Abstract

Introduction: Blue light, emitted from digital screens, LED lights, and the sun, plays a crucial
role in regulating the sleep-wake cycle but can negatively impact sleep when excessively exposed
at night. Adolescents are particularly vulnerable due to prolonged screen use and natural shifts in
sleep patterncycle.
Objectives: 1)Toassess theimpact ofbluelight screen amongadolescents 2) To assess the sleep
quality and behavioral problems among adolescents. 3) To determine the correlation between the
impact of blue light screen and qualityof sleep amongadolescents. 4) To determine the correlation
between the impact of blue light screen and behavioral problemsamong adolescents 5) To
determine the correlation between sleep quality and behavioral problems among adolescents 6)
To associate the impact of blue light screen, sleep quality and behavioral problems with the
selected demographic variables.
Methodology: A quantitative descriptive study was conducted among 100 adolescents at Chetpet
Government High School using purposive sampling. Data were collected using a standardized
questionnaire, including the Strengths and Difficulty Questionnaire (SDQ) and Pittsburgh Sleep
Quality Index (PSQI) scales, Anda nalyzed through descriptive and inferential statistics.
Results: Amongadolescentsaged12–18 years, 81% had moderate exposure and 19% had high
exposure to blue light screens. About 74% experienced poor sleep quality, while 26% reported
good sleep. Additionally, 52% showed high levels of behavioural problems, and 48% had low
levels. A poor, non-significant positive correlation was found between blue light exposure and
both sleep quality (r = 0.097) and behavioural problems (r = 0.063). However, a fair positive
correlation was observed between sleep disturbances and behavioural issues (r =0.331, p≤0.001).
Gender and sleep duration were significantly associated with sleep quality, while age was
significantly associated with behavioural problems. No demo graphicvariables were significantly
linked to blue light exposure levels.
Conclusion: The study concluded that greater exposure to blue light screen is associated with
increased behavioral issues, which in turn aggravatessleep disturbances among adolescents.
