Sleep Hygiene and Disorders Among Gen Z: Assessing the Impact of Screen Time and Online Behavior on Sleep Quality and Overall Health

Abstract

The study examines the complex relationship between Gen Z's nocturnal technology usage and its effects on sleep hygiene, specifically how these behaviours affect health outcomes and economic productivity. A mixed-method research methodology was utilised to collect primary data from 174 respondents via structured questionnaires and in-depth interviews, alongside secondary data from peer-reviewed journals, governmental health statistics, and industry reports on digital consumption. The study investigates variables including screen time duration, types of digital content consumed, and online participation, which substantially affect circadian rhythms and sleep quality. Findings indicate that extended screen exposure prior to sleep is significantly associated with inadequate sleep hygiene, resulting in diminished cognitive performance, increased stress levels, and lowered overall efficiency. These disturbances result in negative health consequences and economic losses due to reduced academic and professional productivity, as well as heightened healthcare costs. The research highlights the necessity for focused interventions, including the enhancement of digital literacy and the regulation of screen time, to alleviate adverse effects and promote better health and economic stability for this population.
