The use of physical behaviour, expressions, and mannerisms to communicate nonverbally, often done instinctively rather than consciously is called body language. There are five common types of body language. They are raised eyebrows, mirroring, head tilt, crossed arms, and fidgeting with objects.
A lot about the person can be said from body language. It has also been said that body language is more important than tone of voice and choice of words when communicating true feelings. The ability to understand and interpret other people’s body language can help one to pick up on unspoken issues or feelings.
