A study of more than 45,000 Norwegian university students has shown that using screens in bed is strongly associated with insomnia symptoms and lower sleep duration. Researchers suspect that this is because screen time displaces sleep by taking up time when people would otherwise be resting. However, using social media was not found to be more harmful than other forms of screen use.

But are people on their phone since they can't sleep? Or can't they sleep because they're on their phone?

This lol.

“Exercise makes you live longer” or, “those who are healthier are more able to exercise (and also live longer because they are healthier).”

It annoys me we still have literal scientists assuming correlation is causation without much critical thinking.

But strong findings = more citations, and more citations = more career prospects, so the system isn’t really designed to incentivise rigorousness.
