Why am I so lethargic in the heat?
Does very hot weather leave you feeling more exhausted and lethargic than usual? There might be an initial surge of joy when the sun finally comes out – but once temperatures really creep up, we can end up feeling physically drained, wondering whether we should follow the Mediterranean’s lead and start introducing daily siestas. So, why does hot weather make us so tired? We asked a doctor to explain… Bodies have to work harder in the heat“When the weather is hot, our bodies have to work harder to cool themselves down,” says Dr Zulqarnain Shah, medical director at SSP Health and GP at SSP Health practice Colne Road Surgery. “The body’s natural cooling mechanism involves increasing blood circulation near the skin’s surface and promoting sweat production. These physiological changes can lead to fatigue and a feeling of lethargy. It is essential to recognise that this fatigue is a normal response to heat and is typically temporary.” Dehydration Low energy and tiredness are also common when you’re lacking hydration. “Hot weather increases the rate of fluid loss through sweating, leading to dehydration. Dehydration can contribute to fatigue and make you feel even more lethargic,” adds Dr Shah. “To avoid this, it’s important to stay adequately hydrated by drinking plenty of fluids, especially water. Aim to drink even when you’re not feeling thirsty, as thirst is not always an accurate indicator of dehydration.” Heat exhaustion “Prolonged exposure to heat can result in heat exhaustion, a condition characterised by symptoms such as heavy sweating, weakness, dizziness, nausea, headache, and muscle cramps. If you experience these warning signs, it’s crucial to move to a cooler environment, drink fluids, and rest. If symptoms persist or worsen, seek medical attention promptly,” says Shah. It’s important to pay attention to warning signs, as if heat stroke develops, this is a medical emergency. Shah stresses: “Heat stroke is a severe and potentially life-threatening condition that requires immediate medical intervention. It occurs when the body’s temperature regulation fails, and the core temperature rises dangerously high. “Symptoms may include a high body temperature (above 39.4°C), altered mental state, confusion, rapid breathing, rapid heartbeat, and even loss of consciousness. If you suspect heat stroke, call emergency services immediately.” Sleep deprivation The extra tiredness could also be linked to poor sleep, as this can really suffer in the heat. “Hot temperatures can disrupt sleep and lead to poor sleep quality. The body needs to cool down to initiate sleep, and excessive heat can make it difficult to reach the optimal sleep temperature,” explains Shah. “To improve sleep in hot weather, consider using fans or air conditioning, wearing lightweight and breathable sleepwear, keeping your bedroom well-ventilated, and using lighter bedding.” Pre-existing conditions could get worse Many people living with chronic or long-term health conditions deal with fatigue – which may flare up during heatwaves. “Hot weather can exacerbate symptoms and increase fatigue in individuals with certain chronic health conditions. Conditions such as heart disease, kidney problems, and respiratory issues can be particularly sensitive to heat,” notes Shah. “It’s vital to be aware of your specific health condition and consult with your healthcare provider for personalised advice on managing your symptoms during hot weather. They may recommend staying in cooler environments, adjusting medications, or monitoring your fluid intake more closely.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live 8 tips for surviving Glastonbury with kids David Beckham designs new car collection with Maserati The dos and don’ts of looking after your garden in a heatwave

Samantha Womack ‘would have delayed’ cancer treatment to strike with NHS staff
Samantha Womack has said she would’ve delayed her own cancer treatment in solidarity with striking NHS staff who “shouldn’t be eating from food banks”. The former EastEnders actor, 50, announced she had been diagnosed with “brutal” breast cancer in August last year – shortly after Dame Olivia Newton-John died from the disease. Last December, NHS doctors and nurses went on a nationwide strike demanding better pay amid a cost-of-living crisis and rising inflation. Describing herself as a “huge advocate” of England’s national health service, she called it “one of the best gifts we have” in an interview with Press Association. She added: “But when you’ve got the people who are working as hard as they are doing the hours they are, not being supported, even if it would have delayed my own personal treatment, “I would have been out there fighting with them, because I’m absolutely desperate for them to be paid properly and appropriately for what they do,” she continued. “They certainly shouldn’t be eating from food banks.” She also told the agency Newton-John’s death made Womack want