Body language is a type of nonverbal communication. It mainly includes facial expressions, body posture, gestures, eye movement, touch, and the use of space. Body language and tone of voice could be more powerful assessment tools than words. It has the potential to reveal a fake smile or a lie. Children begin to learn a great deal by seeing and hearing these powerful skills. Even when standing still, a person's body is telling a story.

This language is officially known as kinesics. Our brain's visual cortex has areas dedicated to different body postures and expressions. The limbic brain is most responsible for value judgements, and it plays a vital role. Albert Mehrabian, a body language researcher, developed the '55/38/7' formula to break down components of face-to-face conversations. He found that communication is 55% nonverbal, 38% vocal, and 7% verbal. People born blind can express the same body language as sighted individuals.

Humans and animals convey information through conscious and subconscious body movements and facial expressions. Like many animals, humans puff out their chests when establishing territorial dominance. Some of the most common body language are raised eyebrows, head tilts, and crossed arms. The higher the surprise, the more the eyebrows are raised, signalling emphasis.

People are typically perceived as more attractive when they tilt their heads. Crossed arms' interpreting 'defensive' attitude' is perhaps the most common body language gesture we encounter daily.
