What is a common sign of shock?

A common sign of shock is pale or clammy skin. This occurs due to the body’s response to decreased blood flow and oxygen delivery to the tissues, leading to a constriction of peripheral blood vessels. As the body tries to prioritize blood supply to vital organs, such as the heart and brain, the skin can become cool and pale because blood is shunted away from less critical areas. Clamminess can develop as the body continues to sweat in response to stress, further contributing to this appearance. Recognizing pale or clammy skin is crucial, as it can indicate a serious underlying condition that requires immediate medical attention.
