Sleep, screen time, and healthy habits
Aligned to NHES 7 — SHAPE America National Standards.
What this lesson teaches
Teens need about 8 to 10 hours of sleep, but screens and busy schedules often cut that short. Too little sleep hurts your mood, focus, and even your physical growth. Building habits like a screen-free wind-down and charging your phone outside your room protects your health and your school performance.
Worked example
Try putting your phone on a charger in another room an hour before bed and reading or listening to music instead, so your brain can wind down and you fall asleep faster.
Practice questions
- How many hours of sleep do teens need?
- Name one way screens hurt your sleep.
- Describe a healthy wind-down routine for bedtime.

Sueño, tiempo de pantalla y hábitos saludables
Los adolescentes necesitan entre 8 y 10 horas de sueño, pero las pantallas y las agendas ocupadas suelen reducirlo. Dormir poco afecta tu estado de ánimo, tu concentración e incluso tu desarrollo físico. Crear hábitos como desconectarte de las pantallas antes de dormir y cargar tu celular fuera de tu cuarto protege tu salud y tu rendimiento escolar.
Ejemplo: Intenta poner tu celular a cargar en otro cuarto una hora antes de dormir y en su lugar lee o escucha música, así tu cerebro se relaja y te quedas dormido más rápido.
