A new study has found that people who watched television more frequently during midlife were more likely to have smaller volumes in brain regions involved in memory, learning, and decision-making decades later, adding to growing evidence that certain sedentary habits may influence long-term brain health.
While the researchers emphasized that the findings do not prove television viewing causes brain shrinkage or dementia, they suggest that prolonged passive screen time during middle age may be associated with structural brain changes that warrant further investigation. The research also highlights the potential importance of maintaining mentally stimulating activities throughout adulthood to support healthy cognitive aging.
