This study is for investigating various light-emitting diode dependence on stress response in flower arrangement activity by using heart rate, blood pressure, heart rate variability consisting of standard deviation of the normal-normal intervals, total power, ratio of the low and high frequency, and blood pressure. From the standpoint of the correlations among HR, HRV, and cortisol, the blue and green lights lead to an occurrence of significant difference going toward positive direction, indicating the considerable reduction of the stresses. These findings reflect that the methodologies and the results are very fruitful and effective to achieve a highly active horticultural therapy with the constructive assistance of LED lighting colors. |
