“While this study can't prove sleep duration is causing these infections, the team says it underlines how important sleep is to keep us healthy.” No, that’s not how causation works. This article didn’t prove causation, only correlation. The actual problem could be something completely different with the sleep issues as a symptom. Why does it seem like the bar is continually dropping in peer review?

I think the point is if you're consistently sleeping too much or too little it's likely (or always) caused by other factors that need to be dealt with. Work, health, etc.

Studies like this often suggest that simply forcing oneself to sleep more or less will just make things better all by itself. Without knowing the cause, this could even make things worse.

Edit: For example, some health conditions (like allergies) constantly exhaust the body and result in needing extended rest to recover. Not allowing yourself that rest, without dealing with the condition itself, will just make it worse.

Yeah but (for example) depression is also sickness. Depressed people sleep more, and also get ill more often because of weakened immune system they tend to have. But I have never heard any evidence that it is too much sleep that causes this. Or can it be a chicken-egg problem
