An oatmeal bath can help to relieve itchy skin, especially when a person has a condition such as eczema, according to WebMD. The bath should be lukewarm, and the person should soak for 15 to 20 minutes.
A cold compress may also help to relieve itching, explains WebMD. Those who wear loose, comfortable clothing may also find the itching stops, as the cloth does not irritate the skin. Over-the-counter medications that contain hydrocortisone are also useful when skin is itchy. Keeping fingernails short may help some people, as it is more difficult to damage the skin and worsen the problem.
