The correlation of screen time with sleep quality: A cross-sectional study on undergraduate medical students

[5] Longer usage of mobile phones resulted in poorer sleep quality (delayed sleep phase, sleep duration, altered sleeping patterns, chronotype, and sleep quality), increased fatigue, and insomnia which, in turn, results in several mental health issues. [...]melatonin offers an alternative treatment to the currently available pharmaceutical therapies for sleep disorders with fewer side effects. The individuals who were undergoing medical treatment for any mental health disorders were excluded from the study. [...]sleep in multiple ways restores both normal levels of brain activity and normal "balance" among the different functions of the central nervous system.
