Heat Exhaustion First Aid

Heat Exhaustion


It’s the middle of summer, which means the chances of succumbing to heat exhaustion are higher than ever! 

Heat exhaustion is caused due to a large loss of salt and water from the body, usually due to excessive sweating. Those that aren’t used to the heat and humidity, those that are already unwell and elderly people are the most at risk.


Heat Exhaustion First Aid Accident & Emergency

Look for the symptoms of heat exhaustion.



Heat exhaustion takes awhile to take effect as more and more salt and water is lost from the body. Common symptoms of people that have lost too much include: 

  • A headache
  • Dizziness and confusion
  • Loss of appetite and feeling sick
  • Sweating with pale clammy skin
  • Cramps in the arms, legs and stomach
  • Fast, weakening pulse and shallow breathing



  • Help take the patient to a cool place and get them to lie down with their legs raised.
  • Give them water. You can also give them a sports drink or an oral rehydration solution to help replace the salt and fluid they have lost by sweating.
  • Keep checking their breathing, pulse and level of response.
  • Even if they recover quickly, suggest they see a doctor.
  • If they seem to be getting worse, place them into the recovery position and call 000 for an ambulance.
