Is it normal to shower once every 2 days?
Yep.Totally normal
Yes, showering every two days is normal for many people. How often you need to shower depends on your activity, climate, and how your skin feels.
Every-other-day showers work just fine for lots of people, especially if you haven’t been sweating much or getting dirty. There’s no universal rule that says you have to shower daily.
You can wash areas like your armpits, groin, and feet between showers if they need it. If you exercise, work up a sweat, or feel grimy, you may want to shower sooner; if frequent showers dry out your skin, spacing them out can help.
