About

Beyond Human is the personal platform of Rebeca S. Barriuso: applied science for leaders who want precision, not platitudes.

The Story

Science and healthcare

I have always been drawn to what helps us flourish. First through science, then through business, and finally through conscious human experience.

I began my path in healthcare. I studied Nutrition and Pharmacy, worked in public and private hospitals, and contributed to clinical trials.

Global business and leadership

I completed an Executive MBA at one of the world’s leading international business schools and moved into leadership positions in global health-tech and life-sciences companies.

For more than two decades, I worked inside the engine rooms of healthcare and innovation: building, scaling, and pushing forward. From the boardroom to the airport. From the presentation to the pitch. From the deal to the deadline.

I led global teams, designed go-to-market strategies, relocated abroad, and opened international markets across Europe, the United States, and Latin America. I negotiated with C-suites, partnered with investors, and built commercial engines that moved millions.

The 2022 breaking point

In 2022, I reached my limit. A complete collapse of the body. The kind of identity crisis that does not care about your résumé. Everything I had built on the outside no longer matched how I felt on the inside.

Returning to science and the nervous system

So I decided to reconnect: with my breath, my biology, my nervous system, my boundaries, and my truth.

I returned to science, this time through the lens of human experience. I studied Neuroscience and Psychobiology, and I am completing my ICF coaching certification.

Why Beyond Human exists

I founded Beyond Human for people who want to do the same—not by stepping away from leadership, but by redefining what power truly looks and feels like.

The System

The Beyond Human Method

The Beyond Human Method is the proprietary methodology underpinning my work. It brings together four integrated pillars. The goal is sustainable leadership performance through the alignment of physiology, cognition, autonomic regulation, and strategic coherence.

1. Precision Physiology

Optimising the body as the foundation of mental performance. High performance does not begin in the mind. It begins in biology. This pillar works with the physiological systems that support a leader’s energy, resilience, and longevity.

It includes functional nutrition and chronobiology, including metabolic timing, micronutrients, and insulin sensitivity; deep sleep and the architecture of rest, including latency, REM/NREM phases, and nocturnal HRV; exercise as a regulator of the nervous system, including strength, VO2 max, mobility, and recovery; and longevity and performance biomarkers, including advanced testing, wearables, and functional interpretation.

2. Regulated Cognition

Training the mind to think precisely under pressure. A leader’s brain operates under extreme cognitive load. This pillar develops the capacity to decide clearly, even in complex environments.

It includes cognitive-load management and decision fatigue; decision-making models under uncertainty, including heuristics, biases, and Bayesian evaluation; attentional clarity through deep work, noise reduction, and focus architecture; and applied metacognition—thinking about how you think, including calibration and epistemic confidence.

3. Autonomic Regulation

Mastering your nervous system as a leadership tool. The autonomic nervous system is the invisible operating system that shapes how you respond to stress, threat, and uncertainty. Regulation is not the same as relaxation. It is the expansion of your window of tolerance.

It includes polyvagal theory applied to leadership, including ventral, sympathetic, and dorsal states; mapping vagal tone and HRV as indicators of regulation; intentional regulation practices, including breathing, exposure, and cardiac coherence; and somatic management of chronic stress and executive burnout.

4. Strategic Coherence

Aligning who you are with what you lead. Sustainable performance requires coherence between values, identity, vision, and action. This pillar integrates the other three into a personal strategic framework that connects biology with purpose.

It includes leadership-identity design—who you need to become versus who you are being; free-will architecture, distinguishing conscious decisions from automatic ones; psychosomatic integration, aligning body, emotion, thought, and action; and personal strategic vision, including legacy, impact, and direction over ten years.

Proprietary frameworks

These working models are Beyond Human intellectual property; they underpin selected protocols, programs, and 1:1 work.

Decision Density™

Optimising the volume and quality of decisions per unit of time and energy.

Free-Will Architecture™

Increasing the ratio of conscious choices to automatic reactive patterns.

The 8 Decision Edges™

Eight cognitive-emotional edges that shape executive decision quality.

Identity Threshold Theory

Understanding the identity shift required at each leadership transition.

Coherence OS™

Aligning biology as hardware, cognition as software and purpose as direction.

Beyond Human Longevity Score™

A composite view of physiological markers, cognition and sustainable performance capacity.

The Science

Scientific and academic foundation

My work is grounded in a background spanning clinical nutrition, pharmacy, clinical trials, health technology, life sciences, neuroscience, psychobiology, and executive leadership.

Clinical and research experience

My professional track record includes work as a dietitian-nutritionist in oncology, gynaecology, cardiology, and internal medicine in public and private hospitals. It includes clinical-trial work for Big Pharma focused on generating scientific evidence. I also led one of Spain’s first clinical nutrition practices.

My later leadership work has included digital therapeutics, medical imaging, global health technology, life sciences, and open innovation. I currently lead open innovation at Sanitas (BUPA).

Evidence, models, and professional boundaries

The Beyond Human Method is a proprietary methodology. Its named frameworks are working models and intellectual property; they should not be read as diagnoses, clinical treatments, or guarantees of outcomes.

The work combines applied science with leadership development and coaching. It does not replace medical, psychological, or psychiatric care. The available source material does not claim that every element of the Method has the same level of scientific evidence. Where a concept is presented as a proprietary framework, it is identified as such.

Beyond Human does not administer, prescribe, recommend, or facilitate the use of controlled substances. Integration coaching is professional coaching for processing and integrating personal experiences, not therapy or a substitute for care. Clients are responsible for their own decisions and should consult qualified medical professionals.
