An extended stretch of exceptionally hot weather, generally lasting two or more days, is called a heat wave. The prolonged heat wave denotes a condition in which the temperature exceeds the region's all-time high. 

There is a clear correlation between climate change and the increase in heatwaves. As global temperatures rise due to greenhouse gas emissions, heatwaves become more common. Each fraction of a degree in global warming can significantly increase the likelihood of heat-related events.

Public awareness is vital in combating and coping with heatwaves. Communities should be informed about the risks and the simple steps to stay safe. Local governments and media play a crucial role in disseminating timely information, opening cooling centers, and providing resources for vulnerable populations.
