Vampires and werewolves and zombies, oh my! Where did all these monsters come from?
Undiagnosed medical conditions might have fuelled the mythology behind some of these creatures.
Norman and Tegan delve into why vampires drink blood, why werewolves howl at the full moon and how a hex might have its intended effect.

It’s hay fever season, and as you sniffle away next to an air purifier, you might be wondering why we haven’t cured such a common ailment.
Allergic rhinitis, as it’s scientifically known, has plagued people for generations. It's thought up to 24 per cent of Australians suffer from it.
Norman and Tegan run through what hay fever is, how we identified it and what can be done to treat it.

Many of us are disconnected from nature – we live in cities, work in offices, exercise indoors.
There is a hypothesis that our disconnection from the earth itself – the ground – is causing a range of illnesses.
But the people selling this hypothesis are also trying to sell you a range of expensive products.
Norman and Tegan debunk a pseudoscience that has been gaining traction.

Monosodium glutamate (MSG) is a flavour enhancer that often gets a bad wrap.
You might know someone who swears it makes them sick, or you yourself might steer clear of foods unless they have that 'no added MSG' label.
Norman and Tegan explain why the bad PR around MSG has more to do with shonky research and misconceptions than the ingredient itself.

If you've found yourself in a particular corner of health and wellness TikTok, chances are you've heard all about cortisol.
Influencers might be urging you to massage your face, stuff your mouth full of dates and even supplement your diet with sea moss.

If you've ever complained about a bad night's sleep, you might've been urged to take melatonin.
It's a hormone our bodies naturally produce, and also a supplement that many claim can cure insomnia and leave you better rested.
But Norman and Tegan tuck into all the reasons we shouldn't be taking melatonin lightly.

In some parts of the world sauna bathing is a daily activity.
In Finland, it would even be rude to deny an invitation to get hot and sweaty with a business associate.
As well as being culturally significant, the sauna has many touted health benefits – from protecting against cardiovascular disease, to fending off cognitive decline.
Norman and Tegan sort through the evidence.

Norman went for the plunge – and lived to tell Tegan the tale.
