The Impact of Warm Water Immersion on Students’ Heart Rate, Blood Pressure and Self-Reliance
Leiu Laar, Kirkke Reisberg
Abstract The purpose of the current study was to evaluate the impact of warm water immersion of different durations on the cardiovascular system. The study was performed on 13 female volunteers, aged 20-25 years. Two warm water (38˚ C) bathing procedures of different durations (15 min. and 30 min.) were performed on separate days. Heart rate, blood pressure and self-reliance were registered before and 10 minutes after the bathing procedure. Based on the outcomes the following conclusions were made: 1. After warm water immersion procedures heart rate increased and blood pressure decreased significantly. A long-term bathing procedure had a more pronounced effect on heart rate and systolic blood pressure compared to the effects of a short-term bathing procedure. The effects of water immersion procedures were mostly of short duration, although blood pressure values were sustained at a lower level compared to the initial values. 2. General self-reliance of subjects did not change significantly after bathing. After short-term water immersion there was a significant increase in dizziness and feeling of weakness compared to the initial values. After long-term water immersion there was a significant increase in dizziness, feeling of weakness and heart beating compared to
