Comparative Study on Behavioural Changes in Mice Exposed to ProlongedBlue Light Radiation

The effects of long term exposure to blue light on a range of behavioural parameters in mice, such as anxiety, locomotor activity, cognition, and sleep patterns is explored in this study. Male mice (30) were subjected to 4 or 8 h of exposure to the blue light every day for two weeks while the control group was kept under normal lighting. To understand anxiety, motor functions, cognitive flexibility, and circadian rhythms, the Open Field Test, Elevated Plus Maze, Y-Maze, and Wheel Running Test was carried out to assess behavioural attributes. The outcomes proved that long-term exposure to blue light caused strong decreases in the locomotor activity and cognitive performance and caused the increase in the anxiety-like behaviours and the interruption of the normal sleep-wake cycles. The results indicate that chronic exposure to blue light may be harmful to both mental and physical health, and may have ramifications for the body particularly with regards to contemporary lifestyles that are reliant on digital-screen and artificial light. This study implies necessity of conducting further researches on long-term influence of blue light on behaviour and the necessity of managing one’s exposure to avoid possible risks.
