Australia’s rising heatwaves pose serious risks, especially for its ageing population. As extreme heat events grow in frequency and intensity due to climate change, seniors face unique challenges that demand urgent attention. From innovative solutions like heat alarms to practical safety tips and community support, protecting older Australians during heatwaves requires a multifaceted approach.
Rising Heatwaves Threaten Seniors in Australia
Extreme heat events are becoming more frequent and intense in Australia due to climate change. These heatwaves can have severe consequences, particularly for vulnerable populations, including seniors. The ageing population in Australia makes it crucial to address the unique challenges they face during extreme heat.
To illustrate, NSW health officials reported during the AFL 2023 Grand Final weekend that at least nine fire bans were in effect for the northern slopes down to the ACT/Victoria frontier, and Sydney temperatures on 1 October went above 35 degrees Celsius – the hottest spring weather for the city; temperatures at MCG during the game were at 29C.
In the weekend before Australia Day 2024, the Guardian reported that some towns in WA had temperatures in the late 40s, such as Paraburdoo at 47.9C and Onslow airport at 48.3C.
Heat Alarms Protect Seniors
One effective way to protect seniors from extreme heat is by implementing heat alarms. These devices can provide early warnings of rising temperatures, allowing seniors to take necessary precautions and seek assistance when needed. The following are some reasons why heat alarms for seniors are essential.
Early Warning
Heat alarms can detect temperature changes and trigger alerts when conditions become dangerously hot, providing seniors with valuable time to prepare or evacuate if necessary.
Independence
Seniors who want to age in place can maintain their independence with the help of heat alarms. They can receive warnings without relying solely on caregivers or family members.
Peace of Mind
Heat alarms offer peace of mind for both seniors and their families. Knowing that there’s a safety net in place can reduce anxiety during extreme heat events.
Timely Assistance
In case of emergencies, heat alarms can automatically alert emergency services or caregivers, ensuring that seniors receive assistance promptly.
Customisable Alerts
Seniors can tailor alarm settings to their specific needs, such as setting temperature thresholds for warnings or choosing to receive alerts via text message or phone call.
Special Systems under Development
Research on creating a specialised heat alarm system for the elderly is already underway in Australia.
In September 2023, a Griffith University research team announced trials for a digital in-home heat warning system for seniors for the 2023-2024 summer season under PROJECT ETHOS – Extreme Heat and Older Persons. The programme will be open to Queenslander seniors at least 65 years old with no cognitive or dissociative disorders and are willing to answer a comprehensive health questionnaire.
The system comprises a base station device and a set of sensors to be placed at certain spots in the home; these sensors will monitor the space for temperature and humidity changes and send a warning if temperatures get too high, including a senior’s body temperature. From there, the device will give seniors unique cooldown options. The research team will also talk to trial participants and collate their feedback towards improving the system, with a second stage of tests set for summer 2024-2025.
Essential Heat Safety Tips for Seniors
In addition to heat alarms, seniors and their caregivers should follow essential health tips to stay safe and comfortable during extreme heat periods:
Stay Hydrated
Seniors are more prone to dehydration, so it’s crucial to drink plenty of water throughout the day. If possible, the water must be mixed with block ice or electrolyte supplements, some of which are available in fruity flavours.
Keep Cool
A cool environment at home may be possible by using fans or air-conditioning units. Spend time in air-conditioned public spaces like shopping centres or libraries during the hottest parts of the day.
Wear Appropriate Clothing
Choose lightweight, loose-fitting clothing in light colours to reflect sunlight. A wide-brimmed hat and sunglasses can also help protect against the sun’s rays.
Plan Outdoor Activities
If outdoor activities are necessary, plan them for the cooler hours of the day, such as early morning or late evening. Avoid strenuous activities during peak heat.
Stay Informed
Pay attention to weather forecasts and heat warnings. Make use of heat alarms or other alert systems to stay updated on changing conditions.
Check on Neighbours
Seniors living alone should establish a buddy system with neighbours or friends who can check on them regularly during extreme heat events. In discussions with The Conversation, Griffith University professor Shannon Rutherford and doctorate student Sarah Cunningham said a neighbour keeping watch over another during a heatwave may be vital to combat loneliness seniors ageing in place often face.
Medication Management
Seniors taking medication should consult their healthcare providers about how extreme heat may affect their treatment. Do you know that medications can increase susceptibility to heat-related illnesses? A list from the Department of Health, Victoria includes common medicines such as, among others, antidepressants like olanzapine (stimulating heat production) and beta-blockers like atenolol (tightens up arteries instead of widening them for more blood flow).
Cooling Strategies
Use cooling strategies like taking cool showers, using damp washcloths, or applying cold packs to the wrists, neck, and forehead to lower body temperature.
Eat Light
Opt for light, easy-to-digest meals that don’t require cooking. Avoid heavy, hot meals that can raise body temperature.
Know the Signs of Heat-Related Illnesses
Seniors and their caregivers should be aware of the signs of heat exhaustion and heatstroke, such as confusion, rapid pulse, nausea, and flushed skin. If these symptoms occur, you will have to call for medical attention.
Aged-Care Support for Heatwaves
Protecting seniors from extreme heat is not solely the responsibility of individuals and their families. Aged-care support services play a vital role in ensuring the well-being of seniors during heatwaves. Here are some ways in which aged-care support can make a difference:
Check-In Services
Aged care support organisations can provide regular check-in services, particularly during extreme heat events, to assess seniors’ well-being and offer assistance if needed.
Heat Relief Centres
Establishing heat relief centres in communities can provide seniors with a safe and cool place to escape the heat when their homes are not adequately cooled.
Education and Outreach
Aged-care support providers can educate seniors and their families about the risks of extreme heat and the importance of preparedness.
Transportation
Arrange transport services to help seniors reach cooling centres or medical facilities if necessary.
Conclusion
Addressing the challenges posed by extreme heatwaves to Australia’s ageing population requires a collective effort. From implementing innovative solutions like heat alarms and promoting essential safety practices to enhancing aged-care services and fostering community support, protecting seniors during heat events is a shared responsibility. By combining individual preparedness with systemic interventions, we can help ensure that vulnerable populations remain safe, comfortable, and resilient in the face of intensifying climate impacts. Proactive measures today can save lives and improve the quality of life for seniors as Australia continues to confront rising temperatures.
