From the Austin American-Statesman:
Besides taking time away from family, a long commute can be harmful to your health. Researchers have found that hours spent behind the wheel raise blood pressure and cause workers to get sick and stay home more often. Commuters have lower thresholds for frustration at work, suffer more headaches and chest pains, and more often display negative moods at home in the evenings.
“You tell someone they need to exercise or go to physical therapy, but how can they? They leave at 5 a.m. and get home at 7 or 8 p.m. at night,” said Robert Squillante, an orthopedic surgeon in Fredericksburg, Va., who has treated patients for back pain and other commuting-related problems.
Constant road vibrations and sitting in the same position for a long time are bad for the neck and spine, he said, and put special pressure on the bottom disc in the lower back, the one most likely to deteriorate over the years.
