Arthritis can be a difficult thing to handle. You can help yourself not get this debilitating condition, if you begin earlier in life to take preventive measures to lessen the effect it has on your health, by eating right and by moving certain joints certain ways. You sometimes can't completely prevent it, but you can lessen the effect.
Learn tai-chi. Tai-chi is a mind and body connective technique, that is also a form of light martial arts. Using tai-chi can help to convince yourself your body is not in as much pain as your mind believes. Some arthritis sufferers even claim that the use of this method allows them to use their mind to convince their body they are more flexible.
Get in the water. Water aerobics is a great low impact exercise for arthritis sufferers, because not only does it put minimal strain on joints, it also provides resistance for strengthening. If you are uncomfortable with doing these in large groups, learn a few moves and take to the pool. You will quickly become more comfortable.
Do not discount the need to get enough sleep when dealing with psoriatic arthritis. You need sleep now even more than before. If you are having trouble sleeping, talk with your doctor about medications that can help. Keep your bedroom a place for resting so that your body knows that heading to bed means time for sleep.
