And yet we are moving further and further away from it: data provided by ONU say that 50% of the world's population now lives in metropolitan areas, and the proportion is increasing rapidly. Therefore, caring for the design of cities to ensure the best possible conditions becomes fundamental.
In fact, the presence of trees and other elements of urban nature, even of a simple view of a park from home, has a significant effect on the health of the residents.Alcuni anni fa una ricerca olandese condotta su quasi 350.000 persone ha dimostrato che vivere a meno di un chilometro da un’area verde è protettivo per molte malattie: da quelle cardiovascolari alle respiratorie, dal mal di testa ai disordini dell’apparato digestivo, fino ai dolori muscolari e, soprattutto, all’ansia e alla depressione.
This and other studies show that it is above all psychological well-being that benefits the most. The green, in fact, allows us to recover from stress and fatigue generated by the excessive stimulation of all our senses, typical of cities. In districts with more nature, as a result, negative emotions such as anger, frustration, aggression, anxiety and sadness are reduced; while positive ones, such as self-esteem and self-control, are reinforced.
