kiệt sức
/ˈbɜːnaʊt//ˈbɜːrnaʊt/The term "burnout" originated in the 1970s, initially in the context of **substance abuse** and **addiction**. It was later adopted by **Herbert Freudenberger**, a psychologist, to describe the state of **emotional, physical, and mental exhaustion** experienced by **helping professionals**, specifically **psychotherapists**. This shift in meaning reflected the growing awareness of the toll that helping professions took on individuals. The term quickly gained popularity and expanded to describe the feeling of exhaustion and disillusionment in any demanding or stressful field, eventually becoming a recognized term for **work-related stress**.
