"Every hour adolescents spend on social media after 10 PM increases their risk of severe daytime fatigue by a quarter," reports the Healthcare Weekly.
A study was conducted using a self-report questionnaire by researchers from the University of Midlands and the Youth Wellbeing Trust. Researchers identified significant correlations between the amount of time adolescents spent on screen-based media before sleep and their likelihood of experiencing daytime sleepiness, memory lapses, and poor academic focus.
Teens who used smartphones for more than 2 hours after 10 PM were 65% more likely to report poor sleep quality than those who limited screen time to 15 minutes or less. Those who active-chatted on messaging apps in bed were 82% more likely to experience daytime fatigue.
However, it must be noted that this cross-sectional study cannot prove direct causality. The reliance on retrospective self-reporting means participants had to recall media duration, which is subject to social desirability bias where teenagers might underreport their actual screen time. Furthermore, the survey was distributed online, possibly leading to a self-selection bias favoring heavy technology users.
