So many of our patients tell us they depend on their coffee each day. That got us thinking about any link between coffee consumption and depression, or prevention thereof. A recent study found that women who drink four cups of coffee a day are 20% less likely to become depressed, compared to women who drink no coffee. The researchers looked at over 50,000 women, with an average age of near 60. None of the women were depressed when they entered the study. The researchers also tried to control for other factors that can lead to depression, such as smoking or a couch type, sedentary lifestyle.
These results are pretty impressive. While we cannot say that coffee consumption causally helps prevent depression, it makes us stop for a moment, and think about what may be occurring here. Perhaps there are certain areas of the brain that are linked to depression that are affected by caffeine consumption. Until more research occurs though, this study will definitely help us (and maybe you) enjoy our morning coffee just a little bit more!
