Study claims drinking lots of coffee could be making you 'dumber'

Most of us start our day with a cup of coffee, thinking it will give us an energy boost for a successful and productive day.

But according to new research that morning coffee might not be stimulating our brain in the right way.

Best Mattress Brand conducted a study of over 1,000 university students and found that those who drank more coffee had lower grade point averages (GPAs)...

So what is it about coffee that causes us to become 'dumber'?

It all comes down to the fact that coffee keeps us awake.

You see, a lack of sleep affects a person’s ability to form long-term memories.

Students who drank two or more cups of coffee daily were averaging five to six hours of sleep every night - which is well below the eight hour recommendation.
