I don’t think I’ve ever heard someone describe taking a shower as “removing impurities” but hey if that’s your intended meaning then cool!
For your future reference, “impurities” is kind of a catchall, meaningless term that health quacks throw around. “Do a juice cleanse, it’ll remove your impurities and toxins.”
Don't sweat it, you just unfortunately tripped up on a VERY charged word lol. Again, your advice is good! Getting the body moving and cardiovascular/pulmonary systems cranking is good for waking up and feeling energized. Showers just feel damn good too.
