HRV is often reduced to a single number—usually RMSSD. But that number alone can’t explain how the autonomic nervous system is actually regulating the heart. This article walks through time-domain, nonlinear, and frequency-domain HRV metrics to show the difference between how much variability exists and how that variability is structured.
This post is a practical demonstration of exploratory data analysis (EDA) in action. Using a large diabetes dataset, I focus on how to interrogate feature distributions, assess overlap and separation, evaluate interactions, and translate visual patterns into testable modeling hypotheses. The emphasis is on how to think with data before building models—not on model performance…
Ever wonder how your smartwatch turns heartbeats into insights? This post breaks down ECG signal processing for heart rate variability — the same method used in research and wearables to reveal how your body responds to stress, rest, and recovery.
I’ve been tracking my heart rate variability (HRV) with my Oura Ring since 2018. Lately, the numbers haven’t matched how I feel — strong, consistent, and healthy. So I’m diving in: testing in my training load, Zone 2 cardio, intermittent fasting, and supplements in an attempt to positivly improve my HRV and recovery. This is…
This post serves as a comprehensive list for exploration into the factors influencing my Heart Rate Variability (HRV). This collection of questions delves into areas such as supplements, aerobic conditioning, caffeine effects, intermittent fasting, and stress management practices. The goal is to use these questions to drive my learning. This is my HRV “map” to…
