Burnout is not a medical diagnosis and it is not depression. It has six recognizable signs, and one rough test that tells the two apart.
Burnout has six recognizable signs, and the one that separates it from depression is what happens when you step away.
The World Health Organization defines burn-out as a syndrome that results from chronic workplace stress that has not been successfully managed. It is a response to a situation, not an illness of the person, and it builds gradually.
Below are the six signs, the difference from depression, and the five stages people move through without noticing the first two.
Six signs the tank is empty, not just low
Cleveland Clinic says you may not realize you have hit burnout until you cross the line between really tired and too exhausted to function. It lists six common signs.
Read them as a set. One on its own is a bad week.
- Fatigue that sleep does not fix. Cleveland Clinic calls fatigue the key symptom of burnout, and says you might feel like sleeping all the time, or find that simple tasks take longer to finish.
- Apathy that does not lift. Cleveland Clinic says everyone has days when they do not want to go to work, but with burnout those feelings persist. Mayo Clinic asks whether you question the value of your work and feel little satisfaction from it.
- A shorter fuse than usual. Cleveland Clinic says burnout changes how you feel and how you treat others, that you may be more irritable and on edge, and that small stressors may lead to frustration and angry outbursts.
- Eating and sleeping patterns shift. Cleveland Clinic says you may eat more or less than usual, or sleep more or less, or at different times. Mayo Clinic asks the same question about changed sleep habits.
- Tension headaches. Cleveland Clinic says prolonged stress leads to sleep problems and tensed muscles, and that this headache feels like pressure on the forehead and temples.
- Body complaints with no clear cause. Cleveland Clinic says burnout has been shown to cause back pain and gastrointestinal problems ranging from constipation to diarrhea. Mayo Clinic asks whether you have headaches, stomach or bowel problems with no known cause.
The WHO adds one limit worth keeping. It says burn-out refers specifically to the occupational context, and should not describe experiences in other areas of life.
The one test that separates burnout from depression
The World Health Organization says burn-out sits in an ICD-11 chapter about reasons people contact health services that are not classed as illnesses. It labels a situation, not a person.
Mayo Clinic agrees that burnout is not a medical diagnosis, and adds the part that matters. Burnout can raise the risk of depression, but the two are different and need different treatments.

Cleveland Clinic draws the practical line. Burnout is usually tied to a situation such as work. Depression does not always have a clear trigger. Stepping away from the source can often bring relief.
Its example is a trip. Away from the source of your burnout you can relax and enjoy the break. With depression, the symptoms travel with you.
Cleveland Clinic also says the two can resemble one another and can show up together. A clue, not a verdict.
Depression and burnout are different, and they need different treatments.

Cleveland Clinic says burnout develops gradually rather than all at once, and that providers often break it into five stages: a honeymoon phase, the onset of stress, chronic stress, burnout itself, and habitual burnout.
The first two are the ones people miss. In the honeymoon phase stress still feels manageable, and being busy feels like a point of pride. In the second, exhaustion and trouble concentrating get pushed through.

Mayo Clinic lists what it costs to do nothing. Feeling drained, not being able to cope or sleep, using more alcohol, and a higher chance of heart disease, high blood pressure or type 2 diabetes.
Its causes list reads as a diagnosis of the job rather than the person. Lack of control, unclear expectations, conflicts with others, too much or too little to do, and lack of support.
Three things people get wrong about burnout
Three beliefs keep people stuck, and each has a clear answer.
Burnout means you are weak. It means a situation went unmanaged, not that a person failed. The WHO defines burn-out as resulting from chronic workplace stress that has not been successfully managed. Mayo Clinic's causes list names lack of control, unclear expectations and lack of support. Those are conditions, not character.
A week off will fix it. A break helps and it is a useful test, but Cleveland Clinic says recovery takes work, and comes down to a meaningful daily routine and boundaries you create and maintain. Mayo Clinic says doing nothing makes the problems worse.
Burnout and depression are the same thing. Mayo Clinic says they are different and need different treatments, and that burnout can raise the risk of depression. Cleveland Clinic says they can resemble one another and can show up together. Two conditions, two treatments, one overlap.
