🧠 Can AI and Wearables Transform Heart Function Research?

In this episode, we explore how body position, physical activity, and AI-enhanced HRV data are revolutionizing heart function research. Wearable devices now track posture shifts—sitting, standing, lying down—and physical activity levels in real time, allowing researchers to analyze how these factors influence heart rate and autonomic function. Machine learning plays a key role by detecting patterns, predicting recovery trends, and identifying conditions like Postural Orthostatic Tachycardia Syndrome (POTS). Whether it's monitoring athletes' training adaptations or assessing the risks of prolonged sedentary behavior, AI-powered wearables provide continuous, real-world cardiovascular insights like never before.

📊 How Can We Capture Human Experience in Real Time?

In this episode, we dive into the Experience Sampling Method (ESM)—a research technique that captures momentary experiences, offering deeper insights into human behavior. Unlike retrospective surveys prone to memory bias, ESM gathers real-time data through smartphones, apps, and other digital tools. This method helps researchers understand daily life with unmatched accuracy, making it invaluable for psychology, healthcare, and behavioral science. We also explore different ESM approaches, from event-contingent to signal-contingent sampling, and discuss how technology is transforming its applications.
