Well yes, too I think I’m tired. At least that is what follows from a study conducted by researchers from the Salpêtrière University in Paris and published in a scientific journal. Current biologywhich highlights howintense and prolonged mental activity define accumulation glutamatesubstance potentially toxicin the prefrontal cortex, an area that manages decisions. According to scientists, one should avoid making decisive decisions at the moment of fatigue. Under these conditions, the brain will choose simpler estimates that require minimal effort. In short, when the brain gets tired, it moves on to easier tasks. From a series of minimum costs, maximum output.

How then to let the brain restore 100% functionality. First of all, it is necessary: ​​to bring the level of glutamate back to normal means to enable the brain to restore one hundred percent performance. And this is only achieved resting.

Why think too tired, study

To get these results, the researchers used magnetic resonance spectroscopy, a technique useful for monitoring brain chemistry throughout the day in two groups of workers. The former had to make important decisions, the latter had to perform simpler cognitive tasks. Fatigue arose primarily in a group of people with consistent mental activity. In addition, this group preferred those solutions that allowed them to quickly and effortlessly get results. The researchers noticed how these people glutamate levels in the prefrontal region of the brain were high. Glutamate is a neurotransmitter, a signaling molecule that transmits nerve impulses between nerve and muscle cells, and synapses are the contact points where this transmission occurs. High levels of this substance make cognitive control difficult. after a hard working day.

results

Researchers attribute mental fatigue to signal a brain that shuts down to get rid of excess glutamate. There is no way around this limitation, but rest can be a good remedy. According to scientists, our body removes glutamate during sleep. In short, when you take an afternoon nap or carve out a few hours of realx, don’t feel too guilty. (Good) rest is the most beautiful and useful gift we can give ourselves*.
