The Incredible Benefits of Nature (Wild. Here. List of Scientific Studies)

Better Mental Health (from seeing nature)

"People living in neighbourhoods with more birds, shrubs and trees around the home, whether people lived in urban or more leafy suburban neighbourhoods are less likely to suffer from depression, anxiety and stress." (Link)

Increases Positive Emotions (Awe, Contentment, Joy)

"Watching nature programs will have a direct and uplifting impact on the mood and well-being of its viewers, according to a new study released by BBC Earth, the BBC’s global factual brand. “The Real Happiness Project,” which aims to promote the benefits of connectivity with nature via linear and digital platforms, was conducted by BBC Worldwide’s in-house research team with Professor Dacher Keltner, who oversees psychology at the University of California, Berkeley"

Supports Relaxation and Recovery After Stress

"Keeping a few snapshots of greenery around your work desk might not be a bad idea. When participants viewed the natural images in the experiment, their stress levels lowered. "Viewing green scenes may thus be particularly effective in supporting relaxation and recovery after experiencing a stressful period, and thereby could serve as an opportunity for micro-restorative experiences and a promising tool in preventing chronic stress and stress-related diseases." the study states."

Restores Attention (less than One Minute)

"Participants who briefly viewed the green roof (for forty seconds) made significantly lower omission errors, and showed more consistent responding to the task compared to participants who viewed the concrete roof." (Link)

Decreases Stress Levels (Six Minutes)

This study of 160 people, showed that as "the amount of tree-density people viewed increased, so did stress reduction.  In other words, the denser the forest, the lower the stress, which suggests that taking a walk down a tree-lined street - or better yet, heading out to a park - could prove beneficial to your mental wellbeing."  As little as six minutes can decrease your stress levels.

More Cooperative (Twelve Minutes)

"The nature-focused, 12 minute videos once again had the effect of “producing more pro-social responses” in the fishing game. “These effects do not depend on nature’s pleasantness,” noted the authors." (Link)

Feeling more Positive 

"One recent study tested over 1,200 elderly adults. Those who had not engaged in outdoor recreation in the past year were the most prone to major depression. Those who spent time outside four or more times a week suffered the least depression." (Link)

Increases Empathy and Generosity

Both exposure to beautiful images and being in a room with beautiful plants increased participants "prosocial" tendencies including agreeableness, perspective taking and kindness.

Lower Feelings of Depression and Anxiety  (Fifteen Minutes)

"One study conducted at Japan's Kyoto University found that participants who went on a walk through pine forests (for 15 min) returned with significantly lower depression, hostility and anxiety levels. The study also found that stressed-out participants had a greater feeling of relaxation after being surrounded by the scent."  (Link)

Lower Stress Levels (Twenty Minutes)

"A 2013 study did just this, testing saliva sampled before and after study participants sat in various settings (natural and urban) for 20 minutes. They found evidence that spending time in a natural environment reduces stress."

As Energizing as Coffee (Twenty Minutes)

"Just 20 minutes outdoors can have the same pick-me-up effect as a cup of coffee because of the instantly energizing powers of nature, according to psychologists." (Link)

Psychological Benefits

"The degree of psychological benefit was positively related to species richness of plants and to a lesser extent of birds, both taxa where perceived richness corresponded with sampled richness. (Well-being measures focused on greenspace as a source of cognitive restoration, positive emotional bonds and sense of identity.) While benefits did increase with greenspace area, the relationships with plant and bird richness were generally stronger. " (Link)

Increase in Health

"The study showed that living in a green environment was positively related to all three available health indicators, even stronger than urbanity at the municipal level.  Basically health increased with the amount of greenspace in one’s living environment."

Increase in Healing Rates

"In 1984, a classic study found that hospital patients recovered from surgery quicker if their room offered a view of nature compared to those who looked out on a brick wall" (Link)
