Cognitive Fatigue
Cognitive fatigue is the state of mental exhaustion resulting from prolonged mental effort, such as decision-making, problem-solving, or sustained attention. In our hyper-connected modern lives, it's often amplified by constant notifications and information overload, leading to impaired focus and increased error rates in tasks that demand high cognitive resources.
Did you know?
A 2010 study published in the Journal of Experimental Psychology revealed that cognitive fatigue can impair decision-making accuracy by as much as 40% after just two hours of intense mental work, equivalent to the effects of sleep deprivation. This phenomenon highlights how the brain, like a muscle, has limited energy reserves that deplete over time, often leading to surprising lapses in judgment even in highly skilled individuals.
