Brief Summary
Introduction In the past, it was found that stimulating the meridians and acupoints with low-level light often had a good effect. However, for safety reasons, most instruments such as laser acupuncture devices still need to be used by medical personnel, and it is difficult to apply to insomnia patients at bed-time or the first sleep cycle, these two periods have a considerable impact on sleep quality. Therefore, the purpose of this study is to provide a safer wearable light-therapy device for Insomnia patients, so that it can be used in home sleep situations, and the improvement of subjects' sleep qualtity and meridian energy will be evaluated by PSG, HRV parameters, sleep questionnaires, and Ryodoraku value (reflects the meridian electric resistance). Methods Aim1: To evaluate whether the subjects are more relaxed by observing the changes in heart rate and meridian energy of healthy subjects after low-level light irradiating to Shenmen, Daling, Neiguan (acupoints for insomnia). We also consider the difference of light source and the skin color in experiment design. Aim2: To assess whether the insomnia patients' sleep quality has improved after applying the wearable light therapy device to subjects' bed-time (include the first sleep cycle). We use PSG, sleep questionnaires, stroop test for evaluation.

Outcome Measures
Primary Outcomes (2)
Differences in sleep EEG before and after the laser irradiation compared to the sham group
According to sleep EEG,we can analysis participants' brain waves (alpha,beta,theta,delta) and sleep stages,etc. to evaluate their objective sleep quality
Change from Baseline sleep EEG at 67 days
Differences in Heart rate variability before and after the laser irradiation compared to the sham group
HRV is measured by the variations in the R-R interval between the successive peaks of the QRS complex in the ECG wave. Based on fast Fourier transform, time-domain (R-R interval) transfer to frequency domain resulting total power (TP, 0.04-0.15), low frequency (LF, 0.06-0.6Hz), high frequency (HF, 0.6-2.4Hz), normalized LF (LF%) and LF/HF ratio are obtained. LF% and HF represent an index of sympathetic activity and parasympathetic activity respectively. LF/HF is indicative of the sympathetic to parasympathetic autonomic balance.
Change from heart rate variability parameters at 67 days
Secondary Outcomes (8)
Differences in the Epworth Sleepiness Scale (ESS) before and after the laser irradiation compared to the sham group.
Change from Baseline ESS at 67 days
Differences in Visual Analogue Scale (VAS) before and after the laser irradiation compared to the sham group.
Change from Baseline VAS at 67 days
Differences in scores of stroop test before and after the laser irradiation compared to the sham group.
Change from Baseline score of stroop at 67 days
Differences in the Insomnia Severity Index (ISI) before and after the laser irradiation compared to the sham group.
Change from Baseline ISI at 67 days
Differences in the Pittsburgh sleep quality index before and after the laser irradiation compared to the sham group.
Change from Baseline PSQI at 67 days
- +3 more secondary outcomes
Study Arms (2)
laser group
ACTIVE COMPARATORLaser group use specific wavelength to light the sleep acupoints during. If the laser group take light acupuncture in the first month, and then become the sham group in the next month, vice versa.
sham group
SHAM COMPARATORsham group use the same divce and acupointsas the laser group, but the light is just a regular light. If the laser group take light acupuncture in the first month, and then become the sham group in the next month, vice versa.
