There is an emerging use of devices and wearables for tracking a variety of daily behaviors such as sleep quality and calorie counts. While tracking such behavior has proven to be beneficial for physical health, less is known about the benefits of tracking mental health. This paper examines the impact of tracking daily emotions on emotional and subjective well-being. Two longitudinal studies (N = 1025) show that tracking people's emotions (i.e., reporting and reminding participants of their past emotions) has an asymmetric persistence effect, such that positive (but not negative) emotions are more likely to linger the next day. The results shed light on the importance and benefits of tracking emotions for improving consumers' mental health.

越来越多的设备和可穿戴设备用于跟踪各种日常行为，例如睡眠质量和卡路里计数。虽然追踪此类行为已被证明对身体健康有益，但人们对追踪心理健康的好处却知之甚少。本文研究了跟踪日常情绪对情绪和主观幸福感的影响。两项纵向研究（N  = 1025）表明，跟踪人们的情绪（即报告和提醒参与者过去的情绪）具有不对称的持久效应，因此积极（而非消极）情绪更有可能在第二天持续存在。研究结果揭示了跟踪情绪对于改善消费者心理健康的重要性和好处。
