1. Body language is an important aspect of communication that can both consciously and subconsciously send messages.
2. Body language signals may have different meanings in different contexts and cultures, so it is important to be aware of how your signals may be perceived.
3. Effective public speaking body language includes making eye contact with individuals in the audience, standing close enough to seem friendly but not too close, having open and relaxed body posture, and using gestures to reinforce your message without distracting movements.
