Interesting. I'd put a question mark on that assumption.
I am doing way more physical activity than the average person (So I assume.)
Some days I'm burning more than 5,000 calories according to my fitness watch, yet I think it has been years since I've slept 9 hours or more(Maybe in some very irregular occasions)
I think that the fact that your body allows you to sleep more, doesn't necessarily means you "need" to sleep more.
In fact, oversleeping is sometimes linked with depression in some articles I've read somewhere in the web.
I do believe 7.5-8 hours are optimal - because I know a sleep cycle takes 1.5 hours and we need about 5.
That is also the "extreme"(8 hours) that even Ariana Huffington reverted to after her "Losing consciousness and breaking the face because of lack of sleep" crisis, which she described in her book "The Sleep revolution".
I guess you tried sleeping less than 9 hours previously. For how long did you go with it? What did you experience as a result?
P.S. Again, the fact that you "want" or "feel like sleeping" is not a measuring stick for me to an optimal sleep amount, because if it were, then also working, not playing games or working out would make no sense. But they do. :)
There might be something I don't know about you however, or that I don't know in general.
Feel free to disagree. Would love to hear your opinion.
