When you have psoriasis, the most important thing is to follow your doctor’s advice. Still, you can do a lot on your own to help control and prevent flare-ups.

Symptoms get worse when your skin is dry, so keep it moist with creams and ointments. Thick and oily ones, like petroleum jelly, are usually best. They're better at trapping moisture beneath the skin. To help remove scales, apply cream on top of them, then cover the area with plastic wrap or another waterproof material. Leave it on for a few hours, then remove it. Learn more about lotions and other topical treatments for psoriasis.

Be careful with your skin. Never pick at patches or scales, as you may make your psoriasis worse. Use caution when trimming your nails. If you cut yourself, it might make symptoms flare. Limit your baths and showers to 10 minutes at a time. Avoid very hot water.

Climate can have a big effect on psoriasis. For many people, cold, dry weather makes symptoms worse. Hot weather usually makes them better, but not always. Read more on how to manage psoriasis during fall and winter.

It's important to keep your skin moist. Turn on the humidifier when the air inside your house is dry. Learn about the different types of humidifiers and how to use them.

Let your doctor know about all the medications you take, even over-the-counter ones. Ask if they could affect your psoriasis. Drugs that are known to make things worse include:

  • Lithium, used to treat psychiatric disorders
  • Propranolol and possibly other beta-blockers, which are prescribed for heart conditions
  • Quinidine, medication for an irregular heartbeat

If you're using any of these medications, ask your doctor about substitutes. Know about these and other drugs that can trigger psoriasis flares.

It's extra important for people with psoriasis to avoid bumps and cuts. Trauma to your skin can cause a flare, a condition called Koebner's phenomenon. Infections can also cause problems. Be especially careful when shaving. Avoid acupuncture and tattoos, and do your best to prevent insect bites and chafing. Get more information on Koebner's phenomenon and psoriasis.

The ultraviolet rays in sunlight slow the growth of skin cells, so getting moderate doses of sun is good. But make it brief – about 20 minutes or so at a time. And use sunscreen. Sunburn can trigger psoriasis, and it raises your risk of skin cancer. Some medications can make your skin more sensitive to ultraviolet rays, so talk to your doctor first.

Although it hasn't been proven, many people link flare-ups to stress. So, try to relieve your anxiety. That may be easier said than done, but you can try relaxation techniques like meditation or yoga, for starters. Find out how to manage the emotional impact of psoriasis.

The connection between alcohol and psoriasis isn't clear, but some think it can worsen symptoms, especially in men. Alcohol can be dangerous if you're using certain psoriasis drugs, so check with your doctor.

Although no studies have shown a link between diet and psoriasis, experts recommend that people with the condition eat a well-balanced diet that's high in fruits and vegetables. Some people say their symptoms improve when they remove dairy or gluten. Exercise may also help. Some studies show excess weight can trigger flares, so stay at a healthy weight.
