Summer Clinical Alert 2025–26
Preventing Heat Stress in Older People
BAMBOO HOME SUPPORT (BHS)
With rising temperatures across Australia, summer presents a significant health risk for older people. Heat causes more deaths each year than any other natural hazard. During heatwaves, the impact on older people can be severe and sudden.
People Over 65 Are at Highest Risk
As we age, the body becomes less able to regulate temperature. Older people sweat less efficiently, feel thirst less strongly, and take longer to respond to sudden heat stress. Heat-related illness can escalate rapidly and may lead to serious deterioration or death.
Seek urgent medical help if you notice:
- Sudden rise in body temperature
- Confusion or altered mental state
- Seizures
- Nausea or vomiting
- Loss of consciousness
- Weak or rapid pulse
This is a medical emergency. Begin cooling immediately and call 000.
Additional Risk Factors
Risk is higher for older people who are frail, have low body weight, dementia, difficulty staying hydrated, or mobility challenges that limit their ability to cool themselves.
Know the Environment
Identify rooms that heat quickly, areas with direct sunlight, and outdoor spaces that change temperature. Ensure participants are dressed appropriately and not left unattended in hot areas.
Fluid Intake and Preventing Dehydration
Encourage frequent fluid intake. Watch for signs of dehydration such as dry mouth, reduced toileting, or heat rash. Offer lukewarm showers or sponging and ensure sun protection.
Providing Home Care in the Heat
Home care workers should have a Heat Action Plan for vulnerable participants, ensure access to fluids and cooling, and know how to respond to heat stress emergencies.
If You Are Concerned – Act Early
Contact family, the GP, or emergency services (000) as appropriate.
Stay Cool. Stay Hydrated. Stay Safe.
