TV or computer use and brain health
A new study suggests that the pattern of activity while sitting significantly impacts brain health and reduces the risk of cognitive decline. In particular, excessive television watching is associated with increased white matter damage and a decreased size of brain regions most vulnerable to aging and Alzheimer's disease. Conversely, sitting while working on a computer or engaging in activities that require continuous mental engagement is linked to less harm and may help preserve cognitive health. Watching TV is considered a passive activity that reduces mental stimulation and is associated with unhealthy behaviors such as prolonged sitting and snacking. The study's results indicate that the nature of seated activities matters; activities that involve thinking and analysis, such as office work, may help lower the risk of cognitive decline. Additionally, social interactions linked to activities like going to the cinema may bolster brain protection against dementia.
