Spending time in green spaces is linked to higher cognitive function in middle-aged women, which is a significant predictor of lower dementia risk later in life. Researchers have also found that increased exposure to green spaces, reduced air pollution, and higher physical activity levels are associated with a decreased risk of depression, another crucial factor in cognitive decline.
The positive effects of being in nature are attributed to fractal patterns, self-repeating patterns of varying scales found in natural environments, like the veins on a leaf or patterns in tree bark.
Humans have evolved to find comfort and calmness in these patterns, and exposure to them can reduce stress and mental fatigue by up to 60%. Hospitals with views of natural fractals can aid in faster healing and recovery for patients.
