Strengthening lung respiratory function can improve systemic oxygen supply and immunity. "Sit-in Breathing" is a good exercise for lung health care.

The specific steps of meditation breathing are as follows: 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 5 or 6 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.

"Sit-in Breathing Method" is extracted from the ancient China's work of expelling the old and absorbing the new, and guiding health. Through posture adjustment, breathing exercise, physical and mental relaxation, concentration and rich imagination, medical and health care effects have been achieved. This is because the lungs are exercised in the process of deep breathing. Chinese medicine has long told us that "qi belongs to the lung, and lung is the source of qi". At the same time, sitting breathing can improve heart function and is also a good massage for gastrointestinal tract.
