If you need emergency assistance, ring triple zero (000).

People suffer heat-related illness when their bodies can no longer effectively cool. Very high body temperatures can damage vital organs and the brain. Heat-related illness is preventable by:
- Avoiding vigorous outdoor activities on hot days
- Drinking plenty of cool, non-alcoholic beverages (speak with your doctor if you are on a limited liquid intake program)
- Staying in air conditioned buildings (libraries and shopping centres are an alternative for people who do not have air conditioned homes)
- Avoiding prolonged periods in the sun
- Take a cool shower, bath or sponge bath
- Wearing lightweight clothing and sunblock
- Monitoring people at high risk (eg elderly neighbours)
- NEVER leaving children or pets unattended in cars.
