This study aimed to investigate the effect of different light-emitting diode (LED) on the stress response of workers before and after a flower arrangement (FA) activity. Participants were 16 office workers who performed FA under 7 out of 8 LED lighting conditions: darkness, white (at correlated color temperature of 4,500 K), red, blue, green, magenta, cyan, and yellow; no FA is performed in the darkness condition. To identify significant differences among the different lighting conditions, the heart rate (HR), blood pressure (BP), heart rate variability (HRV) consisting of standard deviation of the normal-normal intervals (SDNN), total power (TP), ratio of the low and high frequency (LF/HF), and blood pressure were measured before and after FA. The salivary cortisol level was analyzed immediately after FA. The correlations among HR, HRV, and cortisol showed that the blue and green lights positively affected stress-responses and caused considerable reduction of stress. However, there was only a minor significant difference among other lighting colors, although individual lights may impact one or more parameters. These findings reflect that the methodologies and results of this study can be effectively used to achieve a highly active horticultural therapy with the constructive assistance of LED lighting colors.
