Body language is a form of non-verbal communication, which consists of body posture, gestures, facial expressions, and eye movements. Humans send and interpret such signals almost entirely subconsciously.
Body language is the unspoken or non-verbal mode of communication that we use in every single aspect of our interaction with another person. It is like a mirror that tells us what the other person thinks and feels in response to our words or actions. 55% of the messages that we convey to other people are transmitted through body language. The actual verbal communication accounts for the other 38% in tone of voice and only 7% in the words we use (*When verbal context is ambiguous).
Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, relaxed state, pleasure, amusement, and intoxication, among many other cues.
