Sleep technology is everywhere. Trackers, sleep kits, and headsets all promise to help you achieve a better night’s sleep. These options seem to be getting more technologically advanced, and provide you with more information. So what could be the problem?
Well, more information isn’t always a good thing if we don’t know how to interpret it. Sleep trackers are becoming more accurate, but our research about how to read and address the data it gives just hasn’t caught up. “I do not believe that decontextualized information about one’s sleep is at all useful,” said Jamie Marc Zeitzer, a professor of neuroscience and sleep at Stanford University. “It might be fun for a few nights, but without other information, it leads to uninteresting suggestions like ‘try getting more sleep.’”
