How to prepare salad bowl for the desert?

I just got a beautiful salad bowl in a humid country, but I have to take it home to the high desert, about 20%RH. I'm afraid it will shrink and crack badly. What should I do for it?

Oil it?

Wrap it up in plastic bags for a few weeks or months so it dries slowly? I don't even know if it was properly dried before being sold.

Something else?

How old is the bowl?  I think they are generally made from green wood otherwise it would crack before the bowl could be made.  Once it's "turned" or made, it dries out pretty quickly.  Instead of cracking, the bowl just flares open or closed a bit.

So if the bowl is more than 2-3 months old, I'm guessing it won't need any attention.  If it's younger than that, the bag idea is probably what I'd do for a month or two.  But hopefully someone with more know-how chimes in...

On second thought, if it's at 60% moisture content when they make the bowl, and it dries out pretty fast once it's turned into a thin curvy bowl, it's probably used to dramatic moisture losses.  So after a few weeks, moving it somewhere drier may not be a big deal.

Apparently I don't really know.  Sorry
