TV abuse harms your brain, here’s the proof

Spending too much time watching TV can have a very negative impact on your brain health as you get older. This is the conclusion of three newly published scientific studies.

Television can harm the brain

We like to wallow in front to watch our favorite programs. Especially since now, there are TVs as imposing as they are sophisticated since the emergence of OLED, QLED or LED TVs. Watching television, however, is not trivial for our brain health. This is the point of three new scientific studies presented this week at the Epidemiology, Prevention – Lifestyle & Cardiometabolic Health Conference 2021.

They thus reveal that people watching television (in a moderate to heavy fashion) from their forties have experienced a greater cognitive decline than people who consume little TV. It is especially when they are 70 years old that this manifests itself. Moreover, they also see the volume of their gray matter decrease. As a reminder, this part of the nervous system (located in the brain) is involved in many brain functions. Like muscle control, vision, hearing or even decision-making.

Not all sedentary activities harm the brain

The biological processes that cause dementia (such as brain breakdown) tend to start around your 40s. Is ” a period [où] modifiable behaviors, such as excessive television viewing, can be targeted and reduced to promote healthy brain aging ”, says Ryan Dougherty, lead author of one of the studies. The researchers also specify that watching television is passive behavior that involves little cognitive stimulation.

Unlike other sedentary activities like reading or playing video games. These maintain a good level of cognition while reducing the risk of dementia. However, this new research has yet to be confirmed by further studies. They did, however, take into account certain factors other than TV likely to affect the health of the brain (age, level of education, genes favoring the appearance of Alzheimer’s).

However, they did not take other factors into consideration. Namely, in particular the total sedentary time of the subject observed. It should be noted, however, that an older study published in the journal Jame Psychiatry already affirmed that too much television consumption could harm the brain as we age.
