The following is the The study said that watching TV often may make people face the risk of cognitive decline in later life recommended by recordtrend.com. And this article belongs to the classification: Life data.

According to foreign media reports, if you are a TV fan now, this habit may make you face the risk of cognitive decline in later life. That’s according to three new studies published by the American Heart Association, which found that moderate to high TV consumption in middle age is associated with lower gray matter volume and cognitive decline in old age.

The study defined middle age as 45 to 64 years old; It also classifies TV watching as sedentary behavior, a lifestyle that is often associated with a deterioration in a person’s brain health in old age. A person’s cognitive ability, such as a person’s thinking and memory ability, will naturally decline with age.

The new study assesses whether sedentary middle age accelerates cognitive decline; It is based on self-reported data on TV watching habits. The responses were divided into groups: occasionally watching TV, meaning little or never watching TV, and moderately (sometimes) and highly (often).

One of the two different studies found that moderate and frequent TV watching was associated with a 6.9% increased risk of cognitive decline over the next 15 years. However, regular TV watching is not associated with an increased risk of dementia.

The second study, which included MRI brain scan data, linked moderate and frequent television viewing to a decrease in deep gray matter volume more than a decade later. Compared with those who seldom watch TV, the impact of those who have been reporting moderate and regular TV watching for many years is particularly obvious.

However, the link between the habit of watching TV and later brain health is not just due to the sedentary nature of TV. The researchers pointed out that other sedentary activities that stimulate the brain – such as playing board games – are not associated with a greater risk of dementia.

Dr. Ryan Dougherty, the lead author of one of the studies, explained:

In terms of cognition and brain health, not all sedentary behaviors are equal; Non stimulating sedentary activities, such as watching TV, are associated with a greater risk of developing cognitive impairment, while cognitive stimulating sedentary activities, such as reading, computer and board games, are associated with maintaining cognition and reducing the likelihood of dementia. When investigating cognitive and brain health, it is important to consider the background differences of different sedentary behaviors.
