Go outside, your body will thank you.

Spring has sprung! The birds are singing, the sun is out and it’s time to put away your winter jackets for the season. Researchers have studied the impact of nature on human well-being for years, but recent studies have found a more direct correlation between human health, particularly related to stress, and the importance of people’s access to nature and managed landscapes.

Tensed or stressed out? Head to the cottage or local park. One study found that students sent into the forest for two nights had lower levels of cortisol — a hormone often used as a marker for stress — than those who spent that time in the city.

We know the natural environment is “restorative,” and one thing that a walk outside can restore is your waning attention. In one early study, researchers worked to deplete participants’ ability to focus. Then some took a walk in nature, some took a walk through the city, and the rest just relaxed. When they returned, the nature group scored the best on a proofreading task. Other studies have found similar results — even seeing a natural scene through a window can help.

People who live within a half mile of green space (such parks, public gardens, and greenways) were found to have a lower incidence of fifteen diseases by Dutch researchers — including depression, anxiety, heart disease, diabetes, asthma and migraines.

Get down and dirty! Soil is the new Prozac, according to Dr. Christopher Lowry, a neuroscientist at the University of Bristol in England. Mycobacterium vaccae in soil mirrors the effect on neurons that Prozac provides. The bacterium stimulates serotonin production, which explains why people who spend time gardening and have direct contact with soil feel more relaxed and happier.

Living landscapes help you heal faster. Multiple studies have discovered that plants in hospital recovery rooms or views of aesthetically-pleasing gardens help patients heal up to one day faster than those who are in more sterile or harsh environments.

All of these benefits reinforce the importance of maintaining our yards, parks and other community green spaces. Trees, shrubs, grass, and flowering plants are integral to human health. Not only do they provide a place for kids and pets to play, they directly contribute to our mental and physical well-being.
