i-Dosing is actually a variation on a very old method of achieving an altered state.
In 1839 German physicist Heinrich Wilhelm Dove found that two tones played at slightly different frequencies in each ear makes the listener think they are hearing a quick beat.
He called the phenomenon ‘binaural beats’, and it has been the subject of research in the two centuries since.
Binaural beat therapy is used in clinical settings to research hearing and sleep cycles, to induce various brain wave states, and treat anxiety.
Dr Helane Wahbeh, a Naturopathic Physician and Clinician Researcher at the Oregon Health and Science University, said: 'Binaural beats happen when opposite ears receive two different sound waves.
‘And normally, the difference in sound between each ear help people get directional information about the source of the sound.
‘But when you listen to these sounds with stereo headphones, the listener senses the difference between the two frequencies as another beat that sounds like it's coming from the inside of the head.’ ~ read more
