Final answer:
Gesturing or walking around a bit during a speech can help siphon off excessive nervous energy.
Step-by-step explanation:
Gesturing or walking around a bit during your speech can help siphon off excessive nervous energy. It is true that these actions can help relieve some of the anxiety and tension that comes with public speaking. By using gestures and movement, you can channel your nervous energy into physical actions, which can help you feel more grounded and focused. However, it is important to strike a balance and use these techniques purposefully, as excessive movement and gestures can also distract the audience from the content of your speech.
