Is that OK to use iPone or iPod in the SAUNA?

I previously had a question about the electronic audio devices in the sauna. posted in the forum.

I got one reply about it over there.

The guy said that I may not have to worry about the heat.

H0wever, we need to concern the moisture.

In that case, the mist sauna is not really good for iPone or iPod.

I guess I do not have to worry about using cell phone in the dry sauna, but I rather not to use it there.
