Brain health prevention is sometimes overlooked, and there is growing evidence of what we can do to keep it functioning.
Among the actions to avoid, a new study by the prestigious Stanford University, in the United States, emphasizes the complaint.
According to this study and as replicated by the Spanish site Telenueve, its effects would be more harmful than we thought.
The conclusion of this survey is that exposure to 30 minutes of disturbance per day can damage hippocampal neurons.. This would imply lower cognitive functioning, as this region is used for problem solving.
The effect would occur both in their own grievances and in someone close to them. The point would be in the action generated by negative thoughts.
It happens that in these situations, the Telenueve note continues, the brain releases neurotransmitters associated with stress and anxiety, such as cortisol and adrenaline. These can activate the body’s fight-or-flight response.which increases heart rate, blood pressure and muscle tension.
To arrive at this statement, the researchers in charge of the study used high-resolution magnetic resonance imaging (MRI) which allowed them to detect “links between stressful life experiences and long-term exposure to hormones produced during stress and, consequently , narrowing of the hippocampus.
Dr. Travis Bradberry is in the same line of thought. in his book How Complaints Rewire Your Brain for Negativity “How complaining rewires your brain for negativity” describes it constant negative expressions of discontent or anger generate a new configuration in the brain.
In this way, the brain understands that it is easier to be negative than positive.
