6. Boston, Massachusetts
Outsiders might think Boston is all Sully and Fitzy sipping Smithwick's over creamy clam chowder, but residents know this stereotype is off. This notoriously smart city is also super fit and prioritizes healthy eating. Even though Boston doesn't have as many community resources such as golf courses and pools as other high-ranking cities, it has plenty of parks, and is a hotspot for commuting by bike or foot and regular exercise. As a result, obesity rates are low and mental health is one of the higher on the list. Boston also boasts excellent health care facilities that most residents can actually take advantage of, thanks to almost universal healthcare in Massachusetts. Research shows that increased care access has already led to improvements in overall physical and mental well-being.
