Safe bathing policy

"Blood sugar level? I don't have diabetes."
I know. Just note that even a healthy person could end up unconscious due to a sudden drop in blood sugar levels when you soak in bath on an empty stomach.
Also, note that hot spring isn't always utopia. It doesn't welcome you if you've drunk too much. Finally, please know that nutrients in the hot spring water is NATURAL. It might sometimes give you an allergic reaction or irritate your skin. Therefore, rinsing your body with tap water (warm or cold) before you get dressed might help.
We do NOT hold responsible for any consequence by bathing unprepared.
