The negative effects of blue light from digital screens in interior spaces and its impact on sleep

The prevalence of digital screens in modern interior spaces has raised concerns regarding their impact on human health, particularly sleep. Blue light emitted from these devices has been shown to disrupt circadian rhythms and suppress melatonin production, leading to sleep disturbances and long-term health consequences. This research explores the negative effects of blue light exposure from digital screens in indoor environments and its specific impact on sleep quality. Utilizing a mixed-methods approach, the study combines a comprehensive review of existing literature with empirical investigations, including surveys and experimental data, to understand the extent of the problem and identify mitigation strategies. The findings underline the importance of minimizing blue light exposure in the evening and adopting technological and behavioral interventions to improve sleep health. Additionally, this research highlights the role of design and technological innovations in promoting healthier lighting environments for optimal sleep quality and overall well-being.
