How can I return silence to my mind?

We live surrounded by noise. Not just from traffic or notifications, but the one that goes unheard: mental noise. That feeling of having thousands of thoughts at the same time, of not being able to “turn off” the head even when the body is exhausted. And although we have normalized it, this excess of brain activity has a clear biological cause: an imbalance in the neurotransmitters that regulate calm, among them, the protagonist of this article: GABA.

Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter of the central nervous system. In simple terms, it acts as a neural traffic regulator, preventing the brain's electrical impulses from becoming saturated. When GABA functions properly, thoughts flow in order; when it doesn't, the mind speeds up, sleep becomes fragmented, and the body enters a state of permanent “alert.”

The fact that few know

Studies from the National Institute of Health (NIH) have shown that people with generalized anxiety or insomnia have GABA levels up to 30% lower than those who sleep and rest well. This chemical difference explains why some can relax easily while others feel that their mind never stops, even in silence.

Relaxation is not laziness: it is brain chemistry

GABA acts as a natural “reset button.” It favors the transition of the brain from beta waves (alertness) to alpha and theta (relaxation and restorative sleep). Additionally, it helps reduce muscle tension and improves emotional stability.
A curious fact: the body can naturally increase its production of GABA through meditation, conscious breathing, or moderate exercise, but in times of chronic stress, nutritional support can make a difference.

GABA supplements, especially when combined with B complex vitamins, act as allies of the nervous system, helping to balance brain rhythm and regain a sense of calm and mental focus without causing excessive drowsiness.
