The Health Department is urging residents of Central Australia to take care with temperatures forecast to soar this week.
The region is experiencing one of its hottest starts to the year on record, with the temperature at Yulara near Uluru topping 40 degrees on all but two days this month.
Dr Stephen Gourley from the Alice Springs Hospital says it is essential people avoid over-exertion and drink plenty of fluids.
"Try to avoid the hottest part of the day between 10:00am and 2:00pm, avoid vigorous activity outdoors particular in that hot part of the day," he said.
He says tourists are particularly vulnerable.
"Where we find that people run into trouble are people who aren't familiar with the right things to do," he said.
"For example (they) try to walk around Ayers Rock in the middle of the day and get dehydrated."
