Incidents of depression and poor mental health can affect anyone at any time, but there is a recognised situation called nature deficiency disorder, which is more common in cities than rural areas.
This is where people with no or little access to gardens, public parks or green spaces may be at greater risk than those able to get outdoors and connect with nature.

Biophilia is defined as the innate and genetically determined affinity of human beings with the natural world. There are clear health links but research has not yet been able to fully reproduce the effect of simply being outdoors.

London's parks and green spaces are invaluable for public health and wellbeing, and we need more natural spaces to meet demand; especially as development becomes ever more dense.
