Take action when you see symptoms of heat exhaustion and heat stroke.
To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments.
Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.
The urban heat island effect occurs when urban areas become much warmer—sometimes by as much as 20°F—than nearby rural landscapes, especially during summer.
According to NASA, this happens because cities have more heat-absorbing surfaces like asphalt, concrete, and buildings, and less vegetation to provide cooling through shade and evapotranspiration.
