Some skin conditions, like dryness and itching, can be controlled. Also, if you keep your body healthy with good nutrition and enough exercise and rest, you will look and feel younger. You are never too old to take care of your skin. Dry skin, which causes itching, is very common as you get older. Your skin may be sensitive to certain cosmetics or fabrics which can be irritating.
Medications sometimes cause itchiness.
Whatever the cause of dry skin, there are things you can do about it. For example, some people don't really need a full bath or shower every day, so they might try taking a sponge bath, especially in the winter. Use a mild, nonperfumed soap and apply a simple moisturizing lotion to itchy areas after bathing. Moisturizing the skin may be needed as often as twice daily. Wear cotton next to your skin if wool is irritating.
