Coventry researchers find ice baths make dippers eat more
Cold water swimming and ice baths have exploded in popularity in recent years, with proponents arguing their benefits for a range of phenomena, from burning extra calories, to improved mental health.
Prof Bloom led tests on their impact on appetite and food intake, along with PhD student Marie Grigg from Coventry University's Research Centre for Physical Activity, Sport and Exercise Sciences.The study involved 10 men and five women, who were all healthy and active, spending 30 minutes submerged in cold water, warm water, or sitting in a room at 26C, in tests carried out over several weeks.The researchers found those in the cold water - kept at a temperature of 16C - ate about 240 extra calories afterwards compared to those in 35C water or at room temperature."Ice baths and cold dips have become really popular; with many people hoping they'll help with weight loss," Prof Bloom said."Interestingly, people didn't say they felt hungrier during or after the cold water - they just ate more."Ms Grigg said more research was needed on the after-drop effect to determine whether repeated cold-water dunks could lead to long-term weight gain."Our findings show it is important to put strategies in place to avoid over-eating after cold water immersion," she added.

Mathieu van der Poel pulls out of Tour de France
Cyclist Mathieu van der Poel has been forced to abandon the Tour de France. His withdrawal is due to a diagnosis of pneumonia, following several days of cold-like symptoms that worsened. Van der Poel had enjoyed a strong Tour, twice taking the yellow jersey and securing victory on Stage 2. His team, Alpecin-Deceuninck, confirmed that his health is the top priority, requiring rest and recovery. This marks another setback for Alpecin-Deceuninck, who previously lost Jasper Philipsen to a crash.

Estelle Bingham wants you to know that manifesting isn't about wishing for outcomes – it's about healing
Estelle Bingham calls herself a heart-led healer. And though this job title will likely sound 'woo' to some, Bingham seems to commonly show up as the most practical person in the room, whatever the topic of conversation. She's calm yet direct, and discusses the harms we humans inflict on ourselves through self-doubt and negative self-talk as though they're obvious mistakes we've simply forgotten how to correct or avoid. After speaking with her, it does all feel a little more obvious. The idea that self love, self awareness, and gentle mindset shifts could change your life for the better seems like a no-brainer. But could it all be that easy? In recent years, these sorts of ideas have become wildly popular, particularly on social media. We have practitioners like Bingham to thank for the widespread adoption of techniques like 'positive self talk', journaling and manifestation mantras. But Bingham is careful to ascribe credit where it's due. She tells me that her family has used these techniques for generations and when we speak about her new book, Manifest Your True Essence, we discuss the cultural origins of practices like meditation and mindfulness. In a world full of TikTok mindset coaches offering questionable money manifestation courses, Bingham is the real deal. Her approach, which blends modern therapy and mindfulness with spirituality and mysticism, isn't about wishful thinking. It's about feeling your feelings, doing the work and transforming the parts of yourself you've been avoiding for too long. A framework for self love and success 'What I help people do is get out of their heads and into their hearts,' Bingham says. 'The heart has a wisdom of its own. Science has finally caught up with what wisdom keepers or shamans or mystical people have known for centuries.' Her book Manifesting Your True Essence: Clear Your Blocks, Find Your Joy, Live Your Truth is a toolkit for self acceptance. Each chapter aims to help readers understand what's holding them back in life and learn how to love themselves, offering useful exercises and meditations that encourage us to find confidence and compassion where it might be lacking. The homework isn't always easy, as I found when I started reading the book. At times, the things you're encouraged to think about will make you feel uncomfortable, but for Bingham, 'feel' is the operative word. 'Instead of thinking about healing, we are feeling healing,' she explains. 'When we feel our healing, then it's no longer intellectualised. It's happening in real time, and that's why it's so successful.' Before her career as a Goop favourite and mindset expert to the stars, Bingham worked in TV and radio – something she enjoyed but never truly felt aligned with. She tells me that she's always been able to see where people's strengths lie and that some of her friends and clients today were people she saw a spark in decades ago. ' Charlotte Tilbury and I have been friends for years, since we were teenagers, and one of the things I knew intuitively about Charlotte was that she would succeed. She really embraced that idea completely and utterly, with every cell of her body. And I saw it in her.' she says. That self-belief – and the blocks that often stand in its way – is a central part of Estelle's one-to-one work. 