The World Health Organization (WHO) has a specific definition of burn-out. This guide sets that definition next to the National Institute of Mental Health (NIMH) description of depression, so you can see where each starts and ends. It is general education, not a diagnosis.

If you or someone you know is struggling or having thoughts of suicide, call or text the 988 Suicide & Crisis Lifeline at 988 or chat at 988lifeline.org. NIMH says: “In life-threatening situations, call 911.” For help choosing between the two, see 988 vs 911: when to call which.
WHO says burn-out is included in the 11th Revision of the International Classification of Diseases (ICD-11) “as an occupational phenomenon. It is not classified as a medical condition.” It defines it this way: “Burn-out is a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed.” WHO says it is characterized by three dimensions:
WHO adds that burn-out “refers specifically to phenomena in the occupational context and should not be applied to describe experiences in other areas of life.” Under WHO’s definition, exhaustion in other parts of life is outside what the word burn-out covers.
WHO’s burn-out definition points to chronic workplace stress. A separate WHO fact sheet on mental health at work is about workplace conditions and mental health in general rather than burn-out specifically. It says:“Poor working environments - including discrimination and inequality, excessive workloads, low job control and job insecurity - pose a risk to mental health.” It lists excessive workloads or work pace and understaffing among the psychosocial risks.
“There are effective actions to prevent mental health risks at work, protect and promote mental health at work, and support workers with mental health conditions.”WHO, Mental health at work
No official source we found says how burnout and depression differ or overlap. WHO’s burnout page does not mention depression, and NIMH’s depression page does not mention burnout. What we can do is set the two descriptions side by side. They come from two separate sources and neither one is comparing itself with the other.
NIMH also says certain medications and medical conditions, such as viruses or thyroid disorders, can cause the same symptoms as depression, and that a provider can rule these out with a physical exam, interview and lab tests.
NIMH says: “If you show signs or symptoms of depression and they persist or do not go away, talk to a health care provider.” It names a primary care doctor, psychologist or psychiatrist as options. If you see signs of depression in someone you know, NIMH says to encourage them to seek help from a mental health professional.

In the same fact sheet, WHO says preventing mental health conditions at work is about managing psychosocial risks in the workplace, and it recommends employers do this through organizational interventions that target working conditions and environments. Its examples of organizational interventions are providing flexible working arrangements and implementing frameworks to deal with violence and harassment at work. Separately, it lists manager training for mental health, which helps managers “recognize and respond to supervisees experiencing emotional distress.”
For individuals, WHO lists interventions to “build skills to manage stress and reduce mental health symptoms, including psychosocial interventions and opportunities for leisure-based physical activity.”

No official source we found compares them. WHO defines burn-out as resulting from chronic workplace stress, with three dimensions, and limits the term to the work context. NIMH says a depression diagnosis requires symptoms most of the day, nearly every day, for at least 2 weeks (one of the symptoms must be a depressed mood or a loss of interest or pleasure in most activities). NIMH says that if symptoms of depression persist or do not go away, talk to a health care provider.
Under WHO's definition, burn-out refers specifically to the occupational context and should not be applied to experiences in other areas of life.
NIMH says that if symptoms of depression persist or do not go away, talk to a health care provider. If you or someone you know is having thoughts of suicide, call or text 988 or chat at 988lifeline.org. In life-threatening situations, call 911.
