Stress

Scientists believe that heavy drinking can trigger psoriasis flares. More research, however, is needed to know what the links are. Doctors say avoid alcohol altogether to help prevent reactions.

Another reason to put down your drink? Some psoriasis medications and alcohol don’t mix.

Instead, try a nonalcoholic thirst-quencher like iced tea. Or walk around the block to unwind. Daily exercise and up to 20 minutes of sunlight can soothe psoriasis.
