Research the different types of body language the people use​

While the key to success in both personal and professional relationships lies in your ability to communicate well, it’s not the words that you use but your nonverbal cues or “body language” 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 you’re aware of it or not, when you interact with others, you’re continuously giving and receiving wordless signals. All of your nonverbal behaviors—the gestures you make, your posture, your tone of voice, how much eye contact you make—send 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. These messages don’t stop when you stop speaking either. Even when you’re silent, you’re still communicating nonverbally.In some instances, what comes out of your mouth and what you communicate through your body language may be two totally different things. If you say one thing, but your body language says something else, your listener will likely feel that you’re being dishonest. If you say “yes” while shaking your head no, for example. When faced with such mixed signals, the listener has to choose whether to believe your verbal or nonverbal message. Since body language is a natural, unconscious language that broadcasts your true feelings and intentions, they’ll likely choose the nonverbal message.Types of body language:Facial expressions Body movement and posture Gestures Eye contact Touch Space VoiceHope it helps you ;)
