Extensive studies have found that sleep in spaceflight is often reduced in duration and of reduced quality, which Earth-based studies show can reduce waking cognitive performance. doi: 10.1371/ must maintain a high level of cognitive performance capability in spaceflight, which depends on their acquiring adequate daily sleep quantity and sleep quality while in space, and on their ability to respond quickly and effectively to emergency events that can occur when they are asleep. doi: 10.5664/jcsm.3272Ĭhristensen MA., Bettencourt L., Kaye L., Moturu ST., Nguyen KT., Olgin JE, et al., Direct Measurements of Smartphone Screen-Time: Relationships with Demographics and Sleep.

Public health projects may benefit from combining citizen science with other interventional approaches. Using citizen science and mass media appeared to be associated with changes in night-time smartphone behavior. The reduction in sleep problems (54%), recognition of poor smartphone behavior (48%), and the increased focus on night-time smartphone use (42%) were motivational factors for these behavior changes. The participants who had changed their smartphone behavior had primarily taken active precautions to avoid night-time smartphone use, e.g., activating silent mode (36%) or reduced their smartphone use before (50%) and during sleep hours (52%). A total of 15% of the participants who used their smartphone during sleep hours at baseline had changed their night-time smartphone behavior, and 83% of those indicated that they used their smartphone less at follow-up. A follow-up survey aimed at evaluating whether survey-participants had changed their night-time smartphone behavior was carried out two weeks after the campaign. The survey was carried out for one week in 2018, combined with an extensive national mass media campaign focusing on smartphone behaviors and sleep. A total of 8,894 Danish adults aged 16 and above participated in the SmartSleep Experiment, a web-based survey on smartphones and sleep behavior. This study aims to evaluate whether a massive public focus on sleep and smartphone use generated through a large-scale citizen science project, the SmartSleep Experiment, influence participants' night-time smartphone behavior. The increasing 24-hour smartphone use is of public health concern. ![]()
