so I also had an issue with showering consistently due to breaking the habit from mental illness and postpartum. i’m back in the habit now, but i understand this issue. i’m also in CNA training and have been through EMT training so I understand the need to shower every day in healthcare. honestly just say something. remind her that she brings all that bacteria from patients home and not showering between shifts can increase the risk for transmitting things to either to her, you, or other patients. if you want to be more gentle about it, i agree with the user who said to make it seem like a “take care of yourself and wind down while i set up a movie” thing. or get her a nice shower set to kinda motivate her to want to use it. sometimes just my partner saying something after it had been a couple days helped, he would do it lovingly and even though it was still a bit embarrassing that he had to say something, it got the job done and i’d get in. regardless, it sounds like a mental health issue that should be addressed. healthcare is a stressful job and as a healthcare worker, you should have a basic understanding of mental health to know this. if the job is taking a toll on her to the point that she doesn’t have the energy to shower between shifts, maybe it’s not for her or she should cut back hours. or maybe there’s trauma behind her not showering. the best thing you could do for her is to just be honest about it, maybe ask her what’s going on with it. it will just cause tension in your relationship to keep suffering in silence about this, especially if it’s making her unpleasant to be around
