This Is Your Brain On Overwhelm.
According to research from Neuroscientist, Amy F.T. Arnsten, when you are overwhelmed, it is because you are soaking in high amounts of stress on the prefrontal cortex of the brain.
That’s the brain region that is the most sensitive to the detrimental effects of stress exposure. Even mild uncontrollable stress can cause a rapid and dramatic loss of prefrontal cognitive abilities.
