温泉浴と血液循環時間に関する研究

抄録

The authors have studied the effect of the single bathing in the hot spring on the time required for the blood circulation and its relation to the character of the spring and the age, the disease and the blood pressure of the patient, and obtained the following results:
1) The circulation time in healthy persons is shortened immediately after the bathing both in the simple carbonate spring (37°C) and in “Unagi-yu” (alkaline sulphur spring, 44°C), but it is prolonged one hour after the bathing, being gradual in the simple carbonate spring bathing (37°C) and rapid in the alkaline spring bathing (44°C).
2) As almost similar phenomena are seen in the case of fresh water bathing (37°C and 44°C), they seem to be due to the thermal action of the bathing water.
3) Generally speaking, the bathing in the hot spring tends to lower both the maximal and the minimal blood pressures, and the fall keeps on going even one hour after the bathing. It is a characteristic feature of the hot spring bathing that the duration of the fall of the blood pressure is longer in the hot spring bathing than in the fresh water bathing.
4) The fall in the blood pressure induced by the bathing in “Unagi-yu” (alkaline sulphur spring) is somewhat irregular and rapid, but that induced by the bathing in the simple carbonate spring is gradual.
5) No changes are observed in the pulse after the bathing both in the simple carbonate spring and in the fresh water at 37°C, but a remarkable increase is observed immediately after the bathing in “Unagi-yu” end in the fresh water at 44°C. It returns to the normal pulse after one hour.
6) The shortening of the circulation time induced by the hot spring bathing is more remarkably observed in persons with low blood pressure and in younger persons, and the fall in the blood pressure is more remarkable in persons with high blood pressure and in older persons.
7) The shortening of the circulation time induced by the hot spring bathing is more remarkable in persons suffering from articular rheumatism than in healthy persons.
The return to the normal circulation time is quickest in healthy persons, followed by those suffering from diseases of the stomach, and it is clearly slow in persons suffering from tuberculosis and from rheumatism.
