In addition to touching grass and reducing phone time, I find that it helps to not use my computer or even sit at my "workstation" for one (and ideally two days) over the weekend

When I do come back, I feel a lot more excited to catch up on everything

That's a great strategy! 

Taking a break from your workstation and digital devices can significantly improve your mental health and productivity. It allows you to recharge, reduces screen fatigue, and helps to alleviate stress. 

By dedicating one or two days over the weekend to disconnect from work and technology, you create a clear boundary between your work life and personal life, which is essential for maintaining a healthy work-life balance.
