Over the years, a growing body of research has proven that regular access to trees makes us happier and healthier. They restore our sense of calm from head to toe — improving memory and attention span, enhancing cognitive functioning, lowering blood pressure, and reducing cortisol levels.

In honor of Mental Health Awareness Month, here are just a few ways trees can support your mental well-being.

• Spending time in nature reduces levels of a stress hormone called cortisol. It also lowers blood pressure.
• Living within 100 meters (about 300 feet) of a tree can reduce rates of depression.
• Being among the trees (or even climbing them!) enhances cognitive functions such as learning, thinking and reasoning.
• Walking through green space with trees can improve memory and attention span.

This month (and every month), make a conscious effort to get out and enjoy the trees around you, whether in your own yard or a community space. Take note of the positive effects nature has on your mood and overall health. Visit the Arbor Day Foundation website for more information about the correlation between trees and health.
