New research from a group of Canadian universities suggests a strong correlation between access to urban green spaces and reduced stress levels. The multi-year study, conducted in Toronto, Vancouver, and Halifax, examined how proximity to parks and natural environments affects mental wellbeing.

Researchers tracked the daily routines, cortisol levels, and survey responses of over 3,000 participants from a wide range of socioeconomic backgrounds. The results showed that individuals living within a 10-minute walk of green space consistently reported lower stress and better mood regulation.

Lead researcher Dr. Tanisha Roy from the University of Toronto said the findings reinforce the importance of preserving and investing in green infrastructure. “Urban parks are not just amenities—they’re essential components of a healthy city,” she noted.

The study found that even brief visits to green spaces—such as a 15-minute walk through a tree-lined park—were associated with measurable physiological benefits, including lower blood pressure and reduced stress hormone levels.

Interestingly, the effects were more pronounced in lower-income neighborhoods, where green space often serves as a vital refuge from urban density and environmental noise. This highlights the role of equitable access in public health outcomes.

In addition to quantitative data, researchers conducted in-depth interviews with participants. Many described green spaces as places of healing, reflection, and social connection. One respondent called her neighborhood park “a sanctuary in the middle of the city.”

The study also examined the quality of green space, not just proximity. Parks with maintained trails, shaded areas, and biodiversity had a greater positive impact compared to smaller or poorly maintained lots.

Policy experts are already taking note. Toronto city planners say the findings support the city’s Parkland Strategy, which aims to expand green coverage in underserved areas and improve maintenance standards across the board.

Environmental groups have echoed these calls, advocating for more investment in urban forests, rooftop gardens, and community green spaces. They argue that these spaces offer not only environmental benefits but also act as frontline mental health interventions.

As climate change continues to shape urban planning conversations, the psychological dimension of green space is gaining attention. Researchers say mental health should be considered alongside carbon offsets and biodiversity in environmental assessments.

The study's authors plan to publish follow-up research examining how seasonal changes affect the stress-reducing impact of green space, as well as whether virtual nature experiences can replicate the benefits of physical exposure.

With mental health challenges on the rise in Canadian cities, this research underscores a simple yet powerful message: nature heals. The implications for urban design, public policy, and healthcare are significant—and timely.
