What Is Clammy Skin?

Clammy skin refers to wet or sweaty skin. Sweating is the body’s normal response to overheating. The moisture of sweat has a cooling effect on your skin.

Changes in your body such as physical exertion or extreme heat trigger your sweat glands, causing your skin to become clammy. This is normal. However, clammy skin that occurs for no apparent reason can be the sign of a serious medical condition.
