What is the healthy amount of sleep that a school-aged child should be getting?

Variable. Growing or active kids with sports or heavy study schedules need a minimum of 9 hours. After growth stops and schedule lessens, most can get by on 8, some adults 6-7. Memory difficulty, diminished work or physical performance or drowsy periods during the day suggest the need for more sleep. Bedtime is based on lifestyle and schedule.A shift worker is different from a daily worker.
HEALTHY SLEEP. Used to be 8 hours or at least 6 to 8 hours uninterrupted sleep.
