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  

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

Most leaders I work with believe recovery only happens when the diary is empty. No meetings. No emails. No noise. But this week, walking through a snow-covered Paris, the lesson felt different. Recovery isn’t the absence of life…it’s the presence of the right inputs.
