12 Signs of Burnout (and How to Tell If You're Burnt Out or Just Tired)

For years I thought I was just busy.

Five hours' sleep. A business to run. People relying on me. A voice in my head saying "you're fine, keep going." I called it hustle. The tiredness coffee couldn't touch, lying awake at 2am replaying the day, snapping at the people I cared about: I explained every bit of it away.

That was burnout. I just didn't have a name for it until my body forced me to stop.

If you're reading this, part of you probably already suspects something isn't right. Here are the signs I look for, in myself and in the people I coach.

What is burnout?

The World Health Organization describes burnout as the result of chronic workplace stress that hasn't been successfully managed. It has three main features:

1. Exhaustion: feeling drained, depleted and empty
2. Mental distance: feeling cynical, detached or negative about your work (or your life)
3. Reduced effectiveness: struggling to focus and get things done the way you used to

In real life, burnout doesn't only come from work. Caring for children or parents, running a home, a business and everyone's emotions can burn you out too.

12 signs of burnout

Physical signs

1. You wake up tired, even after a full night's sleep. Rest doesn't refill the tank anymore.
2. You can't switch off, even on days off or on holiday.
3. You keep getting ill, run down, or living on adrenaline and caffeine.
4. Your body is talking: headaches, tight shoulders, stomach issues, skin flare-ups.

Emotional signs

5. You're more irritable or snappy than you used to be, often with the people you love most.
6. You feel guilty when you rest.
7. You feel alone, even though you're never alone.
8. You don't feel like yourself anymore. This is the one I hear most.

Behavioural signs

9. You've stopped doing things you used to enjoy.
10. You're just getting through the day, not living it.
11. Your focus and memory aren't as sharp. You reread emails, forget things and make small mistakes.
12. You put everyone else's needs first, and you can't remember the last time you put yourself first.

Quick self-check

Score each of the 12 signs: 0 for never, 1 for sometimes, 2 for often, 3 for almost always.

• 0–9: early warning signs. This is the best possible time to act.
• 10–18: you're running on empty. Things need to change now, not "when things calm down".
• 19–27: you're likely burnt out. Start making changes today.
• 28–36: please get support, and speak to your GP.

This isn't a medical diagnosis. It's a way of being honest with yourself.

Why high-functioning people miss the signs

The people most likely to burn out are often the least likely to notice. They're capable, reliable and "fine". They're the glue holding everything together. Everyone leans on them, so nobody checks on them. And because they keep performing, they assume they must be OK.

Being drained isn't a willpower problem. It's a recovery problem. You can't out-push a body that needs to recover.

Burnt out or just tired?

Ordinary tiredness usually goes away with a good weekend, a few early nights or a holiday. Burnout doesn't. If you come back from a week off feeling just as drained, or dreading Monday by Saturday afternoon, that's a sign it's more than tiredness.

Always speak to your GP if you're constantly exhausted, to rule out things like anaemia, thyroid problems or vitamin deficiencies.

What to do next

1. Name it. Saying "I think I'm burnt out" out loud is the first step.
2. Do a bare-minimum week. Decide what must stay (your health, key work, the people who matter), and what can be dropped, delegated or delayed.
3. Protect one block of time a day where you're unreachable.
4. Fix your sleep first. Everything else is harder without it.
5. Get support. Burnout is very hard to fix on your own, because the habits that got you here feel normal.

Frequently asked questions

What are the first signs of burnout? Waking up tired after a full night's sleep, struggling to switch off, irritability, and losing interest in things you used to enjoy are often the first signs.

How long does burnout last? It depends on how long you've been running on empty and what changes you make. Recovery often takes weeks to months.

Is burnout a medical condition? The WHO classifies it as an occupational phenomenon rather than a medical condition. It overlaps with anxiety and depression, so speak to your GP if you're struggling.
