subject: America's Top 10 Healthiest Cities [print this page] Orange County, CA is known for its sprawling beaches, never-ending sun and laid-back attitude. Perhaps, that is why Orange County made the top of the list for America's least stressful cities. Locals enjoy healthy food much of which is grown locally in California, and an environment perfect for surfing and swimming. Halfway between San Diego and Los Angeles, residents also can take advantage of the healthy attractions in those nearby cities. Although traffic and lots of driving can be a negative, many residents just kick back and let the waves "wash off" their stress.
