Chapped hands are a result of very dry skin. Dry skin occurs when the moisture, or water, content of the skin is decreased for any reason.

What is going on in the body?

The surface of the skin holds a certain amount of water. When the water content decreases, the skin becomes dry, itchy, and uncomfortable. Some people have very sensitive skin that is easily irritated. Since a person's hands are often exposed to elements such as cold and moisture, hands may become irritated before other parts of the body do.

Some individuals have a genetic predisposition to dry skin. As people age, their skin tends to become drier. Dry air, resulting from winter's low humidity and the use of indoor heat, can cause skin to dry out. Long, hot baths and showers can also make skin dry.
