Information overload and sleep disorders

Due to the processes of globalization and transition to the information society their negative effects started to become apparent, namely virtually unlimited access to an abundance of information. Information overload occurs when the amount of information exceeds the perceptual abilities of accepting human being. It questions the impact of this process on health and sleep. Such phenomena as mind scrolling, communicative overload, distrust of digital security, cyber violence, digital inequality as mediators or consequences of information overload are considered. This article reviews the types of the information overload, ways of disseminating information, mechanisms of influence on the self-rated health and psychological condition and sleep, connections with anxiety and depression. This subject became especially relevant in  the context of  COVID-19 pandemic, since isolation, restriction of motor activity, and increased time spent behind the screen have become important predictors not only of sleep disorders, but also of other health problems. The article addresses the issue of subjects of studies are usually teenagers and people under 35 (generation Z), as the most active smartphones, messengers, social networks and mass media users. The problem of providing unfair information to users of social networks of different regions of residence, socio-economic levels is raised. Most scientists agree that the ways to solve the described problems are to limit the time behind the screen, the amount of content consumed per day, and compliance with sleep hygiene. Additional studies are required to determine the exact pathophysiological mechanisms of the effect of stress on sleep.
