Sounds like hype: there's scant evidence the 'binaural beats' illusion relaxes your brain

Research conclusions on binaural beats

  • The authors played binaural or monaural (normal) beats to 16 participants, and recorded their brain activity with EEG.
  • They found both beats can entrain the brain to their particular frequency, but participants described no significant effect on their mood changes.
  • However, binaural beats can generate "cross-frequency connectivity," where the brain coordinates its activity across different types of brain waves.
  • It's then possible that binaural beats can be beneficial to some types of cognition, including memory recall.
  • An analysis of 35 studies demonstrated a modest effect on attention, memory, anxiety, and pain perception. However, these were not tested in the current study.

Binaural beats might affect our brains in some way

They may boost our attention span, calm our anxiety and promote pain relief, although evidence is still insufficient. Studies showed that the effects increased the longer people listened.

But whatever mechanism is creating these changes remains unknown.

How binaural beats work

You can hear these beats best with a pair of good headphones. When each ear picks up a slightly different pitch, the brain tries to compensate and finds a frequency somewhere in the middle. This supposedly causes both hemispheres of the brain to harmonize their brainwaves, a phenomenon called neural entrainment.

Brainwaves are the regular patterns that firing neurons create in our brains, so binaural beats could be bringing these rhythmic patterns into alignment (some research still debates this).

Exercise Benefits The Brain

Any kind of exercise, be it aerobic, walking or Yoga, changes the brain's composition, structure and the way it operates. The changes that happen to the brain:

Brain Waves increasing

The brain's electric impulses change, and the Beta waves increase during and after exercise, putting it in a better, more alert state.

More Sensitive To The World

Exercise makes our senses sharper and clearer, and we are more perceptive and have better sensitivity to our surroundings.
