The term "burn out" refers to a state of physical, emotional, and mental exhaustion that results from prolonged and excessive stress or workload. It often occurs in work or academic environments, where individuals feel overwhelmed, depleted, and unable to meet constant demands. Symptoms of burnout may include feelings of cynicism, detachment, reduced performance, and a sense of hopelessness.
The phrase "burn out" is derived from the combination of the verb "burn," which has its roots in Old English "byrnan," meaning "to consume with fire," and the word "out," indicating a finality or conclusion. The term evolved in the late 20th century to describe a decline in energy and enthusiasm, particularly related to work and stress.
