It’s one of the most common triggers, says dermatologist Colby Evans, MD, chairman of the board of directors of the National Psoriasis Foundation.
Stress puts your body in a protective mode. It sends out the chemicals that cause inflammation and lead to flares.
What you can do: Try exercise, yoga, or massage, Evans suggests, or take up hobbies you enjoy. They can ease your stress. So can techniques like progressive muscle relaxation, focused breathing, and mindfulness meditation.
You can talk to a therapist or stress-management counselor to get more ideas.
"When the weather is colder and drier, psoriasis tends to flare," Evans says.
Most people find their skin is better in the summer and worse in the winter. That's probably due to the lack of sun in the winter, says Mark Lebwohl, MD, chairman of dermatology at Mount Sinai Hospital.
What you can do: Use a moisturizer, Lebwohl suggests. A cool-mist humidifier in your bedroom can also help.
Many psoriasis treatment centers have phototherapy units, too. Or you can get one for your home. They mimic sunlight and may help ease your symptoms. Talk to your doctor to see if it's the right treatment for you.
What you can do. "It is important to let any doctor who is prescribing you medication know that you have psoriasis," Evans says.
Sometimes your doctor may be able to prescribe another drug that doesn't lead to flare-ups. Or she may be able to lower the dose of your medicine.
Cuts and Bruises
If your skin is cut or injured, you could get a flare in that area. Your doctor may call this the "Koebner phenomenon."
What you can do. Cut back on activities that could create friction or lead to you getting hurt, Lebwohl says.
If you have a skin injury and notice a flare-up starting in that area, treat it right away.
