Allergy season is upon us, bringing with it runny noses, itchy eyes and sneezing. Climate change is leading to longer and more intense allergy seasons. The good news is that treatments for seasonal allergies have become more effective in recent years. Pollen trackers, like the one maintained by the American Academy of Allergy Asthma and Immunology, can help people limit exposure. Experts also recommend masks, over-the-counter medications and talking to a doctor if symptoms start impacting sleep, school or work.
