High-Concentration Carbonated Spring
A highly recommended high-concentration carbonated spring said to promote blood circulation far more than ordinary bathwater. Because the temperature is set on the lukewarm side, you can enjoy a long soak without putting strain on the body. Fine carbon dioxide bubbles cling to the skin, gently warming you from the core. It is also expected to help relieve poor circulation, daily fatigue, and lower back pain, leading both body and mind into a deep state of relaxation.
