Brandon Keim reports for Wired:
Between the crowds and the noise and the pressure, city life often seems to set one’s brain on edge. Turns out that could literally be true.
A study of German college students suggests that urbanite brains are more susceptible to stress, particularly social stress, than those of country dwellers. The findings don’t indicate which aspects of city life had changed the students’ brains, but provide a framework for future investigations.
“Whether people are exposed to noise, live near a park, have a big group of friends or not — you can do those experiments, and tease apart which parts of urban living are associated with these changes,” said Andreas Meyer-Lindenberg, a psychiatrist at German’s Central Institute of Mental Health.
Meyer-Lindenberg’s findings, published June 23 in Nature, are a neurological investigation into the underpinnings of a disturbing social trend: As a rule, city life seems to generate mental illness.
Compared to their rural counterparts, city dwellers have higher levels of anxiety and mood disorders. The schizophrenia risk of people raised in cities is almost double. Literature on the effect is so thorough that researchers say it’s not just correlation, as might be expected if anxious people preferred to live in cities. Neither is it a result of heredity. It’s a cause-and-effect relationship between environment and mind.
