Nature Review of 3,800 Studies Links Nature Contact to Lower Anxiety and Depression
2 articles · Updated · Psychology Today · Jul 2
Summary
A 2026 global review in Nature covering more than 3,800 studies and 10 million people found contact with nature reduces anxiety and depression symptoms while promoting relaxation.
The evidence spans viewing nature, being in natural settings and activities such as gardening or forest meditation, with prior reviews also linking exposure to better cognition, sleep, blood pressure and overall well-being.
Researchers cited possible mechanisms including biophilia, lower heart rate and blood pressure, reduced cortisol and amygdala activity, and less prefrontal activity associated with relaxation.
The paper says the findings support using natural environments in mental-health strategies, urban design and education, while noting some questions—such as effects on attention—still need more rigorous trials.
Science now prescribes nature for mental health. How can our cities ensure this 'green medicine' is available to everyone?
