Schumann Resonance and Insomnia

Sleep Improvement of Schumann Resonance in the Treatment of Insomnia-A Randomized and Double-blinded Study

The double-blinded and randomized study evaluated the effectiveness and side effects of a novel non-invasive treatment, Schumann resonance (SR), in treating insomnia. The objective of this study is (1) to evaluate the improvement of sleep quality of patients with insomnia disorder by SR and (2) to be the basis for the future development of physical magnetic therapy.

• Conditions: Insomnia
• Intervention / Treatment: Device: Schumann resonance sleep device; Device: Placebo sleep device

Detailed Description

Insomnia is a common sleep disturbance that affects the health and quality of life of individuals and accounts for considerable utilization of medical resources. The prevalence of insomnia is approximately 30%; in Asia, the prevalence of insomnia is approximately 4% in Japan, 9.9% in South Korea, 10.3% in Taiwan. Based on the statistic of Taiwan BNHI office in a 2013 report, there is worth of 1.3 billion prescriptions of hypnotic drug in one year. In addition, the reimbursement expenditure pays up more than 1 billion New Taiwan Dollars (NTD) with increasing expense rate of 15% every year, showing insomnia causes great distress to Taiwanese.

The characteristics of insomnia are difficulty with initiating or maintaining sleep, early morning waking, or non-restorative sleep. In DSM-5, the diagnosis of primary insomnia has been renamed insomnia disorder to avoid the differentiation between primary and secondary insomnia.

The most common treatment for insomnia is pharmacological therapy with hypnotics such as a benzodiazepine, zolpidem, or zopiclone. However, treatment with hypnotics includes the risk of adverse effects, drug tolerance and dependence . Some past reports on different non-pharmacological treatment strategies, such as Cognitive-Behavioral Therapy (CBT), muscle relaxation training, stimulus control, sleep restriction, and sleep hygiene, have demonstrated the effectiveness of most of these non-pharmacological treatments. However, the poor compliance and inconvenience for CBT is always a big issue.

Except the traditional treatment of insomnia, some folk therapies' clinical effect does not been confirmed, such as aromatherapy, music therapy, etc. Nowadays, due to development of technology for medical devices, some sleep devices were launched, aim to prolong the slow-wave sleep and enhances the sleeping quality.

The investigational device in this study is a sleep device with SRF (Sleep Restore Frequency), the principle is to integrate the bio-energy generated Schumann resonances, native from Earth, and the shocks from the Earth's magnetic field. Through the non-contact method with bio-energy waves, SRF are coupled to the sleep center of the brain, inducing and adjusting the electrical activities of the sleep center. It prolongs the in-depth sleep and enhances the sleeping quality.

The objective of this study is (1) to evaluate the improvement of sleep quality of patients with insomnia disorder by sleep device and (2) to be the basis for the future development of physical magnetic therapy.

Sample Size Approximately 60 subjects who meet the inclusion and exclusion criteria will be enrolled into the trial and averagely separated two arms for statistical analysis.

Statistical Analysis Efficacy evaluation statistics will be conducted with independent t-test or Fisher's exact test for testing the differences and conducted with Pearson correlation coefficient for the association between variables.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SR device group	Device: Schumann resonance sleep device; A Schumann resonance sleep device would stably output the composite frequency of a "the Schumann resonance frequency (7.83 Hz) wave, theta wave, and delta wave". The subjects were asked to use the device (place it next to the bed facing the subject's head, turn it on about one hour before going to bed every night, and turn it off after getting up the next day) every night for four weeks.
Placebo Comparator: placebo device group	Device: Placebo sleep device; A Placebo sleep device is an instrument with the same appearance and operation as the Schumann resonance sleep device, but does not output any frequency wave. The subjects were asked to use the device (place it next to the bed facing the subject's head, turn it on about one hour before going to bed every night, and turn it off after getting up the next day) every night for four weeks.
