We spend less time sleeping today than our ancestors did, and lack of sleep has consequences for health, immune systems, and cognitive functioning. One way to combat increasing “sleep debt” is to take short naps. We asked 29 people to listen take a 20-minute nap each day for two weeks, listening either to pzizz or to one of several competitors’ soundtracks. Importantly, people were “blind” to the condition: they did not know what soundtrack they were listening to. Before and after each session, we asked them questions designed to tap into various aspects of their well being. By the second week, we found that people who listened to pzizz reported significantly more improvements in well-being compared to people who used competitors’ products.
