You can endlessly debate whether city or country life is better. But research has found that people living in urban settings do have a 39% higher risk of mood disorders than those in rural regions. A 2011 study in the journal Nature offers an explanation for this trend: City dwellers have more activity in the part of the brain that regulates stress.
