A new study from Montreal's public health department has revealed a concerning increase in the amount of time adults in the city spend glued to their screens during their leisure hours. The data, which compares habits from 2018 to 2025, serves as a stark reminder that the challenges of digital overuse extend far beyond children and teenagers.
Sharp Rise in Intensive Screen Use
The survey uncovered a seven-per-cent increase in the "intensive use" of screens among Montreal adults. This category, defined as four or more hours of screen time per day, grew from 16% of the adult population in 2018 to 23% in 2025. Jean-François Biron, the study's author and an expert in hyperconnectivity for Montreal public health, called this one of the more surprising findings.
"We suspected there might be an increase in the population," Biron admitted. "We hoped it would be lower. … This increase is what can lead to problems." The research also noted a 13% rise in the number of people using screens for two to four hours daily.
Who Is Most Affected?
The study pinpointed specific demographics where intensive screen use is most prevalent. It is most common among young adults aged 18 to 24, at 39%, and surprisingly, among those aged 65 and older, at 30%. The habit was also linked to lower income levels and to living alone.
Biron suggested that the evolution of attention-grabbing algorithms plays a role. "The operators of these sites make money by keeping people on their applications as long as possible," he said. He also noted that screen use became a solidified habit for many during the COVID-19 pandemic, though data showed a partial decrease afterward.
Perception Versus Reality in Digital Habits
Interestingly, public perception of screen time's impact does not always align with the amount of use. The study found that 44% of respondents believe their digital habits have a positive impact on their lives, compared to only 18% who report negative impacts. Those living alone and seniors were more likely to cite benefits.
"In other words, some people feel their digital habits are harmful even if they don’t spend much time on screens," Biron explained. This disconnect is crucial for public health strategies. Biron advocates for a harm-reduction approach, helping people take small steps rather than demanding drastic changes that could trigger resistance.
Call for Action and Alternatives
The study, designed by Montreal public health and Concordia University and conducted among 4,002 adults in early 2025, is intended to support community efforts. Biron emphasizes that addressing the issue requires a multi-faceted strategy.
"It is truly a challenge that calls on everyone to do their part," he said. Providing affordable, engaging alternatives to screens is key, especially given the link to lower income. "Offering alternatives to screens is key," Biron concluded, noting that while some cognitive screen activities can be beneficial, excessive time spent is ultimately harmful to well-being.
