The medical principle of sand bath is that high-temperature sand is transmitted to the deep layer of human tissue through pressure, which accelerates blood flow and promotes blood circulation, thereby expanding peripheral blood vessels, adjusting the physiological response of the whole body, activating and restoring nerve function, improving the metabolism of the affected part, activating the function of reticuloendothelial system and adjusting the overall balance of the body, thus achieving the effect of health care.
From the perspective of modern rehabilitation medicine, sand bath also has a good magnetic therapy effect. It has good curative effect on rheumatic arthritis, rheumatoid arthritis, chronic lumbago and leg pain, and vascular thromboangiitis. Through the dual functions of sand bath hyperthermia and magnetic therapy, the blood circulation of human body can be effectively promoted, blood vessels can be dilated, and the physiological response of the whole body can be adjusted, so as to activate and restore the nervous function of human body, improve the metabolism of diseased parts, activate the function of reticuloendothelial system, and adjust the overall balance of the body, thus achieving the effect of treating diseases.
Sand bath has a wide range of applications, except for the elderly, the sick, infants, pregnant women, menstrual women and patients with organic diseases, such as migraine, sequelae of nervous system diseases, hypertension, Raynaud's disease, arthritis and low back pain.
There are detailed descriptions of sand bath therapy in China's ancient medical works, Qian Jin Fang Yao and Ben Cao Bu. As recorded by Chen Zangqi in Herbal Supplement, in June, the hot sand in the river was dominated by stubborn wind and cold, and the bones and muscles contracted, the wind paralyzed and the blood vessels were cut off. Dry sand is extremely hot, and it is easier to sit in it when it is cold. After sand bath, the whole body blood circulation is accelerated, which is beneficial to keep the meridians unobstructed and then attack evil, especially for the treatment of cold-dampness disease.
