Barefoot exercise can exercise the flexibility of ankle joint. Let children often walk barefoot, so that their tender soles are directly rubbed by the soil, which can not only enhance the strength of plantar muscles and ligaments, but also improve the flexibility of ankle joints, which is conducive to preventing flat feet. Massage on foot acupoints when barefoot can also regulate the functions and functions of various organs, including the brain, promote blood circulation and metabolism, thus accelerating brain development and enhancing children's thinking sensitivity and memory. Some people say that walking barefoot on cobblestone roads is not suitable for children, which is completely wrong. Walking barefoot on pebbles is suitable for people of all ages. Even toddlers who dare to challenge the sharpness of cobblestone roads barefoot can participate, and I believe you can enjoy it. Exercise the soles of children's feet barefoot, starting with toddlers. Parents should encourage their children to walk barefoot, let them experience the feeling of stepping barefoot on a flat floor first, and of course, avoid barefoot touching the ground and catching cold. When the child is two or three years old and has enough resistance, you can take him to the outdoor lawn or concrete floor to experience barefoot and stimulate the child's interest in barefoot exercise. After the child is further adapted, he can be allowed to walk barefoot on more uneven roads or roads with different temperatures (such as cobblestone roads). This step by step can not only promote the healthy growth of children, but also enable children to have a pair of healthy, thick and tough soles.