to share her own diagnosis, “because I thought everyone knows someone that’s got cancer”. “It was very poignant for me when I got my diagnosis that she had lost her battle and they happened within the same timeframe,” she explained. Womack, who played Ronnie Mitchell on the hit BBC soap until 2017, told fans in January 2023 that she had overcome breast cancer. The British actor is now lending her support to a campaign enabling greater access to a new AI breast cancer diagnostic tool called Digistain. The UK’s first breast cancer risk profiling solution, Digistain helps patients better understand their cancer and the specific treatment that will most benefit them. Womack said she didn’t know about Digistain when her cancer was diagnosed, and that she was “anxious not to have chemotherapy” if she didn’t require the “brutal treatment”. “I knew that there was a test called the Oncotype test, which is very similar....(but) it’s incredibly expensive so it’s just not available to most people,” she added. Womack said the test gives a ratio of how beneficial chemotherapy would be and she was “on the fence” so had two rounds before making the decision to stop. Last October, Womack gave fans a health update while receiving the treatment, explaining that she had gotten her appetite back but was struggling with migraines. Elsewhere in the interview on Friday (12 May), Womack reflected on life after being given the all-clear and how it has changed her perspective. “It’s apparent in every little thing that you think,” she continued. “It’s a bit like learning to think and speak in a different language and it’s quite exhausting, because you’re not quite the same person that you were so everything is just slightly shaded in a different colour.” Read More Rainy bike rides and jellybean bribes: The secrets of royal coronation photographer Hugo Burnand Taylor Swift fans react to new photo ‘confirming’ Matty Healy romance: ‘I’m going to cry’ The Bear star Jeremy Allen White’s wife Addison Timlin reportedly files for divorce Meghan is ‘cuckoo’ in royal nest and her ‘woke hang-ups’ will destroy marriage, says Labour grandee Robert De Niro reveals name of newborn daughter as he shares first photo of seventh child

Max Verstappen pips Oscar Piastri to pole after tense qualifying for Japanese GP
Max Verstappen set a blistering pace to blow away the challenge of Oscar Piastri and Lando Norris and take pole position for the Japanese Grand Prix. Verstappen’s record 10-race winning run and Red Bull’s unbeaten season came to an end in Singapore last weekend. The Dutchman topped all three practice sessions at Suzuka to suggest the Milton Keynes-based team had banished the issues that they experienced in the city-state. And Verstappen was imperious around the high-speed corner circuit – where Lewis Hamilton warned the Red Bull would be “phenomenal” – taking pole by a massive 0.581 seconds ahead of Piastri. Norris had narrowed the gap to Verstappen, who is closing in on a hat-trick of world titles, in final practice to raise hope of a challenge for pole. But Verstappen was dominant in the final qualifying session on brand new tyres, blowing away the competition from the two McLarens. “Incredible weekend so far, especially in qualifying when you can push it to the limit. It felt really nice,” Verstappen said on track. “We had a bad weekend in Singapore. I felt this was going to be a good track. From lap one it has been really nice.” Piastri, in his debut season in Formula One, had never even been to Japan before this week but got the edge on his McLaren team-mate to line up on the front row. Red Bull will almost certainly clinch the Constructors’ Championship on Sunday at the home race of their engine supplier Honda. Verstappen’s team-mate Sergio Perez finished fifth, over seven tenths adrift of the pace-setter. Hamilton and George Russell were well off the pace for Mercedes, who are battling with Ferrari to finish second in the Constructors’ Championship, and will line up seventh and eighth on the grid. Ferrari, who are running a new floor at Suzuka, took fourth via Charles Leclerc, while Singapore-winner Carlos Sainz finished sixth. Yuki Tsunoda was confirmed by AlphaTauri to be driving alongside Daniel Ricciardo in 2024 and delighted his home crowd by making the top-10 shootout, finishing ninth. Q1 was red-flagged with just over nine minutes remaining when Williams’ Logan Sargeant oversteered out of the final corner and slid heavily into the barriers. The American, who is yet to be confirmed by Williams for 2024, quickly jumped out of the car and made his way across the track and back to the pit lane. Williams Team Principal James Vowles told Sky Sports: “It is heartbreaking for Logan.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Lando Norris narrows gap on Max Verstappen at final practice in Japan Max Verstappen returns to form in Japanese Grand Prix practice Lance Stroll to sit out Singapore Grand Prix after huge crash in qualifying
