With the weather this week being hot, hot, hot it is really important to be able to recognise the signs and symptoms of heat exhaustion so you can stop it from developing into heat stroke.
If left untreated the body temperature will continue to rise and the person will quickly develop into heat stroke where the brain is starting to overheat.

If I suspect heat exhaustion what should I do?
If you suspect that someone has started to develop heat exhaustion move them out of the direct sunlight into a cooler, well ventilated area.
Give them some cool fluids to drink and keep the room well ventilated. Small children are particularly at risk of developing heat exhaustion so take care in the sun and make sure they are well hydrated. Offer extra fluids throughout the day and keep an eye on their urine output.
