Stress

People with psoriasis often report flare-ups during stressful times. In fact, people with psoriasis are more likely to have a stress-related disorder.

How stress triggers psoriasis

Scientists don't know exactly why stress triggers psoriasis but believe it has to do with the immune system. Dr. John Koo, professor of clinical dermatology at the University of California, San Francisco, said inflammation is the body's way to cope with stress. Just as your immune system responds to injury and infection by sending out chemicals that cause inflammation, Koo suspects the immune system responds the same way to mental stress. In people with overactive immune systems, like in psoriasis, this can cause problems.
