If you experience these sensations, you might want to consider a short bout of mindfulness meditation. Sit down in a comfortable position, close your eyes, and take 10 deep breaths, in and out through your nose. Focus on only the sensation of your breath. Physical pain, tightness, and negative thoughts may arise. If they do, do not ignore them. Rather, acknowledge them non-judgmentally, let them go, and then return to focusing on your breath.
