9. Coffee Can Fight Depression and Make You Happier
Depression is a serious mental disorder that causes a significantly reduced quality of life. It is incredibly common and about 4.1% of people in the U.S. currently meet the criteria for clinical depression. In a Harvard study published in 2011, women who drank 4 or more cups per day had a 20% lower risk of becoming depressed. Another study with 208,424 individuals found that those who drank 4 or more cups per day were 53% less likely to commit suicide.
Bottom Line: Coffee appears to lower the risk of developing depression and may dramatically reduce the risk of suicide.
