Closed body language refers to nonverbal cues that indicate a person is feeling defensive, uncomfortable, or unapproachable. Common signs include crossed arms, hunched shoulders, and avoiding eye contact. These gestures can create a barrier in communication, making it difficult for others to engage with the individual. This type of body language can occur in various situations, such as during conversations, meetings, or social gatherings. Understanding closed body language is essential for improving interpersonal interactions, as it can signal the need for a more open and inviting approach to foster better connections.
