First have a better idea of what you want to get out of reading. Entertainment: fictions. Knowledge: non-fictions. Current event update: news. Social discussions: social media (e.g. LW, Reddit, Facebook, etc.). Once you know what you are looking for exactly, or what kind of experience you are looking for, then you don't end up wasting your time on doing things that you don't consider productive.
When you take a break, I assume you just want some bite-sized, easily digestible content. News aren't really good with that stuff since it's mostly repetitive and mostly inconsequential in your own daily life.
A fun thing to do is to come up with questions yourself. What do you really want to learn about? What are you interested in finding out? Then come up with an approach to answering those questions for yourself or at least a guideline for how you want to look for information. This will make your break from work reading more fulfilling.
Before the internet, people are pretty much limited to whatever is available in their local libraries and more. With internet, we are still only looking around places that are more easily accessible, but other sources and sites are only a few clicks and searches away.
Mindless indulgence is never as satisfying as mindful indulgence, but there is nothing wrong with mindless indulgence if you don't really have anything to look for. It's more about how many years you've spent mindlessly wandering around as opposed to whether you are actively researching something at the present, which essentially may lead to questions like yours/this because of existential dissatisfaction.
