Extreme heat refers to unusually high temperatures that can pose health risks to humans and animals. It is often defined as temperatures that exceed 90°F (32°C) for several consecutive days. This phenomenon can lead to heat-related illnesses, such as heat exhaustion and heat stroke, especially among vulnerable populations like the elderly and children. Extreme heat can also impact the environment, causing droughts and affecting water supply. It is often linked to climate change, which increases the frequency and intensity of heatwaves. Communities may implement measures, such as cooling centers and public awareness campaigns, to help mitigate the effects of extreme heat on public health.
