A Descriptive Study on Blue Light Exposure, Sedentary Work Patterns, and Emotional Well-being among IT Employees

Abstract This descriptive cross-sectional study examines patterns of blue light exposure, sedentary behavior, and emotional well-being among IT employees, a population characterized by prolonged screen dependence. Data were collected from 150 IT professionals aged 25–45 years using the Light Exposure Behavior Assessment (LEBA), the International Physical Activity Questionnaire–Short Form (IPAQ-SF), the WHO-5 Well-being Index, and the Bodily Perception Questionnaire–Autonomic Nervous System Subscale (BPQ-20 ANS). Descriptive statistics revealed notably high daily screen time (M = 9.1 hours, SD = 1.5), substantial post-6 PM blue light exposure (M = 3.8 hours, SD = 1.1), and prolonged sedentary periods (M = 9.8 hours/day, SD = 1.8). Emotional well-being scores averaged below the clinical threshold for good well-being (M = 11.2, SD = 3.2), and autonomic symptom scores (M = 19.5, SD = 6.1) indicated frequent stress-related bodily sensations. The descriptive patterns suggest that prolonged screen exposure, late-evening blue light intake, and extended sedentary work may coexist with reduced psychological and autonomic well-being in IT professionals. The findings highlight an urgent need for ergonomic redesign, screen-use regulations, and workplace-based mental well-being interventions tailored to digital work environments.
