What triggers stress hives?

Can Stress Cause Hives?

Hives can also develop as a result of sun or cold exposure, infections, excessive perspiration, and emotional stress. The reason why stress seems to precipitate an outbreak of hives in many people is not completely understood but is likely related to the known effects of stress on the immune system. In many cases, the cause of hives in a given individual cannot be identified.

Hives facts

  • Hives (medically known as urticaria) are red, itchy, raised welts on the skin that appear in varying shapes and sizes; each one characteristically lasts no longer than six to 12 hours.
  • Hives are very common, and most often their cause is elusive.
  • Hives can change size rapidly and move around, disappearing in one place and reappearing in other places, often in a matter of hours.
  • Ordinary hives flare up suddenly.
  • Occasionally hives are produced by direct physical stimulation by environmental forces like heat, cold, and sunlight.
  • Treatment of hives is directed at symptom relief until the condition goes away on its own.
  • Antihistamines are the most common treatment for hives.
  • Hives typically are not associated with long-term or serious complications.
