does caffeine cause brain fog?

There's been some speculation that caffeine may be linked to brain fog. But is there any truth to this claim?

There's no definitive answer to this question. Some people say that caffeine makes them feel foggy, while others don't notice any impact.

However, there is some evidence that caffeine can cause issues with focus and concentration. For example, a study published in the journal "Psychopharmacology" found that caffeine can impair task performance in people who are not used to it.

If you're concerned about potential negative effects of caffeine on your brain function, it might be a good idea to limit your intake or try switching to decaf for a while.
