For the past few months, since my sister started medical school, I have been hearing a lot about what compounds from vitamins your brain and body need to function at its peak. This article mentions vitamin D deficiencies as one of the possible causes of depression, and shows some pretty scary statistics about the correlation between the two. In a recent study of individuals with depression and anxiety, recovering from depression, or otherwise healthy individuals, 33% had insufficient levels of vitamin D, and the lowest levels were found in a individuals with the most severe depression. These are pretty high numbers, so getting levels tested is recommended for anyone who is depressed, which I think is a good idea. The other factors mentioned in the article are tips you hear often, but that doesn’t make them any less important. These are things like a social support system, physical activity, and being optimistic and more reasonable with your expectations with yourself. If you explain things that happen in your life pessimistically it starts to form a cycle where it can make your more depressed, and then more likely to again explain things pessimistically. Another way to break out of this cycle that goes along with social support is having discussions that stimulate your mind that are more cognitively challenging, which if lacking can make you feel like you are stuck in a rut. Even though some of these tips are well known by most people, the tips such as getting vitamin D levels tested, are something to consider if you haven’t been able to make any progress in your depression just to understand yourself better.
