Put your hands flat on your knees, sit up straight and close your eyes gently. Inhale slowly from the nasal cavity first, so that the lower part of the lungs is filled with air, while the lower abdomen bulges slightly, consciously assuming that the inhaled airflow has reached and accumulated in the lower abdomen (that is, air sensation). In the process of inhalation, due to the upward movement of the chest, the diaphragm moves downward and the chest inflates, so that the breath reaches the upper part of the lung and expands to the uppermost edge. This process takes about five or six seconds.
Then keep breathing for 5 seconds (more than 10 seconds can be achieved through practice), so that the lungs have time to absorb all oxygen.
Then exhale slowly, and the ribs and chest gradually return to their original positions. Before starting the next inhalation, pause for two or three seconds before inhaling. Repeat this action 10 times. As long as you keep practicing every day, gradually form a habit and persevere, you can strengthen the pulmonary respiratory function.
The meditation breathing method is extracted from the ancient movement of expelling the old and absorbing the new, guiding and waiting for health preservation in China. Through posture adjustment and breathing exercise, it relaxes body and mind, concentrates attention and imagination, and receives medical and health care effects. This is because the lungs are exercised in the process of deep breathing. At the same time, sitting breathing can improve heart function and is also a good massage for gastrointestinal tract.
