Bad News For Bingers: Watching Too Much TV Linked to Smaller Brain Volume

A long-term study of more than 1,700 adults linked frequent TV watching in midlife to smaller brain volumes and more white matter damage later in life.

The effect was especially strong in men, suggesting gender differences in how sedentary habits may affect the brain.

By contrast, sitting at work was associated with healthier brain measures, showing that not all sitting has the same impact.

Researchers say prolonged TV viewing may be a modifiable risk factor for later cognitive decline and dementia.
