Investigating the Efficacy of Theta Binaural Beat on the Absolute Power of Theta Activity in Primary Insomniacs.

Different people experience different brain waves based on the type of activity they do in their life at the same time. This brain wave pattern can change especially after a person decides to go to bed and experience an ideal sleep. Theta brain wave, which plays a role in important activities such as memory, deep relaxation, and day-dreaming, helps a person to change from wakefulness to sleep faster. Research literature has shown that people with insomnia have different brain waves than healthy people, especially in the theta brain wave. Accordingly, many interventions have been carried out to improve the sleep quality of these people and change their brain waves. It has been shown that binaural beat as a low-cost method based on sound waves, can change the brain waves of healthy people, but so far, no study has been done to investigate the effect of these sound waves (especially theta waves) on the brain waves of people with insomnia. The current study was conducted with the aim of investigating a non-invasive method (theta binaural beat) to improve the brain wave pattern of people suffering from insomnia. The findings of this study showed that theta binaural beat can be effective in changing the brain wave pattern of people suffering from insomnia.
