Social media for students' sleep health promotion - a health intervention report during COVID -19.

The COVID-19 pandemic has affected sleep health. Students' sleep health is essential for the performance of neuro-cognitive processes, as well as mental and physical balance. We assume the COVID19 pandemic has modified some sleep habits by prompting environmental and social interaction changes. In this study we surveyed a sample of 300 Brazilian students, with internet access, resident in the Federal District. They completed a questionnaire over two weeks in March 2020, i.e. the second and third week of the social isolation policy enacted in the Federal District due to COVID19. Valid responses from students aged18-24 years were analyzed. The sample was mostly female; 76,3% reported somnolence during the day, 70,2% anxiety and 87,8% worse sleep associated with stress and/or anxiety, which indicated the variables for an educational health intervention design in this context. Further, 53.2% made no effort to avoid screens before sleeping; 73.9% to avoid using the bed for work or watching television and 83.1% to avoid consuming heavy foods before sleeping. We then created an Instagram profile, @comodormimos, which focused on the main sleep issues revealed by participants in the survey. Posts on the profile were based on sleep-related subjects: sleep processes, sleep hygiene practices for students; sleep stages, function and regulation; and sleep-wake circadian rhythms. The profile gained 307 followers, mostly women (61,7%), 18-24 years old. We concluded that the Covid-10 pandemic period increased harmful sleep behavior in students. Further studies are needed to understand the impact of the COVID-19 pandemic on student sleep health.
