How Physical Exercise Level Affects Sleep Quality? Analyzing Big Data Collected from Wearables

Abstract

Physical exercise and sleep have independent, yet synergistic, impacts on the health. However, the effects of acute exercise level on sleep quality have not been well investigated. We utilize statistical methods to investigate the differences of exercise level between the good and bad sleep nights. Our results present a complex interrelation between physical exercise and sleep quality with analyzing large personal data sets collected from wearables. As far as we know, this is the first study to investigate insights of interrelation of physical exercise and sleep quality based on a big volume of data collected from wearable devices of real users.
