3. Gesture: Moving your hands occasionally while you speak actually helps you think and speak more clearly. The location of your hands also affects other nonverbal behavior. When you are conversing with someone standing up, if you place your hands and arms at your sides your energy goes down, your voice lowers and can become more monotone, and you show fewer facial expressions. If you’re nervous, bring your hands to the level of your waist, and you will become calm and centered. If you gesture occasionally with your hands at the level of your upper chest or above, your voice automatically goes up, increases in volume, and has more variations; you actually become animated.
