This case study shows how an 8-week nervous system capacity protocol helped a VP of Engineering recover executive cognitive capacity and focus.

Boosting Executive Cognitive Capacity: Reclaiming Focus

Getting the Executive Cognitive Capacity Nervous System Back Online

A VP of Engineering in Berlin increased his sustained focused-work minutes from 95 to 220 per day in just eight weeks by recalibrating his nervous system capacity. His resting HRV also shot up, from a rather dismal 28ms to a respectable 51ms. Most people would have called this burnout. It wasn't: it was a system running on fumes, constantly in a defensive crouch, and simply out of capacity to handle the load.

The presenting state

Most people, bless their cotton socks, would have seen the 3 PM cognitive crash and the decision fatigue as simply 'too much work' or 'not enough sleep'. But it goes deeper than that. This wasn't merely a lack of sleep; it was a nervous system locked in a high-alert state, making sound decision-making a Herculean task. His sympathetic nervous system was essentially running a continuous background process, draining resources faster than he could replenish them. The body, in its wisdom, prioritises immediate survival over strategic thinking when it perceives a threat, even if that threat is just another back-to-back meeting.

His HRV, a decent proxy for vagal tone and consequently, the flexibility of his autonomic nervous system, was flatlining. A resting Root Mean Square of Successive Differences (RMSSD) of 28ms is indicative of limited adaptive capacity, meaning his system struggled to shift states effectively Shaffer & Ginsberg, 2017. Sleep latency, at over 40 minutes, meant his brain literally couldn't switch off the 'on' button even when he was trying to rest. This wasn't just poor sleep hygiene; it was a physiological inability to downshift from the constant internal chatter of predictive interoception trying to manage an unpredictable environment Barrett, 2017.

The protocol

The goal wasn't to 'manage stress' — an utterly pointless endeavour — but to fundamentally expand his nervous system's capacity, enhancing its ability to flexibly respond to demands rather than remaining in a state of chronic activation. We focused on recalibrating his 'set point', helping his system learn to return to a more parasympathetically dominant state more easily, particularly between stressful events. The aim was to increase his interoceptive accuracy, the ability to accurately sense internal bodily states, allowing for earlier recognition and mitigation of escalating allostatic load Khalsa et al., 2018.

  • 5-minute down-regulation breathwork between meetings
  • Interoceptive recalibration practices (body scans during non-work tasks)
  • Breath-paced ventral cues (specific exhalation patterns to promote relaxation)
  • Structured evening shutdown ritual (no screens, specific wind-down activities)
  • Strength training (3x/week)
  • Zone 2 cardio (2x/week)
  • Magnesium glycinate supplementation (400mg before bed)

What changed

The most striking change, beyond the numbers, was the newfound ability to 'switch off'. The persistent mental hum that had plagued him for years began to dissipate. His focused work blocks became genuinely focused, not just periods of slogging through. The dip in the afternoon didn't disappear entirely — that's just part of being human — but it became a gentle slope rather than a cliff edge he'd regularly tumble over. The decision fatigue, once a daily antagonist, became a less frequent, less debilitating guest.

One rather fascinating detail I noticed in his biometrics was a significant increase not just in RMSSD, but specifically in the high-frequency band of his HRV during sleep, suggesting a much deeper, more restorative parasympathetic response. It wasn't just that he was getting more sleep; the quality of that sleep was profoundly improved. His system was finally optimising for recovery during rest, rather than just surviving it. This neurobiological shift meant less allostatic load during the day and improved cognitive function across the board McEwen, 2004.

We didn't solve his job; we just made his nervous system actually fit for it.

TL;DR

A VP of Engineering in Berlin, suffering from decision fatigue and cognitive crashes, significantly improved his executive cognitive capacity and resilience. Through an 8-week nervous system capacity protocol, including targeted breathwork, interoceptive exercises, and lifestyle adjustments, he nearly doubled his sustained focused-work minutes and significantly enhanced his resting HRV, demonstrating his system's improved ability to manage pressure.

Where to take this next

This case highlights that managing the demands of high-pressure roles isn't about working harder, but smarter, by first optimising the biological hardware. While this specific VP did brilliantly, the framework isn't exclusive. Anyone feeling that constant hum of being 'on' could benefit from tuning into their own internal signals.

True capacity isn't about avoiding stress; it's about building a system robust enough to navigate it efficiently. If this sounds like you, there's absolutely something we can do to dial down the internal noise and dial up your executive function and overall resilience.
