Box breathing, also known as four-square breathing, involves exhaling to a count of four, holding your breath for a count of four, inhaling at the same pace, and holding air in your lungs for a count of four before exhaling and repeating this breathing pattern. Box breathing is helpful for stress management and reducing blood pressure while minimizing hypertension. This relaxation technique is effective in reducing anxiety and is easy to learn and practice any where and at any time.
