With all the technological advancements of the last twenty years and the rise of social media in the last ten years, it is not unreasonable or inconceivable to suggest that electronic media devices Bedrooms present in children and adolescents inhibit normal sleep processes, leading to fatigue at school and the onset of delayed sleep phase disorder (DSPD). A growing number of studies from around the world support this theory, only a few of which will be cited in the following essay. Growing evidence shows that children and adolescents with electronic media devices in their bedrooms have poorer bedtime and sleep habits and poorer sleep quality than those without them. . The first article discussed in this essay is written by Suganuma, Kikuchi, Yanagi, Yamamura, Morishima. , Adach, Kumano-Go, Mikami, Sugita and Takeda (2007) is one of the most fundamental studies in terms of content and in relation to other studies, but also one of the most important to mention. They used a series of surveys and questionnaires to assess the level of insufficient sleep they perceived attributed to the use of electronic media devices before attempting to fall asleep one night. Their results showed that those who used electronic media consistently reported insufficient sleep and sleep deficits. A study by Pieters, De Valck, Vandekerckhove, Pirrera, Wuyts, Exadaktylos, Haex, Michiels, Verbraecken, Cluydts (2012) suggests that there is a biological change in the circadian rhythm of adolescents and that the onset of sleep and waking up is delayed, leading to later bedtimes and getting up times. A number of environmental factors are also mentioned in relation to these biological factors regarding the consequences...... middle of paper ......fr that lead to sleep deficits and DPSD. It also informs parents, teachers and health professionals that watching television and using a computer in particular can lead to negative sleep patterns, resulting in daytime sleepiness at school, attention and behavior problems , as well as increased risk to mental and physical health. This supports the recommendation that parents should exercise more monitoring and control over their children's daily exposure to electronic media devices. The article by Nuutinen, Ray, and Roos offers a good comparison with most other studies in this area, as they tend to focus on media use among adolescents. But it is important to note that exposure to electronic media is also increasingly high among children, which can consequently lead to the pathological use (King, Delfabbro, Zwaans, Kaptsis, 2013) mentioned above as they become adolescents..
