Environmental Nonprofits That Make Us Healthier

Have you ever taken a hike, strolled through a park, gone for a swim outdoors, or just sat in your yard and found yourself suddenly feeling better, more relaxed—even fulfilled? Well, it’s not your imagination or an illusion. The truth is that being outside and around nature has very real benefits to both your physical and mental health. More and more, scientists and researchers are connecting the dots between a healthy environment, access to the outdoors, and healthy humans. (As if we needed another reason to love our planet!)

According to Michelle Kondo, a research social scientist with the USDA Forest Service’s Northern Research Station, “There are many physical and psychological benefits of nature that scientists have observed, which can better help us understand how nature supports wellness in the body, mind and community.”

Improving Your Physical and Mental Wellbeing

From a physical perspective, being outside in green spaces supports an active and healthy lifestyle, which can increase life expectancy, improve sleep quality, and reduce the risk of various cancers. In addition, being outside in nature often promotes relaxation, which in turn reduces stress, cortisol levels, muscle tension, and heart rate – all major contributors to cardiovascular disease.

When it comes to mental wellness, being outside can lower a person’s risk of depression and promotes faster psychological stress recovery. Studies also show that being in nature can restore and strengthen our mental capacities, increasing focus and attention.

According to University of Chicago psychologist Marc Berman, PhD, “Green spaces near schools promote cognitive development in children and green views near children’s homes promote self-control behaviors.” Even just looking at trees has been shown to be able to reduce stress, lower blood pressure, and improve mood.

Exploring the Outdoors with Others

The benefits of being in proximity to healthy outdoor spaces are not just about personal benefits. A recent study conducted by L.L Bean and University of California Irvine (UCI) shows that “Those who spent time outdoors in company of others…said the experience was 28% more meaningful and 37% richer.” In other words, being in nature can help create deeper, more meaningful social connections. The natural world around us is helping to bolster the social fabric of our societies.

With more studies coming out weekly, the connections drawn between human health and nature will only increase. Whether you look at this issue from an ecological or human perspective, the importance of creating healthy, green spaces and providing access to outdoor recreation is obvious.

The list below represents a selection of nonprofits helping to do just that.
