For Medical Groups • Hospital Systems • High-Performance Organizations

Your team cannot perform at their best
if their nervous systems haven’t been prepared.

PRE►LOΔD is a 90-day neurobiological preparation program grounded in Karl Friston’s predictive processing framework, validated clinical instruments, and HRV biofeedback. Built by a practicing cardiothoracic anesthesiologist.

The Problem

High-performance environments demand regulated nervous systems.
Most training programs don’t address this.

Surgical teams, executives, first responders, and high-stakes professionals are trained in technical skills. Almost none receive training in the neurobiological preparation that determines whether those skills deploy correctly under pressure.

🧠

Predictive Processing

PRE►LOΔD trains the brain’s prediction systems before high-stakes moments arrive — not after the stress response has already fired.

💓

HRV as Daily Readiness

Heart Rate Variability is the most sensitive daily measure of nervous system state. The program treats it as a morning dashboard, not an afterthought.

📊

Outcome Measurement

GAD-7, PHQ-9, PSS-10, and PERMA assessments built in. Your organization can track measurable changes in anxiety, reactivity, and performance over time.

💞

Family & Relationship Layer

Performance doesn’t stop at the hospital door. The program explicitly addresses how nervous system state affects the people who matter most.

🌱

The 90-Day Program + Lifetime Practice

A defined 90-day arc with a clear completion milestone, followed by adaptive maintenance mode for ongoing practitioners. Ninety days is the container, not a deadline.

✅

Faith & Values Integration

Optional multi-faith spiritual layer including LDS, Christian, Buddhist, Jewish, Islamic, Stoic, and secular frameworks. The program meets each person where they are.

The Framework

The Whole Person Architecture

“And Jesus increased in wisdom and stature, and in favour with God and man” (Luke 2:52). Four dimensions, growing together. Spiritual is the center; physical, intellectual, and social overlap it and one another.

✦

Spiritual — favour with God

Your deepest predictions: who you are, what your life is for, whether you are known and loved by something larger than your circumstances. The center.

●

Physical — stature

Not merely the vehicle for the mind but the raw data stream from which every emotion and prediction is built.

◉

Intellectual — wisdom

The mind that learns — which, at the level of the brain, simply means updating old predictions with better ones.

◎

Social — favour with man

The relationships through which your sense of “normal” is downloaded, and through which your own state is broadcast to everyone near you.

The Evidence Base

Not wellness content.
Applied neuroscience.

Every tool in PRE►LOΔD maps to a specific mechanism in the literature. The program draws on Friston, Sapolsky, Porges, Lally, Oettingen, and a curated set of landmark studies on stress, habit, and performance.

5.5s

Inhale five and a half seconds, exhale five and a half — about six breaths a minute, the resonance pace near 0.1 Hz. Done for a few minutes, the fastest reliable way to nudge the autonomic system toward order (Lehrer & Gevirtz, 2014)

WOOP

Oettingen’s mental contrasting is, by effect size, among the most reliable interventions in all of behavioral science — and the obstacle is the active ingredient (Oettingen, 2014)

90s

In the ninety seconds before a hard moment, shifting the goal from protect myself to contribute something measurably lowered stress-hormone response (Abelson et al., 2014)

3wk–8mo

How long a behavior takes to become automatic — about two months on average, but ranging from roughly three weeks to eight months. We do not hand you a magic number of days. We hand you a gate: automaticity, not the calendar (Lally et al., 2010)

“You are not the problem. Your preparation is.”
— PRE►LOΔD, “About This Book”

Christopher D. D. Larson, D.O. is a practicing cardiothoracic anesthesiologist who spent years in one of medicine’s highest-stakes environments before realizing that the critical variable wasn’t skill — it was the state of the nervous system that deployed those skills.

PRE►LOΔD is the program he built from the ground up, drawing on Karl Friston’s predictive processing framework, validated clinical instruments, and his own experience as a husband, father, and physician navigating high-stakes moments daily.

The book PRE►LOΔD: Prepare Your Neurobiology Before the Moment Arrives is the work this program is built on. The app at preload.life is its companion — in the author’s words, “a convenience, never a requirement.”
