& lt sitting posture: leaning forward > sitting forward can not only calm the whole nervous system, but also calm the brain. Especially for beginners of yoga, leaning forward in a sitting position is easier than leaning forward in a standing position, because it takes a little more effort and a certain balance ability to complete leaning forward in a standing position. Generally speaking, as long as you practice reclining posture, you will lay a good foundation for practicing standing posture, and also provide a practical choice for patients with hypertension or other diseases. If they were smart and obedient, they wouldn't put their heads under their hearts. Leaning forward can affect many energy centers (chakras) and important organs in the body at the same time, but the most beneficial point is Liyuan (also known as the central chakra or the second chakra). This chakra is responsible for the kidneys and adrenal glands. Therefore, practicing forward posture is an effective way to balance and strengthen the functions of these organs. The forward leaning type is mainly divided into rhombic type, baddha konasana type, straddle type, one-leg exchange stretching type, archery type, back stretching type, cow face type and boat shape. & lt sitting posture: lean back > lean back generally requires strong body, and lean forward requires flexibility. At the same time, leaning back is a good way to strengthen the body and regulate the body, especially for the muscles of the back, legs and buttocks. If you feel that you don't have the strength to do the backward posture, please practice the one-star stance first, such as the warrior posture. 1, backward posture can enhance the flexibility of the spine, help improve the standing posture and sitting posture, and maintain the elasticity of the spine. They can also benefit the nervous system by increasing the blood supply to the spinal region and the nerves extending from the spinal column. 2, stretch the abdominal area, and can help digestion to a great extent, because they can regulate the generally weak abdominal muscles and digestive organs. They can also expand and open the chest area and increase the flexibility of the shoulders, thus helping the chest to expand more. This can create better conditions for deep breathing and benefit the respiratory system. When the body is still a grandfather, the brain will also enter a passive state of calm. 3. Reclining will affect many energy centers. For example, the throat chakra, which is located in the energy center of the throat, is affected whenever the neck is straightened or put down. When performing a full backward tilt, all air wheels will be affected. However, the most affected and benefited chakra is the umbilical chakra, the third energy center, which is closely related to the abdominal plexus. This chakra is also related to the pancreas. The pancreas has chemical effects on the stomach, liver and spleen. From the point of view of energy, all organs are interrelated and support each other. The pancreas regulates the sugar content in the body by producing insulin. If the content of insulin is reduced, it will easily lead to diabetes, and muscles can no longer effectively use glucose. The function of the spleen is to distinguish between pure and impure food that everyone eats. These physical functions and their related chakras also affect our mood. For example, our ability to distinguish the value of things is very important. When the energy of the spleen is blocked, it will lead to negative emotions, which will distract us, worry too much and feel "stagnant". In this way, the spleen affects our ability to make decisions and move on in life.

It has the function of sorting out and calming the body and mind; So it not only makes the body radiant, but also makes the delicate chakra system full of vitality. The autonomic nervous system is controlled by the brain stem and hypothalamus, which is responsible for all the body functions we don't know. These functions include digestion, respiration, gland and hormone secretion, heartbeat, blood circulation and kidney and liver functions. Vagus nerve is an important part of the parasympathetic nervous system in our body, and it also affects the sympathetic nervous system. Parasympathetic nervous system is a quiet and relaxed part of autonomic nervous system, which can balance the activity and stimulation of sympathetic nervous system. Vagus nerve extends from the brain to the spine and ends in the abdominal plexus. This nerve is related to seven energy centers (chakras), which are closely related to various sympathetic plexus in the body. By making the nerve center full of vitality, energy and strength gather together, thus releasing the energy trapped in the body. This can make better use of energy. We can release energy by performing spinal torsion, and at the same time make all the subtle parts of the body and physical strength (related to the gas wheel) full of vitality.
