Study of Cranial Electrotherapy Stimulation to Shorten Sleep Latency by Wearable Device
Objective:To investigate the efficacy of wearable sleep aid device based on cranial electrotherapy stimulation in shortening the sleep latency.Methods:A total of 241 individuals aged 18 to 80 years who used the device for at least four weeks were included.The sleep onset time of the individuals were calculated by the device,then sent back to the data center for analysis.Results:79.8%of the subjects after two weeks use shortened the sleep latency compared with the recordings of the first week.The average sleep latency decreased from(46.40±1.71)min in the first week to(34.22±1.46)min in the fourth week.Conclusion:There was a significant change of sleep latency before and after usage of the device,not directly related to the age and gender of the subjects.
