The study found higher cortisol levels following stress in people who had lower water intake. It seems like a poorly-designed study jumping to news-headline-worthy conclusions, but for anyone who thinks that their ME symptoms are related to cortisol levels, altering water intake seems like simple, safe experiment.
I think there are plenty of other explanations for their experimental findings that don't show a correlation between water intake and blood cortisol levels (they measured saliva levels).
