Sleep should occupy about a third of our life. Often seen as a waste of time, it is of vital importance for our health and well-being, just like nutrition or physical exercise.

What are its exact functions? What are the sleep cycles? What are the repercussions of poor sleep or too short nights? How to improve it? How can diet and micro-nutrition help?

Brain waves - understanding and influencing them

The brain emits waves, the intensity of which is measured in hertz (Hz) - in other words, the number of oscillations per second. They can be visualized using an electroencephalogram. Thus, they reflect the mental state of the individual and are related to what the person is doing, thinking, feeling.

When the brain functions normally, the waves are in phase with the individual's behavior, his activity at any given time. As we saw in the article on sleep, for example, waves vary depending on the sleep cycle.

Generally, it is difficult to control the frequency of these brain waves. But, they can be influenced to reduce stress or improve sleep quality, for example.

There are several methods, including hypnosis or meditation, which both require a certain level of expertise. Another method, accessible to everyone, is that of binaural sounds.

Binaural sounds

Binaural sounds are sounds - listened to with headphones - whose sound content is the same but according to a different tone. For example, the same sound will be transmitted at 114 Hz in the right ear and 124 Hz in the left ear. The brain will analyze the information and then retain the difference between the two, i.e. 10 Hz. After a few seconds, it will calibrate its brain waves to the difference between the two, i.e. 10 Hz.

Thus, depending on one's objective and the desired state of consciousness, a wave will be recommended. To achieve deep relaxation, it is best to listen to binaural sounds related to Theta waves!

It is possible to listen to binaural sounds just before falling asleep, but also during the day, whenever you wish. It is recommended to listen to them for about 10 minutes a day. You will find playlists on Spotify, for example. And to learn more about the subject, visit the website of the Boa Project. At the origin of the project is Olivia Boa. A mother of 4 children, passionate about neurology and intrigued by the mechanisms of our brain, she has developed the concept of Boa Ocular Kinetics which combines ART and NEUROLOGY to interact with our stress and provide simple and effective solutions to lower our brain frequencies.
