Doctors are urging Victorians to stay cool and take cover as the state faces a heat wave in coming days.
Australian Medical Association Victoria President Dr Harry Hemley said Victorians may need to modify their routines during the heat wave to avoid heat exhaustion and dehydration.
Temperatures are tipped to soar to 41 degrees in parts of the state over the next few days.
"Try to stay indoors to keep cool. If you do venture out into the heat, stay in the shade and make sure you're prepared with long sleeves, a broad-rimmed hat, sunglasses and sunscreen," he said in a statement on Saturday.
"In these prolonged periods of heat it's important that you listen to your body - drink plenty of water and if you feel dizzy, take a rest.

"Don't exercise too strenuously, particularly if your fitness levels are low. Even if you're fit, active and athletic, you are still at risk of heat stroke. Early morning and late evening are good times to exercise if you can't move your routine indoors."
Dr Hemley said hospital admissions increased in extreme heat, particularly among the elderly and children, who were more prone to heat stroke and fluid loss.
"Children should be encouraged to wear a hat and carry a bottle of water, as well as keeping out of the sun," he said.
"Temperatures in vehicles will be much higher than outdoors, so never leave children, or pets, unattended in cars, not even for a few minutes.
""Elderly people on medications such as fluid tablets have less flexibility in their system to deal with the pressures of dehydration so it is very important they keep adequately hydrated."
Dr Hemley said a time of adversity provided a great opportunity for neighbours to get to know each other.
"If you've got a pool, why not invite the neighbours to come around?
"If we all use common sense and look after each other, we'll be able to stay as healthy as possible."
