research & evidentiary support
Nature has supported human healing for thousands of years. Modern science is now beginning to explain why.
What the research says
A growing body of international research shows that time in nature can:
​
• Reduce stress, anxiety and blood pressure
• Improve mood and emotional well-being
• Strengthen aspects of immune function
• Improve sleep quality and energy levels
• Restore focus, attention and mental clarity
• Increase creativity and problem-solving ability
• Encourage connection, generosity and social wellbeing
• Support people recovering from cancer and other long-term health conditions
The 5 most surprising things
...Scientists Have Discovered About Nature and Health
1. Even a view of nature can help people recover from illness
Hospital patients whose rooms overlooked trees recovered faster after surgery than those looking at a brick wall.
​
2. Just 20 minutes outdoors can significantly reduce stress
Short periods in parks or natural environments can lower cortisol, the body’s main stress hormone.
​
3. Forest environments may strengthen the immune system
Studies of “forest bathing” show increased natural killer cell activity.
​
4. Nature can improve focus and creativity
Research shows improved memory and concentration after time spent in natural settings.
​
5. Nature can make us kinder and more connected
Experiencing natural beauty can increase generosity, cooperation and social connection.
Research 30 seconds
Research from psychology, medicine, neuroscience and public health shows that spending time in nature can calm the nervous system, reduce stress hormones, improve mood, support sleep and restore attention.
​
Studies have found benefits from walking in green space, sitting quietly among trees, hearing natural sounds and even viewing nature through a window. Emerging research also suggests that nature-based activities may help people recovering from cancer or living with long-term illness by improving well-being, reducing fatigue and helping people reconnect with life beyond their condition.
​
Nature is not a substitute for medical care — but growing evidence suggests it can be a powerful complement to it.
