Maintain constant healthy eye contact with your conversation partner.

While speaking, keep your hands above your waist.
Never put your hands on your face.

Keep your body calm by taking deep breaths and avoiding any fidgety movements.
Refrain from massaging your arm when it tingles or rubbing your nose when it itches.

While giving a speech outdoors, keep your eyes on your listeners and watch how they’re responding.
Avoid blinking your eyes frequently. Shield your eyes from the sun if you need to.
