Such were the findings of University of Bristol researchers published in the latest issue of Neuroscience.
According to the paper's lead author, Dr. Chris Lowry:
"These studies help us understand how the body communicates with the brain and why a healthy immune system is important for maintaining mental health. They also leave us wondering if we shouldn't all be spending more time playing in the dirt."
