The Biophilia Hypothesis states that people have an innate need or connection to nature or natural processes. This means that people may feel happier or more at peace when they are in natural environments like forests, or when they are interacting with plants or animals. It has been shown that when people are in natural settings, they have reduced stress, greater energy, and improved mental and physical health. The idea behind this hypothesis is that the connection between people and nature is hard-wired into us, which is why we can benefit from it.
