Deep Breathing
Mental stress would activate the sympathetic nervous system and cause your body to feel more alerted or aroused. During this response, stress hormones would be produced and trigger some issues such as constricted blood vessels, quick breathing, or fast heartbeat. Some deep breathing techniques would help control these issues by activating the parasympathetic nervous system. Several common exercises include abdominal breathing, paced respiration, belly breathing, and diaphragmatic breathing. The main purpose is to make you focus more on the breath and make it deeper and slower. When you breathe in deeply, the lungs would expand fully to slow the heart rate, which would relax your mind.
