According to the International Classification of Sleep Disorders, Third Edition (ICSD-3), insomnia is defined as <\/p><p>(1) Difficulty falling asleep, staying asleep, or waking up before the desired time;<\/p><p>(2) Sleep disorders that cause significant personal distress or impairment in daily life; and<\/p><p>(3) Sleep disturbances and associated daytime symptoms occurring at least three times a week over a period of at least three months.<\/p><p>Insomnia encompasses not only sleep disturbances at night, but also impaired daytime functioning, such as fatigue, attention and memory problems, impaired social, academic or occupational performance, and mood swings.<\/p><p>Furthermore, many studies have shown that people with insomnia have a higher risk of cardiovascular disease, chronic pain and type II diabetes.<\/p><p>Furthermore, the comorbidity rate of insomnia and other mental disorders is 41\u201353%.<\/p><p>After cognitive behavioural therapy for insomnia (CBTi), patients with comorbid mental disorders not only experience improved symptoms of insomnia, but also improved symptoms of their comorbidities.<\/p><p>Although the pathophysiological characteristics of insomnia are largely unknown, there is growing evidence that insomnia is a persistent condition and a complex disorder. A cohort study of 3,073 adults who were followed up annually over a period of 5 years confirmed that 41.6% of participants suffered from persistent insomnia. This finding suggests that early intervention could prevent the development of chronic insomnia and reduce the associated morbidity from sedatives and sleeping pills.  <\/p><p>Previous studies have shown that up to 13% of adults in the United States reported having taken benzodiazepines in the past year. Outpatient use of benzodiazepines has also increased significantly. Long-term use and overdose of sleeping pills can lead to side effects.  <\/p><p>Although guidelines for the treatment of insomnia include established recommendations for clinical practice regarding CBTi as first-line treatment, this treatment method has not yet become established in many countries. Furthermore, patient inconvenience and compliance with CBTi remain key issues in the implementation of this treatment. It is therefore important to investigate the effectiveness of other and newer non-pharmaceutical treatments for insomnia.  <\/p><p>In recent years, various non-invasive treatment methods for insomnia have been researched, including mindfulness therapy, acupressure, acupuncture therapies, cranial electrotherapy stimulation (CES) and repetitive transcranial magnetic stimulation (rTMS), etc. Another notable discovery of the last 20 years is that electromagnetic fluctuations in the environment, such as geomagnetic activity, can influence our physiology, psychology and behaviour. Earlier physical research showed that \u2018electroencephalographic performance showed certain correlations with the right parietal lobe for theta activity and the right frontal region for gamma activity.\u2019 Some studies have shown moderate correlations between an increase in geomagnetic activity and various behavioural consequences of brain activity.  <\/p><p>Wang et al. (2019) used an electroencephalogram (EEG) study and reported a strong, specific response of the human brain to ecologically relevant rotations of the Earth&#8217;s magnetic fields. After geomagnetic stimulation, there was a repeated drop in the amplitude of EEG alpha oscillations (8\u201313 Hz).  <\/p><p>In 1954, Winfried Otto Schumann reported on the existence of a natural extremely low-frequency field of approximately 7.83 Hz, known as the Schumann resonance frequency (SR), in the Earth&#8217;s atmosphere, which propagates electromagnetic waves (EMW) globally. 27 Its peak intensity can be detected at ~8 Hz, along with its harmonics with lower intensity at 14, 20, 26, 33, 39 and 45 Hz due to frequency-related ionospheric propagation losses. <\/p><p>The Schumann resonances found in both the global quantitative electroencephalographic activity of humans and the activity of the Earth&#8217;s ionosphere could indicate a causal relationship.<\/p><p>Furthermore, Ghione et al. found significant positive correlations between geomagnetic activity and systolic blood pressure (during the day and over 24 hours) as well as diastolic blood pressure (during the day, at night and over 24 hours). Burch et al. also found that increasing geomagnetic activity associated with elevated 60 Hz MF is associated with reduced nocturnal excretion of a melatonin metabolite in humans, meaning that EMF affects the human brain and sleep.    <\/p><p>In light of these findings, extremely low-frequency EMF Schumann resonance could improve human sleep. In this study, we use a sleep device with a \u2018Schumann resonance\u2019 function that emits the low frequency of the \u2018Schumann resonance frequency (7.83 Hz) wave\u2019 to resonate with the user&#8217;s brain waves, thereby facilitating falling asleep, reaching deep sleep and maintaining sleep. As the efficacy and side effects of \u2018Schumann waves\u2019 in the treatment of insomnia are still unclear, this study aimed to investigate the effects of Schumann resonance on insomnia symptoms through subjective and objective sleep assessments.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5beae3f elementor-widget elementor-widget-heading\" data-id=\"5beae3f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Materials and methods<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8c900e1 elementor-widget elementor-widget-heading\" data-id=\"8c900e1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Participants<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f73b764 elementor-widget elementor-widget-text-editor\" data-id=\"f73b764\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In this study, patients with insomnia were recruited through outpatient clinics at hospitals, and 46 participants met the inclusion criteria and took part in the study after giving their informed consent.

