I wonder how much news related issues have to do with the way news is presented rather than the frequency at which you read the news. Daily news reading doesn't strike me as concerning given that getting a newspaper delivered in the mail in the morning was entirely normal practice and people didn't seem to experience the distress they do now. Between the 20s and up until the 70s almost every American household subscribed to a daily newspaper.
I figure the fact that news has turned into hedonic consumption is the much bigger deal. Neil Postman wrote a book, Amusing Ourselves to Death outlining how mass media turned all programming into entertainment programming. Everything is stimulating, emotionally charged etc. That to me seems to be the exhausting part.
So as for the title of this publication people really seem to be into the "delayed" part but I think the "gratification" part might be the problem
