Mineral Chemistry & Physiological Effects
1. Sulfur Springs (Iwo-sen): Clear micro-bacterial congestion and expand peripheral blood vessels, significantly easing hypertension.
2. Bicarbonate Springs: Naturally soften skin keratin and facilitate epidermal cell turnover.
3. Hydrostatic Pressure: Floating in warm water reduces skeletal gravity weight by 90%, allowing tight paraspinal muscles to fully relax.
