Diaphragmatic Breathing

The diaphragm is the dome-shaped muscle below your lungs that helps you breathe. In diaphragmatic breathing, you learn how to breathe from the region around your diaphragm, rather than from your chest. This technique helps to strengthen your diaphragm, slow your breathing, and decrease your body’s oxygen needs.

To practice diaphragmatic breathing, lie on your back with your knees bent and a pillow under your knees, or sit up straight in a chair. Place one hand flat on your upper chest and the other hand on your stomach. Breathe in slowly through your nose. The hand on your stomach should move, while the one on your chest remains still. Breathe out slowly through pursed lips. Keep practicing this technique until you’re able to breathe in and out without your chest moving.

Pursed Lip Breathing

Pursed lip breathing is a technique used to relieve shortness of breath. To practice it, you first breathe in slowly through your nose with your mouth closed. Then, you purse your lips as if you were about to whistle. Finally, you breathe out through your pursed lips to a count of four.
