Viva Bem Sleep stages determination dataset

This dataset includes information about individuals who wore Samsung Smartwatches (GW4/GW6) during sleep while undergoing a full polysomnography exam. The dataset provides insights into sleep quality and its relationship with activity patterns, including data on physical activity, heart rate, body composition, stress, and sleep, all captured through the Samsung Health system. The data collection for this study took place in both free-living and controlled environments. Participants were given a smartwatch to wear throughout the day to track metrics, including daily step count, heart rate, body composition, and stress levels. They were instructed to wear the smartwatch during sleep for analysis of their sleep patterns. After a week of free-living data collection, participants visited the Sleep Laboratory at Unicamp for polysomnography, a comprehensive test involving multiple sensors to record brain activity, eye movements, muscle activity, respiratory function, and other physiological parameters. This study combines data from wearable technology and polysomnography to investigate the relationships between sleep quality and daily activity levels. The generalized medical reports and corrected polysomnography temporal data are also included as metadata. Due to privacy and ethical considerations, only a portion of the dataset may be publicly available. Researchers interested in accessing the full dataset must contact the authors and submit a formal request, which will be reviewed on a case-by-case basis to ensure compliance with privacy regulations and ethical standards. The PGD is made available here.
