For a study recently published in the journal Proceedings of the National Academy of Sciences, researchers decided to investigate the relationship between sedentary activity and dementia. In particular, they looked at both television viewing and computer use, as well as their relationship with the occurrence of general dementia.

Bad news? Increased television viewing was associated with higher rates of dementia. But it is quite interesting that an increase in the use of the computer was actually observed reduction indicators of dementia. This relationship was observed regardless of the level of physical activity.

It is important to note that this study was conducted on British biobank participants, and the authors noted that the study group lacked diversity in terms of race and ethnicity. They also note that the study relied on self-reported behavior, which can always lead to biased data.

There is no evidence that moderate TV viewing is associated with dementia risk. But while the study found compelling data about general TV viewership trends, it doesn’t offer a magic number of TV series that should be safe for cognitive health.
