Human physiology is a window to our physical, mental, and emotional states; our well-being. Today, a new wave of objective data derived from consumer grade body sensors—like those equipped by smartwatches—paves the way toward a new approach in how well-being is being measured, continuously and unobtrusively. Here, we developed a framework for collecting and analyzing physiological data using smartwatches in-the-wild, and demonstrated its robustness in data obtained away from controlled laboratory settings. We found that changes in people's heart rate and heart rate variability are predictive not of momentary well-being (a scientific idea that continues to live on in the absence of in-the-wild evidence, aka, zombie theory) but of daily well-being.

WellBeat：使用智能手表跟踪日常幸福感的框架

人体生理机能是了解我们身体、精神和情绪状态的窗口；我们的幸福。今天，从消费级身体传感器（如智能手表配备的传感器）中获得的新一波客观数据为一种新方法铺平了道路，即持续且不引人注意地测量幸福感。在这里，我们开发了一个框架，用于在野外使用智能手表收集和分析生理数据，并证明了其从受控实验室环境中获得的数据的稳健性。我们发现，人们心率和心率变异性的变化不能预测一时的幸福感（一种在缺乏野外证据的情况下继续存在的科学思想，也就是僵尸理论），而是对日常健康的预测——存在。
