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 subconsciously. The technique of "reading" people is used frequently. For example, the idea of mirroring body language to put people at ease is commonly used in interviews. Mirroring the body language of someone else indicates that they are understood.
Physical expressions like waving, pointing, touching and slouching are all forms of nonverbal communication. The study of body movement and expression is known as kinesics Humans move their bodies when communicating because, as research has shown], it helps "ease the mental effort when communication is difficult." Physical expressions reveal many things about the person using them. For example, gestures can emphasize a point or relay a message, posture can reveal boredom or great interest, and touch can convey encouragement or caution.
Remember that body language varies greatly with people and especially with international cultures (so be very careful when applying Western understanding to Eastern non-verbal language). In this witty, sensual, poignant tale, New York Times bestselling author Suzanne Brockmann explores destiny, deception, and that steamy tipping point between deep friendship and romantic love. Some researchers put the level of nonverbal communication as high as 80 percent of all communication when it could be at around 50-65 percent. Different studies have found differing amounts, with some studies showing that facial communication is believed 4.3 times more often than verbal meaning, and another finding that verbal communication in a flat tone is 4 times more likely to be understood than a pure facial expression
