How Your Environment May Cause Psoriasis Flare-Ups—and What to Do About It

Many people with psoriasis find that their flare-ups are triggered by a particular environmental factor. Most common factors are related to lifestyle—obesity, smoking, alcohol or stress, for example—or health exposures—HIV, physical trauma, some medications, or even strep infection, says board-certified dermatologist Nicole Seminara, M.D., from NYU Langone Health in New York City.

The National Psoriasis Foundation also includes allergies, diet, and the weather in its list of common environmental triggers, but Seminara says there’s not “much evidence” that those definitely cause flare-ups.
