UNLESS you work a blue collar job, or any other job that requires you to be outside the whole time, I don’t see the point in showering every day. Especially if you work from home or in a building with AC. It seems excessive and is also a waste of water. But do what you want lmao.
I work from home for my main job (desk job) and still sweat; I also try not to over-use my air conditioning. Additionally, I have to mow (though the goal is to continue reducing grass in favor of edible plants, it takes time), do other work around the house, and do small-scale farming.
All of that nonwithstanding, I’ve gotten into the habit here in Japan of not getting in to bed dirty. I don’t wash my sheets every single day, so I wash me before getting into bed rather than stewing in bacteria, fungi, pollen, etc. for a week or more at a time. Additionally, a hot bath before bed helps me relax and get ready for sleep (though I skip it sometimes in the worst parts of summer). My sleep quality is also now better than it used to be.
