Extensive dairy pastures mean high grass pollen. Common symptoms include sneezing, runny or blocked nose, itchy and watery eyes, and an itchy throat. During prolonged dry spells, symptoms may be more persistent. The urban environment means pollution can exacerbate symptoms, particularly in built-up areas.
