Allergic reactions from sunlight exposure, insect stings or bites, chemicals from certain foods, or medications cause histamine release from specialized skin cells. Hives are actually the result of blood plasma that leaks out of small blood vessels in the skin.

What are hives? They’re not dangerous, but they are a reaction. An easy way to tell that your skin is experiencing physical urticarial, is if the hives only appear on skin that has been exposed or stimulated by said irritants. This could be caused from a wide variety of factors including cold, heat, sun exposure, vibration pressure, sweating and exercise, and usually appear within one hour after exposure or irritation. Physical urticarial, also known as hives caused by the direct stimulation of the skin, occur where skin has been irritated. After going for a run or attending a yoga class have you ever noticed red, sometimes itchy bumps on your skin? No, you’re not allergic to exercise, but you could be breaking out in hives.
