Abstract
There is an increased screen time among medical college students in India. This is a huge concern. Therefore, it is of interest to report an update on the relationship between screen time and cognitive performance, specifically choice reaction time (CRT), among 147 undergraduate students aged 18-25 years. The results indicate a significant positive correlation between increased screen time and prolonged CRT, suggesting that excessive screen use negatively affects cognitive responsiveness. Additionally, screen time was found to be inversely correlated with sleep duration, pointing to disrupted sleep as a potential mediator for cognitive decline. No significant gender differences were observed in CRT, highlighting the universal impact of screen time on cognitive function. These findings emphasize the need for balanced screen use and adequate sleep to maintain optimal cognitive performance in young adults.
