Victoria is heading into the warmer months, so now is the time to prepare for extreme heat.

Extreme heat does more than cause sunburn. It can worsen existing health conditions and, in severe cases, lead to life-threatening illnesses such as heatstroke.

"Extreme heat can become dangerous quickly" said Dr Caroline McElnay, Victoria’s Chief Health Officer.

"A few simple actions like keeping cool, staying hydrated, planning ahead and checking in with others can prevent serious illness."

Drink water regularly on very hot days, even before you feel thirsty, especially if you’re outdoors or being active.

Look out for signs of dehydration, including thirst, lightheadedness, dry mouth, tiredness, dark, strong-smelling urine, or passing less urine than usual.

If your doctor normally advises you to limit fluids, ask them how much you should drink during hot weather.

Use air conditioning or a fan, wear light and loose-fitting clothing, keep your skin wet (for example, with a spray bottle or damp sponge), and take cool showers or foot baths.

Close blinds or curtains to block heat from entering your home and if you need to head out, spend time in cool places such as air-conditioned buildings.

Check the weather forecast and Bureau of Meteorology heatwave warnings regularly.

If the hottest part of the day is coming, avoid outdoor work or exercise and reschedule strenuous activities to a cooler time.

"A quick call can make a big difference" Dr McElnay said.

"Check in on older people, friends, neighbours, and anyone who might need support on hot days."

People most at risk include those over 65, pregnant women, babies and young children, people with acute or chronic health problems, people who are socially isolated, and people with limited ways to keep cool (such as without air conditioning or living in buildings that heat up easily).
