Because Northwood students are completing their schoolwork at home this semester, students are on their computers a good portion of the day. When school was in person, computers were often only used a fraction of the time spent in each class. Now, students must use their laptop to access all of their learning. They’re also often up late submitting assignments. Finishing assignments at night subjects students to copious amounts of blue light from their devices’ screens. Many students also are on other electronic devices at night. Large amounts of exposure to blue light have been found to have negative effects on teenagers’ health.
