健常成人男性における高温浴前後の血液学的及び生理学的検査値の変動

抄録

To clarify the effects of full bathing at 42°C for 10min, we measured hematologic (white blood cells, red blood cells, hemoglobin, hematocrit, platelets, whole blood passage time) and physiologic (body weight, blood pressure, pulse rate) values of 10 healthy men aged 28 to 37 years. Data were collected before, immediately after, and 60min after bathing, and values were compared using a one-factor ANOVA.
No significant changes in hemotologic values were found among the three measurement timepoints. Regarding physiologic values, no significant changes in body weight and systolic blood pressure were found among the three measurement time-points. However, diastolic blood pressure decreased after bathing (53.0±9.8mmHg) compared with that before bathing (76.2±10.3mmHg), then increased again 60min after bathing (71.1±10.6mmHg) compared with that immediately after bathing. Furthermore, pulse rate increased significantly after bathing (101.3±10.3bpm) compared with that before bathing (69.0±5.9bpm), and then decreased significantly 60min after bathing (69.8±7.0bpm) compared with that immediately after bathing.
Our results indicate that hot water bathing does not influence hematologic values, body weight, or systolic blood pressure in healthy men. Although diastolic blood pressure and pulse rate changed significantly after bathing, they returned to baseline values 60min after bathing. The changes in hematologic and physiologic values may be explained by the maintenance of the body's homeostasis.
