Imagine it's a typical summer's day and you've just heard predictions temperatures are set to top 45 degrees Celsius in some parts of Australia.
- An academic who studies the best way to cool down says a lot of public health advice about heatwaves is based on old wives' tales
- Most public health advice in Australia is similar, but some states offer some unusual tips
- Scientists hope to create evidence-based advice using a new sophisticated climate chamber
You turn down the air conditioner to 18 degrees, sit down with a salad and spend the day sucking on ice blocks.
Well, according to science, none of these things are the best way to cool down in a heatwave, yet they are among the recommendations made by Australia's public health authorities.
That's not to say turning on the air-conditioner is wrong, Professor of Thermoregulatory Physiology Ollie Jay says.
Professor Jay and his team at the University of Sydney study the best ways to cool down.
