Today many people are running everywhere and stress is a part of daily routine. Many try to downplay it, but according to new research from the Youth Development Institute at the University of Georgia (United States), Stress may not be all bad for brain function,
This has been revealed in the study published in the scientific journal ‘Neuropsychology’. Low to moderate stress levels improve working memory. This is short-term information that people use to perform everyday tasks such as remembering someone’s phone number or remembering directions to a certain place.
not all advantages
However, the researchers caution. The results are typical for low to moderate stress. Once stress levels rise above moderate levels, it becomes constant and toxic. ,The negative consequences of stress are quite clear, and they are not new.“, said Asaf Oshari, lead author of the study.
High and sustained stress levels may change brain structure, There is an increase in white matter at the expense of gray matter, which is involved in muscle control, decision making, self-control, and emotional regulation, among other things.
chronic stress can also make people Susceptible to many maladies ranging from nausea and migraines to high blood pressure and heart disease.
little explored area
“But less is known about the effects of more limited stress. Our findings suggest that stress levels perceived stress, low to moderatewere associated with a higher neuronal activation of working memory, which translates into a better mental performanceOshri said.
In previous research, Oshri and colleagues showed that these Stress levels can help individuals build resilience and reduce the risk of developing mental health disorderssuch as depression and antisocial behavior. That study also showed that limited episodes of stress can help people cope with future stressful situations.
The present study builds on this previous work. Additionally, it has been complemented with magnetic resonance imaging (MRI) which proves those claims.
The results showed that those who reported low to moderate stress levels had greater activation in the parts of the brain involved in working memory. Participants who reported experiencing high and chronic stress levels showed decreases in those areas,
