Itchy, Bumpy, Rashy: Your summer skin guide

When the summer sun shows up in the Midwest, shedding layers and heading outside is only natural. But more time outdoors and more exposed skin, can also raise the risk of hives, rashes and other mysterious bumps. These uncomfortable issues can quickly take the fun out of a family hike or a day at the beach. “Being aware is the best thing you can do,” said Dr. Elizabeth Ender, allergist. “Recognizing allergic reactions and understanding what’s triggering them, is key to proper treatment and prevention.” One surprising allergic culprit? Pollinating grass. “Grass allergy is one of the most common issues I see,” said Ender. “People come in with hives on their legs or feet, and don’t realize they are related to their seasonal allergies.” Other causes are sneakier. Some react to sunlight itself, especially when combined with makeup or sunscreen. “Those are rare, but they happen,” said Ender. “I often see it early in the summer, when people are just starting to spend more time outside.” Insect bites are another problem. Skeeter syndrome, for example, causes intense swelling or irritation from mosquito bites, especially in kids. Fortunately, it usually improves with age and repeated exposure. Other potential triggers include pet saliva, poison ivy, sweat, certain skin products or infections, such as folliculitis or swimmer’s itch. Some reactions are delayed, like eczema flaring up after sun exposure or contact with specific plants. “Poison ivy causes a delayed hypersensitivity reaction,” said Ender. “Instead of showing up right away, it takes time, because it’s driven by a different part of the immune system.” Heat can also cause confusion. “People may think they have an allergy, but it’s just heat rash,” said Ender. These prickly, bumpy rashes tend to show up where sweat collects, like armpits or skin folds. Hives, on the other hand, which can also sometimes be triggered by sweat or heat, are extremely itchy, appear quickly and fade within a day. Some symptoms should never be ignored. “If a reaction is immediate and severe, especially if it affects breathing or causes throat swelling, get care right away,” said Ender. “Even mild reactions that worsen over time, like open sores or spreading rashes, should be checked out.” When not sure what’s going on with skin, talk to a doctor. “It can be hard to tell the difference between an allergic reaction and another skin issue,” said Ender. “Your primary care provider can help figure out whether you need to see an allergist or a dermatologist.” And don’t underestimate the power of recording symptoms. “The most important tool we have is a good history,” said Ender. “If you ever experience any skin issues, write down what you were doing, where you were, and any products or animals you came into contact with. It makes a huge difference. Also, if you can, take a few pictures. You’d be surprised at how often a rash resolves right before you are seen by your doctor.” A little observation and the right care, can help make the most of the sunshine.
