I hear you loud and clear! I HATE it! Always have. One theory I had was that it's genetic because my sister and my cousin both have the same aversion! We refer to the shower as the "water chamber" haha. Then I had a really goofy theory. My family is Syrian/Lebanese and our ancestors likely lived in dry desert conditions. Because water was such a limited resource it was wasteful to do things like bathe. So I figured they all took "sand baths". And I thought how funny because I LOVE being at the beach and laying directly on the warm soft sand. A sand bath! lol. Seriously though I understand and I feel less like a mature woman when I don't take basic care of myself. I'd never tell anyone! They'd think I was nuts so it was refreshing to see your post. My honest and serious theory about hating showers is that 1) I hate being cold. HATE IT. And 2) I'm very sensitive to things like loud noise or too many people in one place like at a party. The reason I think is because I feel kind of psychologically assaulted if that makes sense. Like it puts me on sensory overload. When I have to get in the shower I experience the same feeling and figured out that just the pounding of the water on my skin is just too much sensory input. It overwhelms me and God forbid if someone in the house flushes a toilet or turns on the hot water and suddenly the water is ice cold? It's a double whammy: cold AND tactile overload! Does any of this resonate with you? If not, try to pay close attention to your thoughts and feelings related to both your mental and physical state as you think about or get ready to take a shower. See if you can figure out what is happening that might help you identify what's influencing your feelings. It took me a long time to figure out my feelings of having sensory overload from the shower experience. And it kind of helps to understand it. At least I don't feel crazy or ashamed anymore. I hope this helps!
