Heat Waves: Causes and Effects

The video explains heat waves, which occur when temperatures exceed the local average for three days. It describes how they form due to high atmospheric pressure, leading to direct sunlight and reduced moisture. The effects include health risks like heat stroke, infrastructure damage, and increased energy demand. Climate change exacerbates these events. To cope, stay hydrated, avoid peak sun hours, and wear appropriate clothing.
