10 Causes of Urticaria
Cause #7: Exercise
Exercise-induced urticaria is a condition in which the body responds to intense exercise with hives. In many people, they will experience other allergic responses in addition to the hives when they are exercising.
This can occur because the body of someone struggling with this problem will produce histamine while they are exercising. Histamine is the compound that is responsible for the majority of these allergic reactions; this is why over-the-counter antihistamines are the main drugs used to help manage mild-to-moderate allergies.
