Summer brings longer days, outdoor activities, and warmer temperatures, but for many people dealing with varicose veins, the season can also bring increased discomfort and more noticeable symptoms. The combination of heat, humidity, and increased activity levels can cause your already problematic veins to become more swollen, achy, and visible than during cooler months. Understanding how summer weather affects your vascular system can help you take proactive steps to manage your symptoms and enjoy the season more comfortably.
