Passage Three

Watching more than 3 hours of television a day doubles memory loss in older people, a new study of more than 3,000 adults suggests. Scientist at University College London used memory and fluency tests on the same group of people 6 years apart. They found that those who watched on average less than 3 hours television a day showed a decline ever round 4 to 5 percent, while those who tended to watch more than 3 hours a day declined by an average of 8 to 10 percent. The research team say they believe the alert but passive nature of television watching maybe creating stress on the mind, which contributes to memory decline.

Older people who watch more television are also less likely to undertake activities knowing to preserve mental functioning, such as reading or interactive screen base pursuits, such as using the internet or playing video games. The researchers say that television viewing maybe a risk factor for all Alzheimer’s disease, but more researches needed to establish a link.

While watching television may have educational benefits and relaxation benefits, the researchers advise that adults over the age of 50 should try and ensure that television viewing is balanced with other contrasting activities. If you’re concerned that the amount of television you’re watching could have a negative impact on your health, you should eliminate the amount of TV watch each day and undertake some healthy hobbies.
