Question about "でも" in this particular sentence


So my question is about this " **でも** "

> 眠れないもので顔 **でも** 洗ったら少しはいいかと思って…

I think i know what the sentence means :

> "Because i was unable to sleep, i thought washing my face/splashing water on
> my face a bit would have been a good idea.."

But even do i get the overall meaning of this sentence, i was unable to
explain what this "でも" meant here precisely..

Is it "-or something like that" ?

Is it use because otherwise the sentence would mean that the guy/girl took a
COMPLETE shower?

How can i be sure of the PRECISE meaning?

Thanks!

edit : **Yes, this でも means "or something like that", indicating face washing
is not the only option.** <- this feel like a good additional information to
keep.




Yes, this でも means "or something like that", indicating face washing is not
the only option. Although this でも is placed between 顔 and 洗う, it means "(I
should) do something like face-washing" rather than "(I should) wash something
such as my face". The sentence means he/she could do something totally
different to kill time and get relaxed, like watching TV, cleaning his room,
or whatever.
