A novel device for foot reflexology that utilizes color light stimulation has been developed and the efficacy of the device has been tested as a basis study. The new foot color reflexology device is designed in a way so that color light can separately project red, orange, yellow, green, blue, and violet color lights to various neural reflex points on foot for a certain amount of time. The efficacy of the device was studied with seven young healthy subjects by measuring various physiological signals and foot related parameters before and after the treatment of the foot color reflexology. The measured physiological signals were bodily temperature, blood pressure, pulse rate, and heart rate variability(HRV). The measured foot related parameters were foot surface temperature, foot instep circumference, volume and peripheral plethysmograph(PPG). The results showed increase in bodily temperature, foot surface temperature and decrease in pulse rate, HRV, foot instep circumference, and foot volume. Therefore, the foot color reflexology seems to be effective in reducing stress and relaxing mind and body.
