Is this "body language" refer to a "gesture?"

Native speaker’s answer

Body language refers to how you position your body in a setting, as that can often communicate things about one's mood, personality, or relationship with others. For example, crossing your arms in front of your chest is a type of body language that could signal self-protection or creating distance with others. This is the idea being shared by the speaker in this video. Ex: Her body language is very relaxed and open, so others find it easy to talk to her. Ex: She is always slumping or on her own, and her body language shows that you shouldn't get close to her.
