Do you believe that you are watching too much TV? You might want to read this as researchers advise it will affect you later in life. A new study, reveals that people who watch television while young might lead to cognitive damage in their mid-life. It that followed more 3000 people aged between 18 to 30 years old and tracked them for 25 years.
Adults that reported to have watched TV more than 3 hours per day and exercised less failed cognitive function tests in their 50’s. Scientist were using three types of tests to check mental processing speed, executive function and verbal memory. People with low scores on these tests were linked to poor cognitive function.
The test for verbal memory however did not proved to be linked with watching television, but more with the natural aging process. For instance, it cannot be related to Alzheimer’s disease.
Although cannot be proved that low physical activity caused the slow thinking process, older studies showed that the increase of physical activity led to the improvement of thinking skills. Researchers also shown that high activity leads to increased blood flow and helps the brain.
The study was conducted by Tina Hoang of the Northern California Veterans Affairs Medical Center, San Francisco and Kristine Yaffe of the University of California, San Francisco.
A researcher that did not participated in the study found some flaws regarding it. He stated that the cognitive function of the subjects was not measured at the beginning of the study and it could not have been the base for comparison. He also found problematic the time reported for watching TV.
Other low point of the study is that the quality of what exactly people watched on TV wasn’t analyzed. Some content might have proven to be harmful than other. Present day, reading a book or engaging in an online game might be more beneficial for your health.
The study measured every 5 years the time the subjects spent on watching television. Scientist also measures every 2 to 5 years how much they exercised and showed the decline of brain powers as time passed by.
This study gives us good news as we can help our brain by putting aside the remote and getting more exercise instead.
