Heatwaves in Australia

As global temperatures rise, Australians will see heatwaves with increased intensity, frequency and duration. Heatwaves are measured when unseasonably high maximum and minimum temperatures remain for more than three days.1

This excessive heat can cause discomfort from day, into night. People who work outside are also placed at greater risk. When a heatwave occurs, the question of how to stay cool becomes a priority. Whilst staying inside goes a long way, maintaining a comfortable temperature in the home can be easier said than done.

Keep reading for our advice on how to stay cool in summer during an Australian heatwave.

Tips on how to stay cool in summer

If you’re struggling with the temperature during a heatwave or simply on a hot summer’s day – you’re not the only one. Extreme temperatures can have a real impact on how we feel and function during daily life. Here are our top tips on how to keep your home cool in summer.

① Stay hydrated

Keeping your body hydrated is an important step in staying cool when temperatures soar. Aim to drink at least two litres per day, avoiding alcohol, caffeine and hot drinks. Upping your intake of minerals like sodium, potassium and magnesium can help too, as drinks rich in minerals help to hydrate on a cellular level.

② Beat the heat with an air purifier

Figuring out how to keep the house cool in summer can be tricky during a heatwave, and hot summer nights bring a challenge of their own. To beat the heat, we recommend enlisting Dyson Purifier Cool™ Formaldehyde purifying fan. With Air Multiplier™ technology and 350-degree oscillation, Dyson Purifier Cool™ Formaldehyde projects air around the whole room2 to cool you, whilst simultaneously capturing 99.95% of pollutants3 that build up in the Summer heat such as smoke haze, gases4 and pollen. It has also been designed to be 20% quieter than previous models while maintaining optimal purification performance for a cooler, more peaceful night’s sleep.

③ Close curtains and shutters

Opening your windows to sunlight and breeze might seem like it’s helping, but this can create a greenhouse effect during a heatwave – with up to 30% of unwanted heat gain attributed to windows.5 It’s best to keep windows, curtains or shutters closed during the day to minimise the amount of sunlight entering the home. If temperatures dip during the night, this is the time to allow cooler air to circulate before closing them up again in the morning. However, temperatures typically stay high overnight during a heatwave.

See what Dyson Purifying fans can do for you this summer

  • A close-up of the LCD screen on a Dyson air purifier.

    Senses and reports automatically

    Most indoor pollutants can't be seen or smelled. Dyson air purifiers constantly monitor your indoor air quality – automatically sensing airborne particles and then displaying real-time reports on the LCD screen for proof of cleaner air.

  • A Dyson purifier on top of a box with no pollutants leaking out.

    Whole-machine sealed

    In our latest air purifiers it's not just the filter that's sealed to HEPA 13 standard, it's the whole machine.7 This prevents pollutants from being expelled back into the room after they've been removed from the airflow. So what goes inside, stays inside.

Frequently asked questions

No, Dyson fans and purifiers are not air conditioner units and therefore not designed to lower the room’s ambient temperature. Instead, Dyson products help to support the body’s natural cooling function by helping water evaporate from your skin. This in turn transfers heat from your body, making you feel cooler. Our devices provide you and your home with a powerful, targeted and pure cooling air flow.

Our purifier fans use Dyson Air Multiplier™ technology which generates the circulation power to draw even far-away pollutants into the machine, projecting purified air throughout the room.2 Because our air purifiers don’t have fast-spinning blades or grilles like conventional fans, they are safe and simple to clean.

Thanks to the bladeless design, Dyson air purifiers are engineered to ensure even the lightest sleepers can get a restful night’s sleep. During heatwaves, hot overnight temperatures can disrupt deep wave and REM sleep, leading to a restless night. Dyson Purifiers are 20% quieter than the previous generation so it can cool you without disturbing your sleep. And with the sleep timer feature, you can program it to turn off after preset intervals between 15 minutes and 9 hours.
