The effect of blue light filter use on sleep quality, circadian rhythm, and psychological well-being

THE EFFECT OF BLUE LIGHT FILTER USE ON SLEEP QUALITY, CIRCADIAN RHYTHM, AND PSYCHOLOGICAL WELL-BEING

A randomized controlled trial examining the effect of evening blue light filter use on sleep quality, circadian rhythm, and psychological distress in young adults is ongoing, and data analysis has not yet been conducted.

The aim of the study is to evaluate the effect of blue light filter use on sleep quality, circadian rhythm, and psychological distress in young adults. The study is designed as an ongoing randomized controlled trial (RCT); the study population consists of young adults aged 18 to 30 years. The intervention involves enabling blue light filters on smartphones in the evening; the variables measured are sleep quality, circadian rhythm, and psychological distress, and pretest and posttest measurements will be compared across the intervention and control groups. A literature review was conducted using the PubMed, Scopus, and Web of Science databases. As reported in the poster, data collection is ongoing, and no statistical analysis has been conducted at this stage; therefore, no numerical findings have been presented. The authors expect that reducing blue light exposure may improve sleep quality, regulate circadian rhythm, and reduce psychological distress. The conclusion states that reducing blue light exposure through a simple smartphone setting may offer a scalable, low-cost strategy for improving sleep and mental health in the digital age.
