How can you control your nerves?

Inhale. One of the few physical techniques you can use to combat nerves is: breathing exercises. Every time you breathe out, you are emitting carbon dioxide. As a result, the acidity in the blood decreases, more oxygen is supplied to your brain and you can think better and more clearly. It works like this: take a deep breath, hold your breath for a moment and then exhale slowly. It works against any kind of stress. Prepare yourself. Try to be ready for everything as much as possible. Rehearse your speech out loud. Try to create the conditions in which you will speak as best you can. Use notes. Calculate the duration of your presentation so that you can report it and stick to it. Arrive well in advance. Look ahead. Consider what can go wrong and what concerns or questions the audience may have. Make sure you have solutions and answers. Practice difficult statements. Make sure you have a sentence handy if you make mistakes: "I'll try again, this time not in Swahili." Never draw attention to a mistake or slip of the tongue. Don't apologize for nerves, mistakes, or anything else. Carry on, regardless.
