Nonverbal communication includes things like tone of voice, body movements, facial expressions, physical touch, as well as details of your appearance such as what you’re wearing. Nonverbal communication may also include space and time, such as how far you stand from the other person, whether you approach them quickly or slowly, how fast you speak, etc.
Nonverbal communication is important because when it matches with your verbal words, it increases clarity, rapport, and trust between you and the person you’re socializing with. However, if your nonverbal and verbal communications do not match, it can result in tension, confusion, and mistrust between you and the other individual.
Don’t cross your arms or legs because it can make you appear closed off and antisocial. Make eye contact to show you’re listening and engaged, but don’t stare. Staring without blinking can cause the other person to feel threatened and uncomfortable. Nod every once in a while to portray that you’re following what the person is saying. Smile and laugh when appropriate. Lastly, respect personal space and the amount of physical touch the other person seems comfortable with.
