I finally figured out that my husband would get really cold getting in and out of the shower. Their thermostats don’t seem to work right anymore.
You could try a bath robe for her to wear to and from the shower. Get the shower nice and warm first then go in and help her wash her hair and body, quick rinse, back into the robe and a pair of slippers until she is completely dry. Then dress her in something nice and warm or cover her with a blanket. This worked for my Ernie for a while until he forgot how to walk.
Or you can get hospice on board. The patient doesn’t usually get mad at the nurses like they do us.

My husband says it is winter, he doesn’t sweat, so doesn’t need a shower. Got some of the foam you put on and don’t have to rinse and wipes. Sort of helps😏
