Your 6-Step Guide to Preventing Spring Allergies

Spring is here, which means spring allergies have also arrived. Here’s how to stop them before they start.

Sure, spring can be beautiful, with trees and flowers in full bloom, but if you have allergies all those green leaves and flowers can also signal the start of one of the most challenging times of the year for you.

“Allergies have been shown to affect patients’ quality of life, usually through increased fatigue, irritability and sometimes increased anxiety or depression,” says Elizabeth Ference, MD, assistant professor of clinical otolaryngology at the Keck School of Medicine of USC and an otolaryngologist at Keck Medicine of USC.

However, by following a few key pointers, you can limit the negative effects of allergies. Here’s how to stop spring allergies — also called allergic rhinitis or hay fever — in their tracks.

1. Start taking allergy meds early

One of the most important steps you can take if you know you’re allergic to pollen, is to start taking an over-the-counter antihistamine or using a nasal spray before your symptoms hit. That’s because allergies are easier to prevent than to treat. In Southern California, spring allergy season typically starts in February with tree pollens, including oak and walnut trees, and lasts through June when grass pollens hit their peak.

2. Move your workout indoors

Yes, the beautiful weather combined with longer days may tempt you to get outdoors, but if you have allergies an outdoor workout might not be the best option. Instead of a morning run, you might consider a yoga or spin class. If you really don’t want to give up your daily jog, it’s better to wait until the afternoon or early evening when pollen counts tend to be lower.

3. Turn on the air conditioner

Keeping your windows closed will prevent pollen and other outdoor allergens from getting into your home. Keep the windows up in your car, too. If you are very sensitive, run a high-efficiency particulate air (HEPA) filter in your home to reduce the allergens in the air.

4. Keep your house clean

Pollen loves to stick to fabric and carpets, so it’s essential you vacuum and dust regularly to keep pollen and other allergens to a minimum.

5. Shower at night

On days you’ve been outdoors, it’s a smart idea to shower and shampoo your hair at night to wash off any pollen on your body. Be sure to wash your clothes too.

6. Monitor daily pollen counts

On days with a high pollen count, it’s especially important for you to follow all the above steps. Tune into the morning weather report or sign up for an allergy alert app to receive daily notifications.

If you are still experiencing symptoms, ask your doctor if allergy shots (allergen immunotherapy) might be right for you.
