PENGARUH DURASI MENGGUNAKAN SMARTPHONE TERHADAP KUALITAS TIDUR MAHASISWA FAKULTAS KEDOKTERAN UNIVERSITAS MUHAMMADIYAH MALANG

Background: The quality of sleep among medical students was important because it could affect students' academic performance. Insufficient sleep affected alertness and caused a decrease in attention, which slowed down cognitive processes. Furthermore, lack of sleep disrupted the functions of the prefrontal cortex and hippocampus, which affected memory, language, creativity, logical and critical reasoning. Research showed that 95.8% of medical students had smartphones for academic purposes, and about 84% of medical students believed that mobile health applications were very useful for learning, information search, and academic performance. Smartphone use could disturb sleep because blue light exposure could suppress melatonin hormone. Using smartphones for more than two hours before sleep resulted in poor sleep quality.
