Benefits of Brainwave Entrainment

Delta

Delta is the slowest brainwave level, associated with dreamless (non-REM) sleep. Essential for proper restoration of health and immune system.

Delta brainwave entrainment has been shown to:

  • Decrease mood disturbance, anxiety, tension, confusion fatigue and anger.
  • Improve sleep quality, duration of sleep, number of awakenings.

Theta

Theta brainwaves are associated with a deeper state of mindfulness, creative insight, cognitive & memory enhancement, and feelings of deep connectedness. Also, it’s the level at which people naturally progress into a sleep state.

Theta activity is associated with behaviors such as:

  • Relaxed attention
  • Working memory
  • Has been associated with long-term and working memory processes
  • Linked to improvements in cognitive performance
  • Linked to improvements in perceptual performance
  • During meditation, high theta activity is present in the brain but not in typical places.

Theta brainwave entrainment has been shown to:

  • Reduce anxiety
  • Significantly increase the number of words recalled post-stimulation
  • Help activate the parasympathetic nervous system
  • Increase phase synchronization at temporo-lateral synchronization
  • Openness and Conscientiousness personality traits may be more susceptible to entrainment in the Theta frequency ranges.

Alpha

Alpha brainwaves are associated with relaxed and calm mental activity, which people can otherwise achieve through relaxation exercises and meditation.

  • Alpha brainwaves do not represent cortical idling, it may in fact provide an index of neural efficiency.
  • Individuals classified as more intelligent exhibit greater levels of alpha power.
  • Induced increases in alpha power have been associated with improved attention processing

Alpha brainwave entrainment has been found to:

  • Induce an enhancement of heart rate variability in subjects with that reduced metric.
  • Increase creativity (divergent thinking).
  • Improve attention.
  • Reduce anxiety
  • Reduce severity of tinnitus

Beta

Beta brainwaves are associated with awake, normal levels of alertness. Increased beta activity is shown when attending to a stimulus and planning a response.

Beta brainwave entrainment has been shown to:

  • Increase performance in tasks related to verbal span, working memory, executive functions, and vigilance
  • Improved performance in psychomotor vigilance tasks
  • Increased response accuracies in visuospatial working memory tasks
  • Result in a decrease in negative mood.
  • Openness and Conscientiousness personality traits may be more susceptible to entrainment in the Beta frequency ranges.

Gamma

Gamma waves are often observed in the brain when a person is actively engaged in mental activity, such as learning, processing sensory input, or solving a problem.

They are associated with:

  • Higher-order cognitive processes such as attention, memory, and problem-solving.
  • Elevated gamma brainwaves are associated with the flow state.
  • The cortex has a tendency to produce gamma oscillations around 40 Hz, during conscious attention and perception.
  • Lucid Dreaming.
  • Advanced levels of meditation.

Gamma brainwave entrainment has been shown to:

  • Improve Alzheimer’s condition:
    • Reduce Alzheimer’s hallmarks (amyloid plaques, tau tangles), improved learning and memory in mice.
    • Combining gamma entrainment with exercise showed the best results in hallmarks reduction.
    • One-hour daily 40 Hz light and sound stimulation appears to help people with Alzheimer’s disease retain brain volume and cognitive ability.
  • Reduce anxiety.
  • Increase in cerebral blood flow.
  • Increase creativity (divergent thinking).
  • Increase attention control.
  • Improve cognitive flexibility.
