Stress Can Shrink Your Brain

There's been a lot of research about stress and here's the bad news: it's really bad for your body and your brain. Dr. Rajita Sinha imaged the brains of 100 participants and found that profoundly stressful events (not the normal, day-to-day kinds of stress) can actually shrink the part of your brain called the prefrontal cortex.

In addition, she and her team found that it’s not individual traumatic events that have the most impact, but the cumulative effect of a lifetime’s worth of stress that might cause the most dramatic changes in brain volume.

That area of the brain helps manage our emotions, impulse control, and personal interactions. Smaller brain volumes in these centers have also been linked to depression and other mood disorders such as anxiety.

Dr. Sinha said, “The brain is plastic, and there are ways to bring back and perhaps reverse some of the effects of stress and rescue the brain somewhat.” Relieving stress through exercise or meditation is an important way to diffuse some of the potentially harmful effects it can have on the brain. Maintaining strong social and emotional relationships can also help, to provide perspective on events of experiences that may be too overwhelming to handle on your own.

So, these overstressed individuals may not be able to "just get over it." They may need large amounts of love, patience, and prayer from their church community.
