Before we explore the answers to these questions, it may help to define what we mean by “nature”, as the term has a very broad definition. It can be used to refer to green spaces of varying sizes, such as parks, gardens, or forests; to blue spaces, like rivers, lakes or oceans; or to elements of the wider world that we have incorporated into our urban or domestic environments, for example, street trees, house plants and pets.
Conscious, sensory contact with any form of nature, regardless of its size, has been shown to offer health benefits. Of course, large, immersive environments such as forests are likely to yield more benefits than smaller ones, and the more regular the contact, the better.
According to one study published in Nature, spending at least two hours per week in natural settings is linked to good health, regardless of whether this time is spread over several days or concentrated into one or two. However, any less than two hours per week, and you won’t receive the same benefits.
