You can overdo it, but just my personal experience is that focus on work at work, even with urgency, never brings those. Where anxiety and stress can come in for me is letting unsolvable, abstract-ish things hound me for a long time: "I have made a big mistake in life N years ago", etc. Where I think urgency is hurting is breadth: I focus only on the easiest solution and long term view goes out the window so I need to intersperse walking or similar to let my mind wander to strange, stupid or potentially good ideas. Just my 2c, YMMV.
