What should you know about avoiding seasonal allergy allergens?

Seasonal allergies, also called allergic rhinitis or hay fever, happen when the immune system reacts to airborne allergens such as pollen. The nose may become itchy, blocked or runny, with repeated sneezing and drainage down the throat. Eye symptoms can occur as allergic conjunctivitis. Some people notice cough or asthma symptoms when their airways are also sensitive. Avoidance lowers contact with the trigger but may not remove every symptom.

Your pattern matters: note the season, places, outdoor activities and time of day linked with symptoms. This can help identify whether pollen or another airborne irritant is involved.

Keep doors and windows closed when pollen is high, and use indoor cooling or filtration if available. Wear wraparound glasses outdoors, avoid rubbing your eyes, and shower or change clothes after outdoor activities. Ask someone else to cut grass when possible. Dry clothes indoors during heavy pollen periods because fabric can collect allergens. Clean floors and surfaces regularly, and avoid bringing outdoor pollen into the bedroom. A pharmacist or clinician can advise on nasal sprays, antihistamines or other treatment suited to your health and medicines.

Get urgent help for severe breathing difficulty, wheezing that is not settling, swelling of the lips or tongue, faintness or blue lips. Arrange a review when symptoms interfere with sleep, work or exercise, when sinus pressure persists, or when a child has recurrent ear symptoms. Persistent cough or blocked nose may need assessment for asthma, sinusitis or another cause.

Ask which allergen is most likely, whether testing would help, and how to use a nasal spray or antihistamine correctly. Discuss an asthma plan if pollen brings chest tightness or wheeze, and ask how to protect sleep during the allergy season.
