40hz and focus

Using 40Hz binaural beats can significantly enhance focus and concentration. These beats involve listening to two slightly different frequencies in each ear, which are then integrated in the brain to stimulate cognitive performance. Research suggests they boost levels of dopamine and acetylcholine, key neurochemicals for focus. Several studies have indicated their effectiveness in improving reaction times, verbal recall, and overall cognitive function, particularly when used for a few minutes prior to a cognitive task or to maintain focus in distractible states 1 2.

For optimal use, Andrew Huberman recommends using 40Hz binaural beats for about five minutes before starting focused work or longer during states of high distractibility. He also suggests alternatives like white or brown noise for supporting cognitive performance 2 3.

To try this method, you can access apps like BrainWave or search for 40Hz binaural beats on platforms like YouTube for free options 1.
