Can you imagine taking a nice hot shower and being afraid to dry off? I imagine that your clothes would be kind of hard to put on. I also bet that wet hair would probably be pretty hard to deal with in the winter. Then there is the problem of how do you avoid inevitably air drying? How does a xerophobe manage to stay wet? Do you carry a spray bottle at all times? Or are xerophobes just constantly applying lotion?
The answer to all of those questions is I don't know. Throughout my list of bizarre fears from A to Z this one is one of the more weird ones that I have covered. I have many more questions than answers on this one. I suppose being afraid to be dry would have some benefits. For example, one benefit to being afraid to be dry would be all the money you'd save on towels. Towels are expensive. Especially if you like a high thread count. Plus just think of the money you would save on your electric bill never having to worry about drying your clothes. Come to think of it, doing dishes would take half the time without all that pesky drying of the dishes. So, while I may not understand being afraid to be dry if you are not a fish, it clearly has a few advantages.
