Body language is a broad term for forms of communication using body movements or gestures instead of, or in addition to, sounds, verbal language, or other forms of communication. It forms part of the category of paralanguage, which describes all forms of human communication that are not verbal language. This includes the most subtle of movements that many people are not aware of, including winking and slight movement of the eyebrows. In addition body language can also incorporate the use of facial expressions.

Paralanguage, including body language, has been extensively studied in social psychology. In common parlance and popular psychology, the term is most often applied to body language that is considered involuntary, even though the distinction between voluntary and involuntary body language is often controversial. For example, a smile may be produced either consciously or unconsciously.
