台灣溫泉資源相當豐富，相關的溫泉研究亦是不少，其中以探討溫度或泉質對於生理參數影響之研究較多，對自律神經的研究較少，故本研究想瞭解浸泡不同溫度和不同泉質浸泡時對人體自律神經以及生理參數之變化為何。受測者對象為20名18歲至25歲之間的健康自願者，以全身浸泡的方式分成不同溫度(32℃和41℃)以及不同泉質(單純泉、碳酸氫鹽泉和白磺泉)六種組別，並以心率變異分析儀和多參數監護儀進行心跳速率、血氧飽和度、呼吸頻率、血壓和心律變異等相關數值之前測，再依組別各浸泡15分鐘，浸泡結束後休息10分鐘再進行後測。數據以平均值±標準差(Mean ± standard deviation)和後/前的比值呈現，用配對t檢定(paired t-test)比較各組浸泡前後之差異，以及獨立樣本t檢定(independent t-test)比較相同泉質浸泡不同溫度之差異，並以P值小於0.05為顯著水準。研究結果發現，不同泉質及溫度的浸泡皆使心跳速率下降，其中41℃下降幅度較少，32℃下降幅度較多；32℃浸泡時收縮壓和舒張壓變化較不明顯，而41℃浸泡時收縮壓及舒張壓明顯下降；心率變異度(Variance)在浸泡後稍微增加但不明顯；交感神經活性(LF%)在32℃三種泉質中浸泡後無明顯變化，但在41℃中浸泡則明顯上升；浸泡41℃白磺泉使副交感神經活性(HF%)下降，其它則沒有明顯變化。綜合以上結果顯示，大多數受測者在浸泡溫泉後可能因為血管的擴張而降低了心跳速率和血壓，高溫(41℃)浸泡刺激交感神經活性(LF%)而上升，副交感神經活性(HF%)則無明顯變化或降低，並使心跳速率降幅減少，故泉溫對心跳、血壓、自律神經活性影響較大，泉質影響較不明顯。關鍵字：單純泉、碳酸氫鹽泉、白磺泉、血壓、心率變異性 Taiwan had rich hot springs resources and related researches, which had more studies on physiological effects by temperatures and springs, less on autonomic nervous system. Therefore, this study tried to explore the physiological and autonomic nervous effects by different temperatures and springs. Twenty healthy volunteers aging 18-25 were subjected to immerse in two temperatures ( 32℃ and 41℃ ) and three kinds of springs ( simple spring, bicarbonate spring and white sulphur spring ) for 15 minutes. Heart rate, blood oxygen saturation, breathing rate, systolic and diastolic blood pressure, heart rate variance were determined by multi-parameter monitor and heart rate variance analyzer before and 10 minutes after immersing. All data were presented by mean standard deviation and the ratio of post-values verse pre-values. Paired t-test was used to compare the difference of pre-values and post-values. Independent t-test was used to analyze effects of two temperatures with the same spring. The significant level was 0.05. The results showed decreased heart rate but more by immersing 32℃ than 41℃ springs. Changing of systolic and diastolic blood pressure were not obvious as immersing in 32℃ spring, and were significantly decline as immersing in 41℃ spring. Heart rate variance increased little without significance. Index of sympathetic activity ( LH% ) increase as immersing in 41℃ spring but not in 32℃. Parasympathetic activity (HF%) decreased significantly only immersing in 41℃. In conclusion, hot springs immersion caused heart rate and blood pressure decrease which may be due to vasodilatation. Higher temperature (41℃) stimulated sympathetic activity. Therefore, the effects of temperatures were greater than spring types on heart rate, blood pressure and autonomic nerve activity.Keywords: simple spring, bicarbonate spring, white sulphur, blood pressure, heart rate variance
