If you could help me and 25% of everyone [1] figure out that underlying problem, we would be super grateful!

Or perhaps not, considering there are cultures where a noon or early-afternoon nap is not particularly out of the ordinary. No one's really talking here, in any case, of needing a daytime nap, but rather of finding one beneficial to productivity.

Wow, really? Not only does daytime napping improve health even if you are already healthy adult who gets adequate sleep, there's ample evidence our (pre-working in an office for 10 hours straight) ancestors did so regularly, which persists in many cultures to this day.

I suggest you recalibrate your definition of "normal".

Offices are much less natural than afternoon naps.

Yes, work is not "natural", but we have to sit and do it every day because that's the way it is. So the problem here is to find tricks to keep being productive all day long, and naps are one of them.
