“Hot-cold, hot-cold is a really common thing,” Hannah Mary explains. “It improves your circulation and builds resilience. Swimming in cold water is really tough – with the cold shock you can focus on nothing else, it sharpens the mind and can become quite addictive.
“Sea swimming really helped us [during the pandemic]. Folk have adapted it into their lifestyle, and what we’re now doing is adding an extra element onto that, because it’s nice to have something warm and hot to go into.”
The health benefits are manifold, and it’s not hard to see why saunas are used so widely in Scandinavia: to unwind and forget the stresses of the working week, to socialise and even to hold business meetings.
Bringing a flavour of that to Shetland is a logical fit, Hannah Mary points out, noting the abundance of similarities – geological, scenic, cultural and social – between Scotland and Norway.
“Especially on the coasts, the people are very similar, and I think that reclaiming our relationship with nature is something we can learn a lot from Norwegians,” she says.
“Every weekend they head off to their huts, go and connect with nature in a way that we’ve kind of lost over the years.”
Hannah Mary and Callum are always keen to collaborate with other small businesses, including yoga instructors, mindfulness and meditation groups and sports clubs.
Haar Sauna’s maiden winter in the islands has turned out as well as they could have hoped so far: “We’re just delighted with how it has turned out, and how it’s been taken on by the local community, but also visitors to the islands as well – it’s just been phenomenal.”
Hannah Mary is quick to point out that none of this could be achieved without their hard-working employees on the ground: “We’ve got a few local staff now, and the business is growing.”
They intend to open a second sauna in Shetland later in 2024, which she describes as “very exciting”.
“It’s just going from strength to strength, so we’re really happy about how it’s turned out,” Hannah Mary adds. “The Scandinavian culture we talked about trying to introduce – of sauna and the outdoors – is something that is a natural fit for Shetland.”
