I was speaking with a senior leader recently who said, almost in passing, “I just assume from here it’s about slowing down and managing the slide.” There was no drama in it… just a quiet acceptance. And I hear that a lot. High performers, experienced leaders, people who have built incredible careers… but somewhere along the way they’ve absorbed the idea that their trajectory now only goes one way. The problem is… that belief doesn’t hold up when you actually look at the data.

What’s often missed is that it’s not just your 'average' recovery that matters… it’s how 'consistent' that recovery is. 🧠 The science here is evolving quickly. A recent large-scale study analysing nearly 2 million nights of data found that variability in heart rate variability (HRV) during sleep, not just the absolute value, reflects how stable (or unstable) your behaviours are (Grosicki et al., 2026 -  https://lnkd.in/dxm6aaqq ). Oh, and for fan boys like me,  Andy Galpin  

But the real shift is subtraction… not addition. We’ve overcomplicated something that is fundamentally biological. The human system didn’t evolve needing 17-step morning routines. It evolved needing rhythm, recovery, and enough space to function well. 🔬 The science here is surprisingly consistent: Chronic overload… whether cognitive, emotional, or behavioural… drives what we call allostatic load - The cumulative “wear and tear” on the body from doing too much, too often, wit

We tend to treat social connection as something that’s nice to have. It sits somewhere in the category of happiness or general wellbeing, but not quite alongside the things we take more seriously like sleep, nutrition, or exercise. And yet, when you step back and look at the data over time, that hierarchy starts to feel a little off. Some of the longest-running studies we have suggest that people with stronger, more meaningful relationships don’t just feel better, they actual

And the tricky part…they’ve normalised it. Early flights. Late emails. Broken nights. It becomes the cost of doing business…but the biology tells a very different story. 🧠 Sleep is not passive. It’s one of the most active recovery processes in the body. During sleep: • The brain clears metabolic waste via the glymphatic system • Emotional experiences are processed and regulated • Memory and learning are consolidated • Appetite hormones are regulated When this process is shor

Over the past decade, organisations have invested some $$$ in employee wellbeing. From mindfulness apps and resilience workshops to wellbeing challenges and yoga classes, many companies have tried to somewhat support the health and wellbeing of their people. The intention is almost always positive. Leaders recognise that wellbeing matters and that supporting employees is the right thing to do. Yet despite this investment, many organisations are still struggling to translate w

In boardrooms around the world, I see the same pattern. Leaders optimise schedules. Track metrics. Push productivity. Yet one of the most powerful performance levers is often overlooked… human connection. 🧠  The Science A growing body of peer-reviewed research shows that strong social connection is not just emotionally valuable… it is biologically protective. A landmark meta-analysis published in PLOS Medicine  found that people with stronger social relationships had a 50% g

It’s a question I hear more and more from leaders navigating their own health journeys. And new neuroscience is starting to provide a fascinating piece of the puzzle. Recent research has mapped, for the first time, where GLP-1 (the hormone mimicked by drugs like semaglutide and liraglutide)  is expressed in the brain… and the differences between males and females are striking. 🔬 The science Using a high-resolution technique called RNAscope, researchers mapped GLP-1 expressio

This past weekend in Melbourne was a special one. F1 was in town, and for those who know me well the Melbourne Grand Prix weekend has quietly become a bit of a tradition. Part of the time is spent at the track with my son and a few of his friends, soaking up the atmosphere, the speed, and the remarkable engineering that makes F1 such a fascinating sport. The rest of the weekend usually unfolds in a slightly different way. A few close friends gather around the TV coverage and

Most leaders I work with assume that healthier choices require more education, more motivation, or more discipline. But the science of behaviour change says something far simpler… and far more powerful. A large field study at Google by Baskin et al., 2016 - https://www.sciencedirect.com/science/article/abs/pii/S0195666316301465  examined what happened when snacks were positioned closer to, or further from, beverage stations in a workplace kitchen. No lectures. No calorie labe

Most senior leaders I work with don’t struggle with capability. They struggle with chronic activation. Always on. Always reachable. Always scanning for the next problem. And biologically… that takes its toll. When stress becomes persistent, the body shifts from adaptive response to allostatic load. Cortisol and catecholamines remain elevated, heart rate variability drops, inflammatory pathways increase, and recovery systems are suppressed (McEwen, 2017 - https://pubmed.ncbi.n

For years, organisations have invested in resilience workshops, mindfulness apps, stress management classes and EAPs. Some of these are helpful, many are well-intentioned…but a fundamental question often goes unasked: “What if the single biggest driver of organisational performance isn’t the programs we offer employees…but the wellbeing of the people leading our employees?”   A major study, the 2025 WorkWell Leaders Impact Measure , analysed over 200 factors influencing organ

Most people don’t struggle because they lack capability, they struggle because they’re mentally saturated. 📅 Back-to-back meetings, 🤯 Constant decisions, 🚨Very little space to think. And then, almost without noticing, something shifts over the holidays. for a lot of people - 🥾More walking. 🌞 More daylight. 🌱 More time outside. Thinking feels clearer. Perspective widens. Pressure softens. That’s not a coincidence... As many of us return to work for 2025, one of the bigge

AI is advancing at extraordinary speed. Tools are becoming faster, cheaper, and more capable by the month. And yet…many leaders I work with don’t feel more effective. • They feel cognitively overloaded  • More distracted  • More fatigued  • Less able to think clearly under pressure 

Yes, the new generation is extraordinary and yet… when you zoom out, it’s impossible not to pause at what Novak Djokovic  has achieved on the courts of Australian Open . Longevity. Consistency. Reinvention.  Not dominance through force… but through adaptation, recovery, and perspective 🧠🔄 Ageing doesn’t automatically equal decline.  What declines fastest is recovery capacity  if we stop protecting it. High-impact journals including The Lancet , Cell , Nature , and The Journ

I see it every week with senior leaders and executive teams. Smart people. High standards. Genuine intent. And yet health initiatives still don’t stick. Not because people don’t care…but because the system around them makes the healthy choice the hard  choice. Decades of behavioural science show that knowledge alone rarely drives sustained behaviour change. Health behaviours are shaped far more by environment, stress load, social norms and cognitive capacity than by willpower

Here’s the quiet pattern I see in senior leaders under sustained pressure…decision quality drops long before motivation does. Not because people don’t care, but because their nervous system is overloaded. 🧠Our brains have a limited capacity for self-regulation and decision-making across the day. ❌Prolonged cognitive demand increases mental fatigue, reducing accuracy, impulse control, and judgement ❌This effect is linked to changes in prefrontal cortex activity and rising str

Most leaders I work with assume that if the science is strong enough, the outcomes should follow. Powerful intervention in… better results out. But the evidence suggests it’s not that simple. A large real-world study published in JMIR  followed over 126,000 adults with obesity  who were prescribed tirzepatide and enrolled in a digital weight-loss service ( J Med Internet Res, 2026 ). What the researchers explored wasn’t a new drug mechanism… but something far more human: enga

They’re driven.They care.They’re committed. But they’re trying to lead complex systems on a partially charged brain 🔋 Here’s the part we often miss… 🧠 The science is very clear Sleep isn’t passive rest.It ’s an active biological process that restores the very systems leaders rely on most. Peer-reviewed research consistently shows that insufficient sleep is associated with: ❌ Reduced prefrontal cortex activity, impairing judgement and impulse control (Killgore, 2010 -...
