Canadian students are trading their grades for screen time: Here’s what students need to know

A groundbreaking Canadian study has unveiled an alarming link between children’s screen time and their academic decline. Tracking over 5,000 students for 15 years, researchers found that each additional hour before a screen can lower grades by up to 10%, particularly in maths and reading. The findings warn that digital convenience may be quietly eroding cognitive growth, focus, and problem-solving abilities—raising urgent questions about the long-term cost of early digital immersion.
