What causes burnout at work?
Burnout at work is rarely caused by workload alone. It is the result of three factors combining over time: low energy (caused by poor nutrition, skipped meals or dehydration), sustained high stress (from workload, lack of control, emotional demands or uncertainty), and insufficient recovery (not giving the nervous system enough genuine rest to restore itself). When these three things occur together consistently, burnout risk rises significantly. Addressing burnout means looking at all three areas — fuelling the body properly, understanding your stress load, and building real recovery into daily life rather than treating it as a special event.
The connection between energy, stress and recovery, and what you can do about it
Burnout has become one of the most talked-about topics in workplace wellbeing and yet it's still widely misunderstood. Most people assume it's simply the result of doing too much for too long. But the reality is more nuanced, and understanding that distinction is the first step toward actually doing something about it. This blog comprises information prepared by our resident naturopath Sara Jubb.
A common question from our clients is "I don't know why I feel so depleted. I'm not even doing anything that different."
The answer, more often than not, lies in three interconnected areas: resources, demand, and recovery.
Burnout is a formula, not a single cause
Think of it this way. When energy is low (through poor nutrition, skipped meals, or dehydration) we have fewer physical and mental resources available to cope with stress. When stress remains high for sustained periods, it increases our need for energy and recovery. And when recovery is insufficient (not just sleep, but genuine nervous system rest) stress accumulates and energy cannot be restored, even when we're technically "resting."
Put those three things together consistently, and burnout risk rises significantly. The workload itself is rarely the whole story.
Resource: Are you fuelling yourself properly?
Good nutrition is the foundation of sustainable energy — and it's one of the most underestimated factors in workplace performance.
Eating the right foods most of the time supports concentration, mood and emotional resilience. It helps the body manage stress, supports the immune system, and gives the brain the building blocks it needs to function well under pressure.
Five nutrition priorities make a meaningful difference:
Protein supports stable energy, focus and recovery. Aim to include a source with every meal.
Healthy fats from oily fish, avocado, olive oil and nuts. And are essential for brain health, mood and sustained concentration.
Smart carbohydrates think vegetables, whole grains, beans and fruit rather than refined snacks and sugary drinks to provide the brain and body with a steady, reliable source of fuel.
Gut health matters more than many people realise. The gut-brain connection influences mood, stress resilience, inflammation and even cognition. Probiotic foods like yoghurt, kefir and kimchi, alongside prebiotic foods like oats, garlic, leeks and bananas, are worth prioritising regularly.
Brain-supportive foods brightly coloured vegetables, leafy greens, berries, oily fish, nuts and olive oil to provide the nutrients that underpin focus, memory and long-term cognitive health. Try to eat the rainbow over the course of the week.
None of this requires perfection. It requires consistency.
Demand: How much stress are you actually under?
Stress isn't only about how much work you have. It's shaped by responsibility and decision-making, lack of control or autonomy, uncertainty, emotional demands, difficult relationships, and everything happening outside of work too.
Burnout risk increases when demands consistently exceed available resources and that imbalance can build quietly, over months, before it becomes visible.
One of the most valuable things anyone can do is learn to recognise the early signs of depletion: physical signals like low energy, poor sleep, frequent illness or tension headaches; mental signals like brain fog, difficulty concentrating or making decisions; and emotional signals like increased irritability, anxiety, or a growing sense of detachment from work.
Awareness creates the opportunity for earlier intervention. And the goal isn't to eliminate stress it's to build the capacity to navigate it and return to a balanced state more quickly.
Recovery: Are you replenishing what you're using?
This is where most people hit a wall. Recovery is not the same as rest. It's not a holiday, a good night's sleep, or an evening on the sofa. It's the active process of helping the body and mind shift out of a state of activation and back into balance.
The problem is that many of us are rarely fully off. Even when we stop working, we remain mentally and physiologically activated; still thinking about emails, scrolling devices, mentally planning, filling downtime with stimulation rather than stillness. Over time, the nervous system struggles to switch into genuine recovery mode. Sleep becomes less restorative. Stress hormones stay elevated. Focus, patience and decision-making decline.
Building what's called nervous system flexibility (the ability to move between activated and relaxed states more fluidly) makes a significant difference over time. And it doesn't require dramatic life changes.
Small moments of active rest, woven into everyday life, are enough to begin retraining the nervous system to recognise safety and recovery. Things like taking a genuine pause between meetings, stepping away from screens, doing one thing at a time, spending a few minutes in nature, or practising slow intentional breathing. These aren't indulgences. They're maintenance.
The takeaway
Avoiding burnout at work isn't about removing stress from the equation. It's about building the capacity to move through it — and recover from it — so that it doesn't accumulate into something more serious.
Fuel consistently, not perfectly. Prioritise real food foundations. Pay attention to your gut and your brain. Understand that stress is not something to be avoided but something to be navigated. And treat recovery as a daily practice rather than something you do when things get bad enough.
These are small shifts. But over time, they add up to something significant.
