The Department of Health is urging Western Australians to prepare for extreme heat this summer, warning that prolonged high temperatures can cause serious health issues, even in otherwise healthy people.
The Bureau of Meteorology's long-range forecast shows large parts of the State are likely to experience above-average daytime temperatures this summer, with northern and coastal regions facing unusually warm nights.
Warmer nights mean that the body cannot cool down from the daytime heat.
WA Chief Health Officer Dr Andrew Robertson said everyone should take the risk of heatwaves seriously.
"Extreme heat is Australia's deadliest natural hazard," he said.
"We're seeing longer, hotter and more frequent heatwaves and Western Australians should prepare early and take precautions when temperatures climb."
Dr Robertson said extreme heat could strain the heart, cause dehydration and heat exhaustion, and, if untreated, can be life-threatening.
"Even fit and healthy people can be affected if they don't take precautions," he said.
"It's important to stay hydrated, rest in cool places during the hottest part of the day and look after each other."
Tips to stay healthy during a heatwave:
- Drink plenty of water, even if you don't feel thirsty
- Seek shade or air-conditioning during the middle of the day
- Avoid strenuous activity when it's hottest
- Wear light, loose clothing and use sunscreen outdoors
Dr Robertson encouraged people to check on vulnerable community members during prolonged periods of extreme heat.
"Heatwaves hit hardest when people are alone," he said.
"Check in on neighbours, older relatives, friends and those who are unwell or living alone - a quick call or visit can make all the difference."
People at greatest risk include older adults, babies and young children, pregnant women, and people with chronic health conditions; however, no-one is immune to the effects of extreme heat.
Heatwave health alerts will be issued through Emergency WA, ABC Radio and other broadcasters.
