In Australia, heatwaves have caused more deaths than any other natural disaster (DEA 2020), with older adults over 65 being one of the high-risk groups for hyperthermia.
Older adults are more susceptible to dehydration due to changes in the body that occur with ageing, including decreased thirst sensation, decreased kidney function, medications causing fluid loss, not recognising signs of dehydration, living alone, cognitive impairment and mobility issues.
The following tips will help prevent older Adults from experiencing hyperthermia (heat related illness) on hot days:
- Take note of the weather and take appropriate precautions if the temperature is over 30°C. Temperatures of over 37°C are particularly dangerous.
- Make sure the cooling systems in the home are operating correctly.
- In addition to water, ensure other fluid options such as jelly, ice-cream or fruit juice blocks are available for clients.
- Keep curtains and blinds closed in hot weather.
