If you break out in a red, itchy rash every time you exercise, you may wonder what it is and how can you avoid it. Your rash may be physical urticaria, a type of hives, or urticaria, that develops from physical stimulation. It occurs when your immune system reacts to something that affects your skin, such as sweat, temperature changes or sunlight. Here's more information about hives in general, how physical urticaria develops and what you can do to keep from breaking out when you work out.
What Are Hives and Physical Urticaria?
Hives are allergic reactions or sensitivities that develop when your body's immune system encounters something that causes it to react in self-defense. The immune system attacks the invader by a releasing chemical called histamine into your bloodstream to control or get rid of it. The symptoms of hives can vary from small, skin-colored patches of itchy skin to large, reddened welts, depending on the severity of the reaction. Physical urticaria is one type of hives.
Physical hives develops when something aggravates your skin, such as your clothing rubbing against your skin or your body's temperature becoming too warm or too cold. Fluid builds up in the affected skin, causing it to develop small itchy, blister-like welts or bumps that appear red or white. Your skin may even swell up from the fluid buildup. The skin condition can go away within 24-48 hours, or it can continue to bother you for up to six weeks.
Like other types of hives, physical urticaria can return often. To stop the outbreaks, it's important that you seek treatment from a dermatology or allergy specialist.
How Do You Stop Breaking Out When You Exercise?
A specialist may prescribe antihistamine medications or allergy shots to keep your immune system in check when you exercise. The medications suppress the histamines that create your hive symptoms. You may also need to change your exercise routine to help control your outbreaks.
Figuring out what triggers your physical hives in the first place may be one of the best ways to stop or control them. For instance, if you tend to break out when you run outdoors in direct sunlight, you may want to run indoors with treadmill or outdoors in the evening instead. The sunlight and heat of your body may be triggers for your condition. Cool indoor air may help control or prevent it. Once you find the triggers for your physical urticaria, you may have a better chance of keeping it at bay.
