How can you cool down a city?
Blue infrastructure
Like green spaces, blue infrastructure, involving water bodies like ponds, rivers and dams, can be a powerful tool for temperature reduction. Integrating water features with green spaces can also help lower the temperatures of surrounding areas.

What makes cities hotter?
Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun's heat more than natural landscapes such as forests and water bodies. Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas.
What are the solutions to extreme heat?
Summary. Keep cool: use air conditioning or a fan, wear light and loose-fitting clothing, and keep skin wet, using a spray bottle or damp sponge and by taking cool showers. Stay hydrated: during days of extreme heat, keep drinking water before you feel thirsty, especially if outdoors or performing physical activity.
How can we reduce heat waves?
Planting trees and other vegetation lowers surface and air temperatures by providing shade and cooling through evapotranspiration. Trees and vegetation that directly shade your home can decrease the need for air conditioning, making your home more comfortable and reducing your energy bill.
