🔹 Did you know your heartbeat holds valuable clues about your health, stress levels, and recovery?
🔹 Heart rate variability (HRV) is more than just a number—it’s a powerful signal revealing how well your body adapts to stress and daily life!

In this episode, we explore why HRV has become a key metric in health research, from tracking recovery in athletes to assessing stress and chronic disease risk. With modern wearable technology, HRV can be measured using simple PPG sensors on the wrist or more precise ECG devices, giving researchers a deeper understanding of autonomic nervous system function. We also break down different HRV analysis methods—time-domain, frequency-domain, and nonlinear analysis—and how each provides unique insights into physiological resilience and recovery.
