bright-eyed and clearheaded all season long.

Limit exposure to the outdoors.

Close windows and use an air conditioner to keep pollen out of your home. Also, keep car windows closed when traveling.

Time your outdoor activities.

Different pollens are released at different times; for example, spring tree pollens are highest in the early morning. Find which ones trigger your symptoms and adjust your schedule accordingly. Because air pollution can worsen symptoms, do outside chores in the morning or evening when the air quality is better.

Cover up and clean up.

Wear a dust mask when doing outdoor chores, such as mowing or raking, which can stir up pollens. Change your clothes and take a shower after being outside to wash off any pollen that's collected on your skin or hair.

Don't dry clothes on an outdoor line.

Pollen and molds can accumulate on them, so stick to the clothes dryer to avoid triggering any allergic reactions.

Visit your doctor.

Several oral and nasal medications can take the edge off your symptoms, or block them before they even begin. An allergist or immunologist can help find the right medication for you.

Take a vacation.

Experts say areas near large bodies of water tend to have lower pollen counts—there was never a better excuse for hitting the beach!
