Glossary

Atlas Cove's operating system for your health: a living profile that connects intake, profiling, protocol design, and continuity into a single integrated system. Built to track strength, endurance, sleep, recovery, metabolic health, and resilience, and to evolve with every visit. The full digital profile is in active development; at our pilot retreats, Atlas Capacity runs as a focused physical baseline plus non-invasive check-ins.

The branch of the nervous system controlling involuntary functions: heart rate, digestion, respiratory rate, and stress response. Divided into sympathetic (fight-or-flight) and parasympathetic (rest-and-digest). Balance between the two, measured via HRV, is a key health indicator.

A cellular recycling process where damaged proteins and organelles are broken down and reused. Upregulated by fasting, exercise, and sleep. Plays a critical role in cellular health, immune function, and protection against neurodegeneration.

The six interconnected pillars that form the foundation of lasting health at Atlas Cove: Sleep & Recovery, Physical Activity, Nutrition, Mental Energy & Health, Social & Community, and Biomechanics.

An estimate of how old your body is based on biomarkers rather than calendar years. Measured through epigenetic clocks (DNA methylation), telomere length, and functional capacity tests. Can diverge significantly from chronological age.

Measurable indicators of biological health such as blood glucose, cortisol, VO2max, HRV, body composition, and inflammatory markers. Comprehensive multi-biomarker tracking is part of the Atlas Capacity roadmap; our 2026 pilot retreats capture a focused physical baseline.

Geographic regions identified by researcher Dan Buettner where people live significantly longer than average. Includes Okinawa (Japan), Sardinia (Italy), Nicoya (Costa Rica), Ikaria (Greece), and Loma Linda (California). Common traits: plant-based diet, daily movement, strong community, and sense of purpose.

The body's internal 24-hour clock that regulates sleep-wake cycles, hormone release, body temperature, and metabolism. Disruption (from shift work, jet lag, or blue light exposure) is linked to metabolic disease, mood disorders, and impaired recovery.

The intended year-round layer that keeps your health gains between residential stays, planned to include remote coaching, app-based tracking, and community access. In development; our 2026 pilot retreats focus on the residential experience and baseline.

The primary stress hormone produced by the adrenal glands. Follows a natural diurnal rhythm (high in the morning, low at night). Chronic elevation disrupts sleep, metabolism, immune function, and recovery. Atlas Cove protocols target cortisol rhythm restoration.

The stretch of Portuguese coast in the Setúbal District, south of Lisbon, framed by the cliffs of Serra da Arrábida natural park. Known for clean Atlantic air, a mild year-round climate, pine forest, and quiet beaches. Atlas Cove's 2026 pilot retreats are held here, at Casas na Ferraria in Sesimbra.

Dual-Energy X-ray Absorptiometry. A precise body composition measurement that differentiates bone mineral density, lean mass, and fat mass by region. Considered the gold standard for body composition analysis.

The study of changes in gene expression that do not involve alterations to the DNA sequence itself. Environmental factors like nutrition, exercise, sleep, and stress can modify epigenetic markers, influencing disease risk and ageing rate.

Movement patterns that reflect real-world activities: squatting, lunging, pushing, pulling, rotating, and carrying. Functional movement screening identifies imbalances and injury risk. Programming addresses deficits before adding load or intensity.

The degree of fluctuation in blood glucose levels over time. High variability, even in non-diabetic individuals, is associated with increased cardiovascular risk, impaired cognitive function, and accelerated ageing. Monitored with continuous glucose monitors (CGMs).

Maximal force applied by hand grip, measured with a dynamometer. One of the most reliable and accessible predictors of overall mortality, frailty, and functional capacity in ageing populations. Correlated with total body muscle mass and neuromuscular function.

The assessment conducted at the start of a residency stay to establish your baseline. At our 2026 pilot retreats, this is a focused physical baseline plus non-invasive check-ins, lifestyle factors, and health history. The full multi-biomarker intake is part of the Atlas Capacity roadmap.

The practice of actively improving health markers beyond the absence of disease. Focuses on building physical capacity, metabolic efficiency, cognitive performance, and stress resilience to their highest sustainable levels.

A personalised, evidence-based program designed around your Atlas Capacity. Covers movement, nutrition, recovery, and mindset, and is adjusted as your data evolves.

A structured, multi-night residential stay designed to build measurable health capacity. Unlike a retreat or spa, a residency follows a structured protocol with a clear baseline and outcomes. Atlas Cove's 2026 pilot retreats run as five-night and seven-night residencies.

