Among the numerous neurotransmitters that influence our brain activity, GABA – gamma-aminobutyric acid – serves as a calming constant that helps us relax and enter a deep sleep.

GABA at a glance

As the main inhibitory neurotransmitter in the human central nervous system, GABA acts as a natural relaxant for our brain by inhibiting neuronal activity and promoting relaxation.

The connection to our sleep

The role of GABA in sleep cannot be overemphasized. A lack of GABA in the brain has been linked to sleep disorders and even insomnia . People who have difficulty falling asleep or whose sleep is restless often have reduced GABA levels . As night falls and our body prepares for sleep, GABA activity in our brain increases. This increase supports the transition from wakefulness to sleep and also plays a key role in maintaining deep, restful sleep.

Difference between GABA and other neurotransmitters

Neurotransmitters are chemical messengers in the brain that transmit signals between neurons. While neurotransmitters like serotonin and dopamine are often associated with positive feelings and activity, GABA plays a central role in calming the brain. It counteracts the excitatory effects of other neurotransmitters, helping to promote a state of relaxation and calm.
