It's interesting that two of the six things that the author suggests negatively effect mental health are social media. I think that a better understanding of the impact of habits driven by social media will be a great step forward. Of course, they've hardly been such a pervasive force for very long, so the long-term effects could not be well understood at this point. I see this generally negative sentiment increasingly often, though, and I definitely think there's a lot of truth to it.
