Drink plenty of water, wear sunscreen, keep covered and drink responsibly.
That's the advice being given to Melburnians as they deal with an extended period of extreme heat.
Victorian paramedics say unrelenting heat drains people of energy and they should be especially vigilant in protecting the elderly and children.
Ambulance Victoria emergency manager Justin Dunlop said people should avoid exercise, not leave children in cars, turn airconditioners on and keep hydrated.
For those going away, be prepared for emergencies by making sure mobile phones are working.
He also urged people not to ignore the symptoms of heatstroke.
The early signs of heatstroke include feeling drained of energy and pale and sweaty skin.
It can also include headaches, nausea and vomiting.
