青年期を対象とした温泉水素水飲用の安全性

The safety for drinking of hot spring hydrogen water was examined for 27 healthy women. The research method was the crossover comparison examination of hot spring hydrogen water and tap water for four weeks. The blood cell count, liver function, kidney function, plasma lipids, and electrolytes were measured before and after drinking. Mean corpuscular volume and mean corpuscular hemoglobin concentration significantly decreased after drinking of hot spring hydrogen water and tap water. The plasma total protein, blood urea nitrogen, and total cholesterol significantly decreased after drinking the hot spring hydrogen water. Other data showed no significant changes. These results suggested that the drinking of hot spring hydrogen water was almost safe.
