Humidity questions

[GyGbeetle]

I recently had a bout with mites, so I followed standard protocol of having everyone on paper towels. But one of my baby boas seemed to be really dry, and had a really hard time with her shed. So we bathed her in warm water, and tried spraying down her enclosure (like we do with our forest floor bedding. Her clutch mate shed a few days before her without incident. So we broke protocol and after 3 weeks on paper towels, put moist forest floor substrate back in. And bathed her while helping her shed.

My question is whether this is normal. She has a water bowl in her enclosure at all times, and she can soak her entire body in it. But she wasn't doing that as often as her clutch mate had done, or any of the other snakes for that matter. She seems to be ok now, a lot more moist since putting the substrate back in. Temps are all good and she eats just fine. The only thing I could think of was the paper towels just weren't providing enough moisture in her enclosure.
