Heatwaves are becoming more common and more dangerous in many places. UNEP shared practical ideas for staying cooler during very hot days. People can close curtains before sunlight enters a room. They can open windows when outdoor air becomes cooler. A fan can move air across the skin and help people feel cooler.
Drinking water often is important, even before someone feels thirsty. Light clothes and a cool shower can also lower body heat. Outdoor activity is safer during cooler hours. People should check older neighbours, children, and others who may need help. These small actions can reduce risk while communities prepare for extreme heat.
