You may not think that something as simple as Epsom salt can improve psoriatic arthritis symptoms, but it can. A psoriatic arthritis Epsom salt soak is great for joint inflammation and discomfort.

How Epsom salt works. Epsom salt has high magnesium content. Magnesium helps to loosen up your muscles, relieving tension and tightness. If you feel joint stiffness that you can’t work through, try soaking in an Epsom salt bath before stretching or exercising. You may have a better range of motion for your exercises.

There is no scientific research to back the effectiveness of Epsom salts for treating psoriatic arthritis. Still, many medical doctors recommend an Epsom salt soak to patients who suffer from joint stiffness and pain. People who utilize Epsom salt soaks also say that the practice works.

How to use an Epsom salt soak. Measure at least one and one-fourth cups of Epsom salt and pour it into your bathtub with hot water. The salt dissolves, and you can then soak in the bathwater. Plan to soak for at least 15 minutes for the best results. You can soak longer, but experts say that 15 minutes is enough.
