The teaching consists of sleep education (sleep knowledge and good sleep routines), time management (e.g., planning homework without distraction, planning other activities, quiet time before bedtime), information to guardians, and discussions with peers in the classroom (e.g., rules regarding evening interaction via electronic media). Homework\u002Fexercises and behavioral experiments are also included.

The data collection consists of a digital questionnaire regarding sleep habits, insomnia, motivation, physical and mental health, and electronic media use; a selection of students will use the actigraph for a week. After the first week, the participants will be instructed to stop using screens 1 hour before their usual bedtime. After one week has passed, participants in the Technology restriction intervention will be asked to complete the previously mentioned questionnaires as well as questions about the intervention itself: its applicability, compliance, and whether or not they will continue to limit their screen time before bedtime. One year after the intervention, they will be asked to complete the same questionnaire as at baseline.
