What is period scooping? And other menstrual hacks you should think twice about

Period scooping sounds like something you would only hear in a biology lab, not while doom-scrolling TikTok. Yet earlier this year, videos claiming you can “scoop out” your period to avoid the mess and shorten the whole thing racked up millions of views. In this episode, we hear from Sally King, a visiting fellow at King’s College London, about why you can't shorten your period, and why you need to be careful about upsetting the pH balance of your body. She also gives us her perspective as a menstrual physiologist on other period hacks, including menstrual blood face masks, and drinks that some influencers say can shorten your period. Strange Health is a podcast from The Conversation, an independent, not-for-profit news organisation.

What is the vagus nerve and can you really reset it?

The vagus nerve has become the internet’s favourite body part. On social media, it is everywhere. People hum into their phones, gargle with theatrical enthusiasm, dunk their faces into bowls of ice water and poke at their ears in the hope of “activating” it. So in this episode we focus our attention on the body’s longest cranial nerve and ask a simple question: what does the vagus nerve actually do, and can we really hack it? Hosts Katie Edwards and Dan Baumgardt turn this week to Arshad Majid, a professor of cerebrovascular neurology at the University of Sheffield and an expert in vagus nerve stimulation.

What your body odour says about you

Body odour has a reputation problem. It is often treated as a hygiene failure or a social offence. In reality, it is biology at work, plus a big helping of culture. And yet people online are trying chlorophyll shots to make their BO smell better. Hosts Katie Edwards and Dan Baumgardt discuss what evidence there is behind this, plus some of the health conditions that can affect body odour. And we talk to Mats Olsson, a professor of experimental psychology at the Karolinska Institutet in Stockholm, who studies how humans perceive body odour.

Does light therapy work? The science of stroboscopic stimulation

Light therapy sounds wholesome. Sit in front of a lamp. Feel better. But nowadays, it can also mean strapping on a flashing mask and watching your own brain generate kaleidoscopic hallucinations behind closed eyelids. In this episode, host Katie Edwards tries on a stroboscopic light mask being promoted by celebrities including Jennifer Aniston and Rosamund Pike to find out what happens. And David Schwartzman, a research fellow at the Sussex Centre for Consciousness Science at the University of Sussex, explains how stroboscopic light produces hallucinations in the brain, and how it's currently being trialled to treat conditions like depression.

Is detoxing your liver worth the hype?

Social media is full of green juices, charcoal supplements, foot patches and seven-day “liver resets”, all promising to purge the body of mysterious toxins and return it to a purer state. But do you really need to detox your liver? In the first episode of Strange Health, hosts Katie Edwards, a health editor at The Conversation, and Dan Baumgardt, a practising GP and lecturer in health and life sciences at the University of Bristol wince and occasionally laugh their way through some of the internet’s most popular detox trends. They also speak to Trish Lalor, a liver expert from the University of Birmingham, whose message is refreshingly blunt: “your body is really set up to do it by itself.” Strange Health is a podcast from The Conversation is an independent, not-for-profit news organisation.

Is cracking my neck and knuckles bad?

Joint cracking is one of those habits most of us acquire without thinking about it. In our third episode, we turn our attention to one of the body’s most common and least understood noises. Knuckles, backs, knees and necks all feature, along with the enduring warning many of us grew up with: “Stop cracking your joints, you’ll get arthritis.” Is there any truth in it? And why can cracking feel so strangely satisfying? Hosts Katie Edwards and Dan Baumgardt turn this week to Clodagh Toomey, a specialist in musculoskeletal injury and chronic lifestyle-related diseases such as osteoarthritis, to give you the science behind the myths.

Tonsils, kidneys and gall: why your body makes stones

The human body, it turns out, is surprisingly good at making stone. Give it enough time and the right conditions and it will go about crystallising minerals, hardening secretions and, in rare cases, turning tragedy into rock. Gallstones. Kidney stones. Tonsil stones. Salivary stones. And, in one of the strangest and saddest corners of medical history, stone babies. In our second episode, hosts Katie Edwards, a health editor at The Conversation, and Dan Baumgardt, a practising GP and lecturer in health and life sciences at the University of Bristol, take a tour through the stony side of human anatomy and ask why this keeps happening, where these stones form and which ones you actually need to worry about. They talk to Adam Taylor, a professor of anatomy at Lancaster University, who has spent years studying stones in both everyday and extraordinary contexts, including a rare genetic condition called alkaptonuria Strange Health is a podcast from The Conversation is an independent, not-for-profit news organisation.

Meet the mites that live on you: from demodex to dust mites and scabies

You are not alone in your own skin. Millions of microscopic creatures live there too. Our skin is home to entire ecosystems of microscopic life. Bacteria and fungi get most of the attention, but mites are there too. Among the most common are demodex mites, tiny eight-legged relatives of spiders that live inside hair follicles and pores, especially on the face. Almost all adults carry them. In this episode we explore what these microscopic housemates are actually doing on our bodies and why the idea of them can feel so unsettling. While demodex may be harmless, there are plenty of other mites that can cause problems, from dust mites, to scabies. Hosts Katie Edwards and Dan Baumgardt turn this week to Alejandra Perotti, professor of invertebrate biology at the University of Reading, who studies the relationship between mites and humans.

The pseudoscientific scale looksmaxxers use to rate each other

If you have teenagers in your life, they’ll probably have heard of the PSL scale. Or at least the language associated with it. Chad. Stacy. Normie. Subhuman. The PSL scale is a pseudoscientific attractiveness rating system used by looksmaxxers, men in a part of the manosphere who can go to extreme methods to change their appearance. The roots of this rating system lie in misogynistic online forums used by incels or involuntarily celibates, but now it’s all over social media. So how did the language of incels, and this one way of quantifying attractiveness and beauty, go so mainstream? In this episode, we speak to Jordan Foster, an associate professor of sociology at MacEwan University in Alberta, Canada, who researches social media, beauty and masculinity. He explains the origins of the PSL scale, where it fits into the manosphere, and how some looksmaxxing influencers are making money off it. This episode was written and produced by Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

The Making of One Nation: the unlikely rise of Australia’s Pauline Hanson

From a fish and chip shop in regional Queensland to the heart of Australian politics: this is the unlikely story of One Nation, Australia's most controversial minor party. For thirty years, One Nation and Pauline Hanson have been ridiculed, dismissed and shut out. Now, no one is laughing. This week we're running the first episode of The Making of One Nation, a new series from The Conversation hosted by Ashlynne McGhee. She explores how a party built on fear and grievance thrived, died and rose again to upend Australian politics. Hanson's infamous 1996 maiden speech to the Australian Senate — warning that Australia was "being swamped by Asians" — still echoes through Australian political life. But who was Pauline Hanson before she became a phenomenon, and what did she actually represent? Was she a cause of a new kind of politics, or a symptom of one already forming? We hear from Anna Broinowski, documentary maker and senior lecturer at the School of Art, Communication and English at the University of Sydney, who made a documentary and wrote a book about Hanson. Follow The Making of One Nation to make sure you don't miss more episodes in the coming weeks. Sign up here for a free daily newsletter from The Conversation.
