Hubungan antara Screen Time (Waktu Layar) dan Kualitas Tidur di Kalangan Mahasiswa: Tinjauan Pustaka mengenai Revenge Bedtime Procrastination, Fear of Missing Out (FOMO), dan Dampak Akademik

Abstract

Abstract

Introduction: The rapid development of digital technology has increased the use of smartphones, laptops, and social media among college students. High screen time, especially before bedtime, is associated with poor sleep quality. Excessive exposure to digital devices may disrupt sleep patterns through biological and psychological mechanisms, including blue light exposure, Fear of Missing Out (FOMO), and revenge bedtime procrastination. Methods: This study used a literature review approach by collecting articles from Google Scholar, PubMed, and ScienceDirect published between 2021–2026. The keywords used included “screen time,” “sleep quality,” “blue light,” “smartphone addiction,” “FOMO,” and “revenge bedtime procrastination.” Selected articles met inclusion criteria related to college students and sleep quality. Results: The reviewed studies showed that excessive screen time was associated with increased sleep latency, insomnia, circadian rhythm disturbances, reduced sleep duration, and daytime dysfunction among students. Blue light exposure suppresses melatonin production and interferes with the natural sleep cycle. Discussion: Psychological factors such as FOMO, smartphone addiction, and revenge bedtime procrastination contribute to prolonged nighttime device use. Poor sleep quality negatively affects physical health, mental health, concentration, learning productivity, and academic performance among college students. Conclusion: Excessive screen time significantly affects sleep quality among college students. Proper sleep hygiene and better control of digital device usage are important to maintain students’ health and academic performance.
