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.
Showers really should work like dishwashers. Basically fill a reservoir, filter, re-heat, and recirculate that water a few times. Could also slowly drain and replace a bit of it throughout or have discrete wash/rinse cycles.
Most of the water used when I shower is just standing there because the hot water is relaxing.
Maybe if you had dried on crusted food.
Navy shower also helps break the standing there mentality.
