If you endure long commutes, "you are on your way to heart disease," Dr. Suzanne Steinbaum, a preventive cardiologist at Lenox Hill Hospital in New York City, told WebMd.com. "[When] you have an elevated blood pressure, an elevated BMI (body-mass-index), an elevated waist circumference; you're on your way to diabetes and high cholesterol," says Steinbaum. "This is a person that I say, 'Change your life now so you don't get sick later,'" Steinbaum says.
How was the study conducted? Everyone in the study took a treadmill test to measure how long and vigorously they could exercise. And researchers checked a slew of indicators for heart disease and diabetes. Those included elevated blood sugar levels, cholesterol, total fat, belly fat, and BMI -- a measure of weight in relation to height. People in the study were also asked how much and how intensely they exercised each week.
According to the researchers, the number of workers driving to work by private car more than doubled between 1960 and 2000, increasing from more than 41 million to nearly 113 million. The average distance traveled to work also has grown in recent years, from nearly nine miles in 1983 to more than 12 miles in 2001, the researchers said. That may not sound like much, but those are averages. Commuters in many cities surpass those averages by a lot.
