In summer, food is easy to ferment and breed bacteria after high temperature, and people are prone to intestinal infections and excessive gas production after eating. Especially for the elderly, gastrointestinal resistance is lower, more likely to have indigestion and intestinal flatulence and other symptoms. Now I would like to introduce a simple and effective abdominal breathing method to relieve flatulence, Shun Abdominal Breathing. The so-called smooth abdominal breathing is to inhale the small abdomen gradually bulging, exhaling the small abdomen gradually tighten. Specifically, it is first slowly inhale through the nose at the same time convex abdomen, inhale enough breath after holding the breath for 3 — 5 seconds; and then slowly exhale to tighten the abdomen, while lifting the anus. About 8 times a minute. If you have cardiovascular disease can not hold your breath, a minute about 15 – 20 times. Each time you can do 5 to 10 minutes continuously, twice a day, exercise cycle not less than 100 days. Can do inhale unintentionally, exhale slightly lift the perineum, help to achieve the natural tightness, do not hold your breath and not nervous, on the frail and sickly people easy to effect, can achieve the purpose of qi fitness. It greatly increases lung ventilation, strengthens the respiratory function, promotes lung circulation, increases the oxygen content in the blood, and also improves the function of the nervous system. At the same time, through the exercise of smooth abdominal breathing, the practitioner can strengthen the contraction force of the abdominal muscle groups. This improves the blood circulation in the thoracic and abdominal cavities, realizes the massage effect on the abdominal organs, enhances the peristalsis of the stomach and intestines, strengthens the digestion of food and nutrient absorption, and correspondingly strengthens the nutrient supply to other organs, and promotes the coordination of the systemic functions of various organs.
