Evaluation of Physiological Effects Induced by Low Level Light Irradiation on the Acupoints of the Hand

"Experiment 1：Measure the heart rate parameters before, during, and after laser acupuncture or LED light therapy within a 25-minute experimental period, and observe the changes in the subjects' meridian energy before and after the treatment, followed by analysis. Acupoint selections mainly include Daling, Neiguan, and Shenmen.~Experiment 2：randomly assigns subjects to wear either a low-energy LED device or a sham device. The indicators, duty cycles, and sounds of the low-energy LED device and the sham device are all the same.~Experiment 3：Place light sources of different wavelengths on the earlobes or auricles of subjects with different skin tones. By observing the changes in light power before and after, the investigators can infer the effects of skin tone on light attenuation and transmission of light sources with different wavelengths."
