Stress, burnout, anxiety: what's the difference?

What is stress?

Stress is the body and mind responding to something outside you. NIMH describes it as the physical or mental response to an external cause, and says it goes away once the situation is resolved [NIMH-STRESS-FACTSHEET-2020].

Think of the week before an appraisal cycle closes. Targets pile up. Your shoulders tighten and you sleep badly. Then the ratings are shared, the week ends, and your body slowly settles.

That settling is the clue. Stress has a cause you can usually name, and it tends to ease when the cause does.

What is anxiety, and when is it a disorder?

NIMH describes anxiety as your body's reaction to stress, and says it can occur even if there is no current threat [NIMH-STRESS-FACTSHEET-2020]. The rating is done, yet you still lie awake going over what might go wrong.

A disorder means a recognised condition where the anxiety is lasting and gets in the way of daily life. Worry before an interview is not a disorder. WHO estimates that 470 million people worldwide had an anxiety disorder in 2023 [WHO-ANXIETY-FACTSHEET-2026].

Only about one in four people who need treatment receive any [WHO-ANXIETY-FACTSHEET-2026]. Only a trained professional can tell you whether what you feel is an anxiety disorder. This page cannot, and nor can a quiz.

What is burnout?

Burnout is a word for what can happen after work stress goes on for too long. WHO describes it as a syndrome (a group of signs that tend to appear together) resulting from chronic workplace stress that has not been successfully managed [WHO-BURNOUT-ICD11-2019].

WHO names three parts [WHO-BURNOUT-ICD11-2019]:

• Feeling drained of energy or exhausted.
• Feeling distant from your job, or negative and cynical about it.
• Feeling less able to do your work well.

WHO classes burnout as an occupational phenomenon, not a medical condition [WHO-BURNOUT-ICD11-2019]. That means it describes what happens in the context of work. It is not a medical diagnosis, and it does not mean you are weak.

Picture a long commute, a team that has shrunk, and targets that keep rising. After a year, Sunday evenings feel heavy and a holiday no longer helps. Many people recognise this. It often arrives quietly, so you may not notice until someone points it out.

Burnout is also about work. Someone can carry a heavy load at home and still not be burnt out in this sense. The word names the link between a person and their job, and that is why the job is part of the answer.

Am I burnt out, or just tired?

Ordinary tiredness usually improves with rest. A good night's sleep, a weekend off or a short break lifts it, at least a little.

Burnout tends to stay. You rest, and the heaviness is still there on Monday. You may also notice the second and third parts WHO names: you feel distant from your work, and less able to do it well [WHO-BURNOUT-ICD11-2019].

None of this proves anything. Illness, grief, a new baby at home or a hard season in the family can leave anyone exhausted. If the tiredness will not lift, a doctor can look at the whole picture, including your sleep and physical health.

How do they overlap, and why does it matter?

They overlap because the body has one way to say "this is too much". Poor sleep, a racing mind, irritability and tiredness can show up in all three. The table shows how they usually differ. Real life is messier than a table.

	Stress	Anxiety	Burnout
Trigger	An outside cause you can usually name [NIMH-STRESS-FACTSHEET-2020]	Can occur without a current threat [NIMH-STRESS-FACTSHEET-2020]	Chronic work stress that has not been managed [WHO-BURNOUT-ICD11-2019]
How long	Eases once the situation is resolved [NIMH-STRESS-FACTSHEET-2020]	Can last beyond the cause	Builds over a long time
What it feels like	Pressure, tension, short temper	Ongoing worry, a body on alert	Exhaustion, distance from the job, feeling less effective [WHO-BURNOUT-ICD11-2019]
What often helps	Rest, routine, support, a change to the demand	Calming skills; a professional can assess if it lasts	Changes at work, plus rest and support [WHO-ILO-WORK-GUIDELINES-2022]
When to seek help	If it does not ease or affects daily life	If it lasts and interferes with daily life	If it is hard to get through the working day, or you feel hopeless

Why it matters: the answer depends on the story. Stress often needs a lighter load. Burnout often needs the work itself to change. Lasting anxiety may need a professional's help.

Burnout and low mood can also look alike, and a doctor or psychologist is the person to tell them apart. Do not rule yourself in or out.

What helps, in practice?

Small, steady things tend to help more than one big effort. NIMH suggests keeping a journal, trying relaxation or breathing exercises, exercising and eating regular meals, keeping a consistent sleep routine, limiting caffeine, and leaning on friends or family [NIMH-STRESS-FACTSHEET-2020].

For a tense moment, the NHS describes slow breathing: in through the nose, out gently through the mouth, counting from 1 to 5 each way if it helps, for at least five minutes [NHS-BREATHING-2026]. Some people find it takes the edge off. It is one tool, not the whole answer.

If you work from a shared home with no quiet corner, a walk after work or a few minutes on the terrace can do the same job. A voice note to a friend counts as leaning on someone.

For burnout, personal habits are not enough on their own. WHO says decent work is good for mental health, and that risks include long or inflexible hours, heavy workloads, little control, unclear roles and conflicting home and work demands [WHO-MHWORK-FS-2026]. WHO and the ILO recommend changes to the organisation and training for managers, not only individual coping [WHO-ILO-WORK-GUIDELINES-2022].

So if you are burnt out, the problem is not that you failed to be resilient. The workload may need to change. Our guide on talking about mental health at work offers words you could use.

When is it time to talk to someone?

NIMH points to professional help when severe or distressing symptoms last two weeks or more and get in the way of daily life [NIMH-DO-I-NEED-HELP-2025]. Daily life can mean getting out of bed, doing your job, eating, sleeping or enjoying anything.

It does not have to be at its worst. If you are unsure, that is already a good enough reason to ask. Our guide on when to talk to a professional explains who to see in India, what is free, and what to expect.

Free options come first. Tele-MANAS is India's national tele mental health programme. It is free, open 24x7 and available in 20 languages [PIB-TELEMANAS-2026]. The Help now page has the current number. If you share a home and a phone, a quiet corridor or a short walk can give you the privacy for a call.

A company may also run an employee assistance programme (EAP), a confidential counselling service paid for by the employer. Larger firms often have one. Check your intranet or ask HR whether yours does, because many people never hear about it.

If things feel unbearable right now, the Help now page lists free helplines you can reach today.

One small step

Tonight, write down one sentence about what feels heaviest. Is it a deadline, a worry that will not leave, or a tiredness that rest does not touch? You do not have to solve it. Naming it is a first step, and it gives you something to say if you decide to tell someone.
