The 40Hz Brain Hack: Unleashing Potential Through Neural Entrainment

The human brain is a complex network of neurons that constantly communicate through electrical signals. Scientists have long sought ways to optimise brain function and tap into its full potential.

One fascinating technique that has gained attention is the 40Hz brain hack. This article explores the concept of neural entrainment at 40Hz and its potential benefits for cognitive enhancement and overall well-being.

40Hz Brain Hack

Understanding Neural Entrainment

Neural entrainment refers to the brain’s ability to synchronise its electrical activity with external stimuli. When exposed to rhythmic stimuli, such as visual or auditory cues at a specific frequency, the brain tends to align its neural oscillations to match that frequency. This synchronization phenomenon is known as entrainment.

The 40Hz Brain Hack

The 40Hz brain hack involves stimulating the brain at a frequency of 40Hz, also known as gamma frequency. Gamma waves are high-frequency brainwaves associated with various cognitive processes, including attention, memory, and problem-solving. By exposing the brain to external stimuli at 40Hz, researchers believe they can induce neural entrainment, leading to enhanced cognitive function.

The Research Behind 40Hz Brain Stimulation

Several studies have explored the effects of 40Hz brain stimulation on cognitive function. For instance, a 2019 study published in Nature demonstrated that exposing mice to light flickering at 40Hz improved their cognitive performance and reduced the accumulation of amyloid-beta plaques associated with Alzheimer’s disease.

In another study published in the journal Cell, researchers investigated the impact of 40Hz stimulation on human brains. They found that rhythmic visual stimulation at 40Hz enhanced gamma oscillations and led to improved working memory performance in participants.

Furthermore, a 2020 study published in Neuron showed that non-invasive 40Hz auditory stimulation improved memory recall in older adults. The participants demonstrated enhanced memory function immediately following the stimulation and even up to an hour later.

Potential Benefits and Applications

The 40Hz brain hack has potential benefits across various domains:

Cognitive Enhancement: Neural entrainment at 40Hz may enhance attention, memory, and problem-solving abilities. This technique could be beneficial for students, professionals, and individuals seeking to optimise their cognitive performance.

Neurological Disorders: Research suggests that 40Hz stimulation could have therapeutic potential for neurological disorders. It may help mitigate cognitive decline in conditions like Alzheimer’s disease and improve symptoms in disorders such as attention deficit hyperactivity disorder (ADHD) and Parkinson’s disease.

Mental Well-being: The 40Hz brain hack may have positive effects on mental well-being. Gamma oscillations are associated with positive mood and emotional regulation. Stimulating the brain at 40Hz could potentially alleviate symptoms of depression, anxiety, and stress.

Considerations and Future Directions

While the research on the 40Hz brain hack is promising, there are some considerations to keep in mind. The technique is still in the early stages of development, and more studies are needed to fully understand its long-term effects, optimal protocols, and potential risks.

Moreover, it is important to approach brain stimulation techniques with caution. Individuals should consult with healthcare professionals or experts in the field before attempting any form of brain stimulation, especially if they have pre-existing medical conditions.


The 40Hz brain hack represents an exciting frontier in cognitive enhancement and neurotherapy. By harnessing the power of neural entrainment at 40Hz, researchers are uncovering potential avenues to unlock the brain’s full potential. As further research unfolds, this technique may offer new possibilities for optimising cognitive function, promoting mental well-being, and managing neurological disorders.

Incorporating NMN into the 40Hz Technique: Enhancing Energy and Sleep Quality

When considering the integration of NMN into the 40Hz technique, it’s important to recognise the significant impact NMN can have on energy levels and sleep quality. By incorporating NMN, individuals can experience the following benefits:

Assisting with Circadian Rhythms: NMN has the potential to positively influence circadian rhythms, the body’s internal clock that regulates sleep-wake cycles. By supporting the proper functioning of circadian rhythms, NMN may help promote a more balanced sleep-wake schedule and improve overall sleep quality.

Enhancing Sleep Quality at Night: NMN supplementation has been associated with improvements in sleep quality. By optimising cellular energy production and supporting healthy brain function, NMN may contribute to a more restful and rejuvenating sleep, leading to increased vitality and mental clarity during the day.

Increasing Vitality and Energy Throughout the Day: NMN’s role in cellular energy metabolism and its ability to boost NAD+ levels can lead to improved vitality and sustained energy levels. By enhancing the energy production within cells, NMN may help individuals feel more energised and alert throughout the day, supporting productivity and overall well-being.

When combining the 40Hz technique with NMN, individuals have the potential to enhance the benefits of neural entrainment while simultaneously promoting optimal energy levels and quality sleep. It is important to note that individual responses to NMN may vary, and it is advisable to consult with a healthcare professional before integrating NMN into any supplementation regimen.
