A commute of 10 miles or longer was associated with an increase in high blood pressure, and a drive to work of more than 15 miles was associated with a greater susceptibility to obesity, according to research published in the American Journal of Preventive Medicine. Another study of more than 34,000 workers for a partnership of the University of Cambridge, RAND Europe and Mercer, found that people with long commutes are 33 percent more likely to suffer from depression, 12 percent more likely to report work-related stress, and 21 percent more likely to be obese.
