Since most culture has been subverted by capitalism, media has become exploitative to a fault. Most media made today, wether it's film, music, video games, etc, are assembled by committee to figure out how to exploit your baser senses, your impulses.
When being submerged in this exploitative media over a longer period of time, much like doom scrolling, your brain has gotten used to the incentives your brain produces, creating a habitual cycle. It's also important to note that if you have to use your brain, most likely the media is not exploitative enough, which is why Hollywood produces mindless schlock - because it makes you feel good.
So your choice is either
Abandon all media, for a longer period of time and return sparingly (detox), or
Winding down the media consumption and only choosing ethical media (decrease dosage incrementally).
