After the hottest June in history and record-breaking temperatures last year, the UK is really feeling the heat. But, we’re not alone. Last week the world experienced the hottest day in history - and forecasters warn this is just a taste of what is to come.   Here on Inside Health we love a tricky question - so in the first episode of the new series we’re chasing down the answer to a pretty timely one, how hot is too hot for our health.  James heads into the lab to explore exactly what is going on inside our bodies when it gets hotter. He gets wired up and locked inside a heated chamber to find out what factors matter most, from core temperature to humidity, and learns which is more deadly, cold or heat. He also hears about a surprising tip to stay safe in the heat.  Do join us on what promises to be a rather hot and sweaty journey…

Last month, Catherine, Princess of Wales shared she’d been diagnosed with cancer. Describing this news as ‘a huge shock’ and at age just 42, the Princess’ disease falls into a category known as “early-onset cancer” – when the disease affects those under 50. While cases in this age group are still rare, diagnosis rates over the past few years have been growing. And scientists are now on a mission to figure out why.  Receiving a cancer diagnosis at any age is devastating, but younger people living with the disease face additional challenges. James Gallagher talks to Emma Campbell, a mum of three young children who was diagnosed with bowel cancer at 36. Emma shares not just how her treatment affected her life, but the difficulties in advocating for herself as a younger person trying to get diagnosed. Professor Helen Coleman, cancer epidemiologist for Queens University Belfast, has been studying these diagnostic rates in younger people and explains possible reasons why more people like Emma are finding themselves living with the disease.  A series of videos recently went viral on social media from women claiming their weight loss drugs got them pregnant. These drugs – like Ozempic and Wegovy – help people lose weight by suppressing appetite, but could they impact fertility? James speaks to Dr Charlotte Moffett, lecturer in Pharmacology and Molecular Pathology at the University of Ulster, who is studying if these drugs might alter someone's ability to conceive. James is also joined in the studio by GP, Dr Margaret McCartney, who helps him answer some of your questions.  Presenter: James Gallagher

How did you sleep last night?  Perhaps you couldn't drift off, or maybe you woke in the middle of the night and then couldn't nod off again. In this special edition of Inside Health we're talking all about insomnia. It’s an issue that may affect many of us at some point in our lives – but for some it goes beyond a short period of not being able to sleep and becomes something more serious. You’ve been getting in touch with your questions, and James is joined by a trio of experts ready to answer to them: Dr Allie Hare, president of the British Sleep Society and consultant physician in sleep medicine at the Royal Brompton Hospital, Colin Espie, a professor of sleep medicine at Oxford University and Dr Faith Orchard, a lecturer in psychology at Sussex University. We’re going to find out why we get insomnia, when to seek help and how much factors like ageing, menopause, needing the loo or shift work matter. And we'll look at the latest advice and treatments. Can insomnia be fixed?  You can keep in touch with the team by emailing insidehealth@bbc.co.uk Presenter: James Gallagher

Scientists are worried about ticks.  They say they’re starting to pose more of a health risk here in the UK, as our climate warms and urban areas spill into green spaces.  But what are ticks, what kind of disease can they cause – and how much of a problem are they? We go on a tick hunt in Richmond Park and then head back to the lab to meet the ticks we’ve collected. We find out why new species of ticks and new diseases could be coming our way - and what you can do to keep safe. Also this week, we answer your questions on the impact of noise on our health following our recent programme.  And we delve into the fascinating world of measles. It’s the most contagious virus in the world – by a long way. What is it about this virus that makes it so spectacularly good at infecting us?

We go on a tick hunt

Have you ever tried intermittent fasting? As the month of Ramadan comes to an end, many Muslims are concluding several weeks of time-restricted eating. But outside of religion, many of us are now choosing to eat this way for health reasons – even UK PM Rishi Sunak does a weekly fast. Claimed benefits of intermittent fasting range from weight loss to improved immune function to maybe even living longer, but do these stack up?   James Gallagher gives one of these popular diets a go whilst trying to answer if restricting when we eat our food is good for us. He chats to Colin Selman from the University of Glasgow about the animal studies which inspired these claims, Claudia Langenberg from Queen Mary University on what happens in our bodies when fasting, and Lucy Serpell from UCL on the potential dangers these types of diets can pose. Plus, we visit AFC Wimbledon for an Iftar event to hear if people fasting during Ramadan experience any changes to their health.   Presenter: James Gallagher

From ear-splitting aircraft noise and the drone of traffic to the hum of an open-plan office, the world around us can feel loud.  But is it getting louder? And is this having any effect on our health - and even on how long we live?  We find out when living close to a road, railway or airport might go from nuisance to health hazard, with potential effects on our sleep, heart health, mood and concentration.  It’ll get loud as we do some tests in a lab to explore how unwanted sound might affect the rest of the body beyond our ears, and we sift through the growing research on the impact of noise. Who might be most at risk and why?  We also find out why our reaction to noise might be about more than just volume - and we go in search of some simple tips to help.
