Mental Stamina

Meaning

Mental stamina refers to the sustained capacity of the brain to maintain cognitive function, focus, and effective decision-making over prolonged periods, particularly when facing stress, fatigue, or demanding tasks. This neurophysiological attribute enables individuals to persevere through intellectual challenges, regulate emotional responses, and sustain productivity without significant decline in performance or well-being. It represents the brain’s enduring ability to allocate and manage attentional resources, process information, and execute complex operations consistently.
