All of your nonverbal behaviorsโthe gestures you make, your posture, your tone of voice, how much eye contact you makeโsend strong messages. They can put people at ease, build trust, and draw others towards you, or they can offend, confuse, and undermine what you're trying to convey.Your facial expressions, gestures, posture, and tone of voice are powerful communication tools. Hereโs how to read and use body language to build better relationships at home and work.While the key to success in both personal and professional relationships lies in your ability to communicate well, itโs not the words that you use but your nonverbal cues or โbody languageโ that speak the loudest. Body language is the use of physical behavior, expressions, and mannerisms to communicate nonverbally, often done instinctively rather than consciously.Whether youโre aware of it or not, when you interact with others, youโre continuously giving and receiving wordless signals. These messages donโt stop when you stop speaking either. Even when youโre silent, youโre still communicating nonverbally.
