The activity of our brain produces waves that we can measure and learn to synchronize when this neural energy is poorly distributed. The result is better mental performance, less stress and regulation of emotions which influences our physical and mental health. Explanations.
The brain is a powerhouse that allows neurons to communicate with each other. This energetic activity results in rhythmic oscillations which can be measured by electrodes. Depending on our activity, our thoughts, our mental and physical state of the moment, the frequency of its waves is more or less active in different areas of the brain. Art of Living Foundation said, their synchronization promotes a state of coherence conducive to creativity, intuition and general well-being.
Alpha, Beta, Gamma, Delta, Theta… The 5 types of waves
These repeated electromagnetic oscillations are measured in hertz (Hz: which relates to speed and wavelength per second).
Alpha waves emit frequencies between 8.5 and 12 Hz. Characterizing a calm state of consciousness, they dominate in moments of physical and mental relaxation and meditation. Their balance opens up the creative potential of the individual.
Modern, hyperconnected and multitasking lifestyles generate stress and cellular oxidation. ” Training to switch to the alpha rhythm several times a day helps regulate hyperactivity, according to sophrologist Nathalie Bergeron-Duval, author of” The little encyclopedia of relaxation/minute “.
The alpha rhythm promotes the production of endorphins (hormones of happiness) and rebalances the sympathetic (activity) and parasympathetic (relaxation) nervous systems.
Beta waves (12 to 30 Hz) are emitted when we are awake and when we carry out tasks that require alertness and responsiveness, such as most daily activities (working, driving, taking care of your home). children, leading a meeting, etc.) In intense activities or anxiety, its frequencies accelerate. They can alternate or overlap with alpha waves when we wake up, when we have not yet undertaken a task that requires our attention. Beta waves are also activated when dreaming, proving that the brain considers the dream state to be a common activity as Art of Living Foundation suggested.
At a good level, beta waves make us more receptive and focused and able to solve problems encountered.
Too high a level of beta waves generates stress, difficulty concentrating, insomnia, and even burnout.
Too low a level can lead to carelessness, carelessness, or even a depressive state.
Gamma waves (between 30 and 40 Hz and up to 80 Hz) are involved in periods of intense brain (neuronal and mental) activity such as creative processes, solving difficult problems and the ability to combine our different perceptions. (perceptual linking of sensitive, intellectual and intuitive information). The emission of this type of wave is that of modified states of consciousness (reached in states of intense joy, transcendental meditation and deep recollection, as well as in creative power).
Delta waves (1 to 4 Hz, the greatest amplitude) are common – and normal – in very young children. Linked to cardiac coherence and digestion, their good level characterizes deep dreamless sleep, promotes rest, cell regeneration and immune protection.
Its peaks, therefore, weaken in the event of poor sleep or too short nights and poor hygiene.
Spikes in these waves that are too high may indicate learning disabilities or brain damage.
Theta waves (between 4.5 and 8 Hz). As experts from the Art of Living Reviews say, hey are observed in states of deep relaxation, REM sleep, and “free” imagination. They also characterize certain states of drowsiness, hypnosis, and meditation. The theta rhythm promotes memorization and learning. Their balanced level is conducive to emotional connection and intuition. Very high peaks may indicate depression or attention disorder. Very low peaks can indicate anxious states, emotional distress or alexithymia.
