Summary
This cross-sectional study of 150 medical students found a significant positive correlation between blue light exposure from digital devices and poor sleep quality, suggesting that screen use habits among students are a meaningful target for intervention. Lighting designers and health educators should consider recommending blue light reduction strategies (e.g., screen filters, night modes, or device curfews) for student populations, where poor sleep prevalence was extremely high.
Key Findings
- 94% of students had 'bad' blue light exposure levels; 87.3% had poor sleep quality.
- Significant correlation between blue light exposure and sleep quality: p < 0.001, Pearson r = 0.663 (moderate-to-strong positive correlation).
- Sample was 64% female, 36% male, predominantly aged 21 years (58%).
