Climate and Health: Extreme Heat
Extreme heat is a period of high heat and humidity with temperatures above 90 degrees for at least two to three days in a row. When hot temperatures combine with high humidity, your body works extra hard to maintain a normal temperature, which can cause serious heat-related illnesses and even death.
