More than how long you sleep

Sleep is one of the most powerful pillars of longevity, performance, hormonal balance and overall wellbeing. My approach goes beyond hours in bed. It’s about understanding how your body recovers, adapts to stress and regenerates.

Alongside the data, I look at your habits, stress load, energy, nutrition, environment and daily routine. Together, these show what is really affecting your sleep, recovery, focus, mood and biological ageing.

Every protocol is tailored to you, built from scientific data, biofeedback and evidence-based longevity strategies. The result is a sustainable system that helps you sleep deeper, recover faster and manage stress better.

What I track

Using advanced wearables and biometric tracking. HRV is at the centre of my work: it shows how balanced your nervous system is and how well you recover.

  • Heart rate variability (HRV)
  • Resting heart rate
  • Sleep stages and recovery patterns
  • Circadian rhythm alignment
  • Nervous system regulation

Deeper testing, when needed

To build a complete health profile and uncover hidden imbalances, I can arrange functional tests through accredited laboratories.

  • Microbiome analysis
  • Hormonal testing
  • DNA and genetic insights
  • Inflammation markers
  • Other longevity-focused assessments

The goal isn’t only better sleep. It’s a body that recovers well, so you have more energy, clearer thinking and better long-term health.

Rental sleep trackers

Track your sleep. Elevate your potential.

Borrow a professional wearable and sleep at home as normal. It records your HRV, recovery, stress and sleep stages each night, so we can see how your body really recovers and adjust your plan from real data.
