Study warns TV harms brain health
A American study has shown that excessive television viewing during mid-life can harm brain health and lead to changes in areas related to memory and cognitive functions, increasing the likelihood of developing dementia after about 20 years. Researchers followed the condition of approximately 1,700 individuals, with an average age of around 53, over two decades. They found that those who watch television excessively tend to experience a reduction in the size of important brain regions such as those associated with memory and attention. Conversely, people who work for extended periods show an increase in the size of the frontal and parietal lobes, which are linked to cognitive functions and attention. The researchers advise not to overdo sitting in front of the TV and to follow expert recommendations to make the best use of free time and protect brain health.
