Watching TV and life expectancy

A new study has found that every hour of watching TV may decrease your life span by 22 minutes. But is watching TV really the problem? Or is it how we watch TV? That’s a question that hasn’t been definitively answered.

When we watch TV, we’re typically sitting or lying down, our bodies at rest, often for long periods of time. We also tend to eat while we watch, frequently snacking on unhealthy foods. Studies have shown a direct relationship between inactivity and life expectancy, but in the case of TV viewing, there is a question of correlation vs. causation.

Suggesting we all unplug our TVs for good would be an extreme reaction to the research–and an unrealistic one at that. The study does serve as a wake-up call, however, about how our habits and the ways we choose to spend our time may affect our health. Or maybe it’s time to start looking at our favorite shows differently.