'A lot of us have a voice in our heads that says, 'You can't do that. I don't believe in you.' It pulls us down. It's there when we're waking up, in our quietest moments, or when we're about to start something new. I realised I needed to help people shift their mindset – to help them move into the unconscious and pick apart that negative voice,' she explains. The phone call from Gwyneth Paltrow came before Estelle even had a website. 'She was coming to do an In Goop Health summit in London. They'd heard about me, and she said she'd been looking for me,' Estelle recalls. 'I always say, the proof of the pudding is in the eating. If you're doing something well, word gets out.' Beyond the TikTok manifestation coaches But with mindset work and manifestation now booming on TikTok and Instagram, the nuance of these practices is often diluted and exploited – sometimes to the detriment of people in vulnerable positions. There's a danger, Estelle says, in turning ancient practices into 'life hacks'. 'Ultimately, it's great that people are waking up to the idea that they're powerful – I really love that. Because I completely, wholeheartedly believe that we all have that power,' she says. 'But it gets tricky when we're manifesting from the head, based on things we think we want, instead of the heart. I'm not saying you shouldn't want to manifest a relationship or a better job. But you might not be able to love, or feel safe in that job, because of something stuck deep in your unconscious. That needs to be understood and alchemised. It needs to be transformed in order for you to actually receive, and not sabotage it.' The real work, she says, isn't about wishing for outcomes, but getting to know yourself deeply enough that joy, connection and self-worth aren't dependent on external circumstances. 'When we manifest from our hearts rather than our heads, it's a little bit deeper – it's sort of a master manifestation. The more you know about yourself, the more powerful you are in your own life. Happiness isn't outside of us. It's something inside of us. And when you manifest with understanding, openness or curiosity, life brings you everything you need.' So how does someone begin? The social media version of manifestation often looks deceptively easy – a vision board, a candle, a single thought repeated enough times to become reality. 'I wrote the book so people could start the process of healing and self-discovery and empowerment. To go on that journey of deep, proper self love. Because that's what manifestation really is – it's what radical self-love looks like,' Estelle says. 'When we meet the parts of us that have been hurt – with love, curiosity and compassion – it can feel overwhelming. But it's the greatest gift. You'll be amazed when you gather together the parts you've pushed away. The ones you didn't want to look at. When you bring them in from the cold, you'll be so excited and wowed by how beautiful they are. Because that's your true essence.' Self belief in a time of crisis Bingham's philosophy is gaining traction at a time where mental health services are stretched, and loneliness is widespread. 'The loneliness epidemic is worldwide,' she says. 'The way we are online all the time, always on our devices – it's doing us damage.' She's been working with the charity Body & Soul for over a decade in an attempt to share her philosophies with those who need it most. This is refreshing at a time where so many esoteric practices are whitewashed and repackaged as money-making schemes. 'I've been doing one-to-ones, workshops, working with the team. We just need more spaces where people can talk, connect, and allow feelings to flow,' she explains. But for those who are sceptical of too much talk of feelings, or of concepts like the power of positive thoughts, Estelle is keen to open up a dialogue. 'For millennia, there's been this push-pull with people who can't quite get their heads around these ideas. And that's okay. But some of these things are basic. My work intersects with neurology and the study of the heart's connection to the brain – how our beliefs, feelings and reactions shape who we are and who we want to be.' Her book makes reference to several fascinating pieces of modern research that point to the tangible benefits of practices like mindfulness and meditation. Estelle Bingham's wellbeing rituals I'm keen to discuss the benefits of transcendental meditation with Estelle, having learned that she began practicing aged six. So she tells me about her routine. 