“If you have to start with opening a window….that’s OK.” by Dr. Robert Zarr
TEN MINUTES: of gardening or a weekly visit to a public garden can alleviate depression
TWENTY MINUTES: spent hiking among trees, bird-watching or pursuing other activities in nature reduces cortisol, the stress hormone.
THIRTY MINUTES: of sitting or walking in a park setting can lower blood pressure and heart rate.
FORTY-FIVE MINUTES: or more of hiking in the mountains results in less fatigue and higher alertness than the same amount of time spent indoors on a treadmill.
SIXTY MINUTES: spent interacting with nature, such as walking in urban parks or on tree-lined streets, can boost memory and attention span by 20%
