Chewing gum to calm your nerves
Now, this tip might be inappropriate in certain situations. For example, you shouldn’t chew gum during an interview, even if it makes you feel less anxious. However, if you’re talking in front of a crowd at a distance, and they can’t see every detail of your jaw, chewing gum will help you calm your nerves.
However, this doesn’t mean you should come unprepared. A calm person who knows nothing about a subject is just as bad as an educated speaker whose nerves get the best of him or her. Chewing gum before or during stressful situations can help keep yourself calm and collected.
