Where this number comes from
Published guidance retrieved by age and source, keeping each source’s own basis for the figure.
Step by step
Matched by age and source, and always stated as 24-hour total, night-time only, or naps included — bodies differ on this, and without it two figures cannot be compared. Each source stands on its own; nothing is averaged.
What this number cannot tell you
A recommended duration is a range, not a pass mark. Nothing here assesses a sleep disorder or suggests medication or treatment.
An example
At 7 years 6 months: China’s MOE says at least 10 hours a day, while the CDC and Japan’s MHLW both give 9 to 12 hours.
Common questions
- Why is there no number?
- There is no figure here that can be given with confidence, so none is given. The normal range for questions like this is wide anyway — a few minutes with a paediatrician or dentist usually settles it.
- What if my child’s age or country is not covered?
- It will say plainly that this age is not covered, rather than borrow figures from another age or another country. How far a standard reaches is set by whoever published it, and stretching it gives a placing that is simply wrong.
