Keeping the balance between work and relaxation

On some days, it's really difficult for me to keep a good balance between work and relaxation. Most of the time, it's that urge to "be productive" and spend my time on something important.

If I think about it rationally, I know it's just healthy and needed to take breaks, but emotionally it feels like "giving up" for that day. Just wanted to ask if there are other people having a hard time letting go of work for a full day.
