Healthier Cities Will Require a Strong Dose of Nature

If current global trends are correct, by 2025, approx. 41 million people Non-communicable diseases (NCDs), including cancer, heart disease, diabetes, chronic respiratory diseases and severe mental illness, account for approximately 74% of global deaths. Despite significant medical advances over the past few decades, the number of deaths from non-communicable diseases continues to increase.

One of the main factors contributing to the increase in non-communicable diseases is urbanization: Research clearly shows People living in urban areas without green spaces have higher rates of non-communicable diseases. Given that by 2050, Two out of every three people Most likely living in cities, these trends are extremely concerning.

On the other hand, some recent population-level studies in global cities show those who live in green area Not only are the incidence of non-communicable diseases lower, but physical condition and health have also improved significantly mental health. This relationship remained statistically strong regardless of an individual’s socioeconomic status, age, or gender. In fact, the evidence for this link is so strong that by 2022, 196 countries United Nations Conference of the Parties on Biodiversity An international treaty was signed that included a commitment to significantly increase urban green space by 2030.

Why green spaces fight non-communicable diseases? More opportunities for exercise, cleaner air and less heat stress are all touted reasons – and there’s evidence to support some of the roles urban vegetation plays in these areas.

Importantly, there is also strong scientific evidence that when we interact directly with nature, biochemical pathways in our bodies are triggered, producing dramatic effects. beneficial health effects. This research topic began when a group of Japanese scientists tried to determine the true benefits of forest bathing –Visit the bath in person. The evidence they found is so compelling that now in Japan, patients with certain non-communicable diseases are not treated with medications but are prescribed prescription treatments Spend time sitting in the forest.

The good news is that we can get similar health benefits from urban green spaces and indoor vegetation. Clinical trials show that something as simple as having a Unscented rose vase For example, placing it on your desk can significantly lower blood pressure and bring about physical and psychological calm. It’s also okay to plant green leafy plants in your home and office, especially those with green and yellow leaves.
