A simple daily adjustment – reducing television viewing time – may significantly lower the risk of developing major depressive disorder, according to a new study published in European Psychiatry. The research, which tracked over 65,000 adults for four years, suggests that even an hour less of daily screen time can have a measurable impact on mental well-being, particularly for individuals in their 40s.
Depression is a growing public health concern. According to a 2024 report from Santé publique France, 15.6% of French adults aged 18 to 79 experienced a major depressive episode in the past year, with rates climbing to around 22% among those aged 18 to 29. Understanding modifiable lifestyle factors, like time spent watching television, is crucial for preventative strategies. This new research offers a readily accessible intervention for reducing depression risk.
The Link Between Screen Time and Depression
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 from depression. The study meticulously tracked participants over a four-year period, examining the correlation between television viewing habits and the onset of depressive symptoms. The findings revealed a clear association: reducing time spent in front of the television and dedicating that time to other activities lowered the probability of developing major depression.
“We found that reducing television viewing time by 60 minutes and dedicating it 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%.”
Midlife Benefits and the Power of Physical Activity
The protective effect of reducing screen time was most pronounced among individuals in their 40s. Replacing just one hour of daily television viewing with other activities resulted in an 18.78% reduction in depression risk within this age group. Increasing the reduction to 90 minutes lowered the risk by 29%, and eliminating two hours of daily television viewing was associated with a substantial 43% decrease in risk.
While beneficial across all age groups, the study found that older adults and young adults experienced less benefit from simply reducing screen time. For seniors, engaging in physical activity alongside reducing television viewing was essential to observe a measurable difference. “Replacing 30 minutes of television with sport 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 researchers noted.
Beyond the Couch: What Activities Offer the Most Protection?
The study demonstrated that almost any activity replacing television viewing was associated with a reduction in depression risk, 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. Dedicate the 30 minutes saved from reduced screen time to exercise, and the risk of depression decreased by 18% across all age groups. Sleep followed, with a 9% reduction in risk, while leisure activities and commuting contributed to an 8% decrease. On average, French adults spent approximately 4 hours and 14 minutes per day watching television in 2025, encompassing live broadcasts, replays, and on-demand video, according to Advanced Television, highlighting the potential for significant mental health gains through mindful screen time reduction.
This research underscores the importance of prioritizing activities that promote both physical and mental well-being. While the convenience of television is undeniable, making a conscious effort to incorporate more movement, social interaction, and restorative sleep into daily routines can have a profound impact on reducing the risk of depression.

Researchers will continue to investigate the underlying mechanisms linking screen time and mental health, with future studies planned to explore the role of social connection and specific types of physical activity. The next phase of the Lifelines cohort study will focus on identifying personalized interventions for individuals at high risk of depression.
