There is no sure way to prevent psoriatic arthritis (PA). However, people can take several steps that may lessen the likelihood of experiencing progression or flare-ups associated with arthritis and psoriasis. Such steps include:

• Eat a healthy diet. To date, no specific food or nutrient has been proven to prevent or control arthritis. However, it is known that antioxidants, such as vitamins C, E and A, prevent cell damage that may contribute to arthritis. Diets high in olive oil and vegetables have been linked to reduced risk of rheumatoid arthritis, and the mineral selenium has been linked to reduced risk of osteoarthritis. Scientists have not conclusively linked any foods to arthritis flare-ups. Nonetheless, patients should exclude foods from their diets that appear to make symptoms worse.
  
  
• Maintain a healthy weight. A healthy weight places less strain on joints, leading to reduced pain and increased energy and mobility.
  
  
• Exercise regularly. In some patients, exercise alone can help relieve many of the symptoms of arthritic conditions such as pain and fatigue.
  
  
• Use cold and hot packs. Cold has a numbing effect and can dull the sensation of pain, whereas heat can relax tense muscles and relieve pain.
  
  
• Experiment with relaxation techniques. Stress can worsen symptoms associated with PA. Patients should try to reduce stress and increase relaxation through various techniques, such as meditation or prayer, yoga, tai chi, deep breathing, biofeedback, self-hypnosis, visualization or guided imagery.
  
  
• Use proper body mechanics. Individuals should observe good posture and ergonomics and avoid straining areas vulnerable to arthritis, such as finger joints.
  
  
• Care for skin. Daily bathing can help remove psoriasis scales. Use of hot water and harsh soaps should be avoided, and patients should pat themselves dry after a shower or bath and apply a moisturizing cream (without alcohol) while skin is still damp. Humidifiers can help keep inside air moist.
  
  
• Expose skin to moderate sunlight. Sunlight slows down cell growth, helping improve psoriasis. However, patients should remember that too much sunlight can damage the skin and cause skin cancer.
