Welcome to summer. Over the next few months, we’ll endure heatwaves in different parts of the country. Extreme heat can be life-threatening for some people — and not necessarily the ones you expect.

Heat isn’t just unpleasant, it can be downright dangerous and everyone is at risk, even if you don’t think you’re particularly vulnerable.

When heatwave warnings are issued by the Bureau of Meteorology, it’s not simply based on reaching a certain temperature, like 40C.

The average daily temperate over a three-day period (which includes both the day and the night time) must be unusually hot for the location and the time of year.

The bureau also considers how those temperatures compare to conditions over the last 30 days in the area.

I know someone who was off work with heat stroke about a week ago.

This is a danger of Australia that is not normally told to tourists. Far more dangerous than most of the others. It can be deadly. I was hospitalised with heat stroke once, as a teenager.
