Biologically, there are 3 neurotransmitters in our body that work to help us “pay attention” or focus. Acetylcholine helps us determine what is “noise” and what is important. Dopamine helps with motivation and determining effort. Norepinephrine helps with being alert and staying on task. Additionally, just like our computers, we have a finite amount of working memory and running too many programs at once impacts outcomes. Our brains need some basics to be at optimal performance. The basics are nutrition, exercise, sleep and rest.
What we are “feeding” our bodies plays a large part in how well our brain functions. Studies have found that deficiencies abound within our regular diets and supplements are often helpful to make up for some vacancies. According to an article in Psychology Today, October 2021, “The Juice of Concentration”, Omega 3 fatty acids (think cold water fish, nuts, yogurt) influence the efficiency of brain cell operations and signaling. They can also have an effect on how dopamine is used in our bodies.
