With temperatures climbing steadily as we head into what is predicted to be one of Australia’s hottest summers, we look at the signs of heat stroke you need to be aware of (and what you can do to keep yourself safe).
Heat stroke is a life-threatening condition where the body's temperature rises so much that your body stops sweating. The body loses its ability control temperature and if left untreated, heat stroke can cause damage to your vital organs included your brain, heart, kidneys and muscles.

Extreme heat can affect everyone, but older people, young children and people with chronic health conditions are most at risk. People taking certain medications, like blood-pressure lowing medications and antidepressants are also at risk.
