The 8 domains of longevity,
explained

No single number tells you how well you're aging. Not weight, not one blood marker, not how you feel on any given day. That's why the Aevum Protocol assessment — and longevity medicine more broadly — looks across multiple domains at once, rather than optimizing one in isolation.

Why domains, not just metrics

It's tempting to fixate on a single number — a cholesterol reading, a step count, a weight on the scale. But the body doesn't work in isolated systems. Poor sleep raises cortisol, which affects metabolic health, which affects cardiovascular risk, which affects cognitive function over time. A domain-based approach exists because these systems are genuinely connected, and a plan built around one number in isolation misses how the rest of your biology is actually behaving.

The 8 domains

1. 1
   Sleep & Recovery

   Not just how many hours you sleep, but sleep quality, timing, and how well your body recovers overnight — one of the highest-leverage domains in longevity medicine.

2. 2
   Nutrition

   Meal patterns, food quality, and how your diet approach supports (or works against) metabolic health and cellular repair.

3. 3
   Movement & Fitness

   Activity levels, strength training, and functional markers like grip strength — physical capacity is one of the strongest predictors of healthy aging.

4. 4
   Skin Longevity

   Skin is a real organ system, not just appearance — sun protection, skin concerns, and how your skin reflects broader biological aging.

5. 5
   Cognitive Health

   Mental sharpness, cognitive engagement, and the habits that build cognitive reserve for the decades ahead.

6. 6
   Cardiovascular & Metabolic Health

   Blood pressure, resting heart rate, and the metabolic markers that underlie much of chronic disease risk.

7. 7
   Stress & Mental Wellbeing

   Perceived stress, coping, and social connection — chronic stress is one of the most underestimated accelerators of biological aging.

8. 8
   Hormones & Reproductive Health

   Hormonal balance and reproductive health, closely tied to energy, mood, metabolism, and long-term wellbeing.

Why they're assessed together

Two people can score similarly overall while needing completely different plans — one might need to prioritise sleep and stress, another movement and cardiovascular health. Assessing all 8 domains at once, rather than one at a time, is what makes it possible to see which 2 or 3 actually deserve priority for you specifically, instead of guessing or working on all of them equally.

This is exactly what the Aevum Protocol assessment is built to do — a single 40-question form covering all 8 domains, generating a personalised report that shows you where you actually stand, before any clinician gets involved.
