How Does Traffic Affect Our Health?

Like many of you, I dislike driving in heavy traffic. But unlike many of you, I usually don’t have to. I live and work in California’s Santa Cruz Mountains, and my job is just steps from my home. Driving in the mountains can be challenging, but that’s mostly because of twists and turns in the roads, not traffic.  For occasional business meetings and appointments, I venture down into Silicon Valley and even into San Francisco. As I crawl through town after congested town, or sit bumper-to-bumper on traffic-jammed highways, I’m always struck with how lucky I am that I don’t have to deal with this daily grind. I’m also filled with compassion for all of you who do.

Fortunately, there are tools that can help make your morning and evening commutes considerably easier – on your mental, emotional and physical health.

The Tolls of Traffic

On a recent weekday morning, a list of travel advisories for metropolitan areas around the country popped up on my kitchen television.

  • Washington, D.C.: Expect delays. Allow 3 hours.
  • Los Angeles-Long Beach-Santa Ana: Expect delays. Allow 2.5 hours.
  • Dallas-Fort Worth-Arlington: Expect delays. Allow 2 hours.

With light traffic, the typical commute in most urban areas would take about a half-hour. But, as you well know, light traffic happens mostly in the dead of night, not during the morning rush hour.

In 2011, we Americans whiled away 5.5 billion hours of our time, burned through 2.9 billion gallons of fuel, and shelled out $121 billion of our hard-earned money driving in stop-and-go traffic on our nation’s highways. These stunning figures appear in the 2012 Urban Mobility Report of the Texas Transportation Institute at Texas A&M University.

Today the high dollar cost of traffic congestion can be quantified, thanks to GPS-enabled vehicles that collect data nationwide. But what about the mental, emotional and physical tolls on all of us who collectively spend those 5.5 billion extra hours a year behind the wheel?  Although quantitative data on the costs to our health and well-being is less plentiful than data on the costs to our pocketbook, what is available shows that we are paying a very high personal price as well.  Traffic dwellers are more prone to stress, distraction, aggressive behavior, elevated blood pressure and larger waistlines, says one study released last year.

Heart-Traffic Connection

Even more alarming news came from the American Heart Association. A study has found a link between traffic and heart attacks. “People who have had a heart attAngry man stuck in trafficack are likely to report having been in traffic shortly before their symptoms began,” stated a release from the Heart Association’s 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. The association cited a German study that identified simple exposure to traffic as the key contributing factor in heart attacks. “Driving a car was the most common source of traffic exposure, but taking public transportation or riding a bicycle were other forms of exposure to traffic,” the association reported. “Overall, time spent in any mode of transportation in traffic was associated with a 3.2 times higher risk [of heart attack] than time spent away from this trigger.”

The Texas Transportation Institute found that an automobile commuter in Washington, D.C., spent an average of 67 hours in traffic each year. That’s about one and a half traditional work weeks! Commuters in the San Francisco-Oakland and the Los Angeles areas spent 61 hours each; those in the New York City area, 59 hours.

People who drive in large urban areas aren’t the only ones with traffic travails.  “Congestion is worse [than the previous year’s findings] in areas of every size,” the institute’s report said. “Big towns and small cities alike cannot implement enough projects, programs and policies to meet the demands of growing population and jobs.”

Interesting...makes me grateful to live in a rural area...where one might be delayed by escapee cows in the dark, goslings crossing a rural dirt road...and how many pot holes to avoid.

Like anything else that challenges us ... we have a choice in how to react ......" Why, why me, whine, whine, whine" OR "Thank God for a car" ... "that I survived" ... etc"

The treatment for the symptoms are great. Now, we must find the cause or causes of the disease (heavy traffic) that create the symptoms and eliminate them. Then, we will have a cure

Tomorrow I'm going to have to be in a car for nearly an hour. And it won't even be to go somewhere fun. :(
