Light therapy sounds wholesome. Sit in front of a lamp. Feel better.

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.

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.

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 micro...

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 w...

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.

And why can cracking feel so strangely sa...

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 C...

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 Univ...

Introducing Strange Health, a new podcast from The Conversation.

Time and again, the health stories that go viral are the ones that make people recoil slightly before clicking anyway. Worms. Smells. Leaks. Stones. Toxins. The things you Google at midnight and hope nobody ever finds in your search history.
