It's different for every person..
but for me..
I live in the Netherlands, and this is a moderate sea climate... it's often quite cold and windy~
We don't sweat a lot :P
Besides that, taking a bath every day is a waste of water and money..
it's unnecessary to shower every day because we don't get dirty :P
And also... taking a bath every day is not good for your skin and your hair XD My hair can be quite a struggle to get ready if it's wet XD
But! In the summer I like to take a bath every day~
Or I take a bath every day on another occassion (when I'm dealing with a certain problem)....... you don't know what I mean~ :P
