A stress rash is a form of hives that occurs when excessive stress causes your body to release more of the hormone cortisol. Cortisol controls inflammation and makes hives more common.
Hives can also occur as a result of an allergic reaction, exposure to hot or cold temperatures, or pressure or scratching of the skin. Usually hives last from a few minutes to a few days. To ease your symptoms, you can apply a cold compress or take over-the-counter antihistamines.
However, if hives or stress rashes persist for more than 2 days or begin to spread, it is best to contact your doctor for advice.
