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.
