The way you interpret stress influences your public speaking skills
People with a fear of public speaking tend to believe their nervousness is more apparent to others than is actually the case. They focus their attention on physiological reactions, such as blushing and perspiration. Research has shown however that individuals who report being anxious about public speaking actually show no difference in objectively measured physiological reactions when compared to individuals who report not being anxious about public speaking. When the same individuals were instructed to reframe their stress as a positive coping tool they paid less attention to the physiological reactions such as blushing, increased heart rate and perspiration.
