Whether you’re away on holiday or lounging in the sun at home, needing a siesta after lunch or a disco nap before dinner on a hot summer’s day is normal. But how can you tell when warm weather-induced drowsiness is something more serious? We asked doctors to explain… What is heat exhaustion? “Prolonged exposure to the heat can cause heat exhaustion. It is the body’s response to excessive loss of water and salt,” says Dr Preethi Daniel, deputy medical director at London Doctors Clinic. “Symptoms may be characterised by heavy sweating, rapid breathing, headache, high temperature, nausea, a faster and weak pulse, light-headedness, feeling fatigued and heat cramps.” Older people, babies, children and those with chronic illnesses are much more likely to develop heat exhaustion. “Symptoms are usually the same in adults and children, and can make children tired and floppy,” says Dr Luke Powles, associate clinical director at Bupa Health Clinics. While not life-threatening, heat exhaustion is a warning sign that you need to cool down promptly to prevent progression to heat stroke, which means getting out of the sun immediately. “Remove any unnecessary clothing, lie down and raise your feet so they are above the level of your heart and drink plenty of water,” says Powles. “You can also use a cool sponge to cool your skin. Make sure someone stays with you until you feel a bit better – which you should do in half an hour or so.” If you don’t start to cool down after 30 minutes, see medical help, as you may have developed heatstroke. What is the difference between heat exhaustion and tiredness? “Heat exhaustion is the direct result of spending too much time in the sun and often raises your core body temperature to over 38 degrees, which isn’t an indicator of general tiredness,” says Dr Carolyn Barshall, GP at independent charitable hospital King Edward VII’s. “Whereas tiredness can be caused by many lifestyle factors such as disordered sleeping patterns, alcohol and poor diet.” Daniel adds: “If you have a lack of energy or aches and pains, consider it tiredness, but if you have any of the other symptoms mentioned above, it could be heat exhaustion.” What is heatstroke? “Heatstroke is the end result of overheating,” says Daniel. “Our internal temperature rises and creates confusion, drowsiness and can lead to seizures.” Much more serious than heat exhaustion, it can cause a change in mental status such as, Barshall says: “Confusion, delirium, combativeness, seizures, loss of consciousness, and a core body temperature above 40 degrees.” Symptoms may also include skin that’s not sweating even when it feels hot, fast breathing or shortness of breath. “Heat exhaustion and heatstroke are often confused, but there is a difference,” says Powles. “Heatstroke should be treated as an emergency, whereas with heat exhaustion, the person needs to be cooled down.” If you suspect someone has heatstroke you should call 999 or seek emergency help immediately. How to stay safe in the sun To prevent heat exhaustion during summer, it’s important not to spend too long in the sun and to stay hydrated. “Avoid direct sunlight between 11am and 3pm, and wear light-coloured, loose clothing,” says Daniel. “Drink plenty of cold drinks and water throughout the day and limit alcohol intake.” To help little ones, she says: “You can keep a pram or buggy cool by covering it with a damp cloth and refreshing it every 30 minutes.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live King Charles enjoys a wee dram at the Met Highland Gamesv Why have the birds disappeared from my garden?

Although most people have heard of sarcomas, research suggests the majority don’t really know what they are. A study by Sarcoma UK found 75% of people didn’t know what a sarcoma was – but there’s no better time than July’s Sarcoma Awareness Month to learn. Sarcomas are rare cancers that can either form in the bones or soft tissues that connect, support and surround other body structures and organs, explains Sarcoma UK. “If you’ve never heard of sarcoma before, you’re not alone,” says Dr Sorrel Bickley, director of research, policy and support at Sarcoma UK. “Sarcoma can affect any part of the body, on the inside or outside, including the muscle, bone, tendons, blood vessels and fatty tissues.” She says around 15 people are diagnosed with sarcoma cancer every day in the UK, and stresses: “It can affect anyone, at any age, and it’s vital that healthcare professionals can recognise its signs and symptoms.” During Sarcoma Awareness Month the charity is running a campaign called Does Size Matter?, in a bid to draw attention to the fact that a lump getting bigger is a key sign of sarcoma. “Most lumps and pains won’t be sarcomas, but it’s important to keep an eye on symptoms and to seek medical help if you’re worried,” stresses Bickley, who explains that many patients tell the charity it’s taken a long time for them to get a correct diagnosis. She adds: “Many people don’t consider their symptoms might be serious. Delays cost lives, and people have a better chance of surviving sarcoma if their cancer is diagnosed early. ” There are around 100 different subtypes of sarcoma, grouped into soft tissue sarcomas and bone sarcomas, and Bickley explains: “Soft tissue sarcomas may not have obvious symptoms in the early stages when the tumour is very small. The symptoms can become more obvious as the sarcoma grows, but this can depend on where in the body it’s found. ” She says there are several main sarcoma symptoms to be aware of… A lump that grows or changes Bickley says sarcoma is a “complicated cancer”, but the most common symptom is a lump, which could be anywhere on the body – including the arm or leg. “Most lumps aren’t harmful and a lump that isn’t getting bigger, isn’t causing any pain, or that has been there for a long time isn’t likely to be anything to worry about,” she says. “But if it’s growing quicky or measures more than five centimetres – about the size of a golf ball – then you should get it checked by your GP.” Swelling or pain in or around a bone Sarcoma cancer can also start in a bone – the most common symptoms are unexplained pain or tenderness around a bone, which may come and go and may be worse at night, explains Bickley. “If the pain is getting worse and doesn’t go away with rest or at night, you should go and see your GP to get it checked,” she advises. Stomach pain, feeling sick and loss of appetite Some forms of sarcoma – known as a gastrointestinal stromal tumours, or GISTs – can start in the gastrointestinal tract. “With this type of sarcoma, people most often experience symptoms like fatigue, anaemia, weight loss, feeling sick or discomfort around their stomach,” Bickley says. Blood in poo or vomit Noticing blood in your poo or vomit can also be a sign of a gastrointestinal stromal tumour, says Bickley, who adds: “There are lots of causes for blood in poo or vomit, but it needs to be checked by a medical professional.” For more information or advice about sarcoma, call the Sarcoma UK support line on 0808 801 0401, email supportline@sarcoma.org.uk, or text 07860 058830 to contact a specialist adviser.
