Relationship Between Sleep and Nutrition with App Data: A Large-Scale Study

Diet and sleep, which are essential for human survival, are interrelated. However, recently, various services and mobile applications have been introduced for the self-management of health, allowing users to record and gather data on their eating and sleeping habits.

In response to these trends, this study examined the relationship between nutrients and sleep using data from people who simultaneously used the dietary management application "ASKEN" (Asken, Inc.) and the sleep game application "Pokémon Sleep" (Pokémon, Inc.). The analysis utilized 14 nutrients quantified from daily diet records in ASKEN and the total sleep time, sleep latency, and wakefulness after sleep onset obtained from the three-axis accelerometer data built into smartphones in Pokémon Sleep. Data from 4,825 users, who gave their consent, were analyzed considering the interdependence of the major nutrients. The results showed that (1) the higher the total energy, the shorter the total sleep time and the longer the wakefulness after sleep onset, (2) participants with high protein intake had longer total sleep time, (3) participants with high intake of monounsaturated fatty acid and polyunsaturated fatty acids and (4) those with high intake of polyunsaturated fatty acids have shorter sleep latency and wakefulness after sleep onset, whereas those with high intake of monounsaturated fatty acids have longer sleep latency and wakefulness after sleep onset, (5) participants with high dietary fiber intake have longer total sleep time and shorter sleep latency and wakefulness after sleep onset, and (6) participants with high sodium intake (high sodium-to-potassium ratio) had shorter total sleep time and longer sleep latency and wakefulness after sleep onset.
