Sleep, Six to Twelve

The idea
The American Academy of Sleep Medicine recommends nine to twelve hours of sleep a night for children aged six to twelve.
In practice
A well-rested child remembering more of the day's lesson, since sleep consolidates learning and releases growth hormone.
Where people slip
Occasional disruptions are normal; persistent sleep problems carry emotional, behavioural and school risks, and short sleep harms focus.
