You may wonder why you get hay fever. Hay fever happens when your immune system overreacts to things like pollen. Your immune system produces antibodies that bind to cells in your nose and eyes. When you encounter the allergen again, these cells release chemicals like histamine, causing symptoms such as sneezing, itching, and watery eyes. Hay fever symptoms are usually seasonal because they're triggered by specific allergens like tree or grass pollen. If you frequently experience itchy and watery eyes, treatments that directly target the area may be most effective. It is also advisable to wear sunglasses on high pollen count days. Sunglasses which have a wraparound effect can be most beneficial to reduce pollen directly affecting the eye area. In addition, the masks we’ve all become accustomed to wearing during the pandemic can actually be beneficial for those of us who have allergy symptoms too, as well as potentially protecting against pollution."
