What exactly is brainwave entrainment?
Well, it’s exactly what it sounds like… training the brainwaves to change to a different frequency and induce different states of alertness or relaxation. The brain operates on a number of different frequencies throughout the day, from gamma and beta while you are awake and alert to theta and delta as you move through the various stages of sleep. It has been found that introducing minimally differing frequencies in each ear through the use of headphones can produce a single frequency in the brain which represents the difference between the two. For instance, if you were to listen to a 420 Hz frequency in the left ear and a 430 Hz frequency in the right ear, the brain would combine the two in to a single 10Hz frequency. This is the principle behind binaural beats, one of the simplest and easiest forms of brain entrainment. And what does this kind of brainwave entrainment actually achieve? For those individuals who have difficulty shutting down and relaxing at the end of the day, it can
