Seasonal allergies occur when a person's immune system overreacts to allergens such as pollen, dust, and mould. Symptoms primarily affect the membrane lining the nose, leading to allergic rhinitis, or the membrane of the eyelids and the surface of the eyes (conjunctiva), resulting in allergic conjunctivitis. While there are numerous medications available to treat seasonal allergies, given below are seven strategies to help prevent them. 1. AntihistaminesAntihistamines are medications that help alleviate allergy symptoms by blocking histamines, the chemicals responsible for triggering allergic reactions. They can reduce symptoms such as sneezing, itching, and a runny nose. Common over-the-counter antihistamines include loratadine (Claritin), cetirizine (Zyrtec), and diphenhydramine (Benadryl). It’s essential to choose a non-drowsy formula if you need to maintain alertness during the day.2. Saline Nasal RinseA saline nasal rinse, often performed using a neti pot or a squeeze bottle, can provide immediate relief from nasal congestion by flushing out mucus, allergens, and irritants from the nasal passages. This simple solution of salt and water helps to moisturize the nasal membranes and can reduce inflammation. It's especially beneficial during peak allergy seasons or after exposure to allergens.3. Eye DropsAntihistamine eye drops are effective for treating itchy, watery eyes caused by seasonal allergies. These drops work directly on the conjunctiva to block histamines and alleviate symptoms. Options include ketotifen (Zaditor) and olopatadine (Pataday). For those with severe symptoms, prescription eye drops may be recommended by a healthcare provider.4. HEPA FiltersHigh-Efficiency Particulate Air (HEPA) filters are designed to capture small particles from the air, including pollen, dust mites, pet dander, and mold spores. Installing HEPA filters in your home, particularly in air purifiers and HVAC systems, can significantly improve indoor air quality. Regularly changing these filters ensures optimal performance and continued allergen reduction.5. Nasal CorticosteroidsNasal corticosteroids, available as nasal sprays, help reduce inflammation in the nasal passages and alleviate symptoms such as congestion, sneezing, and nasal irritation. Common options include fluticasone (Flonase) and budesonide (Rhinocort). For best results, they should be used regularly, even during times when symptoms are not present, as they take a few days to reach their full effect.6. Avoiding Outdoor ExposureTo minimize allergy symptoms, it's advisable to stay indoors during high pollen or pollution days. Keeping windows closed and using air conditioning can help filter out allergens. If you need to go outside, try to do so early in the morning when pollen levels are typically lower, and consider wearing sunglasses to protect your eyes from airborne allergens.7. Home RemediesIn addition to conventional treatments, several home remedies may help alleviate allergy symptoms. Local honey is believed to help build immunity to local pollen, while herbal supplements like butterbur and quercetin may offer additional relief. Acupuncture has also been suggested as a complementary treatment for allergies, potentially helping to reduce symptoms through the body’s natural healing processes. Always consult with a healthcare provider before starting new remedies or supplements.
