BATHING TIPS
AI Generated

Given the source's exceptionally high temperature of 82.8°C, the facility carefully adjusts it to a comfortable warmth. Before entering, perform thorough pre-bath rinsing to prevent sudden blood pressure fluctuations, then immerse yourself slowly and deliberately. After bathing, apply moisturizing care to prevent skin desiccation and lock in the thermal benefits.

EFFECT STORY
AI Generated

At neutral pH 6.4, this mineral-rich water envelops skin in a protective saline veil, preventing heat loss and cooling. The sulfur content proves particularly beneficial for those with peripheral circulatory disorders and chronic chilliness. Penetrating warmth from core to surface gently alleviates fatigue and stress-induced complaints, revitalizing body and spirit alike.

CAUTIONS
AI Generated

Those with sensitive skin or mucous membranes, and elderly guests prone to dry skin conditions, should refrain from bathing. When drinking, those under 15 should avoid ingestion; adhere to the daily limit of approximately 280mL.
