Crossed arms often indicate defensiveness in body language. When a person folds their arms across their chest, it can signal that they are feeling threatened, uncomfortable, or resistant to what is being discussed. This posture may create a barrier between the individual and others, suggesting a desire to protect oneself from perceived emotional or physical harm. In social interactions, crossed arms can also hinder effective communication. Observers may interpret this gesture as a lack of openness or willingness to engage. Understanding this body language cue can help individuals navigate conversations more effectively and foster a more positive atmosphere in discussions.
