What is flushing

Flushing is a temporary redness of the face and neck. It may also be accompanied with a warm feeling.

What causes flushing

Flushing is caused by a dilation, or opening, of the blood vessels in the face. This brings more blood to the surface of the skin. The body uses this mechanism to “let off” heat, because the blood is warm and the extra heat is released into the cooler, outside environment. Alcohol and drugs, including some chemotherapy drugs, cause flushing.
