Study: How much TV watching affects the brain

Bad news for fans of TV evenings and series addicts. A study by Ryan Dougherty of the Johns Hopkins Bloomberg School of Public Health in Baltimore found that watching TV is bad for the brain.

Excessive television viewing has long had a reputation for being harmful to health. So far, however, there have been few studies on this. The Bloomberg School has now studied 599 middle-aged people for eleven years for their TV viewing and brain activity.

Brain shrinks

Conclusion: The gray matter in the brain, which is responsible for the motor skills of the skeletal muscles and for the sensitivity of the nerve cells, decreased the more the test person sat in front of the television. The frontal lobe and the entorhinal area also became smaller.

So the brain shrank from a lot of TV consumption. This fact can lead to diseases such as dementia and Alzheimer’s.

The study results showed that the gray matter was only reduced by 0.5 percent.

Regardless of diet or exercise

According to the authors of the study, the brain shrinking took place regardless of the level of exercise or diet. On average, the subjects watched two and a half hours of TV every day.

“Our data suggest that TV consumption – regardless of physical activity – plays a role in brain and body health,” explains study leader Ryan Dougherty

It is not clear whether there are differences in TV content such as documentaries that are received. The study only speaks of TV consumption in a very general way.
