The Dhaka Times Desk A study has indicated that watching television for at least 3.5 hours per day can lead to memory loss in the elderly.
It is known that this study was conducted on 3500 adult people - who are more than 50 years old.
A 6-year study found that those who watched more TV had at least twice as much decline in verbal memory, or the part of memory that involves language, than those who watched less television. As people get older, their memory gradually weakens.
But this happens more quickly when there is too much television viewing. That's what University College London research found. However, researchers are not sure whether television is the main reason for the higher rate of memory loss.
They say that watching too much television keeps people from engaging in more brain-stimulating activities, such as reading or exercising.
According to a scientific report, those who watched television for more than 3 and a half hours a day, their verbal memory decreased from 8 percent to 10 percent.
For those who watched less television, the rate of such memory loss was only 4 percent to 5 percent. However, there was no evidence of an effect of television viewing on language fluency.
