Don't passively accept and engage to any content that appears in front of your eyes. Think first what about you want to read, then look actively for that information.
Don't infinitely scroll down the news feeds. Don't do it at all.
Don't read news that don't matter in your life.
Before start reading some article, regardless of how catchy and interesting title might be, ask yourself: Do I need to read/watch/listen to this now? Do I need this information now? How will I benefit from this content?
Information filtering is the key! Automate this by passing this task to some AI-based PA. Define rules about which information/news matter to you.
Finally, be content creator, not (only) content consumer.
