Checking the news throughout the day, in scattered moments between other tasks, tends to produce more anxiety than checking it once or twice with intention. The constant low-level exposure keeps a person's attention tethered to whatever is most alarming at any given moment, without ever allowing enough space to process it properly.
Scheduling news intake means choosing a window, perhaps once in the morning and once in the evening, and treating the rest of the day as protected from it. This is not about avoidance, since the same stories still get read, but about controlling when they are read rather than letting notifications control it.
The habit takes some discipline to build, particularly around resisting the urge to check during idle moments, but most people who try it report feeling just as informed with noticeably less background unease, since a story read with full attention tends to land more usefully than one skimmed six times.
