As temperatures soar across the UK, health experts are warning of a growing risk of heat exhaustion. This common condition affects people of all ages and backgrounds when our bodies struggle to cool down in hot weather or during intense physical activity.
In an advisory issued by St John Ambulance, a leading first aid charity, BBC Medical Editor Fergus Walsh highlighted the crucial importance of recognising symptoms early on and seeking immediate care. According to NHS guidelines, this proactive approach is vital for preventing heat exhaustion from escalating into the more severe condition of heatstroke.
So how do you spot the signs? Look out for headaches, dizziness, and confusion, as well as loss of appetite and nausea. People affected may also experience excessive sweating, pale or clammy skin, muscle cramps in their arms, legs, and stomach, rapid breathing, a fast pulse, and a temperature above 38C. Children may become lethargic or floppy.
When heat exhaustion strikes, the priority is to cool down the person as quickly as possible. Move them to a cooler environment, ideally with air conditioning or in a shaded area outdoors. Help them lie down and elevate their feet slightly.
Rehydration is also essential for recovery. Encourage them to drink plenty of water, sports drinks, or rehydrate sachets. You can also cool the skin by spraying or sponging it with cool water, using a fan, or placing cold packs around the neck and armpits.
The NHS advises that if symptoms persist after 30 minutes, or worsen to include a temperature above 40C, confusion, seizures, or loss of consciousness, you must call for emergency assistance. Heatstroke is a medical emergency requiring urgent professional attention, so don't hesitate in seeking help. St John Ambulance and the NHS are in agreement that vulnerable groups – including older adults, young children, and those with chronic health conditions – should exercise particular caution.
