Australia is facing an extreme heatwave this week, with temperatures forecast to soar above 40 °C across large parts of the country and in some inland areas potentially hitting the mid-40s. The Bureau of Meteorology has warned this could be one of the most significant heatwaves in years, affecting NSW, Victoria, South Australia, Tasmania, Western Australia, the ACT and more. Consecutive days of high temperatures and warm nights increase not only heat stress but also fire risk in many regions.
People who are older, frail, medically unwell and socially isolated are particularly vulnerable during extreme heat. Many people living with Dementia falls into one or more of these higher-risk groups, so targeted awareness and support from carers, family members and communities are essential.
Why Extreme Heat Is a Risk for People with Dementia
Heatwaves can be dangerous for anyone, but for someone living with Dementia there are a few extra challenges:
- Difficulty recognising or communicating thirst or discomfort - people with dementia may not always self-report being too hot or remembering to drink regularly.
- Impaired decision-making or routine disruption - usual routines like staying inside, closing curtains or using cooling systems may be forgotten.
- Medications and health conditions - some medications and underlying conditions can make it harder to regulate body temperature.
- Risk of dehydration, heat exhaustion or heat stroke - prolonged exposure may lead to serious health problems if not managed.
Practical Tips for Carers and Families
Here are ways you can help keep someone living with Dementia cool, safe and comfortable during this heatwave:
Create a cool environment
- Keep homes as cool as possible - use air conditioning where available, or create shaded areas.
- Close curtains and blinds early in the hottest part of the day to block out direct sunlight.
- If the home is too warm, consider visiting cooler public spaces (libraries, shopping centres) especially in the peak heat hours (typically 11 am–3 pm).
Hydration is key
- Offer water often - don’t wait for dehydration signs; someone with Dementia might not feel or express thirst.
- Use reminders if needed - regular time-based prompts or placing water bottles in easy-to-reach places can help.
- Avoid sugary, caffeinated or alcoholic drinks- they can increase dehydration.
Dress appropriately
- Choose loose, lightweight, breathable clothing (natural fibres like cotton are often more comfortable).
- Encourage a hat and sunscreen if heading outdoors in shaded areas.
Check-ins and routines
- Visit or call regularly - people with Dementia may have reduced awareness of weather risks.
- Keep daily routines consistent, but flexible for heat (e.g., morning walks rather than midday ones).
- Monitor for signs of heat stress - fatigue, weakness, dizziness, confusion or nausea.
Have a plan
- Prepare medications and supplies ahead of time in a cool spot - heat can affect some medications.
- Plan for potential power outages - have battery-operated fans, cool packs or safe backup options ready.
Watch for Serious Signs
If someone shows symptoms of heat exhaustion or heat stroke - such as rapid heartbeat, confusion, seizures, or rapid breathing - it’s critical to seek urgent medical help. Early cooling (shade, cool water, wet cloths) can reduce danger while help is on the way.
Support Beyond the Home
National services like the Australian Red Cross offer further heatwave preparedness resources, including tips and checklists for vulnerable people, and encourage communities to check on at-risk neighbours, family and friends.
Remember
Heatwaves are weather events we can prepare for, and your care makes a tangible difference. For people living with Dementia - who often rely on routines and support - your vigilance, kindness and planning help keep them safe, cool and comfortable during extreme conditions.
Caring for someone living with Dementia during extreme heat can be physically and emotionally demanding. If you’re looking for additional tools to help support daily care, we’ve curated a Carers Collection with practical products designed to assist with comfort, safety and routine.
