Coffee can prevent depression
Women who drank two to three cups of coffee a day were 15 percent less likely to get depressed, and those who drank four cups had a 20 percent lower risk, according to a 2011 report in the Archives of Internal Medicine.
coffee can increase memory
Coffee can help improve memory, be it long-term memory or short. In a 2005 study presented at the Radiological Society of North America, researchers found that consuming two cups of caffeinated coffee increased short-term memory and reaction speed.
More interestingly, a 2007 study found that women aged 65 or over who regularly drank 3 or more cups of coffee a day had better performance in memory tests and were less likely to show memory decline than those who drank only one cup a day.
