Hyperthermia / heat exhaustion - stay safe this summer

Welcoming all of our past, present and future first aid attendees, may your 2021 be a safe one for all.    A timely reminder to stay cool and avoid heat related illnesses 

What is hyperthermia? 

Hyperthermia may be caused by excessive heat absorption from a hot environment, excessive heat production from metabolic activity, failure of the cooling mechanisms, or an alteration in the body’s set temperature. Hyperthermia can lead to heat exhaustion and heat stroke. 

What is dehydration and how do you manage it? 

Dehydration happens when fluid intake does not equal perspiration loss. The casualty has a clammy skin, weak pulse and is nauseous, dizzy and anxious. Replace fluids by encouraging them to drink water, juice, or sports drinks. You should seek medical help if symptoms get worse or don’t improve within 24 hours, the casualty is elderly or an infant, or if you think a prescription medication caused the dehydration. 

What is heat exhaustion and how do you manage it? 

Heat exhaustion is when the body temperature rises beyond its normal core temperature but is still less than 40°C. Indications include fatigue associated with headache, nausea, vomiting, malaise, dizziness and possibly collapse. It is important to lie the casualty down, loosen and remove excessive clothing, moisten the skin with a moist cloth or atomiser spray, cool by fanning, give water to drink (only if fully conscious). Call EMS (dial triple zero, 000) and keep the casualty in the shade.
