In a bustling city like Ho Chi Minh City, where do you meet your friends to relax? For many teenagers, the answer is a local park. But these green areas are more than just social spots. Planners call them a city’s “green lungs” because they are essential for the health of the city and its people. These spaces offer hidden benefits that we often take for granted.

The most obvious benefits are environmental. Trees and plants in parks are fantastic at improving air quality. They absorb harmful pollutants from traffic and release clean oxygen. This cleaning process is vital for public health. Furthermore, parks help cool down cities. Concrete and buildings trap heat, creating an “urban heat island,” but the shade from green spaces can lower temperatures, making urban life more comfortable.

Beyond the environment, green lungs have huge social and mental benefits. They are natural meeting points that encourage community connection and reduce feelings of isolation, which can be common in dense urban areas. Having a quiet place to walk or play sports helps decrease stress and improve mental well-being. For teenagers, a safe and free public space to socialize is incredibly important.

So, the next time you are on a park bench, remember you are in a special place. These green lungs are a powerful investment in a healthier, happier, and more connected city. Protecting and creating these spaces is one of the smartest things a city can do for its future.
