Onsen bathing temporarily raises core body temperature; the subsequent drop promotes melatonin secretion, improving sleep quality. Buoyancy and hydrostatic pressure release muscular tension. Simple springs (high pH, gentle on skin) are the mildest choice for sensitive individuals. Chloride springs provide prolonged warmth via the salt film; sulfate springs are studied for direct neurological effects.
