Spring is a mixed blessing if you have seasonal allergies. Blooming plants are pretty, but you can also expect itchy eyes, a runny nose, and a scratchy throat. Thankfully, avoiding allergy triggers and taking medication can help.

If you also have asthma, they can help control that condition, too. More than half of all asthma sufferers also have allergies. Some substances, known as allergens, jump-start the immune system and trigger an asthma attack.

Tame Your Triggers
The best way to prevent an allergic asthma attack is to avoid allergens. Try these tips:

Dust mites. These bugs live in rugs and bedding. Wash your sheets and blankets in hot water every week. When cleaning, dust with a damp rag and use a filtered vacuum.

Mold. Run a dehumidifier in rooms that get damp.

Cockroaches. Keep food tightly covered. And take out the trash often. You should also wash dishes and wipe down the countertops and stove right after a meal.

Pet dander. Keep dogs and cats out of your bedroom and vacuum regularly. And remember to wash your hands after touching a pet.

Pollen. Stay indoors in the morning, when pollen levels tend to be highest. Wash your hair before bed. Close your windows and use air conditioning, if you can.

Take Your Medicine
Taking your asthma medicine can help keep your allergies— and asthma—under control. But you may need more than one kind. A long-term-control medicine helps make your lungs less sensitive to allergens and irritants. You have to take it every day. The other medication is only for when you have symptoms.

If you’re using your fast-acting medicine every day or several times a day, talk with your doctor.