Only two participants suffered from side effects such as headaches and dizziness (study group n = 1; placebo group n = 1) and discontinued the study. This study is the first to investigate whether SR affects sleep and sleep disorders.  <\/p><p>In the SR sleep device group, both objective PSG measurements (SOL and TST, but not SWS) and subjective sleep measurements (SOL, TST, SE, sleep quality, daytime sleepiness, sleep satisfaction) improved significantly after using the SR sleep device. In the placebo device group, however, objective sleep measurements showed no differences after using the device, and there was only a subjective improvement in sleep in terms of sleep satisfaction and some components of the PSQI. <\/p><p>This result suggests that SR can reduce the symptoms of insomnia, particularly in terms of \u2018falling asleep\u2019 and \u2018total sleep time\u2019. Another important finding is that 55% of the placebo group showed improvement according to the PSQI and sleep satisfaction scale, which can be explained by the usual placebo effect in the treatment of insomnia. <\/p><p>At present, we do not yet fully understand the mechanism of SR in improving insomnia and sleep. Previous studies have shown that changes in geomagnetic activity are associated with epileptic seizures, myocardial infarction, stroke, and depression. Biogenic magnetite provides a molecular mechanism for geomagnetic perception that has been found in the human brain.  <\/p><p>Cherry (2002) suggested that SR, which propagates extremely low frequency (ELF) waves globally, is \u2018the possible biological mechanism\u2019 that explains the biological and health effects of geomagnetic activity on humans. The peak frequencies of SR are subject to moderate daily variation of approximately \u00b1 0.5 Hz. Interestingly, the first four SR modes happen to lie within the frequency range of the first four EEG bands (i.e., delta 0.5\u20133.5 Hz, theta 4\u20137 Hz, alpha 8\u201313 Hz, and beta 14 to 30 Hz).  <\/p><p>Some studies have also found that human brain waves and SR have the same frequency range. The human body recognises, absorbs and responds to natural EMF through the process of frequency resonance matching. Through this matching, natural EMF can influence biological communication phenomena in cell-to-cell communication in the human body. 44 Pall (2013) also reported that exposure to EMF would promote Ca2+ influx via the voltage-gated Ca2+ channel, which can increase Ca2+ concentration in the cytosol and then cause biological effects.45 Wang (2019) also pointed out that extremely low-frequency magnetic stimulation can induce low-frequency activities and lead to resonance effects in the human brain.    <\/p><p>The \u2018biophysical mechanism\u2019 for the mechanism of action on human health could explain the biological and health effects of geomagnetic activity. More and more psychiatrists are integrating electrophysiotherapy treatments into their clinical practice because they are non-invasive, have few side effects and can treat anxiety, depression and insomnia at the same time. Our findings on SOL improvement suggest that SR can resonate participants&#8217; brain waves with 7.83 Hz waves and relax their bodies, making it easier for them to fall asleep and increasing their total sleep time. Another hypothesis is that EMFs are related to human melatonin metabolites, which could also explain the improvement in participants&#8217; total sleep time and sleep quality after four weeks of treatment. However, this study did not show a significant increase in deep sleep percentage (SWS %). This could be related to the small sample size or the first-night effect of PSG. The four-week treatment period may be too short or may not yet have an effect on melatonin. Therefore, these results and hypotheses require more rigorous and long-term investigation. A recent systematic review and meta-analysis of CBTi showed significant effects on daytime symptoms, including daytime sleepiness, although the effect size is only small to moderate. By improving night-time symptoms, CBTi may have a positive indirect effect on daytime symptoms. Similarly, the SR sleep device group in this study had a significant effect on the severity of daytime sleepiness, meaning that SR can improve the quality of life of insomnia patients during the day (e.g., energy\/fatigue, physical pain, and mental health). In addition, Kay reported that SR improves depression.           <\/p><p>In addition to the potential benefits for sleep demonstrated by this study, further therapeutic effects of SR, such as improved daytime sleepiness and depression, as well as the role of SR in these correlated conditions, need to be further investigated. Although this is a randomised, double-blind design, there are still limitations. First, the sample size was very small (N = 40), although we did reach the estimated sample size (N = 38). Second, several patients had received hypnotics and were unable to discontinue them, but they maintained the same medications and doses throughout the study. Sampling errors may occur if we only include participants who are not taking medication. Thirdly, the \u2018first-night effect\u2019 should be taken into account when performing PSG, as it may explain the improvement in PSG. However, only the SR sleep device group showed a significant improvement in PSG, and this finding supported the effect of SR on sleep. Furthermore, we cannot truly verify compliance, but we did instruct our participants to turn on the device every night during the study period.       <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b95f0cb elementor-widget elementor-widget-heading\" data-id=\"b95f0cb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Conclusion<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4f3c22c elementor-widget elementor-widget-text-editor\" data-id=\"4f3c22c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>This study shows that SR can reduce the symptoms of insomnia, which is confirmed by both objective and subjective measurements, although the sample size is small.
