Rewiring stress: health and wellness strategies for high-performing leaders

Executive overview

High-achieving leaders often mistake chronic stress for a necessary feature of success — until the body breaks down. Zahra Karsan, mindset coach and neuroscientist, nearly burned out after 20 years as a management consultant before discovering that inner calm and high performance are not opposites.

Her framework, distilled into the book Six Weeks to Happy, draws on positive psychology and neuroscience to rewire the brain and nervous system back to balance. It addresses five universal subconscious belief patterns — including imposter syndrome and the "I'm alone" story — that silently drive burnout, communication breakdowns, and leadership dysfunction.

The core insight: a calmer nervous system doesn't dull your edge — it's the prerequisite for creativity, strategic thinking, and sustainable performance.

The burnout trap and what causes it

• Treating high stress as a permanent operating mode leads to adrenal fatigue and eventual collapse.
• Many leaders run at two speeds only: Olympic-on or offline — with no recovery in between.
• The body's stress response was not designed to run continuously; chronic activation depletes rather than sharpens performance.
• Zahra's turning point: realising she did everything — walked, breathed, spoke — at full speed, all the time.
• The formula for external success (career, money, house) does not automatically produce wellbeing.

How you start the day shapes the whole day

• Beginning the day with a news barrage throws the nervous system into fight-or-flight from the first minute.
• Starting drained means never reaching full capacity — the day begins in deficit.
• A quieter, more intentional start allows the nervous system to return to its natural rest-and-digest baseline.
• Practical alternatives: waking to natural sounds, reading selectively, visualising priorities before opening devices.
• Time-box news consumption; do not let it be the first or last thing you consume.
• Leaders who send demands at all hours impose their stress response on their entire team — often without awareness.
• Coaching fix: change notification settings so others can centre themselves before encountering high-urgency messages.

Why relaxed employees are more productive

• Innovation and creativity draw on different neural pathways than task-based work — pathways that only activate in a calmer state.
• The "eureka in the bath" effect is neurologically real: solutions emerge when the brain shifts away from focused effort.
• Strategic thinking uses the same brain processes as creative work — both require mental spaciousness.
• A major bank Zahra worked with found ~40% of its workforce pre-diabetic and 80% reporting moderate-to-high stress.
• Absenteeism and stress leave were measurable productivity losses, not just HR concerns.
• Fitness challenges with weigh-ins backfired; employees felt bullied rather than supported.
• Effective wellness programs teach people how their body processes food, manages energy, and avoids the afternoon energy crash — giving tools, not mandates.

Movement and meeting design

• Sedentary work is not a neutral baseline — the body was not built to sit for eight hours.
• Standing meetings cut session length without cutting quality; brevity becomes the default.
• Walking to a colleague's desk instead of calling adds micro-movement that accumulates across the day.
• Standing desks measurably improved focus and energy for one participant recovering from a back injury.
• The daily huddle format — standing, time-boxed, one minute per person — is as effective as longer meetings and more action-oriented.

The five subconscious belief patterns

Every person operates from one or more of these core beliefs, which play out in both personal and professional behaviour:

1. I'm not good enough — manifests as imposter syndrome; can drive overwork and perfectionism.
2. I'm alone in this world — sounds like "if I want it done right, I have to do it myself"; common in founders and firstborns.
3. I'm not safe — drives hypervigilance and risk-aversion.
4. I'm not worthy of love — affects how people accept support, feedback, or recognition.
5. I'm not worthy of wealth and abundance — limits financial confidence and delegation.

Imposter syndrome: it doesn't go away

• Imposter syndrome is not a one-time passage — it resurfaces across contexts throughout a career.
• The subconscious evolved to keep us safe, not to run our thoughts and behaviours at scale.
• Awareness is the only real tool: you bring the belief into consciousness so it no longer operates unchecked.
• The goal is not elimination but learning to use the underlying strength (e.g., self-sufficiency) without letting the fear dominate.
• Leaders with the "I'm alone" belief often became leaders precisely because they are comfortable operating independently — it is both a strength and a liability.

Reframing self-talk and the language of mantras

• Negative framing ("I am not alone") is less effective than a positive reframe ("I am fully supported").
• The subconscious negates the word "not" — it hears the noun that follows, not the negation.
• Positive reframes ("I am fully connected," "I am part of something larger") calm the nervous system directly.
• The LifeBlock quiz maps personality to animal archetypes representing subconscious belief patterns, making them visible and workable.
• Bringing an unconscious belief into awareness — not suppressing it — is what allows leaders to develop it in a healthy direction.

The CEO communication gap

• A CEO with imposter syndrome struggled to articulate his vision, leaving his team to interpret it without guidance.
• The solution: present multiple recommendations rather than naming the gap directly — the CEO chooses and the choice becomes their insight.
• This approach preserves the leader's authority while closing the real problem (lack of a communication plan).
• Even senior leaders carry the same five basic fears as everyone else; the rank does not dissolve the human condition.

Work culture and the European contrast

• A Dutch consulting firm asked Zahra about her hobbies in an interview — to assess whether she had work-life balance, not as small talk.
• Dutch employees worked 7.5-hour days and were at least as productive as North American counterparts working 10–12 hours.
• Being rested means showing up at full capacity from the start — not waiting two hours for caffeine to offset exhaustion.
• Different cultures (Italian long lunches, Dutch brevity, German discipline around holidays) each offer a lens for reassessing default work habits.
• Scanning other cultures is a practical tool for challenging assumptions about what "normal" looks like.

The Christmas Eve mutiny

• Zahra kept her team working on Christmas Eve because she couldn't tolerate leaving tasks incomplete before the holiday.
• Looking back: everything could have waited.
• The lesson: not everything is urgent — using a traffic-light system (red, amber, green) makes real urgency visible and most tasks can be deprioritised.
• Leaders need to give themselves and their teams permission to stop.
