Green spaces in cities are often praised for their positive effects on health.  People living in urban areas are increasingly looking for ways to connect with nature. In urban settings, green spaces are commonly known to provide health benefits. These benefits have been documented for a long time.

Such benefits range from improved mental health to early prevention of diseases.

However, not all green spaces are created equal.  It turns out that not all green spaces are equally beneficial to our health.

This study delves into the concept of a threshold model.  This advanced model aims to capture both the positive and negative effects of green spaces on our bodies.

To test this, participants were shown images of healthy urban greenery and distressed urban greenery.  They were connected to machines to track their brain activity.  Both types of greenery had similar effects.

The negative effects of distressed urban greenery were significant.  They went beyond just reducing the positive effects of green space.  Exposure to distressed urban greenery negatively impacted health.

Women were more likely to feel the negative effects of distressed urban greenery than men.  It is important to note the differences between men and women.

After being exposed to distressed urban greenery for a prolonged period, the recovery effects were stronger.  This was especially true with healthy urban greenery.

The study highlights the effectiveness of the threshold model.  It shows the complex interactions between humans and their environment. The model offers a deeper understanding of the health impacts of green space exposure.

The study also suggests the need for more research.  This is to better understand these complex interactions.
