Already 60% of Poles live in cities. Migration from the countryside to the city or from a smaller city to a larger one gives better prospects, but it brings many challenges. One of them is stress caused by detachment from your family and friends, higher noise levels, poorer air quality or requirements at the university or workplace. One of the remedies for stress is urban greenery and greenery in general.
Why green spaces are needed ?
"Must there be green in cities? It takes a valuable place. Is not enough green in the countryside? " - this may be your reaction to the introduction of this article. We fully understand this approach, which is why we present you with the problems that modern cities are facing.
Let's start with the fact that the World Health Organization (WHO) and numerous studies emphasize the positive effect of greenery on mood and mental and physical health. Green urban spaces, such as parks, allotments, forests and playgrounds are the place to practice sports, relax or socialize. And as you know - interpersonal relationships have a measurable impact on our health ?
On hot summer days these places are the only place where you can cool down. This is especially important in connection with the increasing amount of concrete and the increasingly tighter buildings of large cities. This means that the temperature in them significantly exceeds the temperature outside the city, which makes it even more difficult to withstand the heat. This is especially dangerous for children and the elderly, who exceptionally bear heat.
In winter, city dwellers experience the other side of the problem - smog. The increasingly tighter construction causes the liquidation of free green spaces and the building of the sewage system, which was a kind of urban ventilation. The result is that on days without wind and rain, smog literally stands still and covers the tops of multi-storey buildings.
Green spaces improve air quality, reduce noise, lower the ambient temperature and diversify the urban landscape. But what do studies have to say about green zones in cities?
We recall the most reliable analysis, covering as many as 9 other scientific studies from the United States, Canada, China, Italy, Spain, Switzerland and Australia. The analysis covered up to 8 million people and was published in 2019 in the prestigious medical journal The Lancet Planetary Health.
In all studies, scientists looked for the relationship between the proximity of greenery and the probability of premature death, regardless of the cause. And they found him!
It turned out that as closer you live to greenery, as more likely you will live longer.
You are not surprised, right? After all, most of us live in a crowded estate, where even a small bush is missing? Or maybe you work in a concrete jungle? Do not worry.
According to a 2014 study, enriching the office with plants increased employee productivity by 15%. Furthermore, air quality and job satisfaction have also improved. The authors of the study say that plants have increased the emotional and physical involvement of employees and improved their brain abilities.
However, does this translate into home conditions - children trying to do homework or students studying for the exam? Yes!
A 2015 study proves that 40-second breaks from work, during which students look at greenery, positively affect them.
How? Students make fewer mistakes and are persistent in their studies. Isn't this something that every parent wants for their children, and every student - especially before the session?
With 60% of Poles living in cities we are only one step away from the United States, where this percentage is 63%. Therefore, we must focus more on creating green spaces in apartments, houses, schools or offices and spending free time in parks, on playgrounds or in forests.
