The article does not mention if they actually showed causality. What if there is a third variable (coffee, acquired virus, anxiety, lack of exercise) that simultaneously causes lack of sleep and a depressed immune system? The cause could even be the other way around - I know I don't sleep well when I'm feeling sick.

Even without knowing the underlying reasons behind the issue, you can at least diagnose based on the easily visible corrleated event----sleep depravation is much easier to test for than the comorbid immune supression.
