What Does Fatigue Mean?

Fatigue typically indicates a higher degree of weariness than tired. Fatigue is defined by the Merriam-Webster Dictionary as “weariness or exhaustion from labor, exertion, or stress” and by the Oxford Dictionary as “extreme tiredness resulting from mental or physical exertion or illness.”

This term is more used in medical contexts when compared to tired. It is often considered as a symptom of another medical condition. Fatigue can be mental or physical; oftentimes both these conditions are experienced together. If a person is physically fatigued for a considerable period, he or she tends to be mentally fatigued as well.

Physical fatigue usually refers to the weakness in muscles or lack of strength, which makes it difficult to carry out the physical activities a person usually does (for example, climbing stairs, carrying grocery bags, etc.) However, if someone is mentally fatigued, he or she will feel sleepy and find it difficult to concentrate.
