Overview

The word fatigue is used in everyday living to describe a range of afflictions, varying from a general state of lethargy to a specific work-induced burning sensation within one’s muscles. It can be both physical and mental. Physical fatigue is the inability to continue functioning at the level of one’s normal abilities[1][2][3]. It is ubiquitous in everyday life, but usually becomes particularly noticeable during heavy exercise. Mental fatigue, on the other hand, rather manifests in somnolence.
