Summer can be a wonderful time for enjoying the outdoors and connecting with family, but for older Australians, extreme heat brings real risks. Those aged 65 and over are more vulnerable to heat stress, a serious condition that can lead to dehydration, confusion, and even hospitalisation if not caught early[1]. In older adults, not only are they more vulnerable to heat stress, but it can happen much more quickly and be much more serious that in healthy, younger adults.
At Home Care Assistance Australia, we see the impact of hot weather on our clients every year. That’s why it’s so important to recognise the warning signs, understand the risk factors, and know how to respond quickly.
Why Older Adults Are at Greater Risk
Heat affects everyone, but age-related changes in the body mean older adults are less able to regulate their temperature, making it harder to cool down. Older adults may also be less likely to detect that they are becoming dangerously hot until it is too late. Combined with health conditions or medications, even a mild heatwave can become dangerous for seniors.
Key risk factors include:
- Chronic conditions like heart disease, diabetes, kidney issues, or lung disease
- Medications that affect hydration (e.g. diuretics or blood pressure tablets)
- Reduced mobility, which can make it hard to seek cooler environments
- Social isolation, which may delay a response to symptoms
- Cognitive decline, which can impair judgment or awareness of thirst
These risk factors make seniors more susceptible to heat stress, less likely to notice the warning signs of heat stress, and less likely to seek timely treatment leading to a potentially dangerous situation and medical emergency arising.
Recognising the Signs of Heat Stress
Knowing the early signs of heat stress can prevent a dangerous situation from becoming an emergency. Be alert to any of the following symptoms:
- Lethargy or unusual tiredness
- Dizziness or fainting
- Muscle cramps
- Nausea, vomiting, or diarrhea
- Rapid heart rate
- Dark or decreased urine output
- Confusion, disorientation or sudden mood changes
- Headaches or blurred vision
- Excessive thirst
If your loved one begins to show these signs (especially in hot or humid weather) it’s essential to act immediately.
What To Do If You Suspect Heat Stress
If you notice symptoms of heat stress in an older person:
- Move them to a cool or air-conditioned space
- Offer sips of cool water, unless they are unconscious or vomiting
- Apply cold compresses to the neck, armpits and wrists
- Remove or loosen excess clothing
- Call a GP or seek emergency medical attention if symptoms worsen or don’t improve
Heat stress can escalate quickly. Don’t wait for multiple symptoms to appear – early intervention saves lives. It is much better to act cautiously and see help early than wait as the situation can deteriorate quickly in an elderly person making it more difficult to treat and leading to serious complications.
How to Prevent Heat Stress
The best way to avoid heat-related illness is through prevention. Here are some practical ways to stay safe during the warmer months:
Stay hydrated: Encourage regular small sips of water throughout the day—even before thirst is felt
Avoid the midday heat: Plan outings, appointments, shopping or exercise early in the morning or after sunset
Keep homes cool: Use fans, air conditioning, or visit cool public places like shopping centres or libraries. Often in a heatwave places like libraries will have extended opening hours for people who do not have cooling in their homes, or consider visiting a friend who does have cooling at home.
Wear lightweight, breathable clothing: Choose cotton or linen and opt for light colours
Use cooling aids: Cool cloths, mist sprays, or even a foot soak can help lower body temperature
Monitor medications: Some increase sensitivity to heat—check with your GP or pharmacist
Check in regularly: If your loved one lives alone, call or visit daily during heatwaves
Home Care Assistance Care Professionals are trained to monitor these risks and respond quickly to heat-related symptoms, providing peace of mind to families and a safer environment for older Australians.
