1. Skin care and fitness functions of hot springs Hot springs are also called boiling springs, mineral springs and Yuquan, which were called "Shenshui" and "Shenxian Water" in ancient times. It is a kind of groundwater from deep in the earth's crust and has a certain ground temperature. Hot spring water contains sulfur, minerals, carbonic acid gas, hydrogen sulfide, phosphorus, calcium, magnesium, iron, potassium, sodium, strontium, chlorine, fluorine and other elements, as well as gases such as radon, nitrogen, free carbon dioxide and radioactive elements.
The skin cleaning and fitness function of hot springs is mainly due to the comprehensive effects of chemical composition, warmth and special pressure and buoyancy of mineral water on human skin and internal organs, especially on nervous, endocrine, immune and metabolic systems.
When soaking in a hot spring, the minerals in the hot spring dissolve into ionic state and enter the body from the skin. Potassium ion can stimulate nerve endings, affect vasodilation, and promote the synthesis of protein, fat and sugar in the body. Magnesium ion participates in glucose metabolism in liver, reduces the excitability of nerves and muscles, and can reduce blood pressure and cholesterol content in blood. Hydrogen sulfide has the functions of relieving itching, softening epidermis and detoxifying. Radon gas entering the body can reduce the excitability of nerves, and has the functions of sedation, analgesia, anti-inflammation, improving blood circulation and promoting metabolism.
For healthy people, hot spring bath can improve skin resistance, regulate nerve function, accelerate blood circulation, promote metabolism, and make skin rosy, white, soft and attractive.
