Staring at the screen for a long time will reduce the amount of sleep time and if the duration of sleep decreases, it means that one's sleep quality also decreases.

The number of respondents was 34 people. The instruments used were Internet Addiction Test (IAT) and Pittsburgh Sleep Quality Index (PSQI) questionnaire.
