My answer is simply to ignore the science. Unless the experimenters have done a robust randomised clinical trial (or equivalent) the conclusions are no better than an editorial. Social media is confounded by human social factors: factors which are hard to measure, poorly understood, and every bit as complex as cell signalling pathways. Never forget that scientists are under strong pressures to present results favourable to them getting future funding. This works out in the wash, but individual studies are inevitably biased. I think what we can establish is that social media has some negative and positive effects but its hard to know if social media is just a conduit or if it is the root cause. You may as well look to personal experience; if you have a bad time on social media then stop using it. If it helps you build community and joy, keep using it.
