Australia is predicted to experience a summer of severe heat due to the El Niño weather pattern1. Climate scientists have warned that Australia could be in for a summer of severe heat, with an increase in extremely hot days.

While some sun is necessary for vitamin D production, excessive exposure can lead to heat-related illnesses such as heatstroke2. Heatstroke is a condition caused by your body overheating – often because of prolonged exposure to or physical activity in very high temperatures – and it is the most serious form of heat injury.  

Call 000 immediately if you are experiencing heatstroke as it is considered a medical emergency.

Symptoms:2

  • Extremely high body temperature – core body temperature of 40º C (104º F) or higher
  • Altered mental state or behaviour (for example, confusion, slurred speech, irritability, delirium)
  • Dizziness
  • Loss of consciousness
  • Fast, strong pulse
  • Headache
  • Hot, red, dry or damp skin
  • Nausea and vomiting
  • Rapid breathing

Heatstroke prevention:3

  • Protect yourself against sunburn
  • Wear loose-fitting and lightweight clothing
  • Stay hydrated by drinking plenty of fluids
  • Be careful with certain medications that can affect your body’s ability to respond to heat and stay hydrated
  • Try to avoid strenuous activity during the hottest part of the day
  • Never stay or leave someone in a parked car during warm or hot weather

Treatment:4

  • Immediately move the person to a cooler place (into the shade or indoors)
  • Help lower the person’s body temperature with a cool bath or shower, or place ice packs or cold cloths/towels on their head, neck, armpits and groin
  • Give them sips of cool fluid if they are conscious (avoid alcohol and sugary drinks)
  • Remove the person’s excess clothing
