10 more trees in a city block can make you feel 7 years younger?

Trees not just one of the essential elements in nature, but in cities too - not only do they offer us shade from sun and rain, they are also closely related to our health!


A research in UK has shown that people residing near trees or green spaces are less likely to suffer from anxiety and depression, making trees beneficial for residents’ mental health in the long run [1]. Another study conducted in Toronto, Canada indicates that residents in neighbourhoods with a higher density of woods suffer from less cardiovascular diseases. Even just ten more trees planted in a city block results in benefits: in residents’ self-report of health, it is as if they are seven years younger or has their annual salary increased by over 60,000 HKD– that is how important trees are to our health [2]!


On the flip side, forests all over the world are overcut to make way for development. Research has suggested that the death of trees will lead to the weakening of our respiratory systems [3]. The loss of the woods will lead to the worsening of air quality as less oxygen are released through trees, leaving us unable to exposure to the greenery which will brings us lots of health benefits (details please refer to the previous posts in the series~)


The loveliness of nature isn’t to be taken for granted. We are part of nature, we are all interlinked, tree live and we live.
