A 25-year-long study recently published in JAMA Psychiatry reports that young adults who watch a lot of TV and have low physical activity may have worse cognitive function when they reach middle age.

Researchers studied 351 adults, categorizing those who watched 3 or more hours of TV per day as “high” viewers. The researchers gave each participant three cognitive tests at the end of the 25-year study that measured executive function (their ability to manage time and resources to achieve a goal) and their ability to recall information.

After adjusting for age, race, gender, education level, smoking, alcohol use and body mass index, the researchers found that participants who spent a lot of time viewing TV and who had lower physical activity levels were twice as likely to perform poorly.
