You might have seen those robot-looking red light masks being sold for skincare purposes.
You might have thought — looks technological, but does it work?
It's not just red light. There are a spectrum of health claims from infrared to ultraviolet.
Norman and Tegan go through the rainbow to assess where there's evidence, and where there's not.

These days, our mobile phones are rarely far away. Whether it’s in your hand, your pocket, or under your pillow at night.
Mobiles do emit radiation in order to connect to phone towers, which enables us to stay in contact with people and the internet.
But is that radiation doing us harm?
Norman and Tegan talk through the facts – what we do know, don’t know and suspect about our tech companions.

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.

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.
