The Doctors and celebrity voice coach Roger Love invite you to take a deep breath... are you doing it properly? Roger explains many people gulp shallow breaths of air where they raise their chest and shoulders and speak as the shoulders fall back down. However, the better technique, diaphragmatic breathing, involves breathing in through the nose and then filling the belly with air. As you speak, the stomach comes back in.
This type of breathing is beneficial in that it aids in stress management and helps to keep you calm. It keeps your pulse at a normal rate, slows your heart rate so you can stay calm and relaxed, and it helps you sound better when speaking.
Psychiatrist Dr. Ish Major explains when we do the opposite, and take short shallow breaths, it's our reaction to negative feedback. We think, feel, do. If we think of something that doesn't seem cool, we feel nervous, and that triggers the body to take those shallow breaths preparing the body for fight or flight. He recommends the four-by-four rule. Take four breaths in as you count to four, let it out as you count to four again, and repeat this four times.
