The Ten Essentials of a Healthy Leader

Our world is built by leaders. Women leaders, increasingly, are the ones building it — and it is clear from twenty years of practice that many of the rules written for the previous generation do not survive contact with the current one. What follows is a field manual — ten essentials distilled from clinical practice, the peer-reviewed literature, and the quiet conversations that happen at the end of a conference day, when the microphone is off.

1 · Be well

The path to leadership is often paved with sleepless nights, last-minute deadlines and the exercise of the prefrontal cortex. With the right mix of dedication, hard work and perseverance, anyone can reach the room. But the capacity to operate effectively once inside it is entirely contingent on the body that arrived there. Without health, leadership is unsustainable. This is not moral; it is mechanical.

Obesity, diabetes, hypertension and the other lifestyle-driven illnesses dull the mind. Wellness is not a gym membership and an occasional salad. It is an active state — the capacity for optimal physical, emotional and psychological functioning. It includes health maintenance, screening, allopathic and integrative medicine, stress management, nutrition and movement. The fitter the leader, the larger the reserves available to meet what the day brings.

2 · Lead by example

When thought leaders build a deeply ingrained wellness culture, employees adopt it. The Journal of Occupational and Organizational Psychology is clear: an employee’s perception of the workplace shapes long-term health and adjustment. Three management behaviors correlate consistently with better employee health: giving employees real control over how they reach their goals, praising in public and correcting in private, and acting — not just talking — in the direction of the culture you wish to create.

When the best leader’s work is done, the people say: we did it ourselves. — Lao Tzu

One large study rated 3,000 managers on delegation, communication, feedback and responsibility. Employees of highly rated managers were significantly less likely to die of cardiovascular disease and stroke than employees of the opposite. Your leadership is not only a career question. It is a public-health variable.

3 · Well-Thinking

Executives deal in continuous pressure: multiple priorities, endless demand, conflicting deadlines. Well-Thinking is a deliberate practice of restoring order, balance and control — an open, agile, relaxed state of mind built through mindfulness, acceptance, reappraisal, attention regulation, flexibility, emotion regulation and the conscious rewiring of cognitive distortions. Meditation is a method. Mindfulness is its state: moment-to-moment awareness of what you are experiencing while you experience it.

Leaders with organized minds keep their attention where they put it, even under pressure. Most of us do not come by this naturally. All of us can build it.

4 · Sleep is strategy

Sleep is not a luxury. When the decisions on the table are consequential, a good night of sleep contributes more to getting them right than almost anything on your to-do list. Your prefrontal cortex — the seat of working memory — requires it. Sleep lowers stress hormones. It consolidates learning. Animal and human studies now converge: both the quantity and the quality of sleep shape memory, judgment and emotional regulation.

Learning happens in three movements. Acquisition (taking in the information — awake). Consolidation (making it stable — during sleep, especially deep sleep). Recall (retrieving it later). Shortchange consolidation and you are left with impressions instead of knowledge.

Short naps are permitted. Twenty minutes resets alertness and motor control. Thirty to sixty minutes sharpens decision-making. Sixty to ninety minutes allows REM — the phase in which new neural connections form and problems quietly solve themselves.

5 · Personal health risk management

Embracing risk can be a competitive advantage. Risk management is about lessening the impact of what you do not yet understand. The same disciplines that protect an enterprise can protect a body. Understand your genetic predispositions, your lifestyle factors, and the environment you operate in. Use DNA testing, blood work and probabilistic tools to make the invisible visible.

Few health problems are entirely genetic or entirely behavioral. Most are the result of a complex interplay. The right lifestyle decisions are, for most of us, a non-pharmaceutical prescription — one that transforms everyday thinking and everyday practice into durable outcomes.

The most important questions of life are, for the most part, really only problems of probability. — Pierre-Simon Laplace

6 · Food as fuel

Calories are the fuel of human life. The adage is correct — you are what you eat, incorporated atom by atom into the body doing the eating. Think of the body as a vehicle. It needs fuel and oxygen to run. Starve it, or fill it with the wrong fuel, and it will not simply stop. More often it will sputter through a long, painful, preventable decline.

If you maintain an active life, you will burn more calories than someone sedentary. Everyone idles, however, and the idle rate — breathing, circulation, digestion, repair, thinking — cannot be switched off. The only real levers are input, activity and recovery.

Michael Pollan’s counsel is tidy enough to live by: don’t eat anything your great-great grandmother wouldn’t recognize as food.

7 · Moderation management

Not every problem drinker is an alcoholic. At least seventy-five percent of people who drink above healthful levels are not. Moderation Management is a behavioral-change program built on the evidence that, for many non-alcoholic problem drinkers, moderation — not abstinence — is the achievable and appropriate goal. Early self-recognition of risky drinking behavior is more effective, less costly and more sustainable than waiting for dependency to set in.

The research on moderate drinking, especially cardiovascular, is meaningful — the risk of dying in a given year is roughly 25% lower for moderate drinkers than for abstainers; morbidity and mortality from coronary heart disease are 40–60% lower; diabetes risk in moderate drinkers is roughly 30–40% lower. Heavy drinking is associated with the opposite. The line matters.

8 · Exercise is medicine

Physical inactivity causes roughly ten percent of all premature deaths worldwide, primarily through cardiovascular disease, Type 2 diabetes, and breast and colon cancers. Regular physical activity — thirty minutes most days — reduces the risk of recurrent breast cancer by about half, lowers colon-cancer risk by about sixty percent, reduces Alzheimer’s risk by roughly forty percent, and reduces the incidence of hypertension, heart disease and diabetes by thirty to fifty percent.

There is almost no chronic condition that is not improved by regular exercise. Arthritis, obesity, anxiety, depression — all respond. Exercise is not the metaphor of medicine. It is medicine.

9 · Know the dangers of stress

Stress is inevitable. The healthy leader lives in a way that converts potentially harmful reactions into healthy responses to the inevitable demands of success. Symptoms — pounding headaches, queasy stomachs, tight chests, anxiety — are warnings, not identities. Untreated, chronic stress increases the risk of depression, diabetes, heart disease, obesity, dementia and stroke.

Leaders are not exempt. But the research is surprisingly hopeful. In one study published in the Proceedings of the National Academy of Sciences, leaders had lower cortisol than their direct reports — a lower stress response that was explained by a single variable: the sense of control. Air-traffic controllers with long careers showed lower stress hormones than the ones who quit early; the latter had elevated cortisol even before starting their shift.

In the corporate world, it is not C-levels who experience the highest stress. It is the middle managers — high demand, low control.

When leaders feel rudderless, they succumb. Over time, chronic stress and a lack of control feed each other. The exit is taking meaningful control of the things that are controllable, reframing what is not, and building the practices that keep you inside — rather than outside — your best stress zone.

10 · Discover your BestStressZone®

Grounded in the principles of demand-control theory, neuroplasticity and lifestyle medicine, the BestStressZone is both a state and a strategy. It is a place to view, organize and shape your world that enables resilience and healthy responses to the challenges of a leading life.

In the zone, you do not merely measure your stress. You regulate it. You act as a thermostat, not a thermometer. Your daily actions align — mostly unconsciously — with your life purpose, your passions and your priorities. You know the warning signs that are unique to you. Lack of creativity. Irritability. Procrastination. A grinding jaw. You adjust before the damage compounds.

This is the work.
