[ELI5] – Why is standing is more exhausting?

138 views

I was proctoring a classroom today and I was standing, and although I wasn’t doing anything but standing, I felt that I kept getting more tired.

Why do we get tired even though we do nothing but standing still?

You don’t feel you’re doing anything but your muscles are working to hold you upright, especially your core.
