A coffee hit might be more commonly associated with increased alertness, but a new study shows that it could also help lower the risks of developing anxiety and depression – and there's actually a sweet spot when it comes to how much to drink to get the best effect.
Usually, yes, but where coffee is concerned (labeling on coffee makers, for example) a “cup” is traditionally 3/4 of that.
So it’s ambiguous if they don’t specify further. (Do they? The link isn’t loading for me.)
236ml in the US because it makes no sense.
No, they only surveyed using the word “cup” , another typical shit epidemiology study.
People use caffeine to self medicate, cause and effect are therefore impossible to determine.
