I was reading this article...

I was reading this article on sleep, which has nothing to do whatsoever with Superman until you get to the last paragraph, then you'll see why I posted it.

So...Superman doesn't have to sleep very much because he is a herbivore, as Birthright says.

Thanks, Jerome Siegel!

That's a funny coincidence.

That article said that herbivores need to eat all day & that they nap when they can.  Then there is the fact that most herbivores are prey for carnivores.  The life of a herbivore: constantly eating while trying to avoid being eaten.  No wonder that they only nap when they can.

I've always thought that while Superman shouldn't physically need sleep, he would mentally. I see him getting about two hours of sleep each night. He has to always be prepared in case of an emergency.

Additionally, I'd think that he'd have his Superman robots fly around the Earth when he's either sleeping or posing as Clark Kent. It would create the illusion that Superman is always active.

It's been stated that Superman DOESN'T need sleep, but he DOES need to dream, just like humans.  

That's why he WOULD take the time to go to sleep.

I think it says in Miracle Monday that he can sleep hemispherically like a dolphin.
