Turns out that religion and spirituality are good for the brain! A strong connection to spirituality actually makes the brain tissue itself stronger.
For years, psychiatrists have known that religion and spirituality protect against depression. Studies have shown up to a 90% decreased risk of depression in people who had a strong religious or spiritual connection.
A study published in the American Journal of Psychiatry in 2011 showed that having strong religious or spiritual beliefs prevented a recurrence of depression. In this study, led by Lisa Miller, Ph.D., an associate professor of psychology and education at Columbia University Teachers College, assessed the influence that a strong connection to religion or spirituality had on the mental health of 114 adult children of both depressed parents and non-depressed parents. The study found that those who reported a high personal attachment to religion or spirituality had only a one fourth risk of experiencing depression as those who did not.
Religion and spirituality also protected those with a family history of depression. For people whose parents had depression, a strong attachment to religion or spirituality reduced their risk of experiencing depression to just one tenth.
It turns out that a connection to religion or spirituality actually affects brain tissue.
In a new study, published in JAMA Psychiatry, a strong attachment with religion or spirituality was associated with thicker cortices in multiple brain regions. Thicker brain cortices are associated with decreased risk of developing depression. Depression has been found to cause the brain cortices to thin. The theory is that if they are thicker to begin with, they are less likely to thin to a level that causes depression.
You don’t need organized religion. The same studies showed no correlation between frequency of attendance and protection against depression. Nor did they find any particular denomination offered increased protection. In other words, it was the connection to spirituality or religion that offered protection rather than level of participation in an organized religion. What this means for you is that to protect yourself against depression, you just have to find your own spiritual path. So pray your depression away in whatever manner suits you. Your brain will thank you.