'I start my days with some organic matcha and I set an intention every morning. I meditate. I learned transcendental meditation when I was very young – but it's basically just mantra-based meditation. And I move. I go to the gym or take the dog for a walk. I spend a lot of time inside, so I try to get out, even if it's just to walk around the park with some music.' You don't need to be still, she adds, to shift your state. 'Walking can take your brain waves from beta to alpha and theta. You don't need silence – you just need awareness.' A mindset shift can feel a long way off for most people. But, she explains, it's all about habit formation. She tells me there are three things you can do every day that are simple and accessible to everyone. 'Just take a couple of minutes a day to meditate. Breathe into your heart. Listen to what your heart is telling you – it will guide you. 'Hold both hands on your heart, breathe in through the nose, out through the mouth, and ask, 'How are you today?' The heart will tell you. And then write it down. Journaling is still such an amazing tool. Just breathing, heart connection and journaling – it's a great place to start.' Her book is designed to be used intuitively. 'You can dip into chapters, flip to the right meditation or journal prompt when you feel triggered, and use it as a tool. I wrote it with the ups and downs of life in mind,' she says. Because life, like healing, is a process. As Bingham explains, 'there's a beginning, a middle and an end to every piece of healing. It's like a bridge, to get to the other side, you have to start.'

Bristol doctor Tony Dixon falsified mesh notes, medical hearing finds
A surgeon found to have left patients in agony after using artificial mesh to treat prolapsed bowels has been found to have falsified medical Dixon was suspended after the surgery was found to have caused harm to hundreds of patients at two hospitals in a new hearing has examined Dr Dixon's records and found he dishonestly created patient records long after he was involved in their mesh patient Jill Smith, from Westbury-on-Trym in Bristol, said Mr Dixon "should never work again". Mr Dixon said he "has very many satisfied patients but respects the findings of the tribunal". He also apologises to those he may have let down. A spokesperson for Mr Dixon added: "Mr Dixon has disputed the allegations throughout the tribunal hearing and is disappointed by the factual determination."Mr Dixon has always endeavoured to provide the highest standard of care to his patients." Mrs Smith, 71, has received a settlement from Mr Dixon after paying privately to have a fisher operation but she claims she ended up having three meshes implanted without her consent which left her in severe pain and suffering from breakdowns. She told the BBC that her own experience meant she was not surprised the tribunal had found dishonesty, adding: "It's just he is saying one thing and writing something else and you just feel a bit strange about it all, that it's corrupt and lying."It makes people feel, me as well, disappointed, disillusioned."Two investigations at Southmead Hospital and Spire Bristol have previously found Mr Dixon caused harm to hundreds of people by carrying out operations that were not has since said private hospitals now can access patient notes without having to rely on copies from consultants. The tribunal had examined claims medical records for seven patients contained false information and were not created at the correct found that as part of a Spire review, Mr Dixon disclosed medical records for several patients that were created after his involvement in their care. It found his actions would have given the false impression that the Spire records were also found patient records disclosed to the solicitors of four patients who were suing him contained false Dixon was also found to have failed to adequately explain the complications of a re-look laparotomy in 2017.A final decision over what sanctions will be taken against Mr Dixon is expected this summer. Dr Dixon had previously built up an international reputation as the go-to expert for patients with prolapsed used a technique known as mesh rectopexy to treat bowel the procedure, mesh implants are placed into the body to treat pelvic organ prolapse which can occur after mesh, which is usually made from synthetic polypropylene, is intended to repair damaged or weakened the point of his suspension in 2024, the Medical Practitioners Tribunal Service (MPTS) said Dr Dixon's "misconduct was so serious that action needed be taken to protect members of the public".But, the tribunal considered that a longer period of suspension would be unduly punitive, especially taking into account the period that Dr Dixon had already been the subject of fitness to practise Southmead Hospital and Spire Bristol apologised to victims after his suspension.
