Burnout is exhaustion caused by long-term work stress that hasn’t been managed. The World Health Organization describes three signs: feeling drained, becoming cynical or detached from your job, and getting less done. Recovery means reducing the stress at its source, not just resting, plus sleep, movement, support and, often, help from your GP or employer.
Below: the symptoms of burnout, how it differs from stress and depression, the stages people describe, how to recover, and when to get help.
What is burnout?
The World Health Organization’s disease classification (ICD-11) describes burnout as a syndrome resulting from chronic workplace stress that has not been successfully managed. It isn’t classed as a medical condition but as an “occupational phenomenon”, and it refers specifically to work. People also use the word for caring, parenting or study, and the experience can feel very similar.
It’s common. The Health and Safety Executive estimates that 964,000 workers in Great Britain had work-related stress, depression or anxiety in 2024/25, with 22.1 million working days lost.
Burnout symptoms
| WHO sign | What it can feel like |
|---|---|
| 1. Exhaustion | Tired all the time, even after a weekend or holiday; dreading Monday; getting ill more often |
| 2. Mental distance and cynicism | Feeling detached, numb or negative about work; irritability with colleagues or customers |
| 3. Reduced effectiveness | Struggling to concentrate, making mistakes, feeling you’re achieving nothing |
Other common signs include poor sleep, headaches, brain fog, relying more on caffeine or alcohol, and pulling away from friends. See brain fog and anxiety at night.
Burnout vs stress vs depression
| Stress | Burnout | Depression | |
|---|---|---|---|
| Feels like | Too much: urgency, pressure, overdrive | Not enough: empty, drained, detached | Persistent low mood and loss of interest in most things |
| Linked to | Any pressure | Work (or another long-term role) | Life generally, not just work |
| Improves with a break? | Usually | Briefly, then returns | Often not |
| Needs | Better stress management | Changes at work, rest and support | A GP; it’s a treatable medical condition |
They often overlap. If low mood spreads beyond work or lasts more than 2 weeks, talk to your GP.
The stages of burnout
You’ll often see burnout described in stages. These models come from psychology writing rather than the WHO definition, but many people recognise themselves in them:
- Enthusiasm: high energy, taking on lots, working long hours.
- Mounting stress: some days feel harder; sleep and exercise start to slip.
- Chronic stress: constant tiredness, irritability, more caffeine or alcohol, withdrawing from people.
- Burnout: exhaustion, cynicism, feeling you can’t cope; physical symptoms.
- Habitual burnout: it becomes your normal, with a real risk to mental and physical health.
The earlier you act, the quicker the recovery.
What causes burnout?
- a workload that’s too high for too long
- little control over how or when you work
- lack of support or recognition
- unclear expectations or constant change
- poor relationships or conflict at work
- work that clashes with your values
- no recovery time: always on, emails at night, skipped holidays
How to recover from burnout
| Step | What it looks like |
|---|---|
| 1. Name it | Admit to yourself, and someone you trust, that you’re burnt out |
| 2. Reduce the load | Talk to your manager about workload, deadlines and priorities. Rest alone won’t fix it if nothing changes |
| 3. Protect sleep | A fixed wake time and a proper wind-down. See how to fall asleep fast |
| 4. Set boundaries | A clear finish time, notifications off in the evening, a real lunch break. See the Sunday scaries |
| 5. Move every day | Walking counts. Exercise is one of the best-proven ways to handle stress |
| 6. Reconnect | Time with people and activities that have nothing to do with work |
| 7. Calm your body | Short breathing breaks during the day. See nervous system regulation |
| 8. Cut the crutches | Ease off late caffeine and evening alcohol. See caffeine and anxiety |
Recovery usually takes weeks to months, not days. Be patient, and expect ups and downs.
Food and supplements play a supporting role. Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function. See how to lower cortisol naturally and stress in men.
Talking to your employer
- In Great Britain, the HSE says employers have a legal duty to protect workers from stress at work by assessing the risks and acting on them.
- Ask for a meeting with your manager, HR or occupational health. Bring specific examples and suggestions, such as a lighter workload, clearer priorities or flexible hours.
- Check whether your employer has an employee assistance programme (EAP), which often includes free counselling.
- If you need time off, your GP can give you a fit note, which can also suggest changes to help you return.
When to see your GP
See your GP if you’re struggling to function, sleeping badly for weeks, feeling low or anxious most days, or relying on alcohol or other substances to cope. In England you can refer yourself to NHS Talking Therapies. If you ever feel unable to keep yourself safe, call 999, or Samaritans on 116 123 at any time. See also World Mental Health Day.
FAQs
What are the symptoms of burnout?
The WHO describes three: exhaustion, feeling detached or cynical about work, and reduced effectiveness. Poor sleep, brain fog and irritability are common too.
Is burnout a medical condition?
The WHO classes it as an occupational phenomenon rather than a medical condition. It can lead to anxiety or depression, which are medical conditions.
How long does it take to recover from burnout?
Usually weeks to months. It depends on how long you’ve been burnt out and whether the causes at work change.
Can you get signed off work for burnout?
Your GP can give you a fit note if stress or its effects mean you can’t work, or suggest changes to help you stay in work.
What is the difference between burnout and depression?
Burnout is tied to work and often eases with changes there. Depression affects all areas of life and needs a GP’s help.
