Physical gestures are movements of the body that convey messages or emotions without the use of words. These can include actions like waving, nodding, or pointing, which help to enhance communication. Gestures can vary widely across different cultures, with some movements having specific meanings in one culture but not in another. In addition to enhancing verbal communication, physical gestures can also express feelings such as happiness, anger, or confusion. For example, a smile can indicate friendliness, while crossed arms may suggest defensiveness. Understanding these gestures can improve interpersonal interactions and foster better relationships.
