While allergies affect people everywhere, some US cities are especially tough. The Asthma and Allergy Foundation has ranked the top 10 worst cities in the US for those with allergies. The cities were ranked based on pollen levels, medicine use, and allergist access. The top 10 worst cities for people with allergies are Wichita, New Orleans, Oklahoma City, Tulsa, Memphis, Little Rock, Raleigh, Richmond, Greenville, and Greensboro. Experts say allergy seasons are starting earlier, lasting longer, and hitting harder. Prescription fills for allergy medications are higher than they've been in six years. Climate change plays a big role. Fewer frost days mean longer periods of plant growth and pollen release, especially in the Southeast, Midwest, and Mid-Atlantic. Air pollution also worsens symptoms. Urban heat, car emissions, and trapped allergens in valleys or low areas can all increase breathing difficulties during peak seasons. To treat allergies, start with the basics: antihistamines, nasal steroid sprays, and decongestants. Different medications work best depending on the severity and frequency of symptoms. For best results, speak with a healthcare provider before starting any medication. The right plan depends on your symptoms, history, and overall health needs.
