Effects of Extreme Heat
Extreme heat can occur throughout the summer months and can cause heat-related illnesses, exacerbate previous medical conditions, and potentially result in death. Extreme heat can lead to heat cramps, heat exhaustion, and heat stroke. Sustained exposure to extreme heat can pose a serious risk to many individuals. If the temperature inside a home is above 31°C for a sustained period of time, then there is significant increase in the potential risk for heat-related illnesses in susceptible groups.
The body has to work hard to cool itself down when exposed to extreme heat. It works to cool itself through the evaporation of the sweat, but in extreme heat, the body’s natural cooling mechanism may require additional support. Hydration and cool environments can help the body to cool itself down and avoid heat-related illnesses.
Heat alerts are shared through the Heat Alert and Response System to help warn people about the onset of extreme heat events.
