Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Increasing time in nature, Nature-based interventions, Green space therapy, Outdoor activities for mental health?

Research shows that spending time in nature can help improve mental health by reducing feelings of depression and anxiety, and increasing positive emotions. Nature-based activities, like gardening and green exercise, have been found to be effective for adults, including those with existing mental health issues.12345

Is nature exposure safe for mental health treatment?

Research on nature-based interventions for mental health shows they are generally safe and can improve mental well-being, with no significant safety concerns reported in the studies reviewed.12346

How is the nature exposure treatment different from other mental health treatments?

Nature exposure treatment is unique because it involves spending structured time in natural environments, like parks or gardens, to improve mental health, rather than using medication or traditional therapy. This approach leverages the calming and restorative effects of nature, offering a non-invasive and accessible option for mental health improvement.13467

What is the purpose of this trial?

This project will first examine nature opportunities, belonging and benefits with a multi-state nature-based intervention with a focus on students of color. In light of the syndemic, 'nature deficit disorder' and poor mental health, the investigators anticipate several far-reaching impacts that will (a) test a nationally useful standardized way to quantify exposure; (b) invest in nature resources and accessibility on campuses; and (c) promote the mental health and therapeutic benefits of nature among young adults. These will lead to understanding the nature exposure and mental health interplay and techniques for quantifying and encouraging nature exposure to treat the on-going youth mental health crisis. Including HBCUs and an hispanic-serving institution is expected to result in heightened visibility of underlying disparities, including structural racism and land-based violence and discrimination, that have contributed to current-day nature gaps and dismantled nature relationships for students of color.

Eligibility Criteria

The Nature IDEAS Study is for students of color who are experiencing mental health issues. It aims to explore the therapeutic benefits of spending more time in nature, particularly on college campuses. The study will include participants from historically black colleges and universities (HBCUs) and a Hispanic-serving institution.

Inclusion Criteria

I am an 18-24 year old undergrad at one of the specified universities, living within 30 miles of campus.

Exclusion Criteria

Not an undergraduate student in one of the included universities
Live further than 30 miles from the university campus

Findings from Research

Nature-based interventions (NBIs), such as gardening and green exercise, significantly improve mental health outcomes in adults, including reducing depressive mood and anxiety, based on a systematic review of 50 studies involving various formats and durations.
The most effective NBIs were conducted over 8 to 12 weeks, with sessions lasting between 20 to 90 minutes, indicating a structured approach is key to maximizing their benefits.

Green social prescribing, which involves nature-based activities, has been shown to improve biopsychosocial wellbeing in community-living adults with mental illness, based on a review of 6 studies involving 334 participants.
Despite the variability in study designs and participant demographics, all studies indicated positive outcomes, suggesting that nature therapy could be a valuable intervention for mental health, warranting further research and standardized practices.

Engaging with natural environments can significantly enhance health and well-being, suggesting a potential benefit for mental healthcare practices.
Targeted nature-based interventions, known as green care, could be tailored to meet individual recovery needs, paving the way for further research to identify the most effective strategies for different populations.
