The Extended Human
The Extended Human
Not trends. Not opinions. Not wellness marketing. What the peer-reviewed science actually shows about human health, longevity, and wellbeing.
This research hub synthesises peer-reviewed evidence on the biological foundations of human health. Rather than offering prescriptions, we document what the published science demonstrates about fundamental health behaviours, their physiological mechanisms, and their consistency (or lack thereof) across populations.
We name the researchers. We cite the studies. We distinguish between single experiments, meta-analyses, and consensus in the literature. This is educational content based on published evidence, not medical advice. The goal is clarity: to see what the science actually shows, not what marketing claims it shows.
Each topic explores the latest evidence on how specific behaviours affect human physiology at the cellular, systemic, and organismal level. The frontier of human health is not found in supplements or hacks. It is found in understanding what your biology requires.
The most powerful health intervention available—and the one most consistently neglected. What happens in your brain during sleep, why it matters for every system in your body, and what the evidence actually shows about duration, consistency, and light exposure.
Read the Research →A synthesis of metabolic research on how different food groups affect glucose homeostasis, lipid profiles, inflammatory markers, and long-term disease risk. Not a diet guide. What the evidence shows about macronutrients, micronutrients, and whole foods.
Read the Research →How physical activity alters cardiovascular physiology, muscle protein synthesis, mitochondrial density, and neurogenesis. What intensity matters. What frequency matters. What the data shows about sedentariness as a risk factor for disease.
Read the Research →How the ancient stress response system responds to modern threats, the physiology of chronic activation, and what the research shows about regulatory techniques for bringing the nervous system back to baseline.
The trillions of bacteria in your gut and their role in immune function, metabolism, barrier integrity, and even mental health. What the evidence shows about dietary influences on microbial composition and its consequences for health.
How caloric restriction and time windows affect metabolic switching, autophagy, circadian alignment, and longevity pathways. What the evidence shows about duration, frequency, and individual variation in response.
