Inside Health

Covid and other bugs have ripped through the Inside Health team, so we find out why everyone seems to be getting sick at the moment and if we will be facing a torrent of infections for months or even years to come. We see how easy it is to buy antibiotics online and why scientists are worried about it. And can ketamine and its mind-altering powers can help free people from addiction to alcohol?

It’s January. Christmas is a distant memory and nobody feels much like getting off the sofa, but luckily this episode can help. James Gallagher is on a mission to find out what is the least amount of exercise you can do to still stay healthy. James goes on a Ramblers wellbeing walk, uses a treadmill for the first time and takes a hot bath all to find out how lazy he can be. His guide Dr Zoe Saynor at University of Portsmouth explains this is the question everyone asks and offers simple tips about how little you can do.Presenter: James Gallagher Producers: Gerry Holt and Erika Wright

James is in South Wales where he's wired up and locked inside a cryo-lab to discover the impact of cold on the human body. A temperature of 10C seems pretty mild doesn’t it - yet James is shocked at the profound stress it puts on his body. Today we discover why cold is a killer and what you can do about it if you’re struggling to heat your home.Presenter: James Gallagher Producer: Gerry Holt

Do you want to see your GP records at the touch of a button? That’s the plan in England, but doctors warn us freely opening them up to everyone is not safe. And we’ll explore a study that’s transforming our understanding of how cancers develop and bring clarity to the confusion around antidepressants after a study showed low serotonin levels were not the cause of depression.

Can you imagine moving out of the family home and watching your daughter grow up from a distance, all to avoid the threat of Covid? That’s the decision Shannon has taken because the drugs she takes for her lupus leave her immune system weak and vulnerable. She tells us what it’s been like shielding for 951 days (and counting) and we explore whether there are any solutions. Then we see why childhood vaccination rates have been falling for a decade and whether you should follow the health secretary’s example and share your antibiotics.Producer: Fiona Hill and Gerry Holt

I think I might’ve dodged Covid. Like many others, I’m fully vaccinated but have never tested positive despite having had plenty of opportunities to catch it. I used public transport to get to work during the lockdowns and was exposed to the virus when my son came down with it. So what’s going on? Armed with my covid antibody test results, I ask immunologist Prof Mala Maini to clear up the confusion. And a new scale to determine skin colour which could improve how certain health problems are diagnosed and treated.PRESENTER: James Gallagher PRODUCER: Beth Eastwood

Maybe listen to this one BEFORE you eat… James is off to meet the sewage scientists trying to stop the next pandemic. He meets the teams that were monitoring 80% of people’s faeces during Covid-19 and finds out how sewage led to hundreds of thousands of children having an emergency polio vaccine. James needs to collect a sample at a water treatment works and then head to the laboratory… just be glad you can’t smell a podcast. Presenter: James Gallagher Producer: Erika Wright

What do sweeteners do to our bodies? We force feed James cups of sweetened tea and find out with nutrition scientist Dr Sarah Berry from King’s College London. We then tackle something stronger - alcohol. Can a new supplement reduce the amount of alcohol getting into the body? And Rohin Francis gets frustrated at the shonky claims being made by health podcasts (not this one, of course, you’re totally in the right place).Presenter: James Gallagher Producer: Beth Eastwood

Should friends and family be trained to give potent medications to those dying at home to relieve their symptoms? We often say that we’d like to die peacefully at home when the inevitable happens. Yet people can be left in pain for hours waiting for a doctor or nurse to be free to visit and administer the medicines that ease our symptoms in our final days. James Gallagher speaks to Mark, who was trained to administer medicines to his mother to help keep her comfortable at the end of her life, and to palliative care doctor Marlise Poolman who is pioneering the programme across North Wales.Presenter: James Gallagher Producer: Beth Eastwood

Smitha Mundasad asks whether we will see waves of Covid – with infections going up and down and then up and down again - forever more. We speak to Elliot whose life has been transformed after a single shot of gene therapy to treat the inherited blood disorder haemophilia B. And Dr Margaret McCartney discusses the accidental discovery of Viagra and how sometimes researchers find new, surprising uses for old medicines.Produced by Geraldine Fitzgerald.
