WASHINGTON (CBSDC) — Drivers in the Washington region face some of toughest commutes in country. As it turns out, the “killer” daily pilgrimage to the office could, in fact, kill you.

A new study in the American Journal of Preventive Medicine shows people who commute 16 or more miles to the office each day, in each direction, are at an increased risk for obesity and high blood pressure.

“Doing that five days per week and 48 to 50 weeks out of the year certainly takes a toll,” Dr. Steven Marshak told All-News 99.1 reporter John Domen.

In addition to the increased body size, the commuter will also struggle with fatigue, irritability and stress according to the study.

Doctors say that it is imperative for marathon commuters to make time to exercise each day. Even a 30-minute workout three times per week can help offset the ill effects of prolonged time in the car.

Also key? Getting plenty of sleep and eating breakfast.
