The Hidden Cost of an Unwell Team: What Every Australian Business Leader Should Know

By Michele Chevalley Hedge, Nutritionist  |  A Healthy View

I want to talk about something most organisations aren't measuring — but almost all of them are paying for.

It doesn't show up clearly on a P&L. There's no line item for it in the budget. And yet, for most Australian businesses, it is one of the single largest drains on productivity, team cohesion, and leadership effectiveness.

I'm talking about the physiological cost of an unwell team.

What presenteeism is actually costing you

Most leaders are familiar with absenteeism — people not showing up. It's measurable, visible, and organisations have systems to manage it.

Presenteeism is different, and it's far more expensive. Presenteeism means your people are physically at their desks but cognitively and emotionally absent. They're fatigued, foggy, running on caffeine and stress, unable to think clearly, make good decisions, or sustain the kind of focused effort that actually moves things forward.

Research from Medibank Private estimated that presenteeism costs the Australian economy approximately $34 billion per year — more than twice the cost of absenteeism. A study from the Integrated Benefits Institute in the US found that lost productivity from presenteeism was five times higher than losses from absenteeism.

These aren't edge cases. This is the baseline reality for most Australian workplaces.

Why it's largely physiological

Here's what I want leaders to understand — and this is the piece that most wellbeing programs miss entirely.

The symptoms of presenteeism — fatigue, poor concentration, irritability, poor decision-making, emotional reactivity, inability to sustain effort — are not primarily psychological. They are physiological. They are the direct result of what people are eating, how they are sleeping, how their stress hormones are functioning, and whether their blood sugar is stable enough to support consistent cognitive performance.

A person running on disrupted sleep, blood sugar spikes and crashes, and chronically elevated cortisol will perform like a different human being compared to the same person with seven to eight hours of sleep, stable blood sugar across the day, and managed stress physiology. The research on this is unambiguous.

This is not about blame. Most people don't know what their body needs to function optimally. No one taught them. They've been told to work harder, sleep less, push through — and they've paid a physiological price that they're now carrying into the workplace every day.

What most wellbeing programs get wrong

I've delivered keynotes and workshops to hundreds of Australian organisations. And the conversation is often the same: wellbeing has been delegated to HR, a few initiatives have been put in place (a meditation app subscription, a fruit bowl, a yoga class), and leadership has moved on assuming the problem has been addressed.

It hasn't.

Not because those things have no value — they do, at the margins. But because they treat the symptom without touching the cause. A meditation app does not fix the fact that your senior leaders are sleeping five hours a night and running on cortisol. A yoga class at lunchtime doesn't compensate for three years of skipped meals and chronic blood sugar dysregulation.

What actually works is education. Specifically, education that helps people understand what is happening in their body, why, and what they can do about it — in practical terms that fit into a demanding professional life.

When people understand why they crash at 3pm, they can make a different choice at 1pm. When they understand what chronic poor sleep is doing to their prefrontal cortex, they treat sleep differently. When they understand the relationship between cortisol, blood sugar and belly fat, the motivation to change becomes intrinsic — not driven by external pressure or guilt.

What this looks like in practice

The workplace wellbeing programs I run at A Healthy View are built around one central premise: give your people the science in plain language, with practical tools they can use immediately.

This means covering the specific things that drive performance and resilience at the physiological level: blood sugar management across the day, sleep architecture and what disrupts it, the stress-hormone-nutrition connection, how food choices affect cognitive clarity and emotional regulation.

It doesn't mean asking people to become health fanatics or overhaul their lives overnight. The most sustainable changes come from small, well-targeted interventions applied consistently — and from people who actually understand why they're making those changes.

Our programs are available as online courses that teams can access in their own time, or as live keynotes and workshops I deliver directly to your organisation. They are CPD accredited, evidence-based, and designed specifically for busy professionals in demanding roles.

A question worth sitting with

If your best marathon runner told you they were sleeping five hours a night, skipping meals, running on caffeine, and managing chronic stress with alcohol and sugar — you would intervene immediately.

The people running your organisation are doing exactly that. Every day.

The question isn't whether this is affecting performance. It clearly is. The question is whether your organisation is doing something meaningful about it — or whether wellbeing remains a line item in the HR budget that gets ticked and forgotten.

The organisations I work with that take this seriously see changes in team cohesion, leadership effectiveness, and sustained performance. Not because they spent more on wellbeing. But because they invested in the right kind of wellbeing — the kind that actually addresses the cause.

If you'd like to talk about what a meaningful workplace wellbeing program looks like for your organisation, I'd welcome the conversation.

Yours in good health and some dark chocolate. 🍫
