As Chinese acupuncture and Tui Na have become popular among foreigners, Chinese qigong exercises have also caught up with the latter, a fact I witnessed at the Quetzling Chinese Hospital in Germany. Why are qigong exercises out of the country and popular with foreigners? Qigong is a physical and mental exercise skill that integrates the body, breath and mind, emphasizing the “three tunes in one”. It is easy to learn, and long-term practice can adjust yin and yang, harmonize qi and blood, unblock meridians and channels, cultivate true qi, and make people’s life flourish, so that the weak can be strong, the sick can be healthy, and the old can be strong again. Hua Tuo said, “If you shake, you will be able to eliminate the grain qi, the blood will flow, and all diseases will not be born. The effects of qigong are not only confirmed by many practitioners, but also confirmed by modern medical scientific experiments. 1. The effect on the nervous system The practice of qigong can make the nerve function repaired and adjusted. The amplitude of alpha wave in the EEG increases when practicing gong, and it is concentrated in the frontal part (this is the main difference with the quiet occipital part with eyes closed in alpha wave), and it makes the left and right brains tend to be synchronized, which indicates that the orderly brain function is enhanced. At the same time, it can also make the plant nerves adjusted; make the sensory function, motor function and thinking function strengthened. 2, the effect on the blood circulation system The practice of gong can make the heart, large circulation and microcirculation improved, and also can make the plasma estradiol fall, suggesting an anti-aging effect. 3.Role on respiratory system Oxygen consumption and CO2 emission are reduced when practicing gong, which can reduce the number of breaths and significantly enhance lung function. 4, the effect on the digestive system Practice can increase the secretion of saliva and digestive juices in the intestines and stomach, which can enhance intestinal peristalsis and strengthen the digestive function. 5, the role of the endocrine system The practice of gong can make the pituitary gland and the whole body endocrine tissues and organs get reasonable regulation. For example, the level of adrenaline and norepinephrine metabolism decreases, growth hormone decreases, and cholesterol concentration in blood decreases. Clinically, the practice of qigong has cured many patients with diabetes, hyperthyroidism, amenorrhea and other endocrine-related diseases. Yi Jin Jing, Five Animal Play, Six Characters, Eight Duan Jin, Big Dance, Twelve Methods of Guiding and Health Care, Mawangdui Guiding Technique, Taiji Health Staff, etc. are all good fitness qigong exercises.
