The importance of exercise and diet on psoriatic arthritis

If you have psoriatic arthritis, try to take a holistic view of your self-care. That means not only taking treatment as your doctor has prescribed, but also looking after yourself as a whole.

Watch your diet


It’s a good idea to try to eat a balanced diet and exercise to help your joints.1 Being overweight can overload the joints and bones that are used to supporting the body.2 Although there’s no clear evidence that diet can affect PsA, some people with psoriasis report having milder symptoms when they ate more healthily.1 Certain foods can make inflammation worse, so try to avoid alcohol, sugary, processed or fried things, diet drinks, red meat and dairy, where possible.1 Instead, try replacing them with fruits and vegetables, beans and whole grains, fatty fish, avocados, flaxseed and olive oil, and green, white and black teas.1 Spices like turmeric, ginger and cayenne can also help calm inflammation.1 Kicking a smoking habit may also help – smoking has been shown to increase the risk of psoriatic disease.5

Keep fit


Exercise can help you destress and maintain a healthy weight.4 And very importantly if you have PsA, exercise reduce pain, improve flexibility, and keep your muscles and bones strong.5 It’s important to find activities that work for you as they need to be something that will help your joints, stiffness and pain, rather than make it worse, so please check with your healthcare professional before starting anything.5 And most importantly – take note of any progress you make and congratulate yourself – every step is a step in the right direction!

5 tips for getting active4,6

  1. Start slow. Do little bits to begin and build up from there once you feel ready.
  2. Don’t overdo it. If you feel pain when you flex your joints after a workout, you may have pushed yourself too hard and need to take it easy for a bit.
  3. Enjoy yourself. Make sure you choose an activity you like or consider mixing a few up and doing different things on different days to keep it interesting.
  4. Stay hydrated. Not drinking enough liquid isn’t good at any time, but especially when you’re exercising.
  5. Consider yoga. The gentle movements can help keep joints moving and the breathing could help you stay calm.

Don't forget your skin and nails


Skin and nail psoriasis is common in people with PsA, so if you’re affected, make sure you pay special attention to yours.5 These days, we all try to wash our hands regularly, so make sure you moisturise well.6 Keeping your nails trimmed and using gloves to help you avoid irritants when doing chores or gardening is also a good idea.6 And if you’re out and about, make sure you protect your skin from the sun.7 Finally, while it may be tempting to have a good scratch when you wash your hair, please make sure you don’t.8
