[ELI5] – Why is standing is more exhausting?

Question

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?

because you’re using your muscles to keep your body upright and balanced. you might not notice it, but fatigue does accumulate over time.
