“However，it’s too soon to advise people to hit the beach to improve health，” Wheeler said.“The study only found an association，not a cause­effect link，and it’s possible that other factors could explain the results.For instance，it could be that people who are wealthier，and therefore healthier，are more able to move to desired locations such as the coast，” Wheeler said，“a phenomenon known as the migrant effect.” But the study did find that the association between coastal living and better health was strongest for those living in the poorest areas，which perhaps indicates that wealth cannot explain the results.

　　Because the study looked at only England—an island country in which everyone lives within 72 miles of the coast—it’s not clear whether the findings would apply to other populations.Far from England，a health expert not involved in the study said that while the British research certainly doesn’t prove that people’s health and the place they live are linked，it’s possible that proximity to the seas does something for our bodies.
