Brainwave Entrainment: A Novel Approach to Treating Insomnia

Insomnia, a condition characterized by disrupted sleep patterns, is a significant concern in a wide range of people, from those with medical conditions to psychiatric patients. The traditional treatment for sleep disorders has often been hypnotics or sedative medications. However, an alternative technique, Brainwave Entrainment, has shown potential to provide a new path to restful sleep by synchronizing brainwave frequencies with external stimuli (Shusheng et al., 2016).

In this innovative study, researchers utilized audio, visual, and haptic stimuli to enhance sleep quality in individuals with insomnia. Two distinct audio frequencies were delivered to the left and right ears, generating a binaural beat signal within the delta band. Concurrently, a visual input was administered through an eye-mask designed to block external light. A unique automated system was developed to exert controlled pressure at the HT-7 acupuncture point, which is associated with sleep regulation.

The therapy was self-administered by the study’s test group, all of whom had been diagnosed with insomnia. To assess the therapy’s effectiveness, brain signals were recorded before and after the treatment. For comparison, sleep patterns of subjects without insomnia (controls) were also studied.

The analysis revealed promising results: the average power of the delta signal increased by 10%, mirroring the control group’s levels. Additionally, a statistical analysis was conducted using Cohen’s d value, indicating significant improvements in sleep quality. Interestingly, subjects with insomnia who were not on oral medication showed better responses, with their rhythmic changes becoming almost identical to the control group’s. There was also a notable increase in REM state duration, reaching 20% of total sleep time, which aligns with recommended values.

In conclusion, Brainwave Entrainment through external sensory stimuli offers a potentially beneficial treatment for insomnia, especially when diagnosed early.
