A Harvard Medical School study of freight workers found a link between healthy eating and sleeping better. 

Adequate sleep was associated with better dietary habits, according to the study published in the November issue of American Journal of Public Health.

Study participants were over-the-road truckers, pickup and delivery truck drivers, dock workers or were employed as both truck drivers and dockworkers. They worked at eight trucking terminals in Pennsylvania, Maryland, North Carolina and New Jersey.

Researchers concluded workplace health programs should be responsive to workers’ sleep patterns. They also noted a U.S. Department of Transportation survey indicating 90 percent of truck drivers are at least overweight and 50 percent are obese.
