| Aspect | Recommended Amount | Key Characteristics | Practical Tips | |--------|--------------------|----------------------|----------------| | | 9–12 hours (American Academy of Sleep Medicine) | Deep, restorative sleep cycles; consistent bedtime/wake‑time | Set a regular bedtime (e.g., 8:00‑9:00 pm) and keep it even on weekends | | Sleep environment | Dark, quiet, cool (≈65‑68 °F / 18‑20 °C) | Minimal light exposure; comfortable mattress & bedding | Use blackout curtains, a white‑noise machine or fan, and limit bedroom electronics | | Pre‑sleep routine | 30–60 min calming activities | Reading, gentle stretching, or a warm bath | Create a predictable “wind‑down” ritual; avoid screens at least 30 min before bed | | Screen use | No screens within 30 min of bedtime | Blue light suppresses melatonin, delaying sleep onset | Offer non‑screen alternatives (puzzles, drawing) in the bedroom | | Daytime naps | Generally not needed for most 8‑year‑olds | If a child still feels fatigued, a brief (20‑30 min) nap can be restorative | Encourage a short rest in a quiet space, but avoid long afternoon sleeps that interfere with nighttime rest |
