Less TV, Lower Depression Risk: Study Finds 1 Hour Makes a Difference

Spending less time watching television and more time engaged in other activities may help prevent major depressive disorder, particularly during middle age, according to a new study. The findings, published in European Psychiatry, suggest a simple lifestyle adjustment – reducing daily television viewing by just one hour – can have a significant impact on mental well-being.

Depression Risk and Television Viewing: A New Link

According to data from Santé publique France in 2024, 15.6% of French adults aged 18 to 79 experienced at least one episode of characterized depression in the past 12 months. Prevalence is even higher among young adults aged 18-29, reaching around 22%. However, the recent study sheds light on a proactive step individuals can take to mitigate their risk.

Researchers, led by Rosa Palazuelos-González of the University of Groningen in the Netherlands, evaluated the lifestyle habits and mental health of 65,454 adults who were initially free of depression. Participants were followed for a period of four years.

“We found that reducing television viewing time by 60 minutes and dedicating that time to other activities moderated the probability of developing major depression by 11%,” explained Palazuelos-González in a press release. “For reallocations of 90 and 120 minutes, this decrease in probability reached 25.91%.”

Middle Age: A Critical Window for Intervention

The beneficial effects of reducing screen time were particularly pronounced in middle-aged adults. In this age group, replacing one hour of daily television with other activities lowered the risk of depression by 18.78%. Reducing television viewing by 90 minutes resulted in a 29% risk reduction, and those who eliminated two hours of daily television saw their risk plummet by 43%.

Older adults and younger adults experienced less benefit from reducing screen time. Among seniors, engaging in sports was the only activity that demonstrated a measurable difference. “Replacing 30 minutes of television with sports reduced the probability of depression from 1.01% to 0.71%. With 60 minutes, the risk fell to 0.63%, and with 90 minutes, to 0.56%,” the authors noted.

Beyond Television: What Activities Offer the Greatest Benefit?

The study revealed that nearly all activities used to replace television viewing were associated with a decreased risk of depression, with one notable exception: housework. “Replacing only 30 minutes of television with household chores did not lead to a significant change,” the researchers found.

Physical activity emerged as the most impactful alternative. Dedicating 30 minutes less to screen time to exercise reduced the risk of depression by 18%. Across all age groups studied, physical activity demonstrated the strongest reduction in the probability of developing major depression.

Sleep followed, with a 9% reduction in risk. Leisure activities and commuting also contributed to risk reduction, lowering the likelihood of depression by 8%.

On average, French individuals spent approximately 4 hours and 14 minutes per day watching television in 2025, encompassing live programming, catch-up services, and on-demand video content. This study serves as a reminder of the importance of balancing screen time with other activities to promote overall well-being.

Implications for Public Health

These findings underscore the potential for simple behavioral changes to have a substantial impact on mental health. While the study demonstrates an association between reduced television viewing and lower depression risk, it does not establish a causal relationship. Further research is needed to fully understand the mechanisms underlying this connection.

However, the results suggest that public health initiatives aimed at promoting physical activity, encouraging sufficient sleep, and reducing sedentary behavior could play a crucial role in preventing depression, particularly among middle-aged adults. The study highlights the importance of considering not just the reduction of harmful behaviors, such as excessive television viewing, but also the active replacement of that time with beneficial activities.
