Foot is closely related to physical and mental health and is called the "second heart" of the body. There are many acupoints on the foot, and those acupoints are irritating, which is commonly called "foot reflex zone treatment", which refers to the treatment of various human organs and internal organs in the human body at the position corresponding to the foot. The necessity of two feet can be discussed from the "second heart". Heart is often the key, because the heart is the guarantee of vitality. However, because the feet are far away from the heart, coupled with the heavy volume, blood can easily flow from the heart to the feet, while the blood flowing from the feet is more difficult to flow back to the heart. When there is a large amount of blood in the venous vessels of the lower limbs, the pressure of the lower limbs increases, so it is necessary to use the function of the muscle tissue pump of the lower limbs, that is, the muscle strength of the lower limbs is improved and isometric contraction is made. Squeezing the capillaries of the lower limbs helps the heart pump blood, and drives the venous blood of the lower limbs to flow into the heart according to the venous valve to carry out the whole process of blood circulation.
Therefore, the foot is very harmful to the circulation of qi and blood, and it is called the second heart of the body. The primary function of the heart is to keep all the normal blood supply to the body, keep the blood running and discharge waste. It can be explained that the blood circulation system of the foot is excellent, which will endanger the blood circulation, waste removal, qi and blood circulation and component supply of the whole body. If the blood circulation system of the foot is not good, it will endanger the blood circulation of the whole body. If you keep reasonable fitness exercises every day, such as jogging and walking, you can promote the muscle tissue of lower limbs to carry out aggregated fitness exercises.
