A TV doctor has shared the five symptoms of heatstroke to look out for.
Dr Chris Steele appeared on This Morning today, where he shared some things to look out for amid the growing temperatures across the UK, with the UK's temperature record possibly "obliterated" with sweltering highs of 43 degrees centigrade predicted.
Heatstroke is described as when the body can no longer control its own temperature. If untreated, it can be life-threatening and can cause damage to your brain or other vital organs, and is one of the most dangerous heat-related illnesses.
Dr Chris has now shared a list of symptoms to look out for in these soaring temperatures.
Speaking on the ITV show, he said: "First of all, there's heat exhaustion. That's a condition where you feel very hot but you're sweating profusely. You have pale clammy skin and you have a fast pulse and rapid breathing, headaches, maybe dizziness and confusion."
"If you have those symptoms and you're trying to treat them, and you have them for thirty minutes or more, you might be going into heatstroke," he went on to add.
"Heatstroke is a life threatening condition, and I'll go through the symptoms, but if heatstroke strikes you, that's a 999 call."
Dr Chris then went on to share the symptoms to look out for, which includes your body temperature rising, dizziness and confusion or an increase in the breathing as it becomes more rapid.
He also said that not sweating is a symptom to look out for, and that retaining fluid in the body can also be "very uncomfortable". An extreme symptom can also be the person having a seizure or a fit.
Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, has urged people to be careful in the hot weather.
He said: "We want everyone to enjoy the hot weather when it arrives, but also to check in on their vulnerable family, friends and neighbours to make sure they are prepared for the warm conditions ahead.
"High temperatures are predicted for a prolonged period, so make sure to follow our simple health advice to beat the heat."
