Quantified Self Toolkit: Best Biohacking Devices in 2025

Remember when step counters were cutting-edge? Those days are long gone. Today’s self-tracking tools can measure everything from your sleep architecture to your cellular health. As biohacking becomes mainstream, the devices we use to track and improve our biology are evolving at warp speed. Let’s cut through the marketing noise and look at the tools…

Continuous Glucose Monitors for Non-Diabetics: Worth It?

Ever wondered what foods secretly send your blood sugar soaring? Or why you crash at 3 PM despite that “healthy” lunch? Continuous glucose monitors (CGMs) – once exclusive to diabetes management – are now trending in the wellness world. But at $100+ per month, are these sleek arm sensors worth it for people without diabetes?…

AI-Driven Personalization: The Rise of Digital Twins

Imagine having a virtual version of yourself – a mirror image that reacts to different foods, supplements, and workouts exactly like your real body would. This isnt sci-fi anymore. Digital twins are revolutionizing biohacking, allowing people to test interventions virtually before trying them in real life. The results? Faster progress, fewer setbacks, and truly personalized…

Building a DIY Home Lab: Ambient CO₂, VOC, and Light Sensors

Take a deep breath. What’s in that air you just inhaled? Most of us live in homes filled with invisible factors affecting our sleep, focus and overall health – but we can’t manage what we don’t measure. The solution? Your very own environmental monitoring system. With basic components and a weekend of tinkering, you can…

How to Interpret HRV: Norms, Training Readiness, Stress

Your watch says your HRV is 45ms. But what does that actually mean? Is it good? Bad? Should you work out today or rest? Heart rate variability (HRV) has become the go-to metric for athletes, biohackers and health enthusiasts looking to optimize their training and recovery. Unlike heart rate, which counts beats per minute, HRV…

Blood Oxygen, Respiratory Rate & COVID-Era Lessons

Remember when we all became amateur pulmonologists overnight? When pulse oximeters sold out everywhere and “happy hypoxia” entered our vocabulary?
