Logging out and taking a walk


Americans are sitting more than ever, and computers are to blame, says a new study.

The National Center for Health Statistics reports that average American adults spend about 6 1/2 hours a day sitting. That’s an hour a day more than they did a dozen years ago. Teenagers are even more immobile, sitting 8 hours a day, the study says.

Based on 16 years of data, the report, published in the Journal of the American Medical Association, makes clear that television isn’t the growing part of the problem. While about 60% of people spend 2 hours a day or more watching TV, that percentage has remained basically unchanged over the years.

What has changed is computer usage. In 2003, fewer than 30% of adults spent more than an hour of personal time daily in front of a computer; today, more than half do.

Experts note that lack of physical activity can usher in a range of health problems including obesity, diabetes and heart disease. So close that cat video, and go for a walk.
