What if your sleep tracking, glucose levels, and wearable health devices weren't just numbers, but signals your body is trying to send you? Live from the Biohackers World Conference, functional nutritionist and author Danielle Pashko discusses with David Korsunsky, founder of Heads Up Health, how health data analytics can become a powerful tool for real behavior change, not obsession. David shares how his own struggle with poor sleep led him to biofeedback devices, health tracking apps, and eventually building one of the most widely used personalized health platforms for clinics today. Together, they explore how sleep optimization, blood sugar monitoring, wearables, labs, and even mindset show up in measurable biomarkers and how to use that information wisely. You'll learn: • Why sleep quality tracking was the first domino in David's health transformation • How biofeedback training changes behavior faster than motivation alone • When health data monitoring helps, and when it can actually backfire • Why clinicians matter more than apps when interpreting health metrics analysis • How emotional and psycho-spiritual health often shows up in your quantified self data • What AI health tracking and smart wearables mean for the future of personalized medicine. This episode is a must-listen for anyone using fitness trackers, CGM devices, or lab tests, and wondering how to turn all that biometric data into calmer, smarter daily decisions through data-driven health optimization and self-quantification strategies.
