What the Research Says About Hives and Stress
Yes, stress can be linked to hives, but it is rarely the only cause. Many people with chronic urticaria report that flares follow stressful periods, and studies have found higher stress and anxiety levels among people with the condition. Stress seems more likely to worsen hives than to create them from nothing.
What the Evidence Shows
Observational studies connect stressful life events with the onset of chronic hives, and many patients report worse symptoms during stress. However, it is hard to prove cause and effect, because hives themselves are stressful. Researchers think stress hormones and neuropeptides may influence mast cells.
Other Causes Still Matter
Infections, medications, foods and autoimmune activity are more established causes. See the full list of hives causes.
What You Can Do
- Treat hives with a non-sedating antihistamine as directed
- Build stress-lowering habits such as exercise, sleep and relaxation
- Keep a symptom and stress diary to spot patterns
- See a doctor if hives persist or recur

When to Call 911
Treat these symptoms as an emergency and call 911 if hives appear together with shortness of breath, a hoarse voice or trouble swallowing, swelling of the face, tongue or throat, a racing heartbeat, fainting, or vomiting and severe stomach cramps soon after a food, medication or insect sting. Do not wait to see whether they pass.
When to See a Doctor
See a doctor if your symptoms last more than a few days, keep coming back, cover large areas, or interfere with sleep or daily life. Patients with stress and hives can book an online or in-person consultation at Dr. Tiffany Young’s Hives Treatment Center in San Francisco.
