Student Profile: Morgan (Age 14, Grade 9)
Morgan reports feeling tired throughout the school day, particularly during mid-day classes, and feeling irritable at home in the evening. Morgan states: "I head to my room by 10:30 PM every night, so I'm getting enough rest." Below is Morgan's actual device telemetry and sleep log from a recent Tuesday:

Health Science Context (Canadian 24-Hour Movement Guidelines): Health Canada and the Canadian Paediatric Society recommend 8 to 10 hours of uninterrupted sleep per night for teens aged 14–17. Blue light emitted by screens suppresses melatonin production for approximately 60–90 minutes after shutoff, delaying deep restorative sleep cycles.
Pair Analysis & Calculations
1. Sleep Debt Calculation
Target: 9.0 hours. Morgan obtained ~6.1 hours of rest. Calculate Morgan's single-night sleep debt and projected 5-day school week deficit:
2. Perception vs. Reality
Morgan believed they were getting rest by "heading to room at 10:30 PM." Explain why there is a gap between Morgan's perception and biological reality:
3. Multi-Dimension Impact
How does this sleep deficit affect Morgan's Mental/Emotional health and Academic performance?
4. Practical Boundary
Propose ONE realistic, low-friction change Morgan could implement tonight to gain back at least 60–90 minutes of sleep:
Looking at Morgan's pattern, what is one habit in your own routine (or among peers) that quietly reduces sleep duration or quality?
