Summary
In our increasingly urbanised world, it’s important to make time for reconnecting with nature. The latest study to grab our attention in this area was conducted by the Barcelona Institute for Global Health and published in December 2022. It looked into the so-called 3-30-300 rule, which was theorised by Spanish forest researcher Cecil Konijnendijk in 2021. It's made up of three criteria, which each give our mental health a boost: we should have three trees in view from our home, live in a neighbourhood with 30% tree canopy cover and live within 300 metres of a park. Researchers interviewed over 3,000 residents in Barcelona and found that less than 5% of them were lucky enough to live in an area which met all three of the 3-30-300 rule’s criteria. Indeed, 22.4% of respondents had none of the elements. Interesting, so what did we learn from the latest study? What is it about green spaces that makes us calmer?
