How does sleep affect my mood and schoolwork?

You're staying up late, waking up drained, and running the whole day on fumes and irritation.

• Teen brains need roughly 8–10 hours; most teens get far less.
• Sleep is when memory gets stored — losing sleep after studying erases part of the work.
• Screens at night delay the melatonin that starts sleep.

Before you decide anything, take four slow breaths — in for 4, out for 6. You think more clearly on the other side of a calm breath than in the middle of a fast feeling.

1. 1Set a phone curfew 45 minutes before bed and charge it across the room.
2. 2Keep wake-up time consistent, even on weekends. That's what stabilizes your rhythm.
3. 3Move your hardest studying earlier and protect the last hour of the night.

Move your phone charger away from your bed tonight.

Play it forward. If you take this step, what happens tomorrow? Next week? What does it protect — your peace, your grades, your relationships, your future? Leaders think one move ahead.
