Which hair loss treatments actually work?

Hair loss is common, but there are many different causes and potentially many different treatments. From topical ointments to light therapy, to scalp massage routines. What works to slow, or even reverse, hair loss? Norman and Tegan comb through the evidence for approved treatments and too-good-to-be-true snake oil.

Can functional mushrooms really help treat cancer?

The use of mushrooms in medicine goes back centuries, but there’s still a lot to learn about the bioactive compounds in fungi. There are many claims surrounding 'functional mushrooms' – types of mushrooms thought to have medicinal properties beyond simple nutrition. These include lion’s mane, reishi, cordyceps, shiitake and turkey tail. Norman and Tegan forage through the evidence for using mushrooms against cancer, to boost the immune system and to amplify cognition. We're doing a live show!

Why are people taping their mouths?

Depending on your corner of the internet, you might have seen people swearing by this new sleep hack, mouth taping. People claim they’re better rested, have better breath and stronger jawlines – all because they force themselves to breathe through their noses overnight. Norman and Tegan tackle this taping trend with an N=1 experiment, and a look at the relevant research. References: Mouth taping: a little less conversation, a little more action, please!

There's a lot of fog around brain fog

Unfortunately many more people have heard about brain fog because of the pandemic and long COVID. But the symptom was first mentioned centuries ago, and has been associated with dozens of conditions. Norman and Tegan try to define brain fog, and explain why it can be difficult to treat.

Why is everyone suddenly talking about seed oils?

It can be hard to keep up with food fads and diet trends (and spoiler: you don’t need to). But an intriguing assumption that has gained traction recently is that seed oils – think canola, sunflower, grapeseed – are terrible for you. Norman and Tegan unpack how that assumption has spread, and whether there’s any solid evidence to back it up.

Can you get away with skipping your daily shower?

January is an especially sweaty time in Australia, so maybe park this life change until the weather cools down… But is it necessary to bathe every day? As we learn more about the microbiome on our skin, more and more people are questioning their hygiene routine. Norman and Tegan sniff out the evidence for and against regular washing.

Should you base your diet on your blood type?

You might've heard of the blood type diet popularised in the 90s off the back of a best-selling book. It’s based on the theory that blood types emerged at different times in history, when our ancestors had very different diets. So does that mean certain foods are better for an A-, an AB+ or even an O-?As Norman and Tegan explain, it’s a complicated story.

Good way to keep up with what’s going on in Australia and round the works as well as latest research. As an Australian living overseas (Italy) I like to listen to it as it cuts through the noise.
