Body language is something we are aware of at a subliminal level. It is possible to make yourself aware of how your body language impacts on others. When you are aware, you can change things to convey an open minded attitude and empathy when it is needed and people will be more comfortable around you.
Communication is so much more than words. Sometimes the verbal communication contradicts the body language because body language doesn't lie. Facial expressions, hand movements, and direct eye contact also constitutes a large percentage of the actual comunication process. Have you ever seen someone not talk with their hands or use facial expressions? That is why during a phone conversation, much of the message is missing. An email relies strictly on the placement of words, which is a reason why so many emails can generate a wrong message.
Body language is the way we express feelings and thoughts naturally.
People studied it and interpret ate it. We can learn to read it and recreate it to communicate better.
I think that positive body language helps me communicate because it lets the person know that i care what they are talking about and I’m listening.
