Heat, humidity, and health
Stay safe in the heat
Extreme heat can cause your body a lot of stress. The good news is that heat stress is preventable. Follow these tips to stay safe:
Stay hydrated. Drink plenty of water, even if you’re not thirsty. If you’re on fluid restrictions, talk with your doctor. Avoid alcohol and caffeine during extreme heatwaves as they contribute to dehydration.
Cool your body. Take cool showers, soak your hands or feet in water, or apply damp cloths or icepacks to your neck, armpits, or groin. A gentle swim can also be refreshing, just stay hydrated and stick to shaded areas.
Stay in cool places. Spend time in air-conditioned spaces like libraries, community cooling centres, or shaded areas with flowing air.
Avoid outdoor exercise. Skip strenuous exercise, like gardening, golf, or tennis, during hot days, even if you’ve tolerated this in the past.

Wear breathable, loose-fitting fabrics in light colours. Wear wide-brimmed hats if you go outside. Wet your shirt or hat for extra cooling.
Keep your home cool. Use fans and AC, close curtains during the day, and open windows at night when it’s cooler. Avoid using appliances that generate heat, such as ovens, clothes dryers, or hair dryers.
Stay connected. If you live alone, check in regularly with friends or family members, and encourage them to do the same for you.
Why is heat a risk to your health?
Heatwaves place a huge amount of stress on your body as it works to cool down. This can make underlying health issues worse, as your organs work hard to cool you down. It can worsen underlying conditions like heart, lung, or kidney diseases and increase the risk of hospitalisation. This is especially the case if you have multiple chronic illnesses.
Your ability to cool down and recognise heat stress decreases as you age. This makes older adults especially vulnerable. Even if you’ve tolerated heat well in the past, it’s important to know your limits and take proactive steps to stay safe.
Who is most at risk?
Your risk of heat stress increases when multiple of the following factors combine:
Being 65 or older
A heat index of 33C or higher (A heat index is a figure which considers how both the outdoor temperature and humidity combine to make you feel)
Chronic health conditions such as high blood pressure, diabetes, or obesity
Some medications can increase heat sensitivity (talk to your doctor or pharmacist)
Outdoor activity, such as gardening or exercise
Living alone, as it’s harder to keep track of your health and take cooling measures without support
Homes without air-conditioning (AC) or proper insulation, as they hold more heat
Living in isolated or low socio-economic areas, where help or resources may be limited

Recognising the signs of heat stress
Early signs of heat stress can include:
Heavy sweating
Thirst
Discomfort
Headache
Reduced alertness
Irritability
These are warning signs that your body is struggling to cope with the heat. If untreated, heat stress can progress into more severe conditions like heat exhaustion or heatstroke, which can be life-threatening.
What to do if you feel heat stress
You can take these steps to cool down:
Get to a cool, shaded place and lie down
Wet your skin with cool damp cloth, mist, or cool water
If lying down, you can submerge your hands and feet in cool water
Many older people in Australia don’t recognise heatwaves as a serious risk to their health. By being aware of the dangers and taking simple steps, you can protect yourself and reduce the impact of extreme heat.
