No hygroreceptors - we use a combination of temperature and texture. That’s why if you touch hanging laundry on a cold day, it’s very hard to determine if it’s wet or just cold.
EDIT: having looked through the comment and link that u/foggy-sunrise shared, I think the shower thought was more a shower fiction. Please read it!
