8 hours standard sleep would just adapt. It's only 8 because it's a nice round number.

Very few people I know actually sleep exactly 8 hours, so the recommendation will just adapt to another memorable number.

It's 8 because it's 1/3 of the day. 10/3 is not a nice round number.

Also 1/4 of a day is 6 hours, another nice round number! 10/4 is 2.5 which is not as bad as 10/3 but still not a round number.