The number of years lived in good health, free from chronic disease and disability. Distinct from lifespan (total years alive). Extending healthspan, not just lifespan, is the core mission of Atlas Cove and the longevity field.

A biological principle where a mild stressor (cold exposure, fasting, high-intensity exercise) triggers adaptive responses that make the organism stronger. The foundation of many longevity interventions including cold water immersion, sauna, and intermittent fasting.

The variation in time intervals between consecutive heartbeats, measured in milliseconds. Higher HRV generally indicates better autonomic nervous system balance, cardiovascular fitness, and stress resilience. Tracked continuously in the Atlas Capacity using RMSSD and SDNN metrics.

Low-grade, persistent inflammatory response that drives most chronic diseases including cardiovascular disease, diabetes, neurodegeneration, and cancer. Measured through markers like hs-CRP, IL-6, and TNF-alpha. Distinguished from acute inflammation, which is a healthy immune response.

How effectively cells respond to insulin to take up glucose from the bloodstream. High insulin sensitivity is a marker of good metabolic health. Impaired sensitivity (insulin resistance) precedes type 2 diabetes and is linked to inflammation, obesity, and cardiovascular disease.

The science and practice of extending both lifespan and healthspan. Modern longevity medicine focuses on identifying and mitigating the root drivers of ageing: metabolic dysfunction, chronic inflammation, loss of muscle mass, cognitive decline, and social isolation.

A dietary pattern emphasising whole grains, vegetables, fruits, legumes, nuts, olive oil, and fish, with moderate wine and minimal processed food. Consistently associated with reduced cardiovascular disease, improved cognitive function, and increased longevity in large-scale studies.

The body's ability to efficiently switch between oxidising carbohydrates and fats for fuel depending on availability and demand. A hallmark of metabolic health, impaired in insulin resistance and type 2 diabetes.

The trillions of bacteria, fungi, and other microorganisms living in the gut and throughout the body. Influences digestion, immune function, mood, and metabolic health. Diversity and balance of the microbiome are markers of overall health.

Organelles within cells responsible for producing ATP (cellular energy). Mitochondrial density and function decline with age and sedentary lifestyle. Zone 2 training, cold exposure, and certain nutritional strategies support mitochondrial biogenesis.

An approach to health that tailors interventions to the individual based on their unique biology, genetics, lifestyle, goals, and data. Contrasts with one-size-fits-all public health guidelines. Enabled by biomarker tracking and adaptive protocols.

Medical practice focused on disease prevention rather than treatment. Includes primary prevention (avoiding disease onset), secondary prevention (early detection), and tertiary prevention (minimising impact). Atlas Cove focuses primarily on primary and secondary prevention.

Building health before disease occurs, as opposed to treating illness after the fact. Includes lifestyle interventions, regular screening, and proactive health management. Atlas Cove's entire model is built around primary prevention infrastructure.

The component of Atlas Capacity, in active development, that will generate personalised programming across movement, nutrition, recovery, and mindset from your profile. At our 2026 pilot retreats, programming is designed by our facilitators around each guest's baseline.

The physiological process of adaptation following exercise or stress. Encompasses sleep, nutrition, parasympathetic activation, and tissue repair. Without adequate recovery, training stimulus becomes stress accumulation rather than fitness gain.

The structure of sleep across a night, comprising cycles of light sleep (N1, N2), deep sleep (N3/slow-wave), and REM sleep. Each stage serves distinct functions: deep sleep for physical recovery and growth hormone release, REM for memory consolidation and emotional processing.

Protective caps at the ends of chromosomes that shorten with each cell division. Telomere length is considered a biomarker of biological ageing. Chronic stress, poor sleep, and sedentary behaviour accelerate shortening, while exercise and healthy nutrition may slow it.

A form of intermittent fasting that limits food intake to a specific daily window (commonly 8-12 hours). Aligns eating with circadian rhythm, supports metabolic health, and may improve insulin sensitivity and autophagy without requiring caloric restriction.

The maximum rate of oxygen consumption during incremental exercise. Measured in mL/kg/min. One of the strongest predictors of all-cause mortality and cardiovascular health. Improving VO2max by even one metabolic equivalent (MET) is associated with a significant reduction in mortality risk.

Aerobic exercise performed at moderate intensity (typically 60-70% of max heart rate) where the body primarily uses fat oxidation for fuel. Builds mitochondrial density, improves metabolic flexibility, and forms the aerobic base for all other fitness domains.
