Winters here, and in Canada, get very cold. So we rely on artificial heat to warm our homes. The artificial heat dries the air out like crazy. Relative humidity drops drastically. Our enclosures also need artificial heat. Again, dries enclosures right out. So the combination makes things more difficult and more expensive.
Your dessert climate is very different. That's why there's no "one size fits all" answer to many questions regarding husbandry.
I'm by no means saying it's not possible. I'm just saying there are easier and more economical ways.
