I've been led to believe the daily shower is a mostly American thing.
Myself, I shower most days, but that's largely because I'm either in the gym or cycling most days. Sometimes, that means 2x showers, because I'll hit the gym in the AM and cycle in the PM.
Yes, American, indeed. It is a culture of the natives of the Americas to shower (swim in rivers) multiple times a day. Brazilian culture is highly influenced by that. We also brush our teeth multiple times a day.
Showering everyday is connected to atopic eczema and allergies. Your skin is the first element of your immune system and showering every day with soap is unnatural and damaging to your skin.
Could be that if I stopped showering for an extended period of time these issues would resolve, but… if I don’t shower daily my eczema quickly explodes out of control, worsening with each day.
Presumably it's also heavily influenced by climate, job and location?
Working in dirty or dusty conditions for example, or if you have a long commute in and out of the city on a train, you don't really want to skip having a shower.
I do the cold-water face splash every day, it wakes me up good. Can recommend.
I can't shave without showering afterwards though, I get itchy (maybe only psychologically) from the (idea of the) little shaved bits dropping on my skin and staying there under my clothes all day. It's one of the very few things I'm "funny" about.
I can't shave comfortably without showering first. Get the hairs soaked for a smoother shave. I wet shave, so all shaved bits get gathered in the razor which gets rinsed of in the basin.
